It's time for ham talk live episode 00:01:34.950 --> 00:01:41.290 number 237 Q &A with Rob Sherwood nc0b and the 00:01:41.290 --> 00:01:45.890 IC 705 recorded live on Thursday, November 19th 00:01:45.890 --> 00:01:49.969 2020 I'm your host Neil rap WB 9 VPG. Thanks 00:01:49.969 --> 00:01:54.290 for tuning in to this episode of ham talk live 00:01:54.290 --> 00:01:57.670 tonight. We're joined by Once again, by Rob Sherwood, 00:01:57.709 --> 00:02:00.969 NC0B. We'll take your calls in a few minutes. 00:02:01.670 --> 00:02:04.969 Last week, Marcel Steber, AI6MS, was here to 00:02:04.969 --> 00:02:08.210 talk about remote online license testing. If 00:02:08.210 --> 00:02:11.009 you missed that, you can listen anytime at HamTalkLive 00:02:11.009 --> 00:02:15.430 .com or on your favorite podcast app or on YouTube 00:02:15.430 --> 00:02:18.789 or you can catch the rebroadcast of this show. 00:02:19.129 --> 00:02:26.069 on WTWW out of Nashville, Tennessee. That's 5085 00:02:26.069 --> 00:02:32.370 AM, 5 .085 MHz, Saturday afternoons at about 00:02:32.370 --> 00:02:35.770 3 .30 PM Eastern Time. One quick announcement 00:02:35.770 --> 00:02:43.050 before we... Pay some bills here. HamSci is looking 00:02:43.050 --> 00:02:46.349 for volunteers to collect some eclipse data. 00:02:46.590 --> 00:02:49.389 Now if you haven't heard about the solar eclipse, 00:02:49.509 --> 00:02:52.509 that's because it's in South America this time. 00:02:53.189 --> 00:02:59.050 So they need some data on that as well as control 00:02:59.050 --> 00:03:03.849 data. So they're looking for people who can do 00:03:03.849 --> 00:03:10.259 some recording. Basically you hook a device up 00:03:10.259 --> 00:03:15.860 to your radio and record from December 9th through 00:03:15.860 --> 00:03:19.479 the 16th. And there's going to be a couple of 00:03:19.479 --> 00:03:23.680 practice runs on November 21st and December 5th. 00:03:23.680 --> 00:03:26.319 And they're trying to collect propagation data. 00:03:27.110 --> 00:03:30.009 when the next eclipse comes through, but again 00:03:30.009 --> 00:03:32.409 that won't be visible here in North America, 00:03:32.490 --> 00:03:36.330 it'll be down in South America. So if you can 00:03:36.330 --> 00:03:42.610 do that, if you can record some HF propagation 00:03:42.610 --> 00:03:48.229 for a week or so, go over to HamSci .org, that's 00:03:48.229 --> 00:03:54.289 H -A -M SCI .org and you can read more about 00:03:54.289 --> 00:03:57.710 it and sign up over there. So I'll be back with 00:03:57.710 --> 00:04:01.180 Rob. Right after this word from ICOM America, 00:04:01.539 --> 00:04:29.660 right here on HamTalk Live. This color display 00:04:29.660 --> 00:04:32.660 is 2 .3 inches for exceptional viewability and 00:04:32.660 --> 00:04:35.579 the audio is 80 % louder. This multifunction 00:04:35.579 --> 00:04:38.240 dual -band D -Star transceiver supports DR mode 00:04:38.240 --> 00:04:41.560 for easy access to local repeaters based on internal 00:04:41.560 --> 00:04:44.300 GPS information as well as terminal and access 00:04:44.300 --> 00:04:48.089 point modes. The ID52A also has Bluetooth for 00:04:48.089 --> 00:04:51.029 audio and data control, providing improved mobility 00:04:51.029 --> 00:04:54.029 and control. And for the first time in the amateur 00:04:54.029 --> 00:04:56.430 radio industry, you can now send photos from 00:04:56.430 --> 00:04:59.529 a connected Android device. Other features include 00:04:59.529 --> 00:05:01.709 wideband receiver with a guaranteed range of 00:05:01.709 --> 00:05:06.389 144 to 148 and 440 to 450 megahertz, VHF on both 00:05:06.389 --> 00:05:09.189 bands, UHF on both bands and one of each with 00:05:09.189 --> 00:05:12.329 the dual DV mode, integrated GPS with grid square 00:05:12.329 --> 00:05:16.060 locator, micro SD card slot. micro USB for data 00:05:16.060 --> 00:05:18.980 transfer programming and charge, and it's IPX7 00:05:18.980 --> 00:05:21.699 waterproof. The ID52A is the perfect companion 00:05:21.699 --> 00:05:25.240 to the IC705. Both use compatible batteries and 00:05:25.240 --> 00:05:27.560 headsets, and you can use the same Android app 00:05:27.560 --> 00:05:30.879 for D -Star operation. The IC705 is the perfect 00:05:30.879 --> 00:05:33.959 sidekick for hands that like to enjoy what both 00:05:33.959 --> 00:05:36.660 the great indoors and outdoors have to offer. 00:05:36.740 --> 00:05:39.019 It's the perfect QRP companion. Base station 00:05:39.019 --> 00:05:40.759 features and functionality at the tip of your 00:05:40.759 --> 00:05:44.250 fingers in a portable package covering HF, meters, 00:05:44.269 --> 00:05:46.709 2 meters and 70 centimeters.

WB9VPG. 00:06:43.620 --> 00:06:46.779 That's right, Delium 9 Bainte Pterodactyl Nat, 00:06:46.980 --> 00:06:50.360 right? You are listening to HamTalk Live with 00:06:50.360 --> 00:07:19.769 Neil Rapp, WB9VPG. Welcome back to HamTalk Live. 00:07:19.870 --> 00:07:22.470 Thanks to Icom America. Be sure to check out 00:07:22.470 --> 00:07:26.170 their website IcomAmerica .com slash amateur 00:07:26.170 --> 00:07:28.829 and those two new rigs we were talking about 00:07:28.829 --> 00:07:34.290 the IC705 and the ID52A and all of their gear 00:07:34.290 --> 00:07:39.000 over at Icom America. dot com slash amateur ham 00:07:39.000 --> 00:07:42.220 talk live comes your way every Thursday evening 00:07:42.220 --> 00:07:46.720 at 9 p .m. Eastern Time and that's Friday at 00:07:46.720 --> 00:07:52.300 zero 200 Zulu right now that we've got daylight 00:07:52.300 --> 00:07:57.720 savings time out of the way so tonight Rob Sherwood 00:07:57.720 --> 00:08:00.740 is back with us in see zero B he was here on 00:08:00.740 --> 00:08:05.860 episode 234 three weeks ago but Thanks to Windows 00:08:05.860 --> 00:08:10.899 Update, the phone lines were ringing but couldn't 00:08:10.899 --> 00:08:16.160 be answered. And so I started the laptop up instead 00:08:16.160 --> 00:08:19.660 of two hours early. I started it up like five 00:08:19.660 --> 00:08:24.639 hours early today. So we've got everything functioning 00:08:24.639 --> 00:08:27.519 or at least at the moment it is. We hope it stays 00:08:27.519 --> 00:08:31.100 that way. But immediately he said, you know, 00:08:31.230 --> 00:08:34.549 Why don't we do this again and and all we'll 00:08:34.549 --> 00:08:38.470 just do the the Q &A so We're going to do that 00:08:38.470 --> 00:08:41.549 tonight. He was gracious enough to come back 00:08:41.549 --> 00:08:45.669 and take your calls in 1974 Rob started Sherwood 00:08:45.669 --> 00:08:48.309 engineering offering Drake radio upgrades and 00:08:48.309 --> 00:08:52.370 started testing transceivers in 1976 and he's 00:08:52.370 --> 00:08:55.870 tested over a hundred now and that Data is all 00:08:55.870 --> 00:08:59.190 available at Sherwood engineering's website at 00:08:59.190 --> 00:09:07.129 sh er w e n g dot com or nc0b .com may be the 00:09:07.129 --> 00:09:10.870 the easier way to get that website up but rob 00:09:10.870 --> 00:09:14.169 thank you so much for coming back well my pleasure 00:09:14.169 --> 00:09:18.870 good afternoon to you or good evening yeah you 00:09:18.870 --> 00:09:21.590 know we had so much to talk about and we and 00:09:21.590 --> 00:09:25.269 we still went overtime even without the phones 00:09:25.269 --> 00:09:28.720 running So we're going to dedicate a lot of time 00:09:28.720 --> 00:09:33.899 to taking questions tonight. But in the meantime, 00:09:35.059 --> 00:09:39.539 you receive that IC 705 that you had just ordered 00:09:39.539 --> 00:09:43.659 a couple of days before the show. And so now 00:09:43.659 --> 00:09:50.179 you have your lab data on the IC 705. And I've 00:09:50.179 --> 00:09:52.220 seen some people talking about that and where 00:09:52.220 --> 00:09:56.720 it is and what that all means. And for full disclosure, 00:09:56.980 --> 00:10:01.080 ICOM is a sponsor of HamDoc Live. So we will 00:10:01.080 --> 00:10:04.940 say that. But when you were here, you were still 00:10:04.940 --> 00:10:08.419 waiting on it to arrive. But now that you've 00:10:08.419 --> 00:10:11.320 run it through the lab, what were your findings 00:10:11.320 --> 00:10:14.799 on it? Well, I was quite happy with it. And see, 00:10:14.860 --> 00:10:18.279 it's been up on my website since November 7th. 00:10:18.320 --> 00:10:20.799 My testing has continued. Matter of fact, the 00:10:20.799 --> 00:10:25.620 most recent update to the long form report several 00:10:25.620 --> 00:10:30.720 pages now you can download that at nc0b .com 00:10:30.720 --> 00:10:35.659 slash 705 no letters in there just nc0b .com 00:10:35.659 --> 00:10:41.120 slash 705 and I added the VHF UHF data that I 00:10:41.120 --> 00:10:43.559 didn't have right off the bat and then I added 00:10:43.559 --> 00:10:48.320 transmit composite noise this past weekend using 00:10:48.320 --> 00:10:52.950 the Perseus and down converting the signals from 00:10:52.950 --> 00:10:58.169 the VHF frequencies. So it really performs quite 00:10:58.169 --> 00:11:01.429 well and you consider it draws 200 mils approximately 00:11:01.429 --> 00:11:05.309 on receive in comparison to like a 7300 draws 00:11:05.309 --> 00:11:09.409 about an amp and the 7610 draws maybe three amps 00:11:09.409 --> 00:11:12.730 or something like that. So it's a lot in a small 00:11:12.730 --> 00:11:17.350 package for sure. Now there was some discussion 00:11:17.350 --> 00:11:20.470 about you know where this fell and comparison 00:11:20.470 --> 00:11:25.470 to the 7300 and 7610 and some of those others. 00:11:25.769 --> 00:11:27.690 And there was some discussion about, you know, 00:11:28.710 --> 00:11:31.190 well, you know, why is this a little further 00:11:31.190 --> 00:11:34.789 down? Is that enough to really make a difference 00:11:34.789 --> 00:11:38.710 or is that just the numbers? Well, it's still 00:11:38.710 --> 00:11:42.529 a big number. I mean, WAJI and I have said for 00:11:42.529 --> 00:11:45.990 decades, you know, your 80 dB radio is really 00:11:46.399 --> 00:11:49.000 Plenty good most of the time for most of us, 00:11:49.039 --> 00:11:51.419 you know, not every RF environment but one thing 00:11:51.419 --> 00:11:56.600 to notice if you really want to compare the 705 00:11:56.600 --> 00:12:02.200 to the 7300 or the 7610 for or even the 9700 00:12:02.200 --> 00:12:07.700 It the 705 does not have the feature called IP 00:12:07.700 --> 00:12:12.620 plus Which is a linearization feature of some 00:12:12.620 --> 00:12:16.159 ADC chips But I'm assuming that the chip in the 00:12:16.159 --> 00:12:19.200 705 is probably not the same one that's in the 00:12:19.200 --> 00:12:24.899 7300 due to current draw and all that. So it 00:12:24.899 --> 00:12:27.580 doesn't appear to have this built -in dither 00:12:27.580 --> 00:12:30.580 function, the linearization function. So if you 00:12:30.580 --> 00:12:34.279 want to compare the 705, I'd say look at the 00:12:34.279 --> 00:12:38.860 7300 or the 7610 with the dither turned off. 00:12:39.240 --> 00:12:41.779 And then you say, well, why do I want to do that? 00:12:42.159 --> 00:12:45.059 I have yet to have anyone, including myself, 00:12:45.500 --> 00:12:48.379 using the other two radios that have the IP Plus 00:12:48.379 --> 00:12:52.259 feature turn it on and off. I listen in some 00:12:52.259 --> 00:12:55.279 sort of a contest condition, and I don't really 00:12:55.279 --> 00:12:58.399 notice anything. Now, that doesn't mean that 00:12:58.399 --> 00:13:02.139 it never could make a difference. And on the 00:13:02.139 --> 00:13:05.120 lower frequencies, any kind of low -level distortion 00:13:05.120 --> 00:13:09.379 in these ADC radios, the digital radios, probably 00:13:09.379 --> 00:13:12.240 covered up by band noise. If you're in a quiet 00:13:12.240 --> 00:13:14.919 location on 10 and 12 meters or 6 meters, for 00:13:14.919 --> 00:13:18.539 instance, maybe theoretically, those distortion 00:13:18.539 --> 00:13:21.039 products that are covered up by bad noise on, 00:13:21.039 --> 00:13:25.519 you know, 40, 80, 160, maybe they'd be heard. 00:13:27.080 --> 00:13:30.500 So just don't get freaked out saying this number, 00:13:30.539 --> 00:13:35.759 it's only 88. Gee, 20 years ago, we wish we had 00:13:35.759 --> 00:13:38.620 an 88 dB radio. And then considering that most 00:13:38.620 --> 00:13:41.279 of us are going to be using it in a portable 00:13:41.279 --> 00:13:44.220 environment, at least part of the time. How many 00:13:44.220 --> 00:13:46.139 of us have a, you know, three element Yagi out 00:13:46.139 --> 00:13:49.240 in the park bench? So don't get too upset about 00:13:49.240 --> 00:13:56.360 it. Yeah, it's, it's, uh, I've had the same experience 00:13:56.360 --> 00:14:01.759 as you and we even tried the IP plus during field 00:14:01.759 --> 00:14:04.419 day. And we always said, well, you know, 7 ,300 00:14:04.419 --> 00:14:06.620 may not be the best radio to run during field 00:14:06.620 --> 00:14:11.470 day. because of other radios in the near vicinity. 00:14:11.909 --> 00:14:14.070 We used it and didn't have any trouble at all. 00:14:15.269 --> 00:14:18.029 And so we thought, well, let's just try the IP 00:14:18.029 --> 00:14:22.850 Plus just to see what it'll do. And I really 00:14:22.850 --> 00:14:26.830 could tell very, very little difference. And 00:14:26.830 --> 00:14:29.889 it actually worked just fine with the IP Plus 00:14:29.889 --> 00:14:32.570 on. Some people were having an issue with that. 00:14:33.919 --> 00:14:37.639 We didn't. I can't say that it's always going 00:14:37.639 --> 00:14:42.820 to be that way. I'm like you. I can't really 00:14:42.820 --> 00:14:45.659 tell a whole lot of difference at that level. 00:14:46.899 --> 00:14:50.000 Well now, do you happen to know how old that 00:14:50.000 --> 00:14:54.899 7300 was? Yeah, I don't know if it was before 00:14:54.899 --> 00:14:58.240 or after that change that you talked about last 00:14:58.240 --> 00:15:02.019 time. I need to look and see. if it was before 00:15:02.019 --> 00:15:04.820 or after that. I think it was before though. 00:15:05.840 --> 00:15:09.379 I mean, the first maybe 10 ,000 approximately, 00:15:09.440 --> 00:15:13.139 don't really know. It did raise the noise floor, 00:15:13.320 --> 00:15:17.120 which on 40 meters would matter not. 10 meters, 00:15:17.259 --> 00:15:20.960 yes. But if you don't need it on 10 meters, for 00:15:20.960 --> 00:15:24.279 instance, well then keep it off. Pretty simple. 00:15:24.379 --> 00:15:26.340 The other thing I want to comment is, you know, 00:15:26.480 --> 00:15:30.000 these numbers for an ADC direct sampling radio, 00:15:30.779 --> 00:15:34.600 are not exact because every chip is slightly 00:15:34.600 --> 00:15:38.000 different. And so you'll notice that their second 00:15:38.000 --> 00:15:44.759 sample for the 7300, for the 7610, and they're 00:15:44.759 --> 00:15:47.139 different by a modest, you know, some number 00:15:47.139 --> 00:15:51.960 of dB. So I don't have two copies of a 705, but 00:15:51.960 --> 00:15:55.960 these numbers are not as consistent as our old 00:15:55.960 --> 00:15:57.659 -fashioned, well, I shouldn't say old -fashioned, 00:15:58.000 --> 00:16:01.690 our legacy superhits. But, again, that's really 00:16:01.690 --> 00:16:05.570 kind of in the noise to make a pun. So the radio 00:16:05.570 --> 00:16:08.210 has features that I can't imagine I'll ever even 00:16:08.210 --> 00:16:11.529 learn to use. I mean, I saw this wonderful 20 00:16:11.529 --> 00:16:18.509 -minute YouTube by OH8STN, and he's doing digital 00:16:18.509 --> 00:16:21.070 things I didn't even know existed with his laptop 00:16:21.070 --> 00:16:24.879 out on a park bench or up on a mountain. The 00:16:24.879 --> 00:16:27.840 feature richness is amazing, plus it's all in 00:16:27.840 --> 00:16:33.299 one box. I just noticed on qth .com there was 00:16:33.299 --> 00:16:37.139 someone wanting to sell their KX3 and a PX3 and 00:16:37.139 --> 00:16:39.659 a microphone and all the cables because they 00:16:39.659 --> 00:16:44.080 want to have a 705. Well, you've got one box 00:16:44.080 --> 00:16:46.759 instead of multiple with all these interconnect 00:16:46.759 --> 00:16:51.600 things. So you can hook up your IC705 with one 00:16:51.600 --> 00:16:59.190 micro micro -USB connector on one end, the standard 00:16:59.190 --> 00:17:04.210 USB on the other end, and you're done. Yeah, 00:17:04.309 --> 00:17:10.210 it's nice for digital to have all that interfacing 00:17:10.210 --> 00:17:13.549 right there in the rig. That definitely helps. 00:17:14.109 --> 00:17:17.410 Any other things on the 705 before we move on 00:17:17.410 --> 00:17:21.609 to the questions? Well, let's just see what questions 00:17:21.609 --> 00:17:25.470 maybe the users have. Okay, all right. Well, 00:17:25.470 --> 00:17:27.190 we're going to take a little bit of an early 00:17:27.190 --> 00:17:30.950 break here But we want to give plenty of time 00:17:30.950 --> 00:17:34.150 for the call. So let me give you the phone number 00:17:34.150 --> 00:17:38.230 to call and And what'll happen is the system 00:17:38.230 --> 00:17:40.569 will put you in a queue So you'll be here and 00:17:40.569 --> 00:17:44.069 hold music just just keep holding there and it 00:17:44.069 --> 00:17:47.890 will Patch everybody through one at a time. It's 00:17:47.890 --> 00:17:55.869 eight five nine 9827373. So again, you can call 00:17:55.869 --> 00:17:59.589 that number in just a little bit and it'll just 00:17:59.589 --> 00:18:03.970 put you in line. So just hang on there and we'll 00:18:03.970 --> 00:18:07.230 get through as many questions as we can. And 00:18:07.230 --> 00:18:10.089 I saw another tweet just come through. So we've 00:18:10.089 --> 00:18:13.170 got a couple of those questions already. So we'll 00:18:13.170 --> 00:18:15.490 start addressing those when we come back. But 00:18:15.490 --> 00:18:23.079 again, the phone number. is 859 -982 -7373 and 00:18:23.079 --> 00:18:26.359 we'll give that out a few more times here after 00:18:26.359 --> 00:18:30.440 the break. So we'll come back with Rob and talk 00:18:30.440 --> 00:18:35.460 more about all these cool radios right after 00:18:35.460 --> 00:18:38.220 this word from Tower Electronics right here on 00:18:38.220 --> 00:18:40.579 HamTalk Live.

Now it's time for 00:21:55.140 --> 00:21:58.339 the HamTalk Live Ham Radio Joke of the Week, 00:21:58.559 --> 00:22:00.980 the part of the show where Rick tells us a ham 00:22:00.980 --> 00:22:04.200 radio joke. The HamTalk Live Ham Radio Joke of 00:22:04.200 --> 00:22:08.039 the Week is brought to you by QRM Labs. Now here's 00:22:08.039 --> 00:22:12.339 Rick Garrett in 9GSU with today's HamTalk Live 00:22:12.339 --> 00:22:19.759 Joke of the Week. I sat down to write a joke 00:22:19.759 --> 00:22:23.140 about QRM, but I was afraid it wouldn't be well 00:22:23.140 --> 00:22:27.579 received. This has been the HamTalk Live Ham 00:22:27.579 --> 00:22:31.539 Radio Joke of the Week with Rick Garrett in 9GSU. 00:22:31.880 --> 00:22:34.440 Tune in again next week for another joke from 00:22:34.440 --> 00:22:44.759 Rick. Well, there we go. Some QRM. Thank you 00:22:44.759 --> 00:22:48.900 Rick and we're back with Rob Sherwood NC0B and 00:22:48.900 --> 00:22:53.059 we're going to start taking your questions here 00:22:53.059 --> 00:22:57.640 and We'll do that by Twitter and we'll do that 00:22:57.640 --> 00:23:00.519 on the comments here on Spreaker if you're signed 00:23:00.519 --> 00:23:05.680 in to Spreaker and We'll also take phone calls. 00:23:05.680 --> 00:23:08.700 So it is time now for your phone call. So give 00:23:08.700 --> 00:23:11.299 us a call right now If you have a question for 00:23:11.299 --> 00:23:22.140 Rob at 859 -982 -7373. Again, 859 -982 -7373. 00:23:22.180 --> 00:23:28.720 Or if you'd rather type it, go to Twitter, hamtalklive 00:23:28.720 --> 00:23:31.500 on Twitter. And if you're listening to us on 00:23:31.500 --> 00:23:34.279 WTWW or on the podcast edition, you won't be 00:23:34.279 --> 00:23:36.400 able to reach us because we're doing this on 00:23:36.400 --> 00:23:40.460 Thursday night. Just a heads up there. We've 00:23:40.460 --> 00:23:44.099 got one from from Germany coming in here. So 00:23:44.099 --> 00:23:49.819 we'll get to that in a minute, but first Brett, 00:23:49.819 --> 00:23:52.299 WI7BG, has a question for you, Rob. He says, 00:23:52.660 --> 00:23:55.079 based on your tests, and let me make sure, yeah, 00:23:55.160 --> 00:23:58.279 I got your mic back on here. Based on your tests, 00:23:58.440 --> 00:24:01.579 what features do you think are most important 00:24:01.579 --> 00:24:05.059 in a state -of -the -art radio? Is it the number 00:24:05.059 --> 00:24:08.460 of bits in the ADC? Is it SuperHat versus direct 00:24:08.460 --> 00:24:12.059 conversion? Is it roofing filters or something 00:24:12.059 --> 00:24:16.019 completely different? OK, well, there's a lot 00:24:16.019 --> 00:24:18.700 of questions there. So first off, I'll say on 00:24:18.700 --> 00:24:23.019 bits, whether it's a 14 -bit or 16 -bit matters 00:24:23.019 --> 00:24:27.480 not. ADCs have noise. Now, if there was no such 00:24:27.480 --> 00:24:29.460 thing as noise, then it would make a difference. 00:24:30.059 --> 00:24:33.380 But if you do the math, the difference in dynamic 00:24:33.380 --> 00:24:37.119 range of a 14 -bit versus 16 -bit is a fraction 00:24:37.119 --> 00:24:41.460 of a dB. So that's in the noise. Well, you mentioned 00:24:41.460 --> 00:24:46.039 direct sampling and direct conversion and super 00:24:46.039 --> 00:24:48.119 hits. So those are all different ways to come 00:24:48.119 --> 00:24:50.440 up with the same thing. We want RF in and audio 00:24:50.440 --> 00:24:55.359 out in a very difficult RF environment like field 00:24:55.359 --> 00:24:58.539 day, where you have multiple stations on the 00:24:58.539 --> 00:25:02.640 same band. Well, then the super hit with a roofing 00:25:02.640 --> 00:25:05.599 filter will have an advantage, maybe as much 00:25:05.599 --> 00:25:09.000 as 25 dB from an overload standpoint, because 00:25:09.680 --> 00:25:12.880 The direct sampling radio is going to see at 00:25:12.880 --> 00:25:16.059 least the entire band, if not a half -octave. 00:25:16.059 --> 00:25:20.619 For instance, on 20 meters, a typical radio will 00:25:20.619 --> 00:25:23.299 have a half -octave filter that might be about 00:25:23.299 --> 00:25:27.779 11 MHz to 15 MHz. So all that signal that's coming 00:25:27.779 --> 00:25:31.140 in from the antenna is going to be impinging 00:25:31.140 --> 00:25:37.630 on the ADC chip. legacy radio with a roofing 00:25:37.630 --> 00:25:40.009 filter, even if it was an older radio that had 00:25:40.009 --> 00:25:43.670 a 15kc roofing filter as opposed to like a K3 00:25:43.670 --> 00:25:48.309 with a 2 .8 or 500 Hertz, the roofing filter 00:25:48.309 --> 00:25:50.230 is going to get rid of most of the signals before 00:25:50.230 --> 00:25:54.650 it goes downstream. Now the KX3 for instance, 00:25:54.950 --> 00:25:58.829 or the KX2, is a direct conversion. That means 00:25:58.829 --> 00:26:02.509 it goes right to baseband audio. the direct sampling 00:26:02.509 --> 00:26:07.750 doesn't really have an IF per se. So that of 00:26:07.750 --> 00:26:11.309 course goes right in from the ADC into the FPGA, 00:26:11.410 --> 00:26:17.710 the field programmable logic array. So you really 00:26:17.710 --> 00:26:20.089 just sort of need to decide what's my environment 00:26:20.089 --> 00:26:22.490 today. If you're at your home and you don't have 00:26:22.490 --> 00:26:25.230 a ham that's 10 blocks away or maybe even a mile 00:26:25.230 --> 00:26:28.109 or two away. you're probably never going to be 00:26:28.109 --> 00:26:29.769 worried about it one way or the other. But if 00:26:29.769 --> 00:26:33.329 you do have a ham really close by, or maybe a 00:26:33.329 --> 00:26:35.130 broadcast station, which hopefully you could 00:26:35.130 --> 00:26:38.670 get rid of with an external filter, there are 00:26:38.670 --> 00:26:43.750 times when the hybrid Kenwood or the hybrid New 00:26:43.750 --> 00:26:46.089 Yezu, both of those two, they're a super hit 00:26:46.089 --> 00:26:48.630 with roofing filters. So sometimes that's better. 00:26:51.329 --> 00:26:56.359 So it really does make a difference as to you 00:26:56.359 --> 00:26:58.900 know, what your operating environment is, and 00:26:58.900 --> 00:27:01.599 so that's some good information. Well, thank 00:27:01.599 --> 00:27:05.619 you for that. Let me drop in one thing pretty 00:27:05.619 --> 00:27:08.700 quickly here. Once I finished the first day in 00:27:08.700 --> 00:27:11.440 the lab when I got most of the HF data on the 00:27:11.440 --> 00:27:17.319 705, I then hooked it up to my high -gain 204BA. 00:27:17.940 --> 00:27:23.480 An antenna has been up there since 1972. and 00:27:23.480 --> 00:27:26.319 talk to my friend in Alaska, KL7QOW. I talked 00:27:26.319 --> 00:27:29.539 to him for 20 minutes. He was running a kilowatt 00:27:29.539 --> 00:27:32.240 with a Yagi at 105 feet, and I was running 10 00:27:32.240 --> 00:27:35.200 watts with a Yagi at 50 feet. And we had a great 00:27:35.200 --> 00:27:40.039 time. So that was fun. Yeah, that's always fun. 00:27:41.259 --> 00:27:45.019 Well, we've got another question here from Germany 00:27:45.019 --> 00:27:49.720 from Ed, DD5LP. And we've got a lot here and 00:27:49.720 --> 00:27:52.200 actually sent you this one early so you could 00:27:53.069 --> 00:27:56.390 have it in front of you here. So while not directly 00:27:56.390 --> 00:27:59.369 related to measurement of performance, I'm sure 00:27:59.369 --> 00:28:02.170 Rob has an understanding of the internal design 00:28:02.170 --> 00:28:05.829 of the IC705 and may have an answer for this. 00:28:05.930 --> 00:28:09.549 Does the IC705, like many other ICOM transceivers, 00:28:09.849 --> 00:28:14.730 have links or diodes that can be removed to wideband 00:28:14.730 --> 00:28:17.529 or extend the frequency coverage on transmit 00:28:17.529 --> 00:28:21.329 as well as receive of the transceiver? The background 00:28:21.329 --> 00:28:25.430 of this question is that ICOM UK and I believe 00:28:25.430 --> 00:28:29.390 ICOM Europe originally stated that the IC 705 00:28:29.390 --> 00:28:33.730 would cover HF 6 meters 4 meters 2 meters and 00:28:33.730 --> 00:28:36.890 70 centimeters in the IC 705 model for Europe 00:28:36.890 --> 00:28:40.190 but later removed the European 4 meter which 00:28:40.190 --> 00:28:44.750 is 70 to 70 and a half megahertz band from the 00:28:44.750 --> 00:28:48.009 specifications the European model the IC 7300 00:28:48.599 --> 00:28:51.279 does cover four meters and so it would make sense 00:28:51.279 --> 00:28:55.880 that the 705 would also have that coverage. If 00:28:55.880 --> 00:29:00.640 it's a case of ICOM Europe and ICOM UK deciding 00:29:00.640 --> 00:29:03.559 that they didn't want to have the extra support 00:29:03.559 --> 00:29:07.200 cost and possibly production cost from the factory 00:29:07.200 --> 00:29:09.920 to support four meters that's one possible reason 00:29:09.920 --> 00:29:13.559 but you want to know Rob if you can see a technical 00:29:13.559 --> 00:29:17.599 reason with the HF SDR and down converter configuration 00:29:18.599 --> 00:29:22.259 Why 70 to 70 and a half megahertz would technically 00:29:22.259 --> 00:29:27.599 not be possible He goes on to say if it's a case 00:29:27.599 --> 00:29:29.519 of icon believing the option of the customer 00:29:29.519 --> 00:29:32.180 to wideband the rig at their own risk Would that 00:29:32.180 --> 00:29:35.220 also mean in the u .s. The 220 megahertz band 00:29:35.220 --> 00:29:38.799 would also be covered They don't have that over 00:29:38.799 --> 00:29:41.420 in Europe because they use that for digital radio 00:29:41.420 --> 00:29:47.059 broadcast. So So basically it comes down to four 00:29:47.059 --> 00:29:53.759 meters What why are some of these? capable and 00:29:53.759 --> 00:29:57.880 some not Okay. Well, I'm glad you gave me that 00:29:57.880 --> 00:30:00.099 question a few days ago. So I did spend about 00:30:00.099 --> 00:30:02.839 an hour or more researching it and yes, there's 00:30:02.839 --> 00:30:07.259 a diode bank and yes, there's people who've Broadbanded 00:30:07.259 --> 00:30:10.579 it to an extent certainly in the HF range. So 00:30:11.140 --> 00:30:13.700 people were interested in 60 meters and that 00:30:13.700 --> 00:30:15.740 appears to work and then I guess if you want 00:30:15.740 --> 00:30:18.160 to be dumb enough to try to transmit on the citizens 00:30:18.160 --> 00:30:20.859 band you could probably make it do that too with 00:30:20.859 --> 00:30:23.980 a couple more diodes out and it did broadband 00:30:23.980 --> 00:30:28.099 on HF but it looked like it was going to broadband 00:30:28.099 --> 00:30:31.339 on four meters because the when you transmit 00:30:31.339 --> 00:30:34.140 and you've got the waterfall and the spectrum 00:30:34.140 --> 00:30:36.400 scope working when you talk you know that's there 00:30:36.400 --> 00:30:41.009 but there wasn't any output so I don't know the 00:30:41.009 --> 00:30:44.490 answer to why it's not there, but it could be 00:30:44.490 --> 00:30:46.569 that even though they took the diode out that 00:30:46.569 --> 00:30:48.650 maybe would have provided that, it's possible 00:30:48.650 --> 00:30:52.170 that the low -pass filter that's in the rig to 00:30:52.170 --> 00:31:00.210 deal with six meters in the harmonics, it wouldn't 00:31:00.210 --> 00:31:04.609 pass the 70 megahertz. I mean, that's just a 00:31:04.609 --> 00:31:08.210 speculation. I don't know. I don't know, in the 00:31:08.210 --> 00:31:10.150 other rigs, maybe the ones that do cover four 00:31:10.150 --> 00:31:13.430 meters, they change the low pass filter that 00:31:13.430 --> 00:31:15.869 would be just for six meters and change it so 00:31:15.869 --> 00:31:20.230 it works for six and four. And so why they made 00:31:20.230 --> 00:31:21.910 that decision, I don't know, but it appears at 00:31:21.910 --> 00:31:24.809 the moment they, no luck on that. As far as 220, 00:31:25.670 --> 00:31:27.410 nothing, I found nothing on the internet about 00:31:27.410 --> 00:31:29.869 that whatsoever. So I'd say that's probably zero 00:31:29.869 --> 00:31:33.630 chance. Okay, very good. Well, thank you, Ed, 00:31:33.750 --> 00:31:36.809 for sending that along and sending it early so 00:31:36.809 --> 00:31:40.029 we could get that in there. Alright, again, phone 00:31:40.029 --> 00:31:45.829 number 859 -982 -7373 if you have a question 00:31:45.829 --> 00:31:50.930 for Rob Sherwood, NC0B about receiver performance 00:31:50.930 --> 00:31:54.309 and radio performance. Give us a call right now. 00:31:54.670 --> 00:32:01.710 Again, 859 -982 -7373. We've got another one 00:32:01.710 --> 00:32:09.309 here that's asking about the 7610 and the 590. 00:32:11.289 --> 00:32:16.269 Any comparisons between those? Well, you know, 00:32:16.329 --> 00:32:22.369 for a long time, the 590S and the 590SG were 00:32:22.369 --> 00:32:26.130 the best bang for the buck. They were a fine 00:32:26.130 --> 00:32:30.069 transceiver. They had some unusual heteronide 00:32:30.069 --> 00:32:32.670 methods because it was a down conversion radio, 00:32:32.750 --> 00:32:35.690 a low IF version on most of the bands, except 00:32:35.690 --> 00:32:39.930 for the work bands, 10 meters and 6 meters. So 00:32:39.930 --> 00:32:44.970 from maybe a CWF contest standpoint, it didn't 00:32:44.970 --> 00:32:48.930 perform as well on 6 meters as, for instance, 00:32:48.970 --> 00:32:52.410 an Eagle, which didn't have the unusual difference 00:32:52.410 --> 00:32:57.230 in the way the mixing worked. Then the 7300 came 00:32:57.230 --> 00:33:00.789 along and suddenly became the bang for the buck 00:33:00.789 --> 00:33:03.930 leader due to features, if nothing else. I mean, 00:33:04.009 --> 00:33:07.630 you've got the band scope, you've got more adjustability 00:33:07.630 --> 00:33:12.809 on bandwidth, and the noise reduction was really 00:33:12.809 --> 00:33:16.049 good. And then you jump up clear to the 7610, 00:33:16.069 --> 00:33:18.269 my goodness. Well, then you've got dual receivers. 00:33:18.569 --> 00:33:22.940 You've got solid state TR switching for no noise 00:33:22.940 --> 00:33:25.660 acoustically and you have the ability to key 00:33:25.660 --> 00:33:28.640 an amplifier with a FET instead of a relay although 00:33:28.640 --> 00:33:32.599 you can do both on a 7610 you cannot on the 7300 00:33:32.599 --> 00:33:35.180 you've got two relays making clicking noises 00:33:35.180 --> 00:33:39.079 with a 7300 and the 7610 has an audio peak filter 00:33:39.079 --> 00:33:43.039 I honestly don't remember I'm afraid to say whether 00:33:43.039 --> 00:33:45.779 the 590 has an audio peak filter you can probably 00:33:45.779 --> 00:33:47.839 figure that out fairly quickly with a quick web 00:33:47.839 --> 00:33:51.920 search so I mean the 590 and the 7610 are very 00:33:51.920 --> 00:33:55.660 different. Now if I was on field day and we've 00:33:55.660 --> 00:33:59.640 got a CW station and a FTH station and a sideband 00:33:59.640 --> 00:34:02.559 station on the same band, I might well pick the 00:34:02.559 --> 00:34:05.259 590 simply because it's the roofing filter type 00:34:05.259 --> 00:34:08.980 radio and would be bothered less by that other 00:34:08.980 --> 00:34:11.699 station that might be the antenna might be a 00:34:11.699 --> 00:34:18.119 hundred feet away. Okay, well that sounds like 00:34:18.119 --> 00:34:22.949 a Good answer and again comes back to environment, 00:34:23.650 --> 00:34:29.530 which seems to be a theme here tonight. 859 -982 00:34:29.530 --> 00:34:32.949 -7373 is the phone number. Give us a call. Phone 00:34:32.949 --> 00:34:35.909 lines are open and we'll take your calls and 00:34:35.909 --> 00:34:39.690 questions here. You can also tweet us at HamTalk 00:34:39.690 --> 00:34:48.340 Live. Just a quick thing here. Troy, who is normally 00:34:48.340 --> 00:34:52.260 a faithful listener live, is celebrating his 00:34:52.260 --> 00:34:57.119 birthday today. So happy birthday to Troy. 859 00:34:57.119 --> 00:35:03.619 -982 -7373 is the number. Rob, what else are 00:35:03.619 --> 00:35:09.119 you seeing? I'm a little curious about sweepstakes 00:35:09.119 --> 00:35:12.989 this weekend. What are you going to run? Well, 00:35:12.989 --> 00:35:16.730 I will be running the IC705. It will not be barefoot. 00:35:17.210 --> 00:35:20.510 That would, of course, be a category. But I've 00:35:20.510 --> 00:35:24.510 been using the 705 two different ways besides 00:35:24.510 --> 00:35:28.570 barefoot. In Denver, I just drove my Alpha 99 00:35:28.570 --> 00:35:31.489 and it put out about 200 watts. And so I just 00:35:31.489 --> 00:35:33.610 had a couple of rag chews that way just to see 00:35:33.610 --> 00:35:35.269 if that all worked. And it was a piece of cake. 00:35:35.309 --> 00:35:40.949 I just needed a key line. So that was easy. Because 00:35:40.949 --> 00:35:44.610 I am going to be running the 705 in a double 00:35:44.610 --> 00:35:50.090 rail 160 CW first weekend of December and the 00:35:50.090 --> 00:35:52.949 a double rail 10 meter contest the second weekend 00:35:52.949 --> 00:35:55.889 of December I thought I need a dry run. I need 00:35:55.889 --> 00:36:00.710 to be sure n1 mm plus is working So I'll be running 00:36:00.710 --> 00:36:04.309 sweepstakes to as a test. I'm not going to be 00:36:04.309 --> 00:36:08.159 trying to really compete But here's how the setup 00:36:08.159 --> 00:36:10.079 will be for that. And this is just a choice, 00:36:10.119 --> 00:36:12.900 of course. I could easily drive the Alpha up 00:36:12.900 --> 00:36:16.000 there at the contest station with the 10 watts, 00:36:16.039 --> 00:36:18.059 and I'd get out a couple hundred watts. That 00:36:18.059 --> 00:36:20.199 would be fine. And I'd be in the, or maybe back 00:36:20.199 --> 00:36:23.199 it off to 150 watts to be in the low power category. 00:36:23.900 --> 00:36:27.099 But I have an intermediate amplifier from Ten 00:36:27.099 --> 00:36:29.159 Tech, and you could have one from Aldercraft, 00:36:29.219 --> 00:36:35.760 for instance, the KXPA100. So I take the... 705 00:36:35.760 --> 00:36:38.500 and turn it down to a watt and a half drive the 00:36:38.500 --> 00:36:40.400 little intermediate amp which then drives the 00:36:40.400 --> 00:36:43.420 big amp So I'll play with sweepstakes. I may 00:36:43.420 --> 00:36:46.760 do it both ways. I may try it with the Full power 00:36:46.760 --> 00:36:49.059 and then I may just turn off the intermediate 00:36:49.059 --> 00:36:51.380 amp and just run a hundred hundred watts or 150 00:36:51.380 --> 00:36:54.820 watts So that's what I plan to do this weekend 00:36:54.820 --> 00:36:58.820 Alright sounds like a good good way to check 00:36:58.820 --> 00:37:02.610 everything out and I know you like to You're 00:37:02.610 --> 00:37:05.269 the expert with all these numbers, but yet when 00:37:05.269 --> 00:37:08.369 these numbers are so good on so many radios, 00:37:08.769 --> 00:37:13.130 you really like to get in there and run a few 00:37:13.130 --> 00:37:17.289 contests with it before you give your final say 00:37:17.289 --> 00:37:22.489 -so about these rigs. Well, one thing is if you 00:37:22.489 --> 00:37:25.690 are used to the ICOM direct sampling radios, 00:37:26.010 --> 00:37:29.550 there's almost no learning curve from an HF standpoint 00:37:29.550 --> 00:37:33.730 or even two meter sideband for instance. It just 00:37:33.730 --> 00:37:37.269 works the same way. So you're not trying to pull 00:37:37.269 --> 00:37:39.329 out the manual to figure out how to change the 00:37:39.329 --> 00:37:42.130 span on the band scope or whatever. So that's 00:37:42.130 --> 00:37:47.150 really easy since I have a 7300 and a 7610. So 00:37:47.150 --> 00:37:51.170 it makes the 705 just a slightly different box. 00:37:51.750 --> 00:37:54.829 Now if we were talking about all these exotic 00:37:54.829 --> 00:37:58.329 digital things or d star well then that i don't 00:37:58.329 --> 00:38:00.510 happen to play in those world but boy a lot of 00:38:00.510 --> 00:38:05.190 people will yeah there's a lot of different modes 00:38:05.190 --> 00:38:08.590 for a lot of different folks and it's nice to 00:38:08.590 --> 00:38:11.949 be able to to have some versatility you know 00:38:11.949 --> 00:38:15.389 let's uh one thing let me remind people real 00:38:15.389 --> 00:38:19.650 quick 859 -982 -7373 because we're going to uh 00:38:19.650 --> 00:38:22.110 to finish up here before too long okay robert 00:38:22.110 --> 00:38:27.429 go ahead So I find I like leaving the multifunction 00:38:27.429 --> 00:38:31.090 knob on RIT So it's very easy to adjust that 00:38:31.090 --> 00:38:32.949 if you're in a roundtable and if you are picky 00:38:32.949 --> 00:38:35.630 on tuning in on frequency which I certainly am 00:38:35.630 --> 00:38:40.929 so the usability is really good and that's how 00:38:40.929 --> 00:38:46.150 I talked to my weekly schedules and In this case, 00:38:46.289 --> 00:38:49.250 if they're scattered around 10, 20, 30 Hz frequency, 00:38:49.789 --> 00:38:52.590 just turn that little knob. A lot of nice features 00:38:52.590 --> 00:38:58.269 there. Yeah, it's always great to have that little 00:38:58.269 --> 00:39:04.210 knob. It's always nice to be able to tune that 00:39:04.210 --> 00:39:10.949 right in. I don't know. There's just something 00:39:10.949 --> 00:39:14.489 there about having having .00 exactly on the 00:39:14.489 --> 00:39:18.050 end, too. I don't know what that is, but it really 00:39:18.050 --> 00:39:20.070 doesn't matter. But it feels so much better. 00:39:20.170 --> 00:39:25.710 I don't know. Well, I think we're through everything 00:39:25.710 --> 00:39:29.710 here that we have tonight, Rob. So so we'll finish 00:39:29.710 --> 00:39:32.550 up here. But thanks so much for coming on and 00:39:32.550 --> 00:39:36.840 for researching all the. Answers to the questions 00:39:36.840 --> 00:39:39.659 that have come in here and and answering those 00:39:39.659 --> 00:39:44.380 on the spot as well and Look forward to to hearing 00:39:44.380 --> 00:39:47.920 your comments after after you've had a chance 00:39:47.920 --> 00:39:53.880 to to really give the 705 a run on a couple of 00:39:53.880 --> 00:39:57.840 contests and and see What your thoughts are but 00:39:57.840 --> 00:40:02.000 it sounds like you know another great option 00:40:02.000 --> 00:40:05.659 Let me make it sort of generalization comment. 00:40:05.800 --> 00:40:10.400 I did expand my 18 radio list the other day for 00:40:10.400 --> 00:40:18.320 a new presentation. And that list, which I have 00:40:18.320 --> 00:40:23.300 given at several either live or Zoom type presentations, 00:40:24.059 --> 00:40:28.380 is the top 18 and now the top 20 individual transceivers, 00:40:28.699 --> 00:40:32.260 not second samples like I may have mentioned 00:40:32.260 --> 00:40:34.119 three weeks ago, you know, like there's several 00:40:34.119 --> 00:40:36.239 up there for the K3 because it went through different 00:40:36.239 --> 00:40:38.159 iterations and they were all slightly different. 00:40:38.599 --> 00:40:41.139 And then the fact we have second samples, two 00:40:41.139 --> 00:40:43.300 samples of several of the direct sampling radios. 00:40:43.960 --> 00:40:47.960 So if you just simplify it, so we just have individual 00:40:47.960 --> 00:40:50.880 models. And I took out the receivers. There's 00:40:50.880 --> 00:40:53.139 a couple of receivers and so they're not transceivers. 00:40:54.019 --> 00:40:56.599 So anyway, I tried to decided to expand the group 00:40:56.599 --> 00:41:01.570 from 18 to 20. And the 705 is number 20. And 00:41:01.570 --> 00:41:07.269 so in all of those, you can be very happy that 00:41:07.269 --> 00:41:10.650 you can work a lot of DX in a contest or whatever 00:41:10.650 --> 00:41:13.130 besides just rag chewing, which is not usually 00:41:13.130 --> 00:41:16.730 a stressful environment. N2IC is a big contester. 00:41:17.030 --> 00:41:21.389 He used the Para 590s. Antennas are really important, 00:41:21.710 --> 00:41:25.590 so you don't have to buy them. $5 ,000 radio 00:41:25.590 --> 00:41:27.750 necessarily. And certainly, if you're a new ham, 00:41:27.869 --> 00:41:30.130 I'd never recommend a new ham to go spend a fortune. 00:41:31.250 --> 00:41:34.070 Spend something in the $1 ,000 range, plus or 00:41:34.070 --> 00:41:36.909 minus, that fits your budget. And then find out 00:41:36.909 --> 00:41:38.889 what this wonderful hobby is, and hopefully you'll 00:41:38.889 --> 00:41:41.349 be doing it for the next 50 years like I am. 00:41:41.710 --> 00:41:45.710 I think I'm licensed in 1961, so a long time 00:41:45.710 --> 00:41:50.650 ago. one radio and if you look at my chart some 00:41:50.650 --> 00:41:53.090 people say well gee i gotta buy the top two or 00:41:53.090 --> 00:41:55.030 three well that's silliness there's just so many 00:41:55.030 --> 00:41:58.570 choices a day over a wide price range you can 00:41:58.570 --> 00:42:00.590 enjoy the hobby with a lot of different products 00:42:00.590 --> 00:42:03.289 and any brand you really are connected with if 00:42:03.289 --> 00:42:06.449 you've been a yezu owner for years you've been 00:42:06.449 --> 00:42:12.190 a kenwood owner icon whatever and so You can 00:42:12.190 --> 00:42:14.269 stay with a given brand or you can take something 00:42:14.269 --> 00:42:17.630 new. But the range of performance for the dollar 00:42:17.630 --> 00:42:23.010 is unprecedented today. Yeah. And I think that's 00:42:23.010 --> 00:42:26.170 something to keep in mind with the 705 because 00:42:26.170 --> 00:42:28.210 some people were saying, well, you know, it's, 00:42:28.210 --> 00:42:33.110 it's way down the list. Well, you know, does 00:42:33.110 --> 00:42:41.489 it really matter? I would. That's the thing. 00:42:42.230 --> 00:42:44.769 You don't buy a radio on one number. I don't 00:42:44.769 --> 00:42:48.590 care what your budget is and how exotic your 00:42:48.590 --> 00:42:53.449 setup is.
