LeahFinally have a permanent <a href="https://chaos.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> setup in my home office, after years of setting up temporarily and either sweating or freezing on my patio… this is so nice.

Michael K JohnsonI recently took my KX3 on a trip, and didn't take my QRP unun because I wasn't bringing any "UHF" style connectors at all. I tried using binding posts on the radio to run my 33' random wire antenna with 13' counterpoise, but I got too much RF making noise in the earbuds, so I switched to my linked dipole and got a coast-to-coast-to-coast POTA activation on 5W. Success! But... I was carrying wire antennas that I found I couldn't use. 😢To try to fix this in the future, I've changed the design of the unun box again. Instead of a PL-239 "UHF" connector in the bottom, I'll run a couple feet of RG316 through the side of the box and put a BNC connector on it to connect close to my KX3. However, that proximity made me think seriously about the high voltage on the binding posts; previously, I was expecting them to be 20 feet or more away from people and didn't think enough about it. 15W into 50 ohms through a 49:1 transformer is over 1300V out the EFHW port, and even at the 9:1 random-wire port it's almost 250V!I am using 3d printing heat-set inserts as tiny binding posts. I now realize that I could just 3d-print small knobs and heat-set the inserts in those knobs. I don't have to add a lot of bulk, but I can both make this safer and easier to use. The knobs I designed look big in the model, but they are 10mm max diameter and 7mm high. This unun box is just ridiculously small!This will be substantially less bulk to pack in with the KX3, and more useful.<a href="https://social.makerforums.info/tags/HamRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#HamRadio</a> <a href="https://social.makerforums.info/tags/AmateurRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#AmateurRadio</a> <a href="https://social.makerforums.info/tags/POTA" class="mention hashtag" rel="nofollow noopener" target="_blank">#POTA</a>

KC1UDNSo today I built Salty Walt's (K4OGO) 17.5 antenna, lashed it to the side of the porch, hooked up my new G90, and promptly made a contact in Hungary. First DX contact and first HF contact that was not during field day.I am just getting started.<a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a>

Gary @N8DMTYou know its a slow work day when you’re cleaning RF connectors just to keep busy…Some of them were pretty good — others were in desperate need of some attention by the cleaning cloth/brush.<a href="https://mastodon.radio/tags/HamRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#HamRadio</a> <a href="https://mastodon.radio/tags/RFtest" class="mention hashtag" rel="nofollow noopener" target="_blank">#RFtest</a> <a href="https://mastodon.radio/tags/ElectronicsTest" class="mention hashtag" rel="nofollow noopener" target="_blank">#ElectronicsTest</a>

Michael MarekAmateur Radio Post: The band must be up. That last couple of mornings, I have been hearing a repeater 150 miles away, including a lengthy rag chew this morning.

In 2011 when he was working on his PhD at UC Berkeley, he participated with the Stratofox Aerospace Tracking Team.

And 6 years before Woody was in the 2017 NASA astronaut class.

Alex KR1ST/PA1STInteresting. The time honored tradition of calling CQ or searching for a signal is now considered an insurmountable burden?<a href="https://forums.qrz.com/index.php?threads/introducing-rtqm-qrzs-real-time-qso-manager.961101/" rel="nofollow noopener" translate="no" target="_blank">https://forums.qrz.com/index.php?threads/introducing-rtqm-qrzs-real-time-qso-manager.961101/</a>"Rather than searching the bands endlessly for a weak signal..." Huh? Strong signals be damned?I'm not sure what to think of it. I utilize similar tools on VHF+, but that's just because activity is so low on these bands that calling CQ outside of a contest is almost an exercise in futility.<a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://mastodon.radio/tags/AmateurRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#AmateurRadio</a>
