Hmmm. -40C degrees is not -95F, it is -40F. The scales come together there. This error didn't affect the content of the talk.
Fascinating. Thank you.
He should have said VLF, not (VOF-???).
👍👍👍👍👍👍
Hey, Well enjoyed🙌! I'm not really sure if it is the best time to ask but, I was wondering if I could help you create a better distribution by working on post-production like better storytelling through Edits, Keywords, think catchy intros and outros, or even some engaging short clips! Would love to chat if you're interested and keep creating good content:)
Thanks for the comment! These are all valid points, but for videos from in-person presentations there is only a limited wiggle room. If a video is filmed for publication, it is possible to take multiple takes of a scene, and pick the best one. For a pre-recorded presentation it is only possible to remove the irrelevant bits. The videos published on the channel are already heavily edited, all of them are trimmed to the point where only the bits relevant to the topic are left. As for intros, in general they are a waste of time, and (thankfully) most creators ditch them, or trim to just a few seconds. We have an outro, but barely anybody watches it.
How am I able to hear radio TG 1336 all the way here in Rockville MD clearly ?
Would not the typical green-CRT Anritsu or Hameg units, or something like a Tektronix 7L... plugin or 49x, or similar units that have been sold secondhand for 800 bucks -ish prices for a long time, be the closer comparison?
I think encryption is ok for the most part but I still wanna see transparency too
Simplex would Also be known as talk around
Do they have any Old equipment at the shop they wanna get rid of ?
What you all do with the equipment they remove
So is most of HT,s and mobile units still phase 1 ?
A sdr based scanner work's good
I had a uniden scanner the older one was deaf here in Montgomery county MD but would never shut up in FF and PW Co
Easy to look up the licensee on radio reference
I think I seen TG 1001 and 1311 and others in the 5 digit numbers too
Makes sense about the illegal carrier knocking down the system or site
Yes metro had that cellular redistribution system
I can actually hear right now FF all the way up here in Rockville MD
I still wanna Learn how to really optimize my radio and yes I can make it so it won't affiliate in the PC configure 2.18.6
Yes a Apx and xts can be setup as a nas scanner
Yea I had to create a conventional code plug for my radio and I use radio wide scan mode
The encryption sounds garbled
I can see the IDs of the units on my EF Johnson radio and the TG too it's pretty cool my EF Johnson radio is setup as a Nas scanner works ok but I would love to know how I can get it to actually track trunks it's a P1 radio but I can still hear quite a bit
I have a EF Johnson 5100 es model 3 and I can fpp it and I'm able to hear most stuff by programming the control channels from RR why is that ?
Great Fun! Great food! Great People.
Thanks! We're glad you enjoyed!
Great fun.
Great video. 73 KB3NG
Really awesome video! I have done some PCB hand dremmeling in the past, but I have not used the Manhattan construction technique. I'm surprised this is able to work so well for RF stuff considering how large it is, and all of the component leads. It makes me want to make similar systems. It could be a fun way to construct a modular synthesizer or something
Joe Carcia is a good guy. I knew him in Hartofrd when we were all a lot younger.

Spent the afternoon today at a park attempting to participate in the Virginia QSO Party as a mobile, at 2,400 ft above sea level. Back home with a log full of 7 contacts. Seven contacts from 1:30 PM to 6:30 PM. As with most contests, really a playground for the big guys. I have neither amplifier, nor 100 foot tower, nor 80 meter capability, nor dipole higher than 23 feet-so… not really fun. Unless you’re in the six-figure-points-total crowd, it’s like entering the Indianapolis 500, in your Chevy Nova. Somebody suggested “go for a new personal best… try to decrease your time for 4 laps… then go home.” Unless you’re a fanatic, lots of other things you can do on a spring Saturday are more fun. Preceding just MY story-probably not YOURS-but I’m sticking to it.
Hey, submit your log anyway, even with 7 contacts! You still will be 7 contacts better than the logs with 0 points! And if you are in VA, even 0 points will earn you a beautiful certificate, which you can hang on the wall :)

Thanks for the video. I learned a lot. I don’t have a 3D printer but I really liked the wire winder antenna holder combination. It makes the antenna setup and breakdown so much easier! 73 George KB3WAQ
Thanks for the nice comment! If you are in the US, in many places public libraries offer access to 3D printers. You can also try to ask in your local club if anyone could print a winder for you, or contact a nearby makerspace.
Thanks for info@@ViennaWirelessSociety
Excellent presentation. I'm curious, you used 18awg copper magnet wire, do you know if 16awg could be used with an FT240-43 transformer? I know it might be a little stiffer to wind but might it otherwise work?
It depends. Thicker wire has lower resistance, what will reduce resistive losses in the windings. On the other hand, thicker wire means smaller distance between windings, what can increase losses caused by inter-winding capacitance. Probably the best way of figuring out is to build two identical transformers, and measure them connected back-to-back. MM0OPX has a great demonstration of loss measurement using this method: ruclips.net/video/TZjY2Jim7fY/видео.html Of course the winding has to fit on the core, but I don't think it will be a problem in your case.
@@ViennaWirelessSociety I appreciate you taking the time to respond. Thanks!
@@gsudman It is worth noting, that the gains from increasing wire diameter will be limited by skin effect. According to the graph in wikipedia (en.wikipedia.org/wiki/Skin_effect#/media/File:Skin_depth_by_Zureks-en.svg), at 1MHz the current penetration depth for copper is ~0.07mm. This means that the decrease of wire resistance will be proportional to the wire circumference (i.e. wire diameter in the first power), instead of the cross-section area (i.e. diameter squared), what is a case for DC currents. On the other hand, FT240 is such a large core, that the increase in losses caused by capacitive coupling. I think this is a great excuse to do some for some experimentation, and share the results :)
Forgot to mention - the audio output on the tinySA makes it a WB receiver, just like SDR, with the waterfall display as well.
I use a $15 noise source with the tinySA to characterize filters. Works great!
Good information. Note every furnance is the same however so one has to really consult the proper documentation and resources. Here you are not allowed to do any work or modifications to a furnance/AC. Warrenty, home insurance and gas company fines or void insurance. Not something we can do here.
I bought the tinySA Ultra ... even better
Well done. Going to recommend this video to my clubs. Thank you.
Tinysa is an amazing instrument 😊
Completely agree!
This is a interesting topic John. What I am wondering is could this antenna somehow be used for a Free to the Air TV ?? Please drop a line on what you think Sir.
Nice project. Far too many inserted ads (every 5 minutes)
This channel is not monetized. If you see ads, blame RUclips. We don't get a single penny out of what YT shows to viewers.
Agreed. I wonder why there were so many ads on this single video and just the normal 2 on most others. I hope you monitor and watch your videos via an outside account to see just how many commercials are inserted. PS. I subscribed and gave a thumbs up. Best 73@@ViennaWirelessSociety
@WECB640 Without monetization we have no control over how many ads are shown, and where. It is completely up to YT's advertising algorithm to show them. Apparently, it's decided that this topic is popular enough to stuff the video with ads. This is sad, but there is nothing we can do at this point.
great presentation but also great AV production - loved the consistently good audio and the camera skills. Thanks for all the references, too.
Thanks!
What would the effects on performance be if you modified this using PVC of greater diameter, effectively shrinking the length even more.? Just thought a long stealthy antenna could be built by wrapping copper tape directly around a wooden telephone pole 12 inches or so in diameter.
I can't tell what would be the effect of increased diameter, but a soggy, wooden telephone pole would greatly increase losses.
Really nice ! I have a bunch of that stuff here also ! Thank You for the video ! KE6QK
Liked and Subscribed ! Thank you so much for this content!
As a listening only station, spotting is my only tool. I've already spotted 5 continents. Only Antartica is missing!
Thanks for uploading this video. Very useful explanations and has given me some great info. Cheers and 73 from VK
