Good evening everyone. It's time for HamTalk 00:01:38.640 --> 00:01:43.659 Live episode number 101. The science learned 00:01:43.659 --> 00:01:47.439 from the solar eclipse QSO party recorded live 00:01:47.439 --> 00:01:52.219 on Thursday, February 8th, 2018. I'm your host, 00:01:52.319 --> 00:01:55.920 Neil Rapp, WB9VPG. Thanks for tuning into this 00:01:55.920 --> 00:01:59.819 episode of HamTalk Live. Tonight we're joined 00:01:59.819 --> 00:02:04.989 by Dr. Nathaniel Frisell, W2NAF. and we'll take 00:02:04.989 --> 00:02:09.169 your calls live in just a few minutes. Last week 00:02:09.169 --> 00:02:13.810 Val in V9L and Bryant KG5HVO were here to give 00:02:13.810 --> 00:02:18.110 us a live update on the Bouvet Island De -Expedition 00:02:18.110 --> 00:02:22.229 and since that show they did have to cancel that 00:02:22.229 --> 00:02:24.590 trip due to some engine problems on the boat 00:02:24.590 --> 00:02:29.370 and we wish them a safe journey home. They're 00:02:29.370 --> 00:02:34.009 trying to get to South Africa right now and on 00:02:34.009 --> 00:02:38.409 one engine and they're already talking about 00:02:38.409 --> 00:02:41.509 rescheduling so we'll try to catch up with them 00:02:41.509 --> 00:02:44.090 at some point. If you missed that show you can 00:02:44.090 --> 00:02:47.750 listen anytime at HamTalkLive .com or you can 00:02:47.750 --> 00:02:50.610 tune in on one of those podcast outlets like 00:02:50.610 --> 00:02:54.069 Apple Podcasts or Stitcher or I Heart Podcasts. 00:02:54.030 --> 00:02:57.270 Google Play, TuneIn, or SoundCloud.

It's Monday through Friday on 00:03:12.129 --> 00:03:16.590 most bands and all modes. And more information 00:03:16.590 --> 00:03:23.740 is at arrl .org. school -club -roundup. So I 00:03:23.740 --> 00:03:26.860 know I'll be on the air every day next week. 00:03:27.479 --> 00:03:31.500 So hope to hear you as my students are on and 00:03:31.500 --> 00:03:35.919 all these other students around the globe getting 00:03:35.919 --> 00:03:40.219 on and trying to talk to each other and everyone 00:03:40.219 --> 00:03:44.479 else. So be sure to get on. Also, it's time for 00:03:44.479 --> 00:03:47.680 nominations for the Young Ham Linza Hand Award. 00:03:48.139 --> 00:03:51.379 Carol Perry, WB2MGP, will be collecting nominations 00:03:51.379 --> 00:03:56.539 to recognize a young licensed person, age 19 00:03:56.539 --> 00:03:59.280 or younger, who has gone above and beyond to 00:03:59.280 --> 00:04:02.500 help others. Maybe it's helping with an antenna 00:04:02.500 --> 00:04:06.000 installation, showing ham radio to others. Helping 00:04:06.000 --> 00:04:08.060 with emergency communications or maybe it's not 00:04:08.060 --> 00:04:11.539 even necessarily ham radio related, but they're 00:04:11.539 --> 00:04:15.000 licensed ham The winner will receive an award 00:04:15.000 --> 00:04:19.079 from the Radio Club of America their youth activities 00:04:19.079 --> 00:04:21.439 directive at the Dayton hamvention youth forum 00:04:21.439 --> 00:04:25.199 and a $100 stipend donated by the quarter century 00:04:25.199 --> 00:04:27.860 Wireless Association for their good deeds.

Well, our guest tonight 00:07:39.740 --> 00:07:44.040 is Dr. Nathaniel Frisell, W2NAF. He is an assistant 00:07:44.040 --> 00:07:47.240 research professor at the New Jersey Institute 00:07:47.240 --> 00:07:51.560 of Technology Center for Solar Terrestrial Research. 00:07:51.899 --> 00:07:56.180 he's the lead organizer of HamSci, a project 00:07:56.180 --> 00:07:58.920 that explores how ham radio can help us understand 00:07:58.920 --> 00:08:03.019 more about the physics of the ionosphere. Nathaniel 00:08:03.019 --> 00:08:05.639 completed his PhD in electrical engineering in 00:08:05.639 --> 00:08:10.860 spring 2016 at the Superdarn HF Radar Laboratory 00:08:10.860 --> 00:08:15.019 at Virginia Tech. He was also involved in the 00:08:15.019 --> 00:08:17.740 Virginia Tech Amateur Radio Association where 00:08:17.740 --> 00:08:20.379 he coordinated the VE team. His interests include 00:08:20.379 --> 00:08:25.019 HF, CW, HF propagation and radio scouting. including 00:08:25.019 --> 00:08:29.279 involvement with the W -2 FSR station at Forsberg 00:08:29.279 --> 00:08:32.080 Scout Reservation in New York, as well as working 00:08:32.080 --> 00:08:36.580 on the K -2 BSA staff at the National Scout Jamboree. 00:08:36.879 --> 00:08:40.100 So Nathaniel, welcome to HamTalk Live. Thank 00:08:40.100 --> 00:08:42.840 you very much, Neil. I appreciate it. Yeah, we're 00:08:42.840 --> 00:08:46.539 glad to have you back. We're on the Solar Eclipse 00:08:46.539 --> 00:08:49.240 QSO party show for the question and answer part, 00:08:49.240 --> 00:08:53.039 so this time we've got you for the whole 45 minutes 00:08:53.039 --> 00:08:56.539 and glad you could come and we'll put on our 00:08:56.539 --> 00:09:01.240 science hats here and get all the science geek 00:09:01.240 --> 00:09:04.779 stuff going here tonight, which I always enjoy 00:09:04.779 --> 00:09:07.179 getting to do that every once in a while and 00:09:07.179 --> 00:09:11.889 tie my chemistry in here a little bit. So let's 00:09:11.889 --> 00:09:17.029 talk about what we did in the QSO party back 00:09:17.029 --> 00:09:21.950 on August 21st when Ham Radio had a chance to 00:09:21.950 --> 00:09:24.649 contribute to science studying the effects of 00:09:24.649 --> 00:09:29.809 the clips. So how did the QSO party go? So the 00:09:29.809 --> 00:09:33.870 QSO party went very well. So the QSO party was 00:09:33.870 --> 00:09:37.750 an eight -hour event It took place both before, 00:09:37.950 --> 00:09:41.350 during, and after this solar eclipse was over 00:09:41.350 --> 00:09:45.350 the continental United States. We had quite a 00:09:45.350 --> 00:09:49.429 large amount of participation. We had over 600 00:09:49.429 --> 00:09:53.149 logs submitted, and from those 600 logs, we had 00:09:53.149 --> 00:09:57.990 over 30 ,000 QSOs logged. But in addition to 00:09:57.990 --> 00:10:00.570 that data, we also had observations from the 00:10:00.570 --> 00:10:02.879 reverse speaking network. WhisperNet and the 00:10:02.879 --> 00:10:05.980 PSK Reporter system. And from Reverse Speaking 00:10:05.980 --> 00:10:10.100 Network we had over 618 ,000 spots. From WhisperNet 00:10:10.100 --> 00:10:13.960 we had over 630 ,000 spots. And from PSK Reporter 00:10:13.960 --> 00:10:18.399 we had over 1 .2 million spots. So that's a lot 00:10:18.399 --> 00:10:22.360 of observations for us to look at. That's a lot 00:10:22.360 --> 00:10:27.039 of data to crunch. It certainly is. My students 00:10:27.039 --> 00:10:29.759 today were doing antacid titrations and they 00:10:29.759 --> 00:10:33.330 did two whole trials. So they had two data sets. 00:10:33.769 --> 00:10:37.090 So I think you beat them just by a little bit. 00:10:38.009 --> 00:10:41.009 Maybe. We might have a little bit more to work 00:10:41.009 --> 00:10:46.649 with here. Just a little bit. Well, after crunching 00:10:46.649 --> 00:10:52.889 all of that data and coming up with some conclusions, 00:10:53.070 --> 00:10:55.149 here's our scientific method for those of you 00:10:55.149 --> 00:10:59.509 playing along at home. What did you find out 00:10:59.509 --> 00:11:05.850 from all this data? Well, we found out that our 00:11:05.850 --> 00:11:09.830 expectation was pretty much met with the data 00:11:09.830 --> 00:11:13.850 that we collected. What our expectation was that 00:11:13.850 --> 00:11:18.649 the ionosphere would see a decrease in density 00:11:18.649 --> 00:11:23.110 due to the eclipse, and that would cause a weakening 00:11:23.110 --> 00:11:26.460 or worse propagation. Decrease in the propagation 00:11:26.460 --> 00:11:30.120 on the higher bands say like 14 megahertz and 00:11:30.120 --> 00:11:34.419 maybe some improvement on the lower bands of 00:11:34.419 --> 00:11:39.940 40 meters 80 meters and 160 meters So that's 00:11:39.940 --> 00:11:42.220 the that's the main gist of what we got out of 00:11:42.220 --> 00:11:47.620 this but one thing I wanted to say that um, you 00:11:47.620 --> 00:11:50.480 know eclipses have been studied many times in 00:11:50.480 --> 00:11:54.120 the past how is and their ionospheric effects 00:11:54.120 --> 00:11:57.379 have been studied many times in the past. But 00:11:57.379 --> 00:12:02.080 most of those studies have been fairly small 00:12:02.080 --> 00:12:05.539 scale, maybe a couple of data points here and 00:12:05.539 --> 00:12:08.340 there. A couple years ago, the Radio Society 00:12:08.340 --> 00:12:10.440 of Great Britain, they did a partial eclipse 00:12:10.440 --> 00:12:13.960 QSO experiment where they had larger numbers. 00:12:14.480 --> 00:12:18.039 This event that we ran, we have by far more data 00:12:18.039 --> 00:12:22.720 than any other previous ionosphere eclipse experiment 00:12:22.720 --> 00:12:25.259 that's happened and so that really makes this 00:12:25.259 --> 00:12:29.200 data set quite unique. Absolutely and you were 00:12:29.200 --> 00:12:32.720 kind enough to share with me some of your preliminary 00:12:32.720 --> 00:12:35.360 results you're working on writing all this stuff 00:12:35.360 --> 00:12:39.879 up right now and and notice that You know, there's 00:12:39.879 --> 00:12:42.379 some good graphs there and you were kind enough 00:12:42.379 --> 00:12:45.580 to share those. And we sent those out on Twitter 00:12:45.580 --> 00:12:49.019 and Facebook right before the show and we'll 00:12:49.019 --> 00:12:51.799 get those on Instagram here. We ran out of time. 00:12:52.100 --> 00:12:54.200 So Instagram folks, I'll get you here in a little 00:12:54.200 --> 00:12:57.799 bit. But you did have some graphs that kind of 00:12:57.799 --> 00:13:00.620 showed that. So if people want to see those, 00:13:00.899 --> 00:13:04.840 you can head over to our social media here for 00:13:04.840 --> 00:13:07.740 HamTalk Live on Facebook and Twitter and I'll 00:13:07.740 --> 00:13:10.600 get them on. Instagram again a little bit later. 00:13:11.299 --> 00:13:15.299 But that's all on the HamSci website is where 00:13:15.299 --> 00:13:19.539 this came from and we also link to some slides 00:13:19.539 --> 00:13:22.899 over there about all of this. But in reading 00:13:22.899 --> 00:13:27.580 the paper and doing a little more of the scientific 00:13:27.580 --> 00:13:34.899 write -up, I noticed that you talked a lot about 00:13:34.899 --> 00:13:39.639 the control of your experiment, which is, you 00:13:39.639 --> 00:13:44.779 know, what goes on normally, and that the lousy 00:13:44.779 --> 00:13:48.200 sunspot cycle that we're all complaining about 00:13:48.200 --> 00:13:51.379 all the time was actually good for something 00:13:51.379 --> 00:13:55.799 for once. So tell us about that. Absolutely. 00:13:56.600 --> 00:14:02.159 So, yes, we were very fortunate on the eclipse 00:14:02.159 --> 00:14:06.879 day because Overall, things were geomagnetically 00:14:06.879 --> 00:14:10.500 quiet. The sun was not very active that day, 00:14:10.740 --> 00:14:13.940 and that makes it easier for us to see the eclipse 00:14:13.940 --> 00:14:17.240 effects. I should say that we had a few small, 00:14:17.240 --> 00:14:20.840 there were a couple of small solar flares later 00:14:20.840 --> 00:14:26.179 in the day. There was one around 18 UT and another 00:14:26.179 --> 00:14:32.679 one maybe around 21 UT, but those were very, 00:14:32.679 --> 00:14:37.049 very minor. uh kp was less than three for the 00:14:37.049 --> 00:14:40.269 entire period and many of the other parameters 00:14:40.269 --> 00:14:43.990 that we look for in the solar wind and um the 00:14:43.990 --> 00:14:47.169 interplanetary magnetic field those were uh fairly 00:14:47.169 --> 00:14:50.789 normal values so we can be fairly certain that 00:14:50.789 --> 00:14:53.269 the effects that we're seeing are more likely 00:14:53.269 --> 00:14:56.389 due to the eclipse rather than due to other forms 00:14:56.389 --> 00:14:59.789 of space weather and that's something you can't 00:14:59.789 --> 00:15:02.730 control and you always hope that you get when 00:15:02.730 --> 00:15:07.269 you do some kind of scientific study and it was 00:15:07.269 --> 00:15:10.889 good for something. That's right. Absolutely. 00:15:12.269 --> 00:15:15.629 Now, can we get rid of it now that the study's 00:15:15.629 --> 00:15:21.600 over? Can we get rid of it now? Now the study's 00:15:21.600 --> 00:15:24.059 over. Let's put, let's get that solar activity 00:15:24.059 --> 00:15:27.159 going again. We have less solar activity. We 00:15:27.159 --> 00:15:29.259 can start like putting more of an emphasis on 00:15:29.259 --> 00:15:32.159 those lower bands. So, you know, there's still, 00:15:32.159 --> 00:15:37.440 still things we can do with our hobby here. Uh, 00:15:37.440 --> 00:15:39.940 but yeah, we'll, we'll start seeing things ramp 00:15:39.940 --> 00:15:43.639 up again, eventually. But one of the other things 00:15:43.639 --> 00:15:46.019 he mentioned was the idea of a control group 00:15:46.019 --> 00:15:50.000 and, um, That's something in the paper that I 00:15:50.000 --> 00:15:54.360 wrote. I took this idea of a control group and 00:15:54.360 --> 00:15:56.799 needed something to compare the solar eclipse 00:15:56.799 --> 00:16:00.740 QSO party observations against. And one of the 00:16:00.740 --> 00:16:03.679 ways I did that was I took reverse beacon network 00:16:03.679 --> 00:16:07.080 data from days before the solar eclipse and days 00:16:07.080 --> 00:16:09.399 after the solar eclipse. I was able to use that 00:16:09.399 --> 00:16:12.500 as a control group to compare with what happened 00:16:12.500 --> 00:16:18.419 during the SEQP. And you mentioned that in your 00:16:18.419 --> 00:16:21.899 paper, I noticed too, that you were just kind 00:16:21.899 --> 00:16:26.179 of overwhelmed with the number of contacts and 00:16:26.179 --> 00:16:28.899 data points that were on the air for this thing, 00:16:29.159 --> 00:16:33.320 that people really did turn out for this. Absolutely. 00:16:33.820 --> 00:16:37.299 It's taken a lot of effort to just get the data 00:16:37.299 --> 00:16:39.360 put together in a form that we could look at 00:16:39.360 --> 00:16:43.059 it. And in the paper that I've worked on, I've 00:16:43.059 --> 00:16:46.350 only used a subset of it. Of the data, I've focused 00:16:46.350 --> 00:16:48.809 on reverse speaking network data and even that 00:16:48.809 --> 00:16:52.070 subset of the data is, um, hundreds of thousands 00:16:52.070 --> 00:16:55.769 of data points. So trying to figure out how do 00:16:55.769 --> 00:16:59.110 we whittle these, the things that we look at 00:16:59.110 --> 00:17:01.870 down into a story that we can tell and we can 00:17:01.870 --> 00:17:06.529 understand. That's a very tricky thing. Yeah, 00:17:06.789 --> 00:17:10.960 always is. And, uh, You've still got your work 00:17:10.960 --> 00:17:13.619 cut out for you, but I'm glad that we're able 00:17:13.619 --> 00:17:18.000 to get some of the preliminary results and take 00:17:18.000 --> 00:17:22.799 a look at some of that. Now I know you also are 00:17:22.799 --> 00:17:27.779 offering a workshop through HamSci, which, by 00:17:27.779 --> 00:17:30.640 the way, I didn't mention the address. That's 00:17:30.640 --> 00:17:35.079 HamSci .org, H -A -M -S -C -I .org. But you're 00:17:35.079 --> 00:17:38.740 offering a workshop in a couple of weeks there 00:17:38.740 --> 00:17:42.579 where you work at NJIT. So tell us about this 00:17:42.579 --> 00:17:47.319 workshop coming up. Sure. So this workshop is 00:17:47.319 --> 00:17:51.480 going to be the first HamSci workshop meeting. 00:17:51.619 --> 00:17:53.940 And I'm quite excited about it because it's going 00:17:53.940 --> 00:17:57.200 to really be a meeting of both professional scientists 00:17:57.200 --> 00:18:00.359 and amateur radio operators coming together to 00:18:00.359 --> 00:18:04.579 talk about how can we advanced science through 00:18:04.579 --> 00:18:08.380 amateur radio. And the meeting has two main themes. 00:18:09.160 --> 00:18:11.960 The Friday of the meeting is going to focus mostly 00:18:11.960 --> 00:18:16.640 on solar eclipse observations. So I'll be presenting 00:18:16.640 --> 00:18:18.779 the observations I made from the solar eclipse 00:18:18.779 --> 00:18:21.279 QSO party. We're going to have hams from the 00:18:21.279 --> 00:18:23.859 community who've done their own experiments and 00:18:23.859 --> 00:18:27.730 also have used data from the Eclipse Go So party, 00:18:27.930 --> 00:18:30.569 they'll be presenting. We have scientists from 00:18:30.569 --> 00:18:32.950 the MIT Haystack Observatory and Johns Hopkins 00:18:32.950 --> 00:18:35.309 Applied Physics Laboratory. They'll be coming 00:18:35.309 --> 00:18:38.289 and presenting their professional observations 00:18:38.289 --> 00:18:41.529 of eclipse results. So it's really quite exciting. 00:18:42.329 --> 00:18:44.730 And then on Saturday, we're going to be talking 00:18:44.730 --> 00:18:49.150 about a newer project. We're looking at the possibility 00:18:49.150 --> 00:18:52.809 of developing a personal space weather station, 00:18:53.730 --> 00:18:58.170 a device that We would design and build that 00:18:58.170 --> 00:19:01.170 could tell you what the space weather conditions 00:19:01.170 --> 00:19:04.390 are at your local, at your particular location. 00:19:04.569 --> 00:19:07.990 And then it would send that data back to, um, 00:19:08.049 --> 00:19:10.730 MJIT and the HamSci. And we would be able to 00:19:10.730 --> 00:19:14.990 use that to say, um, get a better picture of 00:19:14.990 --> 00:19:17.369 what is going around the country and around the 00:19:17.369 --> 00:19:22.789 globe. Well, it sounds like a very unique opportunity 00:19:22.789 --> 00:19:27.890 and, uh, Sounds like a great idea and you know 00:19:27.890 --> 00:19:30.750 if this goes over real well, are you planning 00:19:30.750 --> 00:19:34.829 some more? I certainly hope so we hope this is 00:19:34.829 --> 00:19:38.130 the first of many so this is going to be a good 00:19:38.130 --> 00:19:40.390 start and then we're also hoping to be at the 00:19:40.390 --> 00:19:43.369 Dayton Hamvention and we're also Working with 00:19:43.369 --> 00:19:46.109 the with the Tapper group the Tucson amateur 00:19:46.109 --> 00:19:49.849 packet radio group. They have a digital communications 00:19:49.849 --> 00:19:55.319 convention the DCC in The fall in September, 00:19:55.319 --> 00:19:58.019 so I'm hoping that we'll have like the hamsai 00:19:58.019 --> 00:20:00.359 meeting in the winter around February when we're 00:20:00.359 --> 00:20:03.299 having it now Then we'll meet again with Tapper 00:20:03.299 --> 00:20:06.940 in the fall and then you know about six months 00:20:06.940 --> 00:20:09.539 later a little bit later Then we'll meet again 00:20:09.539 --> 00:20:12.019 with hamsai. So I'm hoping that this is the first 00:20:12.019 --> 00:20:17.529 of many Sounds like a great undertaking and I'm 00:20:17.529 --> 00:20:20.990 very appreciative of you doing that and making 00:20:20.990 --> 00:20:24.569 those connections between ham radio and science 00:20:24.569 --> 00:20:29.470 and it's a wonderful thing. So we're going to 00:20:29.470 --> 00:20:32.430 take a break but when we come back we're going 00:20:32.430 --> 00:20:36.190 to open up the phone lines and look at the tweets 00:20:36.190 --> 00:20:39.809 and take your questions about The results here 00:20:39.809 --> 00:20:43.130 from the solar eclipse QSO party and some of 00:20:43.130 --> 00:20:46.369 the science that we've been able to figure out 00:20:46.369 --> 00:20:50.930 of the ionosphere from all of that data. So we'll 00:20:50.930 --> 00:20:55.190 do that after we come back after this word from 00:20:55.190 --> 00:20:58.450 the National Voice of America Museum of Broadcasting 00:20:58.450 --> 00:21:02.019 right here on HamTalk Live.

And we've got a call 00:24:25.420 --> 00:24:29.519 right now, so let's go ahead and go to our first 00:24:29.519 --> 00:24:31.799 call of the night. Good evening. Who's this? 00:24:34.019 --> 00:24:45.079 Ben? Can you turn your speakers down there? Okay. 00:24:45.519 --> 00:24:47.859 All right. Thank you, Ben. What's your call sign? 00:24:50.220 --> 00:24:53.740 K2CPU, Keebo 2, Charlie, Havaii uniform. Oh, 00:24:53.740 --> 00:24:57.180 great. Glad to have you on here, Ben. Just talked 00:24:57.180 --> 00:25:00.319 to you here not long ago for Newsline. So what's 00:25:00.319 --> 00:25:06.079 your question here this evening? Oh, my call 00:25:06.079 --> 00:25:10.609 sign is listening in the speaker. I'm just, uh, 00:25:10.809 --> 00:25:12.890 listening about the Solar Switch Q so far. Yeah, 00:25:13.009 --> 00:25:17.390 just turned it on. And, uh, I wanted to play 00:25:17.390 --> 00:25:20.349 with, uh, Hancock Live, and Karen told me to 00:25:20.349 --> 00:25:22.970 listen, so I figured I'd give it a listen. I 00:25:22.970 --> 00:25:25.869 just wanted to say hello. I'm interrupting the 00:25:25.869 --> 00:25:28.750 show. Sorry about that. Oh, no problem. Thanks 00:25:28.750 --> 00:25:33.450 for calling in. Appreciate it. Ben's going to 00:25:33.450 --> 00:25:36.430 be on Newsline here in the morning, actually, 00:25:36.450 --> 00:25:39.769 when that comes out, so look forward to that. 00:25:42.109 --> 00:25:45.269 Were you a part of the, were you in on the solar 00:25:45.269 --> 00:25:50.549 eclipse QSO party by chance? I operated a little 00:25:50.549 --> 00:25:54.869 bit. We went down to Robert Moses Beach and we 00:25:54.869 --> 00:25:56.930 didn't do it for very long. We were on the air 00:25:56.930 --> 00:26:01.039 for about an hour or so. 50 or 60 contacts there 00:26:01.039 --> 00:26:03.599 weren't we there weren't that many people that 00:26:03.599 --> 00:26:09.140 seen but uh, at least where we were but There 00:26:09.140 --> 00:26:12.960 we made some contacts but not that many. Um Yeah, 00:26:12.960 --> 00:26:15.140 I didn't notice any effects of the solar eclipse, 00:26:15.259 --> 00:26:18.339 but uh, I like to hear the results of the scientific 00:26:18.339 --> 00:26:23.160 data Yeah, nathaniel there's there's 50 or 60 00:26:23.160 --> 00:26:26.700 of your data points Hi, ben. How are you? Nice 00:26:26.700 --> 00:26:33.230 to meet you. All right Hi. So yes, I've been 00:26:33.230 --> 00:26:35.210 looking mostly at the reverse speaking network 00:26:35.210 --> 00:26:39.269 data. And there are two really interesting effects 00:26:39.269 --> 00:26:44.190 that I noticed. One is in the 14 megahertz data, 00:26:44.549 --> 00:26:48.809 I can see a decrease in the amount of signal 00:26:48.809 --> 00:26:52.130 to noise ratio we would see as you get more of 00:26:52.130 --> 00:26:55.630 the eclipse. And the reason we believe that occurs 00:26:55.630 --> 00:26:59.799 is because the ionosphere is getting weaker and 00:26:59.799 --> 00:27:03.480 so more of the 14 megahertz rays, they escape 00:27:03.480 --> 00:27:07.339 out into space. On the seven megahertz band, 00:27:07.900 --> 00:27:10.799 we see something a little bit different. We actually 00:27:10.799 --> 00:27:16.220 see the distances you can talk to increase quite 00:27:16.220 --> 00:27:21.900 substantially as you see more eclipse. This also 00:27:21.900 --> 00:27:27.750 is because the ionosphere is thinning, the 7 00:27:27.750 --> 00:27:32.730 MHz band will just be bent less, and it's still 00:27:32.730 --> 00:27:35.589 below the critical frequency. So instead of escaping 00:27:35.589 --> 00:27:38.650 out into space, the rays just move out in distance. 00:27:38.990 --> 00:27:41.130 So those are two of the major effects that we 00:27:41.130 --> 00:27:46.089 saw in the RBM data. OK, that's very interesting. 00:27:48.109 --> 00:27:53.450 I'm sure you had a lot of data. Yeah, we. Did 00:27:53.450 --> 00:27:57.339 you judge on the sideband? of the band or mostly 00:27:57.339 --> 00:27:59.500 just like the reverse speaking network in the 00:27:59.500 --> 00:28:03.799 ZW? At this point, I've focused only on the reverse 00:28:03.799 --> 00:28:06.700 speaking network data. I think some other people 00:28:06.700 --> 00:28:09.500 have also looked at whispernet data. But one 00:28:09.500 --> 00:28:11.799 nice thing is that all of those observations 00:28:11.799 --> 00:28:15.420 are still in there, are still available. And 00:28:15.420 --> 00:28:20.099 so I would imagine that I am planning on releasing 00:28:20.099 --> 00:28:24.089 the log data. once we get it a little bit more 00:28:24.089 --> 00:28:26.190 processed, so then the voice and the phone data 00:28:26.190 --> 00:28:28.809 will be available for people to look at as well. 00:28:30.549 --> 00:28:34.289 Also, some of that should show up on DX cluster, 00:28:34.569 --> 00:28:37.230 which is also available for analysis. So we're 00:28:37.230 --> 00:28:38.890 hoping to continue to do more with this data 00:28:38.890 --> 00:28:45.789 in the future. Okay. That sounds good. All right. 00:28:45.910 --> 00:28:48.970 Well, I'm going to go back to listening. I guess 00:28:48.970 --> 00:28:51.710 I just hang up, right? Yep, you do. Thanks for 00:28:51.710 --> 00:28:55.230 calling, Ben. Appreciate you calling in and asking 00:28:55.230 --> 00:28:58.089 about this. And thanks for contributing some 00:28:58.089 --> 00:29:01.529 of that data. Yeah, thank you very much. It was 00:29:01.529 --> 00:29:05.650 really nice meeting you. You too. All right. 00:29:05.930 --> 00:29:09.180 Bye -bye. All right. Thanks, Ben. Bye -bye. 812 00:29:09.180 --> 00:29:13.839 -638 -4261 is the phone number 812 -NET -HAM 00:29:13.839 --> 00:29:17.680 -1 if you'd like to join in the conversation 00:29:17.680 --> 00:29:21.000 this evening. We're talking about HamSci and 00:29:21.000 --> 00:29:26.039 the ionosphere with the solar eclipse and the 00:29:26.039 --> 00:29:30.880 data from the solar eclipse QSO party. So yeah, 00:29:30.940 --> 00:29:33.619 you're gonna take this data and you've still 00:29:33.619 --> 00:29:37.369 got a lot more to to process here, are you going 00:29:37.369 --> 00:29:40.730 to be looking at any other trends? You mentioned 00:29:40.730 --> 00:29:46.230 what was happening on 40 and 20. Do you have 00:29:46.230 --> 00:29:48.089 any other things that you're going to be looking 00:29:48.089 --> 00:29:51.410 for? Absolutely. There's a few things we're working 00:29:51.410 --> 00:29:55.029 on right now. One of the things I think this 00:29:55.029 --> 00:29:59.230 data set's going to be very helpful with is testing 00:29:59.230 --> 00:30:04.109 ionospheric models. So there are some numerical 00:30:04.109 --> 00:30:07.940 models that have already been published or put 00:30:07.940 --> 00:30:12.180 out there that predict what the ionosphere was 00:30:12.180 --> 00:30:14.859 supposed to look like during the eclipse. And 00:30:14.859 --> 00:30:18.000 we can use a technique called ray tracing to 00:30:18.000 --> 00:30:23.160 calculate how radio waves, HF radio waves, travel 00:30:23.160 --> 00:30:28.339 through those that ionosphere. And we have both 00:30:28.339 --> 00:30:30.460 eclipsed versions of the ionosphere and non -eclipsed 00:30:30.460 --> 00:30:32.640 versions of the ionosphere. And so right now 00:30:32.640 --> 00:30:35.339 I have a student who's working with this data, 00:30:36.019 --> 00:30:40.359 the RBN and the PSK reporter data, and he's also 00:30:40.359 --> 00:30:42.720 working with some of these ionospheric models 00:30:42.720 --> 00:30:46.960 and he's trying to develop ways to test the models 00:30:46.960 --> 00:30:50.140 based on the data that we have. So that's something 00:30:50.140 --> 00:30:54.079 we have in development right now. All right. 00:30:54.160 --> 00:30:57.740 Well, it sounds like you've got plenty of work 00:30:57.740 --> 00:31:02.160 to keep you occupied and your students. So that's 00:31:02.160 --> 00:31:06.420 always a good thing. What are you looking at 00:31:06.420 --> 00:31:10.019 doing in the future with HamSci? And you mentioned 00:31:10.019 --> 00:31:17.259 trying to do some of these. sharing of results, 00:31:18.160 --> 00:31:24.059 get -togethers and workshops. What else is in 00:31:24.059 --> 00:31:27.900 the works for HamSci? I think there's a few things. 00:31:28.640 --> 00:31:30.640 One of the things we're really working on right 00:31:30.640 --> 00:31:33.650 now is You know, we have these large data sets, 00:31:33.730 --> 00:31:35.849 but they're not really designed for scientific 00:31:35.849 --> 00:31:39.349 use. You know, they're designed for ham radio 00:31:39.349 --> 00:31:42.269 use. They're designed to say you get on the air 00:31:42.269 --> 00:31:45.529 and you're like, I want to know if I can hear, 00:31:45.529 --> 00:31:49.130 you know, Russia or Germany or, you know, Antarctica 00:31:49.130 --> 00:31:51.569 or some DX country. It doesn't really give you 00:31:51.569 --> 00:31:54.470 a good measurement of what the ionosphere is 00:31:54.470 --> 00:32:00.059 actually doing. So and yet we know that information 00:32:00.059 --> 00:32:02.140 about the ionosphere is in this data. One of 00:32:02.140 --> 00:32:04.259 the things we're trying to work on is, how do 00:32:04.259 --> 00:32:07.400 we take all of this data and actually make it 00:32:07.400 --> 00:32:09.539 into something useful that can help us discover 00:32:09.539 --> 00:32:11.920 something new about the ionosphere or tell us 00:32:11.920 --> 00:32:15.799 something that we didn't know before? That's 00:32:15.799 --> 00:32:18.920 something we're working on right now. Another 00:32:18.920 --> 00:32:21.720 thing which may be a little bit easier is, using 00:32:21.720 --> 00:32:24.759 that data to give us a better understanding of 00:32:24.759 --> 00:32:28.240 what current propagation conditions are. For 00:32:28.240 --> 00:32:30.799 instance, if you go on the NOAA Space Weather 00:32:30.799 --> 00:32:37.200 Prediction Center website, they'll give you predictions 00:32:37.200 --> 00:32:40.460 saying that there's a lot of deregion absorption 00:32:40.460 --> 00:32:42.720 going on right now, or there's not, or there's 00:32:42.720 --> 00:32:45.039 a geomagnetic storm. And they give you these 00:32:45.039 --> 00:32:48.000 predictions to help people understand for one 00:32:48.000 --> 00:32:50.980 thing how it affects HF propagation, but they 00:32:50.980 --> 00:32:54.460 don't really have right now a good way of measuring, 00:32:55.200 --> 00:33:00.480 you know, is HF propagation in fact being affected 00:33:00.480 --> 00:33:03.799 by these things and how much. And it would be 00:33:03.799 --> 00:33:07.140 nice if we had a good way to take all of these 00:33:07.140 --> 00:33:09.799 observations that the RBN and PSK Reporter and 00:33:09.799 --> 00:33:12.460 WhisperNet are producing, if we had a really 00:33:12.460 --> 00:33:17.779 good way of taking that and comparing it or comparing 00:33:17.779 --> 00:33:20.900 it slash validating what some of these predictions 00:33:20.900 --> 00:33:23.160 are. So that's another thing we're working on. 00:33:24.860 --> 00:33:28.160 Excellent stuff and if you have a question about 00:33:28.160 --> 00:33:33.599 any of that give us a call at 812 -638 -4261 00:33:33.599 --> 00:33:38.559 again the phone number 812 -NET -HAM -1 and we'd 00:33:38.559 --> 00:33:41.960 love to hear from you. I've got a message here 00:33:41.960 --> 00:33:46.579 from Carl KD9HQT and he says me and my father 00:33:46.579 --> 00:33:50.099 WB9EWF did an experiment during the solar eclipse 00:33:50.539 --> 00:33:54.640 where we listen to WSM, which is a big AM station 00:33:54.640 --> 00:33:58.500 down in Nashville, Tennessee. Since the D -layer 00:33:58.500 --> 00:34:01.700 dissipated and opened up the F -layer for that 00:34:01.700 --> 00:34:06.339 time being, and his dad was at work and he was 00:34:06.339 --> 00:34:11.920 in the car and in a shack at home, but they heard 00:34:11.920 --> 00:34:17.539 the station, but it... Was about five nine listen 00:34:17.539 --> 00:34:22.679 to hand bands, but not much activity It was mostly 00:34:22.679 --> 00:34:26.940 on 80 40 and 20 which He presumed that there 00:34:26.940 --> 00:34:29.880 would be more activity since the F layer was 00:34:29.880 --> 00:34:33.679 open and the solar eclipse was happening. So 00:34:33.679 --> 00:34:36.420 He wants to know why couldn't I hear very much 00:34:36.420 --> 00:34:39.980 activity on the lower HF, but did listen mostly 00:34:39.980 --> 00:34:46.610 on on MW frequencies, but It was mostly difficult 00:34:46.610 --> 00:34:49.630 to really tell if there was a difference with 00:34:49.630 --> 00:34:53.090 the F layer open during the day and the eclipse 00:34:53.090 --> 00:34:56.230 occurring at the same time and then comparing 00:34:56.230 --> 00:34:59.530 day and night activity and lower and higher bands 00:34:59.530 --> 00:35:05.369 and all that so Any input on that? Let me see 00:35:05.369 --> 00:35:07.809 if I get this right so he's wondering why he 00:35:07.809 --> 00:35:11.469 didn't hear as much of an effect on the lower 00:35:11.469 --> 00:35:18.519 Yeah I'm not completely sure. Well, I guess there's 00:35:18.519 --> 00:35:21.320 a few ways to answer that. One is if you're just 00:35:21.320 --> 00:35:25.000 like talking on the radio, it may be difficult 00:35:25.000 --> 00:35:29.059 to actually notice a real difference unless you're 00:35:29.059 --> 00:35:33.360 carefully writing down numbers and systematically 00:35:33.360 --> 00:35:35.300 recording things. So that's one possibility. 00:35:35.760 --> 00:35:38.539 Another thing I've noticed and this is something 00:35:38.539 --> 00:35:41.539 that's worth looking into a little bit more is 00:35:41.539 --> 00:35:44.719 that I'm looking at a plot right here and I believe 00:35:44.719 --> 00:35:51.719 this is slide number, what slide number is this? 00:35:52.380 --> 00:35:54.900 This is slide number 11 in that presentation 00:35:54.900 --> 00:35:59.400 you sent out that shows the number of RBN spots 00:35:59.400 --> 00:36:02.570 with respect to time during the eclipse. And 00:36:02.570 --> 00:36:07.110 you can see that the lower bands did have a spike, 00:36:08.750 --> 00:36:13.250 the 80 and the 160 meter bands. They did raise 00:36:13.250 --> 00:36:17.750 up, but it was really only after totality came 00:36:17.750 --> 00:36:23.650 through. So the effect for those particular bands 00:36:23.650 --> 00:36:28.489 was delayed a little bit. The reason we suspect 00:36:28.489 --> 00:36:36.269 that probably occurred was because the rate at 00:36:36.269 --> 00:36:39.429 which things recombine or the ionosphere disappears 00:36:39.429 --> 00:36:44.010 when the eclipse occurs compared to how fast 00:36:44.010 --> 00:36:46.730 it reappears later, those can be different. So 00:36:46.730 --> 00:36:50.849 that might be one reason why that effect is delayed. 00:36:51.230 --> 00:36:54.730 So maybe he didn't hear as much of an effect 00:36:54.730 --> 00:36:57.210 because maybe the effect was delayed and he wasn't 00:36:57.210 --> 00:37:00.050 listening to it at the right time. Or maybe his 00:37:00.050 --> 00:37:03.030 local conditions just made it hard to hear other 00:37:03.030 --> 00:37:06.610 people. So there's a number of things. That's 00:37:06.610 --> 00:37:09.610 one of the reasons we're trying to look at these 00:37:09.610 --> 00:37:13.309 larger data sets, because you can start to see 00:37:13.309 --> 00:37:16.190 these effects spread out over large areas rather 00:37:16.190 --> 00:37:18.929 than just single points. It's sometimes harder 00:37:18.929 --> 00:37:25.710 to get the complete picture. OK, 812 -638 -4261 00:37:25.710 --> 00:37:28.510 is the phone number. And we have a few minutes 00:37:28.510 --> 00:37:33.550 left with. Dr. Nathaniel Frisell, W2NAF from 00:37:33.550 --> 00:37:37.050 the New Jersey Institute of Technology in the 00:37:37.050 --> 00:37:41.090 Solar Terrestrial Research Department there. 00:37:42.110 --> 00:37:49.170 So, give us a call. Now, what can HAMS plan on 00:37:49.170 --> 00:37:53.570 doing here in the future and how can they continue 00:37:53.570 --> 00:37:56.130 to contribute? You know, we got a lot of people 00:37:56.130 --> 00:38:00.369 on the air for this QSO party. What can just 00:38:00.369 --> 00:38:04.110 your your everyday ham do to contribute to this? 00:38:04.789 --> 00:38:06.909 Well, there's a number of things. I mean one 00:38:06.909 --> 00:38:10.409 thing is just operate so if people get on the 00:38:10.409 --> 00:38:13.929 digital modes if they get on CW if they get on 00:38:13.929 --> 00:38:17.489 phone and Use the DX cluster and spot people 00:38:17.489 --> 00:38:20.809 if they play with whisper net all of that creates 00:38:20.809 --> 00:38:24.409 data that will be able to analyze it gets archived 00:38:24.409 --> 00:38:27.670 at these different websites and We can go take 00:38:27.670 --> 00:38:31.440 a look at that That's a really simple way. Another 00:38:31.440 --> 00:38:34.619 way is, Ham's out there. You can go and you can 00:38:34.619 --> 00:38:36.920 download the data from these websites that has 00:38:36.920 --> 00:38:39.380 been created, and you can start playing around 00:38:39.380 --> 00:38:42.699 with it yourself and see what you can learn from 00:38:42.699 --> 00:38:45.579 it. If you have questions on how to do that, 00:38:45.760 --> 00:38:51.269 you can email us at hamsi at hamsi .org. Another 00:38:51.269 --> 00:38:55.070 thing, we have this upcoming project to work 00:38:55.070 --> 00:38:57.849 on this space weather station. If you follow 00:38:57.849 --> 00:39:02.269 along in QST, if you come to the Tapper DCC or 00:39:02.269 --> 00:39:05.289 talk to us at Hamvention or come to the HamSci 00:39:05.289 --> 00:39:08.110 meeting, you can get involved in the development 00:39:08.110 --> 00:39:12.750 of those projects as well. Okay, so there's some 00:39:12.750 --> 00:39:16.929 opportunities for everyone out there to get involved 00:39:16.929 --> 00:39:21.719 and tie. Science even closer to ham radio or 00:39:21.719 --> 00:39:25.780 or the other way around So good stuff there. 00:39:25.780 --> 00:39:31.480 And again, the website is hamsci .org hamsci 00:39:31.480 --> 00:39:34.800 .org and you'll find a presentation up there 00:39:34.800 --> 00:39:37.300 that has a couple of those graphs we were talking 00:39:37.300 --> 00:39:41.940 about and We sent those out on our social media 00:39:41.940 --> 00:39:46.860 sites as well So do you want to talk any more 00:39:46.860 --> 00:39:51.429 about the The 20 meter graph and the and that 00:39:51.429 --> 00:39:54.090 40 meter graph that we sent out was there any 00:39:54.090 --> 00:39:59.449 more detail on that? Um, let's see sure. There's 00:39:59.449 --> 00:40:02.670 a few other things that might be worth noting 00:40:02.670 --> 00:40:07.590 One of the things that we're we are kind of interested 00:40:07.590 --> 00:40:14.130 in are those farther away Points so you'll see 00:40:15.070 --> 00:40:17.170 Okay, so if you look at these graphs, you'll 00:40:17.170 --> 00:40:20.630 see that there's a lot of data points that are 00:40:20.630 --> 00:40:25.710 between zero and, say, 5 ,000 kilometers in range. 00:40:26.170 --> 00:40:29.349 And that distance you see there is basically 00:40:29.349 --> 00:40:32.909 the length of the United States. It's the farthest 00:40:32.909 --> 00:40:35.250 you can get from one point in the United States 00:40:35.250 --> 00:40:37.550 to another is about 5 ,000 kilometers. So it's 00:40:37.550 --> 00:40:39.829 really interesting that you can see that cutoff 00:40:39.829 --> 00:40:43.380 so clearly in the data. Then after that, you 00:40:43.380 --> 00:40:46.880 see another group of data points that goes from 00:40:46.880 --> 00:40:51.639 about 5 ,000 kilometers out to, say, 10 ,000 00:40:51.639 --> 00:40:56.199 kilometers. You can see there that those are 00:40:56.199 --> 00:41:01.679 the connections into Europe. These plots show 00:41:01.679 --> 00:41:04.480 not only what was going on in the United States, 00:41:04.679 --> 00:41:07.219 but it also shows some connections into Europe. 00:41:09.420 --> 00:41:12.199 Along with that, when we made these plots, it's 00:41:12.199 --> 00:41:15.019 required that either the transmitter or the receiver 00:41:15.019 --> 00:41:18.980 is in an area that's roughly around North America, 00:41:19.219 --> 00:41:22.079 and that was to try and capture most of the eclipse 00:41:22.079 --> 00:41:27.019 effects. It's just interesting in these plots 00:41:27.019 --> 00:41:29.199 and in some of the other plots that I've made 00:41:29.199 --> 00:41:34.610 that we see less of the European signals. in 00:41:34.610 --> 00:41:38.469 the eclipse plot versus the control. And some 00:41:38.469 --> 00:41:42.710 of that could just be because the control group's 00:41:42.710 --> 00:41:45.329 much bigger, but there's also some possibility 00:41:45.329 --> 00:41:50.530 that the eclipse actually caused those distant 00:41:50.530 --> 00:41:53.489 contacts to not be able to be made even later 00:41:53.489 --> 00:41:55.489 in the evening. But that's something we're still 00:41:55.489 --> 00:42:00.510 looking at right now more closely. So we'll see 00:42:00.510 --> 00:42:04.389 where that goes. All right. Well, that's some 00:42:04.389 --> 00:42:08.789 really interesting stuff and look forward to 00:42:08.789 --> 00:42:13.309 seeing where all this data ends up leading you 00:42:13.309 --> 00:42:16.869 in the future. And it's good to get a little 00:42:16.869 --> 00:42:19.809 bit of a peek in what you've been able to do 00:42:19.809 --> 00:42:23.110 so far. And so thank you so much for coming on 00:42:23.110 --> 00:42:26.550 the show and explaining all of that and sharing 00:42:26.550 --> 00:42:29.989 it with us. And we look forward to hearing more 00:42:29.989 --> 00:42:33.570 from HamSci. Alright, thank you very much Neil. 00:42:33.769 --> 00:42:36.750 It's been a pleasure being on your show. Alright, 00:42:36.869 --> 00:42:42.690 that's Dr. Nathaniel Frisell, W2NAF, one of the 00:42:42.690 --> 00:42:45.110 assistant research professors at the New Jersey 00:42:45.110 --> 00:42:48.909 Institute of Technology Center for Solar Terrestrial 00:42:48.909 --> 00:42:52.489 Research. And we want to thank him again for 00:42:52.489 --> 00:42:54.969 being on the show tonight. And that's going to 00:42:54.969 --> 00:42:58.980 be a wrap. for this week's HamTalk Live, and 00:42:58.980 --> 00:43:01.179 I'd also like to thank everybody out there in 00:43:01.179 --> 00:43:03.559 cyberspace for listening, calling in, writing 00:43:03.559 --> 00:43:07.139 in, and invite you back next Thursday night at 00:43:07.139 --> 00:43:11.039 9 p .m.
