VK2TTY he/him<a href="https://f.kawa-kun.com/profile/tk" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@tk</a> would that one also be a common mode choke? Blocks DC on the shield and thus the RF noise (and your own transmissions—ouch!) that’d otherwise get picked up by the field around it. At the antenna feed point, prevents using the shield as a counterpoise. Further down, trims that counterpoise. At the shack wall, said to prevent RF from “entering the shack”… but now I think about it, I’m not 100% on why the position would matter for that? Nor, why I’ve been told to put one at both ends? <a href="https://mastodon.radio/tags/HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HamRadio</a>

Neil E. HodgesI don't think the big sleeve balun I've been using is working so great, what with all of the radio waves bouncing around and off the stucco walls of my balcony. Going to build <a href="https://www.vk6ysf.com/balun_choke_balun_low_vhf.htm" rel="nofollow noopener noreferrer" target="_blank">one of these</a> to use instead. Already got the supplies for it! 👍<a href="https://f.kawa-kun.com/search?tag=AmateurRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AmateurRadio</a> <a href="https://f.kawa-kun.com/search?tag=HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HamRadio</a>

Mike (VK1OMG) 🏴‍☠️ 🦀Sitting here idly watching aprs.fi wondering how to nix the ads & thinking about what I could use APRS for out here in the burbs when up popped a new icon. A guy doing a SOTA activation.That I guess, for a start. <a href="https://mstdn.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a>

Wes AFØAJHad a great <a href="https://mastodon.radio/tags/POTA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#POTA</a> activation at US-0460 today. It’s only been activated 16 times, which surprises me. Worked Hungary again, and France! Every time I do this, I think I probably enjoy it even more. <a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a> <a href="https://mastodon.radio/tags/ParksOnTheAir" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ParksOnTheAir</a>

Andreas, DJ3EI, he/himUnser schönes Amateurfunkhobby ist vielfältig, hat eine Menge Spielarten. Auf dem <a href="https://mastodon.radio/tags/EH2025" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EH2025</a> durfte ich eine Einführung geben, gedacht für Leute, die auf Amateurfunk neugierig sind, aber noch nicht viel darüber wissen.Die Einführung wurde als Video aufgenommen: <a href="https://media.ccc.de/v/eh22-17-amateurfunk-ein-magisches-labyrinth-von-kaninchenlchern" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://media.ccc.de/v/eh22-17-amateurfunk-ein-magisches-labyrinth-von-kaninchenlchern</a> .Wenn die englische Übersetzung kommt und Du mich lieber im deutschen Original hören willst: Das Video erst herunter zu laden hilft.

Wes AFØAJ🤬 I had great plans to do a CW <a href="https://mastodon.radio/tags/POTA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#POTA</a> activation in about 10 minutes. Alas, guess who forgot that the IC-7000 needs a 1/4” key plug? Yeah, me. Maybe my dad has one I can borrow for the trip back home… Well, SSB it’s gonna have to be. US-7845 here shortly. <a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a>

Diane Bruce VA3DBIf you ever need an odd voltage regulator and you don't mind using a 7805 or 7812 using a LED from the ground pin to ground will up the voltage regulated. <a href="https://www.electricalengineering.xyz/led-voltage-drop-by-color/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.electricalengineering.xyz/led-voltage-drop-by-color/</a> Just be sure to black out the LED or it will induce 50 or 60 Hz hum into your projects! (Yes a normal silicon diode works but what's the fun in only .5 or so volts?)<a href="https://mastodon.radio/tags/HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HamRadio</a> <a href="https://mastodon.radio/tags/AmateurRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AmateurRadio</a> <a href="https://mastodon.radio/tags/Electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Electronics</a>

Andreas, DJ3EI, he/himDie <a href="https://mastodon.radio/tags/UKWTagung" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#UKWTagung</a> Weinheim ist eine Veranstaltung rund um *alle* Frequenzen und Spielarten des Amateurfunkhobbys. Der irreführende Name stammt aus der (durchaus glorreichen) Vergangenheit; die UKW-Tagung findet am 13.9.2025 zum 70. mal statt! Sie braucht m.E. den Vergleich mit der <a href="https://mastodon.radio/tags/HAMRadioFriedrichshafen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HAMRadioFriedrichshafen</a> nicht zu scheuen. Mein Vergleichsergebnis: Ähnlich, nur kürzer, kleiner und familiärer.Der "Call for Papers" ist raus.Vortragsidee? Lust?

Owen MeheganWeek 17 of the <a href="https://mastodon.au/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a> <a href="https://mastodon.au/tags/hamchallenge" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamchallenge</a> (HC17S) is to find the repeater closes to you. Technically, the one closest to me is VK3RDQ, but I can't hear it from my location. This is perhaps not surprising, as it is only 68m elevation. The next closest is probably VK3RML or VK3RMS. I can hear their IDs from here with my HT. However, like in many places these days, there is very little activity on any of these repeaters. There are at least seven which are probably reachable from the metro Melbourne area, and they're all idle 99% of the time. It really seems like the community would be better served by consolidating onto one or two systems.<a href="https://mas.to/@hamchallenge" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@hamchallenge</a>

TribesmanJohn 🇦🇺🌏👨🏼‍💻📷It's not often that a day when I can use the AX Prefix, my motivation, and the readiness of my radio equipment all coalesce.So far I have made over 100 contacts as AX7BEN today and still going strong. Probably in the last 3 days I have made almost as many contacts as I have done in the previous 20 years of having a license.<a href="https://aus.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a> <a href="https://aus.social/tags/amateurradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#amateurradio</a> <a href="https://aus.social/tags/ft8" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ft8</a>

Chris / AF0CXI'm really starting to fall in love with my VX-6R.

Michael K JohnsonTonight I made a "capacity hat" for my ultra-portable Elecraft AX1 HF <a href="https://social.makerforums.info/tags/HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HamRadio</a> antenna.I found a <a href="https://youtu.be/SE2EtVw9lho" rel="nofollow noopener noreferrer" target="_blank">video by LY2H Linas</a> where he made one based on an alligator clip to make the same antenna resonant on 20m to use with an IC-705. I remembered that I had a box of those clips and got to work.First I cut off the wire connection from the back (to make it more compact) and filed off the sharp edges.Then I cut 2 x 245mm pieces of 14AWG solid copper wire, and cut the middle ~15mm of insulation off of each of them. I used a soldering gun to have enough power, and soldered each wire to the back of one side of the remaining clip. Then I bent the wires out into an X.

Dan KB6NU20 contacts on my first 2025 POTA activation today at US-3315. Worked coast to coast on 20 meters. <a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a>
