He was first licensed 00:05:00.379 --> 00:05:06.379 in 1961 with a novice license WN8ADB at age 14 00:05:06.379 --> 00:05:10.019 in Cincinnati, Ohio. He upgraded to general class 00:05:10.019 --> 00:05:12.459 in about two months and his call sign changed 00:05:12.459 --> 00:05:16.850 to WA8ADB. and he operated as Portable Zero in 00:05:16.850 --> 00:05:20.050 the mid 70s out of Colorado and now lives there 00:05:20.050 --> 00:05:23.050 just east of Fort Collins. He upgraded to Advanced 00:05:23.050 --> 00:05:26.790 Nextra in the 80s and got his current call sign 00:05:26.790 --> 00:05:31.410 NC0B. In 1974 Rob founded Sherwood Engineering 00:05:31.410 --> 00:05:34.089 offering Drake radio upgrades and he started 00:05:34.089 --> 00:05:40.500 testing transceivers. in 1976 which now total 00:05:40.500 --> 00:05:44.139 well over 100 and that information is available 00:05:44.139 --> 00:05:49.160 at his website nc0b .com or Sherwood engineering's 00:05:49.160 --> 00:05:58.139 website sherweng .com and Rob you've been a very 00:05:58.139 --> 00:06:01.779 popular guest on the show and earlier tonight 00:06:01.779 --> 00:06:05.100 when I was actually talking to a friend of yours 00:06:06.259 --> 00:06:10.519 I said that Rob Sherwood was the EF Hutton of 00:06:10.519 --> 00:06:15.560 HamTalk Live. When Rob speaks, people listen. 00:06:16.399 --> 00:06:20.019 So welcome back to the show. Well, thank you, 00:06:20.079 --> 00:06:22.560 Neil. And good evening. By the way, Bedford in 00:06:22.560 --> 00:06:26.139 Indiana is where my Sherwood family farm still 00:06:26.139 --> 00:06:30.300 is over over a hundred years. Oh, wow. Yeah. 00:06:30.420 --> 00:06:34.480 And you're just just down the road here and I'm 00:06:34.480 --> 00:06:37.779 looking forward to Scott and Jill pulling in 00:06:37.779 --> 00:06:41.660 here next week and get to hopefully visit with 00:06:41.660 --> 00:06:45.759 them a little bit and hopefully the ham fest 00:06:45.759 --> 00:06:50.879 goes well there. But yeah, it is just about 25 00:06:50.879 --> 00:06:54.279 minutes down the road. All right. Small world. 00:06:54.660 --> 00:06:58.540 Yeah. And all the Cincinnati connections. I got 00:06:58.540 --> 00:07:00.939 a little bit of that tonight. We're talking with 00:07:01.520 --> 00:07:04.600 next one of next week's guests actually Jay a 00:07:04.600 --> 00:07:09.040 Drake Kate CJ Y and Was telling me you all went 00:07:09.040 --> 00:07:12.360 to high schools that were like next to each other 00:07:12.360 --> 00:07:17.779 and and And basically grew up together. Oh Yeah, 00:07:17.779 --> 00:07:19.980 it certainly goes back to high school days and 00:07:19.980 --> 00:07:22.939 actually one time before I could even drive I 00:07:22.939 --> 00:07:24.500 was out with this whole gang and they were a 00:07:24.500 --> 00:07:26.959 little bit older than I am by a few years and 00:07:26.959 --> 00:07:30.100 My parents didn't know where I was once I got 00:07:30.100 --> 00:07:33.399 home a little bit late, so it was kind of funny. 00:07:33.620 --> 00:07:35.579 But we had a great time visiting radio stations 00:07:35.579 --> 00:07:39.939 in the middle of the night. Well, Jay is going 00:07:39.939 --> 00:07:42.839 to be on next week along with Lee Hite, Kate 00:07:42.839 --> 00:07:46.680 CLI talking about the Drake exhibit over at the 00:07:46.680 --> 00:07:50.699 Voice of America Museum of Broadcasting in Westchester, 00:07:50.899 --> 00:07:53.560 which is northern Cincinnati, Ohio. So we'll 00:07:53.560 --> 00:07:55.939 be talking about that a little bit later. But 00:07:55.939 --> 00:07:58.970 tonight we want to talk about some of the some 00:07:58.970 --> 00:08:03.829 of the modern gear. You were here in January 00:08:03.829 --> 00:08:09.089 of 2018. It's been way too long. The ICOM 7610 00:08:09.089 --> 00:08:11.670 had just arrived on the scene. I believe you 00:08:11.670 --> 00:08:15.850 had tested it but hadn't run a contest with it 00:08:15.850 --> 00:08:19.329 yet, if I remember correctly. And there's all 00:08:19.329 --> 00:08:22.610 kinds of new radios that have been released since 00:08:22.610 --> 00:08:27.100 then. And I know you've got an update from last 00:08:27.100 --> 00:08:32.639 time, too, on the ICOM 7300 to talk about. So 00:08:32.639 --> 00:08:35.860 we'll get that in here in a little bit. But tell 00:08:35.860 --> 00:08:38.580 us about the new radios that have been on the 00:08:38.580 --> 00:08:44.279 scene since the release of the 7610. Well, actually, 00:08:44.399 --> 00:08:46.919 because I did listen to our chat from two years 00:08:46.919 --> 00:08:52.210 ago. The 7610 came up. My wife drove it up just 00:08:52.210 --> 00:08:55.149 in time to hook it up for the first time in a 00:08:55.149 --> 00:08:56.970 contest. So I just barely got it on the air. 00:08:57.450 --> 00:09:00.549 But since then, I have two of them. And so, for 00:09:00.549 --> 00:09:02.710 instance, CQ Worldwide was just last weekend. 00:09:03.169 --> 00:09:07.309 And I had the two 7610s and the TS890S and had 00:09:07.309 --> 00:09:11.070 a ball. Conditions are amazing after certainly 00:09:11.070 --> 00:09:14.590 a dearth of sunspots. So the contest gods were 00:09:14.590 --> 00:09:20.340 on our favor this time. I unfortunately was tied 00:09:20.340 --> 00:09:23.940 up with family stuff and wasn't able to get on, 00:09:24.039 --> 00:09:27.799 but I hear 15 and 10 was just a pleasant surprise. 00:09:28.659 --> 00:09:32.139 Well, I had 77 contacts on 10 and I think 261 00:09:32.139 --> 00:09:36.720 on 15, so it was a ball. Oh, that sounds great. 00:09:37.379 --> 00:09:42.860 Well, tell us a little bit about the 76 -10 now 00:09:42.860 --> 00:09:47.120 that you've got a second one. You've had a chance 00:09:47.120 --> 00:09:52.019 to really put it through the... Oh, what's the 00:09:52.019 --> 00:09:54.360 word I'm looking for? I've lost my word here. 00:09:54.460 --> 00:09:58.320 You've put it through the paces. Right. Well, 00:09:58.320 --> 00:10:01.299 the reason I have two and actually that plus 00:10:01.299 --> 00:10:03.580 the Kenwood is I have three operating positions 00:10:03.580 --> 00:10:06.360 here at the contest station. So I changed bands 00:10:06.360 --> 00:10:08.799 by changing chairs. So like during the daytime, 00:10:08.980 --> 00:10:13.559 I had 10, 15 and 20 set up on the three different 00:10:13.559 --> 00:10:17.360 radios. The thing that I really like about this 00:10:17.360 --> 00:10:20.179 7610 that I don't need to use very often myself, 00:10:20.279 --> 00:10:24.259 but the noise reduction is very nice. That's 00:10:24.259 --> 00:10:26.480 probably the first radio that I've ever, that 00:10:26.480 --> 00:10:30.500 in the 7300, used the noise reduction. And then 00:10:30.500 --> 00:10:33.539 of course the noise blanking is there too. Of 00:10:33.539 --> 00:10:36.100 course it's got a big screen and very simple 00:10:36.100 --> 00:10:39.139 to use and you don't have to go into a lot of 00:10:39.139 --> 00:10:42.120 menus on a daily basis. So it's worked out very 00:10:42.120 --> 00:10:45.519 well and I've had them, actually both of them 00:10:45.519 --> 00:10:49.340 were produced or at least sold in December of 00:10:49.340 --> 00:10:51.960 the first year they shipped here. So they both 00:10:51.960 --> 00:10:54.919 been around, well, just coming up on two years. 00:10:56.879 --> 00:10:59.620 And I know you mentioned that you had an update 00:10:59.620 --> 00:11:03.000 on the 7300 from last time that you wanted to 00:11:03.000 --> 00:11:05.700 make sure to get in. So let's talk a little bit 00:11:05.700 --> 00:11:09.610 about it. Okay, and I think that's a fantastic 00:11:09.610 --> 00:11:12.169 radio whether it's your first radio or you got 00:11:12.169 --> 00:11:15.570 several radios. It's just a wonderful box Well 00:11:15.570 --> 00:11:19.809 when it shipped the something called IP plus 00:11:20.360 --> 00:11:24.279 which is a dithering method of linearizing the 00:11:24.279 --> 00:11:27.840 ADC chip, the analog to digital chip, well, it 00:11:27.840 --> 00:11:30.320 caused the noise floor to degrade, about between 00:11:30.320 --> 00:11:34.179 11 and 13 dB. But ICOM fixed that. I don't know 00:11:34.179 --> 00:11:36.159 the exact serial number when that happened. It 00:11:36.159 --> 00:11:39.080 was a long time ago now. So my first one was 00:11:39.080 --> 00:11:42.519 a serial number 1 ,400 range. But then I bought 00:11:42.519 --> 00:11:44.840 a second one, maybe like a year later, it was 00:11:44.840 --> 00:11:47.600 like 12 ,000 and something. And then a friend 00:11:47.600 --> 00:11:50.500 of mine in Alaska has one at the 10 ,000 serial 00:11:50.500 --> 00:11:52.500 number range and his is fine. So I don't know 00:11:52.500 --> 00:11:54.500 when that happened, but of course now they've 00:11:54.500 --> 00:11:58.879 sold over like 45 ,000 worldwide. So that issue 00:11:58.879 --> 00:12:02.740 that really was not a deal killer at all, but 00:12:02.740 --> 00:12:06.740 that's been fixed. Okay. Very good. Yeah. I remember 00:12:06.740 --> 00:12:09.799 that was a big deal, especially if you were, 00:12:09.799 --> 00:12:13.100 uh, Gonna do like field day or something with 00:12:13.100 --> 00:12:16.919 it and I remember using Hours at school for that 00:12:16.919 --> 00:12:22.179 and actually it worked just fine. So That sounds 00:12:22.179 --> 00:12:25.639 like that's been taken care of well, what are 00:12:25.639 --> 00:12:29.600 some of the other Some of the other rigs Actually, 00:12:29.600 --> 00:12:34.059 I guess while we're on the icon bit here I know 00:12:34.059 --> 00:12:37.500 you you have a 705 on the way, but you've been 00:12:37.500 --> 00:12:41.090 able to get some numbers on it and Um, so let's 00:12:41.090 --> 00:12:43.009 talk a little bit about it while we're on the 00:12:43.009 --> 00:12:47.110 ICOM thread here. Okay. Well, I'd hope to get 00:12:47.110 --> 00:12:49.669 one from hammered to outlet in Denver on Wednesday, 00:12:50.269 --> 00:12:51.970 so I could throw it through the lab in a hurry. 00:12:52.110 --> 00:12:54.129 And that actually didn't come in until today, 00:12:54.129 --> 00:12:58.590 but I was already halfway to, uh, this QTH and, 00:12:58.590 --> 00:13:01.669 uh, so I'll get it on Tuesday. I did get to talk 00:13:01.669 --> 00:13:06.029 to a K zero MD, Scott Wright, who, uh, publishes. 00:13:06.190 --> 00:13:09.750 national contest journal through QST. And of 00:13:09.750 --> 00:13:12.049 course, if you subscribe to QST and are a league 00:13:12.049 --> 00:13:15.750 member, you can now get that downloaded as a 00:13:15.750 --> 00:13:20.009 PDF. So he's been using it a short time. He actually 00:13:20.009 --> 00:13:23.429 ran some sort of a ready contest with it. Now, 00:13:23.429 --> 00:13:26.210 Scott has, well, let's say a pretty good tower. 00:13:26.370 --> 00:13:29.149 It's 130 feet tall. And the whole tower rotates 00:13:29.149 --> 00:13:31.970 and he's got stacks on that tower. And he had 00:13:31.970 --> 00:13:34.889 the little 705 hooked up to his fancy antenna. 00:13:35.799 --> 00:13:38.320 He was quite happy with it. I got some numbers 00:13:38.320 --> 00:13:40.779 out of a friend in Europe. And it looks like 00:13:40.779 --> 00:13:42.379 the numbers are going to be pretty much in the 00:13:42.379 --> 00:13:45.679 ballpark of the 7300 as far as noise floor and 00:13:45.679 --> 00:13:48.519 dynamic range and things like that. So it looks 00:13:48.519 --> 00:13:51.059 like it's going to be a great little QRP rig. 00:13:51.700 --> 00:13:54.460 And actually, I'm going to run it, not QRP. I'll 00:13:54.460 --> 00:13:58.580 let it drive my off amplifier in the ARRL contest 00:13:58.580 --> 00:14:03.850 in December. 160 meter CW, the 10 meter CW and 00:14:03.850 --> 00:14:07.669 single sideband and probably the W1BB 160 meter 00:14:07.669 --> 00:14:10.190 contest. So I'm going to have fun with it, uh, 00:14:10.210 --> 00:14:13.769 driving in a linear. Oh, okay. Very good. Yeah. 00:14:13.769 --> 00:14:17.769 Uh, Scott has, uh, has raved about it and said 00:14:17.769 --> 00:14:20.529 that, uh, he can't tell the difference in the 00:14:20.529 --> 00:14:24.289 receiver between that and a 76 10 and that that's, 00:14:24.289 --> 00:14:28.210 that's pretty impressive. We did a little video 00:14:28.210 --> 00:14:30.649 back and forth for about 45 minutes a couple 00:14:30.649 --> 00:14:33.049 of days ago with Scott and that was finally seeing 00:14:33.049 --> 00:14:36.230 his shack and Him tune in the radio. So that 00:14:36.230 --> 00:14:38.149 was that's as close to I've got my hand on a 00:14:38.149 --> 00:14:40.870 knob, but by Tuesday I'll have my hand on a knob 00:14:40.870 --> 00:14:45.009 All right. Well, we look forward to To hearing 00:14:45.009 --> 00:14:47.909 about that and and I guess is like I said as 00:14:47.909 --> 00:14:51.409 long as we're on the icon thread here The IC 00:14:51.409 --> 00:14:55.129 9700 is one that's been out since then too. So 00:14:55.129 --> 00:14:57.990 we'll talk a little bit about it Sure, well, 00:14:58.049 --> 00:15:04.129 I have one of those. And I retired my ICOM 275H. 00:15:04.570 --> 00:15:07.250 That was a 100 watt multi -mode, two meters only. 00:15:07.590 --> 00:15:10.450 Great front end, nice little radio. Had pass 00:15:10.450 --> 00:15:12.970 band tuning, which they later unfortunately went 00:15:12.970 --> 00:15:17.370 away due to some dispute with patents. But I 00:15:17.370 --> 00:15:20.909 did replace the 275H with the 9700, and I love 00:15:20.909 --> 00:15:27.299 it. Now and it works pretty much like all all 00:15:27.299 --> 00:15:30.059 the rest so you figure out all the functions 00:15:30.059 --> 00:15:34.940 why you're in pretty good shape and Full disclosure 00:15:34.940 --> 00:15:39.320 ICOM is a sponsor of the show so we'll get that 00:15:39.320 --> 00:15:42.460 in there But then you've got some some other 00:15:42.460 --> 00:15:45.340 rigs that are on here. One of the newer ones 00:15:45.340 --> 00:15:51.809 is the Yezu FTDX 101D And I'm looking at your 00:15:51.809 --> 00:15:54.710 table right now and it's sitting at the top. 00:15:55.909 --> 00:16:00.169 And I was lucky in time before, you know, Dayton 00:16:00.169 --> 00:16:02.889 Zoom, we'll call it, or Hamm Contest University 00:16:02.889 --> 00:16:07.870 Zoom method. Hamm in New York loaned me the rig 00:16:07.870 --> 00:16:11.590 in time for that. I ran it through the lab. Of 00:16:11.590 --> 00:16:14.370 course, there was a recall early on and all the 00:16:14.370 --> 00:16:16.950 rigs had to go back to California. So it got 00:16:16.950 --> 00:16:20.309 the overshoot update. ALC overshoot update and 00:16:20.309 --> 00:16:22.730 it came back and tested it again and that was 00:16:22.730 --> 00:16:24.950 corrected. And then it went back to its owner. 00:16:25.090 --> 00:16:27.730 I got to listen to it a bit in Denver, but I 00:16:27.730 --> 00:16:30.850 didn't get to use a lot on the air, but it certainly, 00:16:31.110 --> 00:16:36.009 Yezu had made a major strides in the cleanliness 00:16:36.009 --> 00:16:39.129 of the synthesizer, which is outstanding. The 00:16:39.129 --> 00:16:40.990 Dymec range obviously is really outstanding. 00:16:41.090 --> 00:16:42.850 It happened to be the top of the list by a few 00:16:42.850 --> 00:16:46.460 DB over a few other very fine rigs. So it was 00:16:46.460 --> 00:16:49.980 great to see really get to the top of their game. 00:16:50.340 --> 00:16:53.940 So I'm sure it's been a good seller. And I kind 00:16:53.940 --> 00:16:56.679 of watched the Groups .io group and a lot of 00:16:56.679 --> 00:17:02.360 chatter on that. And then we've got the Flex, 00:17:02.480 --> 00:17:05.819 which has been there for a while, and the ICOM 00:17:05.819 --> 00:17:10.140 receiver, which we kind of expect to be pretty 00:17:10.140 --> 00:17:13.420 similar. And just cruising down here, we've got 00:17:13.420 --> 00:17:20.009 the Kenwood TS. 890 correct and actually I was 00:17:20.009 --> 00:17:24.730 an owner of the TS 990 for three years and unfortunately 00:17:24.730 --> 00:17:28.569 a really close lightning strike that took out 00:17:28.569 --> 00:17:33.069 several things it took out the 990 so then after 00:17:33.440 --> 00:17:35.940 There was the 890 didn't exist then at that point. 00:17:36.160 --> 00:17:39.059 And then I think the 890 has been out about two 00:17:39.059 --> 00:17:41.720 years. So I got one of those and that's over 00:17:41.720 --> 00:17:44.539 here to my right right now. The thing I like 00:17:44.539 --> 00:17:49.119 about the 890 versus any other standalone radio 00:17:49.119 --> 00:17:53.019 with a direct sampling band scope is the way 00:17:53.019 --> 00:17:57.660 it tunes. As I tune the radio, the waterfall 00:17:57.660 --> 00:18:01.500 doesn't slew off at an angle. The band scope 00:18:01.500 --> 00:18:04.220 doesn't sort of fade out if I've got averaging 00:18:04.220 --> 00:18:07.740 on. And so it makes it really easy. I call it 00:18:07.740 --> 00:18:10.640 like shooting fish in a barrel that works particularly 00:18:10.640 --> 00:18:14.279 CW contact tax in a contest, maybe the station 00:18:14.279 --> 00:18:18.220 every three or 400 Hertz. And so I use the 890 00:18:18.220 --> 00:18:23.000 with a 10 kilohertz span on 160, for instance. 00:18:23.000 --> 00:18:25.500 And I think on 10 meters, probably a 10 kilohertz 00:18:25.500 --> 00:18:30.180 span. And I'll just see the signal on the waterfall. 00:18:30.440 --> 00:18:35.099 I centered in the passband. The passband width 00:18:35.099 --> 00:18:37.839 highlights itself while you're tuning. So you 00:18:37.839 --> 00:18:39.940 just drop that signal right in the middle of 00:18:39.940 --> 00:18:42.119 your passband, whatever bandwidth you've chosen, 00:18:42.720 --> 00:18:45.420 and you're dead on frequency, and you work the 00:18:45.420 --> 00:18:46.880 guy. And then the sooner you're done with that, 00:18:46.880 --> 00:18:50.859 I'm doing S &P. I'm not running search and pounce. 00:18:51.039 --> 00:18:53.779 So I just tune the next station. So it's just 00:18:53.779 --> 00:18:56.559 a fantastic the way the waterfall and the band 00:18:56.559 --> 00:18:59.329 scope work. So that's. From my standpoint of 00:18:59.329 --> 00:19:02.569 contesting, that's my favorite way to do CW contesting 00:19:02.569 --> 00:19:07.430 with the way the waterfall works. Uh, the next 00:19:07.430 --> 00:19:14.009 one on the list is the Apache 7 ,000 DLE. That's 00:19:14.009 --> 00:19:17.309 been interesting because Apache is, of course 00:19:17.309 --> 00:19:19.930 it's open source software, which is different 00:19:19.930 --> 00:19:22.910 than everybody else's software. That's a proprietary. 00:19:23.589 --> 00:19:26.480 And so a lot of really smart hams, right? the 00:19:26.480 --> 00:19:30.460 software for the radio, the DSP software, and 00:19:30.460 --> 00:19:33.500 what's called Pure Signal, that's the pre -distortion 00:19:33.500 --> 00:19:36.259 that makes it the cleanest rig on the air, period. 00:19:36.839 --> 00:19:40.740 That's written by Warren Pratt, NR0V, and he 00:19:40.740 --> 00:19:43.500 lives in Loveland, Colorado. It's about 30 miles 00:19:43.500 --> 00:19:47.579 from me right now. So I use that in a contest, 00:19:47.920 --> 00:19:52.220 160 contest, about a year and a half ago, approaching 00:19:52.220 --> 00:19:57.220 two years, and the He's got something called 00:19:57.220 --> 00:19:59.539 a spectral noise blanker. Now, normally when 00:19:59.539 --> 00:20:02.099 we're in a contest, you know, a zillion stations 00:20:02.099 --> 00:20:05.380 on the band, if we do have a noise issue, you 00:20:05.380 --> 00:20:07.680 turn on the blanker and usually they false trigger 00:20:07.680 --> 00:20:09.380 and they just cause more trouble than they're 00:20:09.380 --> 00:20:13.200 worth. But he has this amazing spectral noise 00:20:13.200 --> 00:20:17.339 blanker that it only looks at the bandwidth that 00:20:17.339 --> 00:20:20.259 you've set on your transceiver, whether it's 00:20:20.259 --> 00:20:23.380 sideband or CW, 500 hertz or 2 .4 or whatever 00:20:23.380 --> 00:20:27.140 the bandwidth is you've chosen. And it makes 00:20:27.140 --> 00:20:30.259 an approximation of the amount of signal that's 00:20:30.259 --> 00:20:33.160 there in between the noise pulses and fills in 00:20:33.160 --> 00:20:36.099 the blanks. And it's just amazing. So the software 00:20:36.099 --> 00:20:38.880 is great. And I really want to commend them on 00:20:38.880 --> 00:20:42.660 their transmit signal. I actually am on a 75 00:20:42.660 --> 00:20:47.240 meter chit chat, 8 o 'clock each day of the week, 00:20:47.660 --> 00:20:52.390 on a 3 ,652 that's around this area. and some 00:20:52.390 --> 00:20:54.609 neighboring states. And the stations that are 00:20:54.609 --> 00:20:56.910 all running Apache, when you look at them on 00:20:56.910 --> 00:20:59.410 the band scope, they're just straight up and 00:20:59.410 --> 00:21:02.109 down. Absolutely, there isn't any fuzz on it. 00:21:02.509 --> 00:21:05.329 So you can tell who's on an Apache and who's 00:21:05.329 --> 00:21:07.789 not. It's just amazing. And this is good for 00:21:07.789 --> 00:21:10.529 everyone because anytime we can narrow our bandwidth 00:21:10.529 --> 00:21:14.250 from a splatter standpoint, and of course, every 00:21:14.250 --> 00:21:18.670 transceiver has a less than perfect because perfect 00:21:18.670 --> 00:21:21.660 doesn't exist in the radio world. And Class A 00:21:21.660 --> 00:21:24.039 is pretty much gone. They used to offer Class 00:21:24.039 --> 00:21:27.940 A on two or three rigs, but not any longer. So 00:21:27.940 --> 00:21:30.859 anyway, this pure signal, pre -distortion. And 00:21:30.859 --> 00:21:33.920 of course, you can also sample the output of 00:21:33.920 --> 00:21:36.880 your linear amplifier when you're running full 00:21:36.880 --> 00:21:39.119 power or 500 watts or whatever your amplifier 00:21:39.119 --> 00:21:42.759 is and feed that back into the rig. And it corrects 00:21:42.759 --> 00:21:47.740 any distortion by 20 or 30 dB. It's just amazing. 00:21:49.650 --> 00:21:53.690 Well, let's see what else we have here we have 00:21:53.690 --> 00:22:00.589 the flex 6400 Well the 64 and the 66 pretty much 00:22:00.589 --> 00:22:03.589 are right next to each other on my table There's 00:22:03.589 --> 00:22:06.730 no I think they're 1db different which is insignificant. 00:22:06.730 --> 00:22:09.970 Obviously. It's just uh, you know that so you 00:22:09.970 --> 00:22:12.609 could put that down to a sample variation or 00:22:12.609 --> 00:22:16.549 even the experimental error, but of course they 00:22:16.549 --> 00:22:19.910 do operate with a computer just like the Apache 00:22:19.910 --> 00:22:24.529 and so that's the difference between like the 00:22:24.529 --> 00:22:27.210 Kenwood and the Icom and the Yezu which are standalone 00:22:27.210 --> 00:22:30.309 so you do need the computer. Some of the people 00:22:30.309 --> 00:22:35.190 run their Flex with an iPad so that's flexible 00:22:35.190 --> 00:22:38.130 and of course they put a lot of emphasis on remote. 00:22:38.599 --> 00:22:40.900 And actually, I was during Siki Worldwide, I 00:22:40.900 --> 00:22:43.440 think I was on 15 meters and talking to a station 00:22:43.440 --> 00:22:46.960 that I think was zone 33. But the operator was 00:22:46.960 --> 00:22:50.339 really in Finland and he said, Hi, Rob, you should 00:22:50.339 --> 00:22:53.220 put my rig on your test bench. He was making 00:22:53.220 --> 00:22:56.220 a joke, of course. And he said, I'm in Finland, 00:22:56.359 --> 00:22:59.559 but the transmitter transceiver is a flex and 00:22:59.559 --> 00:23:02.339 it's I think it was zone 33. But anyway, it was 00:23:02.339 --> 00:23:04.779 hundreds of miles away. So that was kind of fun. 00:23:07.269 --> 00:23:11.190 Let's see I'm looking through the list here and 00:23:11.190 --> 00:23:16.430 I think we've got one More that we have not hit 00:23:16.430 --> 00:23:26.970 on And that would be where did it go Looking 00:23:26.970 --> 00:23:33.950 here all the lab the lab 599 the TX 500. Oh, 00:23:33.950 --> 00:23:36.680 yes And that's a QRP rig, 10 watts. Of course, 00:23:36.700 --> 00:23:39.839 you can run five watts. And I borrowed it from 00:23:39.839 --> 00:23:42.779 a very nice amateur that loaned it to me for 00:23:42.779 --> 00:23:44.740 several days. I ran it through the lab. It's 00:23:44.740 --> 00:23:47.759 on my website. It's the most recent update. And 00:23:47.759 --> 00:23:53.299 it's very sturdily made. It's like machined aluminum 00:23:53.299 --> 00:23:56.900 clamshell, half and half. It has a band scope 00:23:56.900 --> 00:24:01.500 built in and very easy to use. The numbers are 00:24:01.500 --> 00:24:05.839 quite fine. I think it came up at 79. And really, 00:24:05.960 --> 00:24:09.460 for years, I used to say NWAJI, time route. So 00:24:09.460 --> 00:24:12.700 you know, 80 dB radios are adequate almost all 00:24:12.700 --> 00:24:14.240 the time. And I've kind of moved that number 00:24:14.240 --> 00:24:17.039 up to 85 because now we probably have two or 00:24:17.039 --> 00:24:21.339 three dozen radios that are 85 to the 110 range. 00:24:21.740 --> 00:24:24.740 So it looks like a cute little radio. I just 00:24:24.740 --> 00:24:27.539 did use it in the lab. I didn't climb a soda 00:24:27.539 --> 00:24:30.180 mountain or something like that. But it looks 00:24:30.180 --> 00:24:32.700 very rugged and if you got some sprinkles on 00:24:32.700 --> 00:24:34.380 it, it's not going to die in a little bit of 00:24:34.380 --> 00:24:38.640 rain. All right. Very good. Well, we're looking 00:24:38.640 --> 00:24:43.759 at the tables here at nc0b .com and there's a 00:24:43.759 --> 00:24:47.799 yellow bar down at the bottom. You click on that 00:24:47.799 --> 00:24:53.019 and it puts all of these transceivers and receivers 00:24:53.019 --> 00:25:00.700 that you have analyzed. In order and I know you 00:25:00.700 --> 00:25:03.660 always want to talk about the order and we should 00:25:03.660 --> 00:25:09.660 do that. The more extensive. uh, interview about 00:25:09.660 --> 00:25:12.420 all the numbers and what all the numbers mean 00:25:12.420 --> 00:25:16.599 and, and all that, um, is on the previous episode. 00:25:16.599 --> 00:25:19.660 So you go back and, and, and check that out if 00:25:19.660 --> 00:25:22.339 you're interested in digging into the numbers 00:25:22.339 --> 00:25:25.160 and what these ratings are, but give everybody 00:25:25.160 --> 00:25:29.380 just kind of the quick, uh, the quick spiel about 00:25:29.380 --> 00:25:33.339 how you've arranged these in order and, and what 00:25:33.339 --> 00:25:36.839 that really means. Sure great and by the way, 00:25:36.920 --> 00:25:38.799 just if you go to the home page There's a banner 00:25:38.799 --> 00:25:40.960 that crawls across the top of the screen you 00:25:40.960 --> 00:25:43.740 click on that banner it goes to the the table 00:25:43.740 --> 00:25:47.480 as in addition to the one at the bottom and also 00:25:47.480 --> 00:25:49.619 I think there's a broken link at the bottom on 00:25:49.619 --> 00:25:54.380 an explanation but on the on the Table page is 00:25:54.380 --> 00:25:57.000 not broken. Am I webmasters gonna fix that but 00:25:57.000 --> 00:26:00.720 but anyway, so you have to rank the radios by 00:26:00.720 --> 00:26:04.619 some parameter and the reason it's sorted by 00:26:04.670 --> 00:26:09.190 close in dynamic range is the reason I started 00:26:09.190 --> 00:26:12.769 testing radios back there in the mid -70s. I 00:26:12.769 --> 00:26:16.730 had a radio that, with the older standard test 00:26:16.730 --> 00:26:20.930 that came out in 1975, which meant the two -tone 00:26:20.930 --> 00:26:25.730 test for the dynamic range was 20 kilohertz. 00:26:26.289 --> 00:26:28.750 And that was OK for radios designed in the 50s 00:26:28.750 --> 00:26:32.480 and 60s and maybe most of them in the early 70s, 00:26:32.700 --> 00:26:35.059 but it really didn't work once we had roofing 00:26:35.059 --> 00:26:38.980 filters. Because once the roofing filter came 00:26:38.980 --> 00:26:45.180 along, you had a lot of gain within the bandwidth 00:26:45.180 --> 00:26:47.460 of the roofing filter, and selectivity was way 00:26:47.460 --> 00:26:50.880 downstream. And if you tested it at 20 kilohertz, 00:26:50.980 --> 00:26:53.720 that means those two signals are 20 kilohertz 00:26:53.720 --> 00:26:57.240 down the band and 40, or 20 kilohertz and 40 00:26:57.240 --> 00:27:00.000 kilohertz up the band. Well, you're not testing 00:27:00.000 --> 00:27:03.480 anything but the first mixer and it may be passive 00:27:03.480 --> 00:27:05.660 intermod in the roofing filter or something like 00:27:05.660 --> 00:27:08.579 that. But once the signals get inside the roofing 00:27:08.579 --> 00:27:11.359 filter and really for 25 years, all the roofing 00:27:11.359 --> 00:27:14.039 filters, like 99 % of the roofing filters were 00:27:14.039 --> 00:27:17.480 15 kilohertz wide, you can have a lot of CW signals 00:27:17.480 --> 00:27:21.599 in that bandwidth. It's really mostly a CW issue 00:27:21.599 --> 00:27:27.309 and RTTY for sideband most of the time. our adjacent 00:27:27.309 --> 00:27:31.009 channel splatter, the intermods, even if we have 00:27:31.009 --> 00:27:33.329 a relatively clean signal, we still have a width 00:27:33.329 --> 00:27:36.029 that's approaching 10 kilohertz if we're going 00:27:36.029 --> 00:27:40.529 in like 60 dB down. So most of the time on sideband, 00:27:40.950 --> 00:27:42.930 if a station is three or four kilohertz away, 00:27:44.130 --> 00:27:46.089 the limit isn't going to be the dynamic range 00:27:46.089 --> 00:27:49.879 of the radio, but it'll be to whatever. unintended 00:27:49.879 --> 00:27:52.960 splatter comes from the transceiver. But on CW, 00:27:52.960 --> 00:27:54.720 of course, we don't have that. We do have key 00:27:54.720 --> 00:27:58.839 clicks, which can be an issue. And maybe in a 00:27:58.839 --> 00:28:00.940 field day environment, transmitted composite 00:28:00.940 --> 00:28:03.660 noise. But for the most part, the signals are 00:28:03.660 --> 00:28:07.240 pretty narrow. So if we have 15 kilohertz worth 00:28:07.240 --> 00:28:11.140 of signals, which could be 50 signals, it can 00:28:11.140 --> 00:28:15.140 really cause havoc. I started testing at 2 kHz 00:28:15.140 --> 00:28:18.619 spacing instead of 20, and I did that ever since 00:28:18.619 --> 00:28:22.640 about 1976. And eventually the league got there. 00:28:22.819 --> 00:28:25.160 It took a long time, but they test the 2 kHz 00:28:25.160 --> 00:28:30.180 now just like I do. So if you're a CW op into 00:28:30.180 --> 00:28:33.859 contest, de -expedition, pile -up band type of 00:28:33.859 --> 00:28:38.339 conditions, or RIDI, That's really the number 00:28:38.339 --> 00:28:40.940 you need to look at. Now, sometimes I get asked, 00:28:41.019 --> 00:28:43.700 well, why don't you sort it by sensitivity or 00:28:43.700 --> 00:28:46.819 noise floor? But I just gave a presentation in 00:28:46.819 --> 00:28:49.460 the last few weeks and showed some data on, well, 00:28:49.559 --> 00:28:54.160 the R390A has a sensitivity of 0 .2 microvolts. 00:28:54.599 --> 00:28:58.380 The R4C has a sensitivity of. 0 .2 microvolts. 00:28:58.640 --> 00:29:02.799 The K3S with preamp number one turned on, sensitivity 00:29:02.799 --> 00:29:06.720 of 0 .2 microvolts. Now sensitivity is a sideband 00:29:06.720 --> 00:29:08.680 measurement. And then if you look at the noise 00:29:08.680 --> 00:29:11.980 floor, which is the way we look at for the CW 00:29:11.980 --> 00:29:14.119 measurements, they're all within 1 dB of each 00:29:14.119 --> 00:29:17.359 other. So the radios today are phenomenal from 00:29:17.359 --> 00:29:20.299 that standpoint. You can hardly buy a radio that's 00:29:20.299 --> 00:29:24.740 not sensitive enough. For that matter, we really 00:29:24.740 --> 00:29:27.180 have too much on the lower bands. Radios today 00:29:27.180 --> 00:29:29.500 are designed for 10 meters and now 6 meters. 00:29:29.700 --> 00:29:32.880 Everybody's radio covers 6 meters today. And 00:29:32.880 --> 00:29:36.819 so you've got amazing sensitivity for 12, 10, 00:29:36.839 --> 00:29:40.519 and 6. But once we're down on 160 or 80, the 00:29:40.519 --> 00:29:44.180 band noise at night is like 30 dB higher than 00:29:44.180 --> 00:29:46.680 band noise at the daytime it is on 10 meters. 00:29:47.119 --> 00:29:49.359 So we've got all sorts of sensitivity that goes 00:29:49.359 --> 00:29:53.690 to waste. You should be running attenuation at 00:29:53.690 --> 00:29:56.369 night for multiple reasons that I do go to in 00:29:56.369 --> 00:29:59.450 my talk. So that's the reason it's sorted that 00:29:59.450 --> 00:30:01.230 way. Of course, there's other information. How 00:30:01.230 --> 00:30:03.849 clean is the synthesizer? That's important for 00:30:03.849 --> 00:30:07.210 like 20 or 25 years that synthesizers were really 00:30:07.210 --> 00:30:10.430 the limit. But now the synthesizer in the new 00:30:10.430 --> 00:30:14.609 Yezu, in the new Kenwood, the direct sampling 00:30:14.609 --> 00:30:17.900 radios, if you put a decent. clock oscillator 00:30:17.900 --> 00:30:19.740 in a direct sampling radio. You're not going 00:30:19.740 --> 00:30:22.759 to have a phase noise problem or a reciprocal 00:30:22.759 --> 00:30:26.299 mixing dynamic range problem. So we're really 00:30:26.299 --> 00:30:28.940 amazing condition from that standpoint that we 00:30:28.940 --> 00:30:33.680 didn't have years ago. All right. Well, uh, before 00:30:33.680 --> 00:30:36.720 we go to break here, I do want to, uh, to mention 00:30:36.720 --> 00:30:40.880 that, that you've retired since last time. So 00:30:40.880 --> 00:30:46.750 congratulations on that. And, uh, Are you still 00:30:46.750 --> 00:30:50.269 doing any business? Do you still have any of 00:30:50.269 --> 00:30:53.809 your upgrades available? What's going on with 00:30:53.809 --> 00:30:57.130 the business side of things? Well, we pretty 00:30:57.130 --> 00:31:00.930 much shut it down. I'm 73 and my technician has 00:31:00.930 --> 00:31:05.789 worked with me for 28 years. He's 83. So we just 00:31:05.789 --> 00:31:09.190 decided it's time to call it a day. I happen 00:31:09.190 --> 00:31:12.329 to have two or three mix fours left for the R4C, 00:31:12.349 --> 00:31:15.309 but otherwise everything's gone. The cooling 00:31:15.309 --> 00:31:19.589 kits for the 781 are gone and the little upgrade 00:31:19.589 --> 00:31:23.710 for the NRD535. So, you know, I started all this 00:31:23.710 --> 00:31:27.150 in 1974 and was really kind of surprised. If 00:31:27.150 --> 00:31:30.730 you'd said in 1980 or 1985 that I would be still 00:31:30.730 --> 00:31:35.869 updating Drake R4Cs in 1999 and early 2000, I 00:31:35.869 --> 00:31:38.390 would have said, really? But There was still 00:31:38.390 --> 00:31:41.089 a lot of interest, but at some point I had to 00:31:41.089 --> 00:31:43.109 call it a day, but I've gotten some emails that 00:31:43.109 --> 00:31:48.410 said you cannot quit, you cannot retire. So what 00:31:48.410 --> 00:31:51.849 can you say? Yeah. And we're going to talk about 00:31:51.849 --> 00:31:55.009 those are fours and, uh, and the upgrade a little 00:31:55.009 --> 00:31:58.690 bit next week as well. So we'll save that for 00:31:58.690 --> 00:32:02.089 then, but, uh, but congratulations on the retirement 00:32:02.089 --> 00:32:04.869 and, and we're glad you're still, uh, testing 00:32:04.869 --> 00:32:09.569 and. providing all the data and that gives you 00:32:09.569 --> 00:32:12.710 a little more time to play radio, hopefully, 00:32:12.789 --> 00:32:16.690 anyway. Well, I'm definitely not retiring from 00:32:16.690 --> 00:32:18.970 testing radios. That'll go on as long as I can. 00:32:20.869 --> 00:32:26.089 Well, we appreciate all of that and we really 00:32:26.089 --> 00:32:30.650 like all this information that you provide all 00:32:30.650 --> 00:32:33.390 together in one nice neat little package. It 00:32:33.390 --> 00:32:37.720 makes it very easy to come in and do the receiver 00:32:37.720 --> 00:32:40.579 comparisons. Although, like you said, most of 00:32:40.579 --> 00:32:45.970 them are really, really good these days. Well, 00:32:45.970 --> 00:32:48.269 we're going to take a break. When we come back, 00:32:48.410 --> 00:32:50.990 we'll talk some more with Rob and we'll start 00:32:50.990 --> 00:32:55.890 taking your questions on Twitter and on Spreaker 00:32:55.890 --> 00:33:04.769 and on the phones at 859 -982 -7373.

If I can get this thing to 00:37:19.690 --> 00:37:22.929 answer the phone, uh, or you can tweet us it's 00:37:22.929 --> 00:37:24.989 at ham talk live. And if you're listening to 00:37:24.989 --> 00:37:28.920 us on WTW. or on the podcast edition, you won't 00:37:28.920 --> 00:37:32.099 be able to reach us live since we're doing this 00:37:32.099 --> 00:37:36.739 on Thursday night. And while I try to get the 00:37:36.739 --> 00:37:40.179 phone to answer, we do have a tweet here from 00:37:40.179 --> 00:37:43.139 Dan. He says, hi Rob, Dan Robinson in Maryland 00:37:43.139 --> 00:37:46.380 as someone who benefited from your deep experience 00:37:46.380 --> 00:37:48.719 in the radio field so long. Congratulations on 00:37:48.719 --> 00:37:51.400 your retirement and all the best luck to you. 00:37:51.920 --> 00:37:54.119 A tough question, but if you could line up in 00:37:54.119 --> 00:37:57.900 your head, a ranking of the most sensitive and 00:37:57.900 --> 00:38:04.760 quiet HF receivers, what would that be? OK, well, 00:38:05.079 --> 00:38:07.679 I'm going to answer the question sort of. But 00:38:07.679 --> 00:38:11.260 we have to realize that our receivers are completely 00:38:11.260 --> 00:38:14.480 adequate for sensitivity. But that's the left 00:38:14.480 --> 00:38:17.619 hand column. Well, noise floor, which is in that 00:38:17.619 --> 00:38:20.500 500 Hertz bandwidth, just like you see in QST. 00:38:21.309 --> 00:38:23.809 And then in sort of the middle column, this listed 00:38:23.809 --> 00:38:26.809 as sensitivity. And I put it in microvolts instead 00:38:26.809 --> 00:38:29.949 of dBm, because if you have a radio that goes 00:38:29.949 --> 00:38:34.730 back before 1975, no one heard of dBm in the 00:38:34.730 --> 00:38:38.630 amateur world. So I keep sensitivity in microvolts. 00:38:39.110 --> 00:38:41.030 And you can look at either of those columns. 00:38:41.429 --> 00:38:43.690 And they're not sorted that way. But it's kind 00:38:43.690 --> 00:38:46.610 of a non -issue. Let's look at the first few. 00:38:46.730 --> 00:38:49.780 I've got. Like 10 of them up here on the screen. 00:38:49.780 --> 00:38:52.280 We've got the new Yezu Of course, they've got 00:38:52.280 --> 00:38:54.900 preamp 1 and preamp 2 in some cases They all 00:38:54.900 --> 00:38:58.360 have preamp 1 at least but look at the noise 00:38:58.360 --> 00:39:05.599 floor minus 141 for several 145 139 and on 6 00:39:05.599 --> 00:39:10.500 meters that might be useful on 10 meters probably 00:39:10.500 --> 00:39:15.320 138 is plenty good in a quiet location Now, that's 00:39:15.320 --> 00:39:18.420 the key. Most of us live in an urban environment. 00:39:19.260 --> 00:39:23.679 I would say that band noise, meaning RFI noise 00:39:23.679 --> 00:39:26.239 from all these electronic things we have today, 00:39:27.739 --> 00:39:31.559 line noise, switching power supplies, microprocessors 00:39:31.559 --> 00:39:35.139 in our refrigerator, our washing machine, our 00:39:35.139 --> 00:39:37.559 dishwasher, they all put out racket, your charger 00:39:37.559 --> 00:39:40.719 for your iPhone or whatever. They put out noise. 00:39:41.000 --> 00:39:44.860 Matter of fact, My four towers that are further 00:39:44.860 --> 00:39:48.260 from the house pick up way less noise from my 00:39:48.260 --> 00:39:50.619 own house as the two that are close to my house, 00:39:50.679 --> 00:39:53.300 because I got lucky I have 10 acres and six towers. 00:39:54.420 --> 00:39:56.619 So but if you're in an urban environment like 00:39:56.619 --> 00:40:00.780 I am in Denver, it almost doesn't matter because 00:40:00.780 --> 00:40:04.460 local noise is terrible. I'm a mobile fan and 00:40:04.460 --> 00:40:06.460 when I drive through a town, I might as well 00:40:06.460 --> 00:40:09.820 turn the mobile off. So really don't focus on 00:40:11.250 --> 00:40:14.409 sensitivity or band noise by trying to decide 00:40:14.409 --> 00:40:16.829 on a radio because really all the good radios 00:40:16.829 --> 00:40:21.030 are just fine. All right. Well, let's see here. 00:40:21.070 --> 00:40:25.150 Uh, John W four U S F says, love Rob's antenna 00:40:25.150 --> 00:40:27.730 farm. I am one jealous ham radio operator this 00:40:27.730 --> 00:40:30.230 evening. And there, there was the, you mentioned 00:40:30.230 --> 00:40:32.989 the, the six towers and 10 acres. That that's, 00:40:33.449 --> 00:40:38.599 uh, that's definitely, um, Worthy of being jealous 00:40:38.599 --> 00:40:43.500 Well, I've been here for 13 years my wife said 00:40:43.500 --> 00:40:47.300 you've wanted to do this it was kind of at the 00:40:47.300 --> 00:40:51.059 When the housing market kind of crashed and so 00:40:51.059 --> 00:40:54.500 that was the time and my wife was very supportive 00:40:54.500 --> 00:41:01.579 and off we went Well, that's great Fabulous that 00:41:01.579 --> 00:41:04.760 you can do that. I am in the middle of trying 00:41:04.760 --> 00:41:11.880 to get property to put up one. And maybe today 00:41:11.880 --> 00:41:16.039 was the first step of that. We'll see. But I'm 00:41:16.039 --> 00:41:19.340 fighting that battle. All right. Well, the phone 00:41:19.340 --> 00:41:25.500 is ringing, but I can't answer it. So we'll keep 00:41:25.500 --> 00:41:29.039 trying the tweets here. Go ahead. Let me make 00:41:29.039 --> 00:41:32.860 a comment on the antennas. I consider antennas 00:41:32.860 --> 00:41:36.079 extremely important. If you want to say in order, 00:41:36.360 --> 00:41:38.619 what's most important? Well, location. And maybe 00:41:38.619 --> 00:41:41.860 you can't do anything about that. But I moved 00:41:41.860 --> 00:41:46.179 out in the country. And then antennas and operator 00:41:46.179 --> 00:41:48.380 skill. And you could argue, well, operator skill 00:41:48.380 --> 00:41:50.760 antennas, maybe you'll flip them around. And 00:41:50.760 --> 00:41:54.340 then the radio. So really, put up the best antenna 00:41:54.340 --> 00:41:57.199 you can. On the upper bands, when we can have 00:41:57.199 --> 00:42:00.300 a tri -band or a mono -band or whatever, there's 00:42:00.300 --> 00:42:03.119 nothing more important than the directivity of 00:42:03.119 --> 00:42:07.139 a yagi or a quad or whatever it is. I happen 00:42:07.139 --> 00:42:10.619 to have two yagis per band, like on 20 and 15 00:42:10.619 --> 00:42:14.460 and 10, so they'll be pointed in different directions 00:42:14.460 --> 00:42:17.500 during a contest. It's like two different bands. 00:42:17.559 --> 00:42:20.059 You can't believe the amount of attenuation. 00:42:21.320 --> 00:42:23.579 Maybe you rotate your beam around and you say, 00:42:23.679 --> 00:42:25.880 well, I guess it helps. But when you can flick 00:42:25.880 --> 00:42:28.659 a switch and go between antenna one and antenna 00:42:28.659 --> 00:42:30.900 two in two different directions, it's like two 00:42:30.900 --> 00:42:33.980 different bands. So if you can put a Yagi up 00:42:33.980 --> 00:42:37.539 at 35 feet, that should be your number one priority. 00:42:37.659 --> 00:42:41.760 And of course, higher is better. And you mentioned 00:42:41.760 --> 00:42:45.039 too, while I'm still trying to reboot the phone 00:42:45.039 --> 00:42:48.679 system here, you mentioned too the footnotes. 00:42:49.159 --> 00:42:52.340 There's always footnotes on the table, so let's 00:42:52.340 --> 00:42:55.820 talk a little bit about the footnotes. Good reminder. 00:42:56.599 --> 00:42:59.380 Okay, well, like on that first column with the 00:42:59.380 --> 00:43:02.000 noise floor, the footnote just describes the 00:43:02.000 --> 00:43:04.079 preamp, whether it's on or off and which preamp. 00:43:04.179 --> 00:43:06.880 That's pretty straightforward. The big thing 00:43:06.880 --> 00:43:09.280 is over in the right -hand column, since it is 00:43:09.280 --> 00:43:12.940 sorted by close in a dynamic range, two kilohertz, 00:43:13.320 --> 00:43:15.780 or there's also the 20 kilohertz numbers too. 00:43:16.260 --> 00:43:19.210 If there's a footnote... Read it carefully because 00:43:19.210 --> 00:43:21.590 it may have a big significance. Let's just look 00:43:21.590 --> 00:43:28.190 at the K 3 for instance and It had different 00:43:28.190 --> 00:43:30.929 bandwidths and that different numbers or let 00:43:30.929 --> 00:43:33.769 me find the see if I can find the K X 3 because 00:43:33.769 --> 00:43:40.449 that's an interesting one It has I think three 00:43:40.449 --> 00:43:44.730 footnotes dealing with here it is dealing with 00:43:44.730 --> 00:43:47.510 whether you were in the zero IF version, whether 00:43:47.510 --> 00:43:50.369 you had the quote roofing filter or whether you 00:43:50.369 --> 00:43:53.369 were concerned about the opposite sideband rejection 00:43:53.369 --> 00:43:56.489 because the KX3 is kind of a phasing rig. If 00:43:56.489 --> 00:43:58.309 you guys are as old as I am, you know what a 00:43:58.309 --> 00:44:01.889 20A was. That was a phasing transmitter, but 00:44:01.889 --> 00:44:04.670 you have it's kind of a phasing receiver. So 00:44:04.670 --> 00:44:07.369 the opposite sideband rejection is around 65 00:44:07.369 --> 00:44:10.230 dB. So if you did happen to have a signal just 00:44:10.230 --> 00:44:12.570 on the opposite side band of your beat note on 00:44:12.570 --> 00:44:15.130 CW, let's say you like the 700 hertz beat note 00:44:15.130 --> 00:44:17.269 and you were on the opposite side band at 700 00:44:17.269 --> 00:44:21.250 hertz with a big signal and it was that the rejection 00:44:21.250 --> 00:44:25.590 is 65 dB, that would be a limit in that case. 00:44:25.929 --> 00:44:29.909 So read the footnotes carefully and there's details 00:44:29.909 --> 00:44:32.230 there and if you have a question about the footnote 00:44:32.230 --> 00:44:34.650 and don't... Totally understand what I'm trying 00:44:34.650 --> 00:44:39.230 to say. Send me an email, robettnc0b .com, robettnc0b 00:44:39.230 --> 00:44:44.690 .com. All right. Very good. Well, I know the 00:44:44.690 --> 00:44:48.420 phone lines are lit up and I I can't get the 00:44:48.420 --> 00:44:52.119 software to answer. So we're going to have to 00:44:52.119 --> 00:44:55.320 resort to Twitter here. So if you have something 00:44:55.320 --> 00:45:00.000 to ask, give us a tweet at ham talk live. And 00:45:00.000 --> 00:45:03.280 we are actually about out of time, but we'll 00:45:03.280 --> 00:45:06.000 see if we can get a couple of them in. But my 00:45:06.000 --> 00:45:09.860 apologies for for windows updates, slowing everything 00:45:09.860 --> 00:45:15.079 down here. Once again, the new computer is on 00:45:15.079 --> 00:45:19.010 the way, by the way. Rob, what were your thoughts 00:45:19.010 --> 00:45:24.289 from CQ Worldwide this weekend? Well, the conditions 00:45:24.289 --> 00:45:27.750 were an amazing surprise. I spent as much time 00:45:27.750 --> 00:45:32.010 on 15 as possible and then went to 20 when I 00:45:32.010 --> 00:45:34.849 had to and then went to 40 later, but 40 in the 00:45:34.849 --> 00:45:37.190 middle of the country here in Colorado with even 00:45:37.190 --> 00:45:40.730 a two element beam at 70 feet. trying to plow 00:45:40.730 --> 00:45:42.670 through to Europe with all the guys in the East 00:45:42.670 --> 00:45:46.030 Coast, a lot closer, kind of difficult, not so 00:45:46.030 --> 00:45:48.489 bad towards the Caribbean or South America. But 00:45:48.489 --> 00:45:52.449 I did keep running over to the 7610 set up on 00:45:52.449 --> 00:45:56.329 10 meters with an ACOM 1000. And actually, Sunday, 00:45:56.690 --> 00:45:59.389 the opening in the afternoon was amazing. Not 00:45:59.389 --> 00:46:01.710 that it was an amazing period. Two weeks before 00:46:01.710 --> 00:46:07.309 CQ Worldwide was a 10 -10 sprint QSO party. And 00:46:07.309 --> 00:46:10.639 I worked one station. in about 30 miles away. 00:46:11.500 --> 00:46:15.519 I normally work K8 DEL in Cincinnati. If I can't 00:46:15.519 --> 00:46:18.340 work Dell on 10 meters, the band's dead. And 00:46:18.340 --> 00:46:20.619 I did hear him a few times for a second or two 00:46:20.619 --> 00:46:23.800 here and there, maybe five seconds or 10 seconds 00:46:23.800 --> 00:46:27.460 at a time, but he didn't hear me. So I don't 00:46:27.460 --> 00:46:29.739 know what happened. Obviously we had some sunspots 00:46:29.739 --> 00:46:33.920 and 15 meters was just wall to wall and a lot 00:46:33.920 --> 00:46:38.590 of fun. So I'm sure the This the CQ worldwide 00:46:38.590 --> 00:46:40.670 CW coming up in November. They're going to hope 00:46:40.670 --> 00:46:42.889 for equally good propagation. Who knows what 00:46:42.889 --> 00:46:49.369 will happen Very good. Well, we're going to to 00:46:49.369 --> 00:46:53.809 finish up here, but Again, my apologies on the 00:46:53.809 --> 00:46:57.730 phones here, but it was out of our control. So 00:46:57.730 --> 00:47:02.710 a lot of great information and you know, there's 00:47:02.710 --> 00:47:07.280 just so many good radios out there and I look 00:47:07.280 --> 00:47:10.679 forward to hearing what you have to say about 00:47:10.679 --> 00:47:13.639 the 705 after you get a chance to play with it 00:47:13.639 --> 00:47:20.000 yourself a little bit. Obviously, there's been 00:47:20.000 --> 00:47:26.519 this big shift into direct sampling and I'm just 00:47:26.519 --> 00:47:32.260 amazed at how quiet they are. And from the ICOM 00:47:32.260 --> 00:47:34.219 standpoint, if you can run one of them, they 00:47:34.219 --> 00:47:36.500 all work the same way, whether it's the 7300, 00:47:36.699 --> 00:47:42.320 the 7610, the 9700, or I'm sure the 705. So that 00:47:42.320 --> 00:47:47.400 user interface is very consistent. If anyone 00:47:47.400 --> 00:47:50.679 would like to have a PDF copy of my most recent 00:47:50.679 --> 00:47:53.039 Zoom presentation, I believe it was to the Ham 00:47:53.039 --> 00:47:58.300 Radio Club in Austin, Texas, it includes a list 00:47:58.300 --> 00:48:03.070 of the top 18 transceivers, not the 18 counting 00:48:03.070 --> 00:48:05.409 down from my table because let me explain something 00:48:05.409 --> 00:48:10.050 here. There are more than one data point for 00:48:10.050 --> 00:48:13.670 like a K3 came out in 2008 and the K3 was updated 00:48:13.670 --> 00:48:15.989 with a new synthesizer and then the K3S came 00:48:15.989 --> 00:48:18.920 out. So it's there at least three times. The 00:48:18.920 --> 00:48:22.340 direct sampling radios have a little more variation 00:48:22.340 --> 00:48:25.159 in the way they test in the lab. Probably don't 00:48:25.159 --> 00:48:28.500 notice it on the air. But there's second samples 00:48:28.500 --> 00:48:32.119 on several of the direct sampling radios of all 00:48:32.119 --> 00:48:36.639 the brands. So I have this list that is the top 00:48:36.639 --> 00:48:40.900 110 down to 90. And believe me, a 90 dB radio 00:48:40.900 --> 00:48:44.840 is just fine. Clear up to 110. There's 18 different 00:48:44.840 --> 00:48:47.139 transceivers there that anyone should be happy 00:48:47.139 --> 00:48:50.400 using. Of course, the used market is now a bargain 00:48:50.400 --> 00:48:54.820 since the $7 ,300 is so inexpensive at $1 ,000. 00:48:55.219 --> 00:49:00.940 You can buy like a TS590S at maybe $600. So if 00:49:00.940 --> 00:49:04.760 you have a budget that doesn't go to the stratosphere, 00:49:05.119 --> 00:49:07.980 it's a buyer's market in the used market. And 00:49:07.980 --> 00:49:10.280 then even some of the new ones here at amazing 00:49:10.280 --> 00:49:14.079 prices. So if you would like to see a PDF, just 00:49:14.079 --> 00:49:17.449 send me a... Email at rob at nc0b .com and I'll 00:49:17.449 --> 00:49:20.010 send you a pdf of presentation. I just made a 00:49:20.010 --> 00:49:24.530 few weeks ago Very good rob. Well, thank you 00:49:24.530 --> 00:49:27.150 so much for being back on the show and I look 00:49:27.150 --> 00:49:30.230 forward to hearing more from you in the future 00:49:30.230 --> 00:49:35.389 and And we'll see what radios are out next. I 00:49:35.389 --> 00:49:39.489 know One you're you're really excited to see 00:49:39.489 --> 00:49:45.719 is the new k4 Right, do we have two minutes to 00:49:45.719 --> 00:49:47.559 talk about that? We got a couple of minutes. 00:49:47.559 --> 00:49:50.679 Go ahead. Okay. Well, we know the architecture. 00:49:51.619 --> 00:49:55.659 So a straight K4, we'll call it like half of 00:49:55.659 --> 00:49:59.619 a 7610. It's going to have one ADC and one set 00:49:59.619 --> 00:50:02.079 of bandpass filters, and you can get two receivers. 00:50:03.619 --> 00:50:05.480 But if you were actually wanted two receivers 00:50:05.480 --> 00:50:07.900 on two different bands, it would have to go broadband. 00:50:08.619 --> 00:50:12.900 The K4D would be like a 7610 as far as the architecture. 00:50:13.150 --> 00:50:17.170 two ADC chips, two sets of front -end LC filters, 00:50:18.030 --> 00:50:21.150 and of course then you could work 20 meters and 00:50:21.150 --> 00:50:24.250 15 if you're an SO2R guy, which I'm not, you 00:50:24.250 --> 00:50:26.789 could be listening on two bands and have full 00:50:26.789 --> 00:50:29.050 front -end filtering. Then of course we have 00:50:29.050 --> 00:50:31.130 the HD, which we have no idea what the price 00:50:31.130 --> 00:50:33.250 of that's going to be, and that would have like 00:50:33.250 --> 00:50:37.530 a K3S built into it, a SuperHat module with four 00:50:37.530 --> 00:50:40.570 roofing filters. That would be a sideband roofing 00:50:40.570 --> 00:50:43.250 filter, and a CW roofing filter for the main 00:50:43.250 --> 00:50:46.269 receiver, and one sideband roofing filter and 00:50:46.269 --> 00:50:49.010 one CW roofing filter for the second receiver, 00:50:49.170 --> 00:50:52.070 call it the sub receiver. So we know the architecture. 00:50:53.070 --> 00:50:56.190 I think we can kind of guess the numbers. I mean, 00:50:56.409 --> 00:50:59.570 all the direct sampling radios are more or less 00:50:59.570 --> 00:51:04.050 100 dB plus or minus a few. And then the K3S, 00:51:04.070 --> 00:51:07.670 for instance, is about 106 or 107. So I guess 00:51:07.670 --> 00:51:11.119 you'd have to assume the K4HD would be around 00:51:11.119 --> 00:51:14.599 that, maybe a couple DB higher, who knows. So 00:51:14.599 --> 00:51:18.639 we kind of have an idea on raw numbers. Of course, 00:51:18.880 --> 00:51:21.039 features, one thing that Ellicraft is saying 00:51:21.039 --> 00:51:23.980 that they will have someday is pre -distortion 00:51:23.980 --> 00:51:28.559 like Apache. And Flex has talked about pre -distortion 00:51:28.559 --> 00:51:33.079 for years. So it would be really good if two 00:51:33.079 --> 00:51:36.170 major OEMs in the US could offer the same thing 00:51:36.170 --> 00:51:39.090 for a super clean sideband signal that we currently 00:51:39.090 --> 00:51:44.269 only have from Apache. So of course, I'm anxious 00:51:44.269 --> 00:51:46.150 to get one through the lab. But at the moment, 00:51:46.210 --> 00:51:48.650 we're still all waiting for the K four. But I 00:51:48.650 --> 00:51:51.190 think we know it's it's approximate performance 00:51:51.190 --> 00:51:55.469 level. All right, well, we'll have to talk about 00:51:55.469 --> 00:52:00.039 that. at a later date when that's out as well 00:52:00.039 --> 00:52:04.099 as others out there on the market. So Rob, thank 00:52:04.099 --> 00:52:07.059 you so much for being here again and chatting 00:52:07.059 --> 00:52:11.480 with us tonight and appreciate all of your efforts 00:52:11.480 --> 00:52:15.760 and enjoy the retirement and we'll talk to you 00:52:15.760 --> 00:52:21.539 soon. 73, Neil, thank you. All right, well that's 00:52:21.539 --> 00:52:24.539 a wrap for this week's edition of HamTalk Live. 00:52:24.880 --> 00:52:28.659 Thanks to my guest, Rob Sherwood, NC0B and everybody 00:52:28.659 --> 00:52:32.179 out there in cyberspace for listening and typing 00:52:32.179 --> 00:52:34.900 in tonight and invite you back next Thursday 00:52:34.900 --> 00:52:38.139 night at 9 p .m.
