Today I activated #SOTA peak EA5/AT-071 "Manzorrilla" for the 1st time. It seemed a leisurely climb, 1 km away from a main road, 161 m ascent. Ha! No path! Rocks, pines and bushes. Could stay only 1 hour → 18 QSOs (FM, SSB and some CW): Xiegu G90, DX-HF-20 whip+counterpoise. As to #CW, I was very, very clumsy managing the mini pile-up in 14065 kHz. I apologize if I couldn't work all who called. All very nice and QRS for the newbie CW-er!! VY 73 ES TNX!

What are your first reactions to an outage or disaster? What if you could design your dream radio? We touch on these questions and more in this morning's episode: Round Robin part 2 of #HamdomThoughts ⚓️ https://anchor.fm/ad6dm/episodes/Round-Robin-Part-II-ep0a0s #hamradio

Pretty amazing miniaturization of this cap touch key. #hamradio

More micro-soldering! This time it's a capacitive touch key circuit based on the M0UKD design. I combined the MOSFETs into a single, dual MOSFET IC and added a voltage regulator to the input so it can take anything you'd throw at a radio.

I challenged myself to activate 6 #SOTA peaks in 12 hours. See how that one went here: https://youtu.be/hbMVr63qyTU

Listening to a worldwide net on #DMR Talkgroup 91 over the #OpenSPOT3 and #IC705. Fascinating hearing all these hams from so many countries checking in. #hamradio
I just checked and my YouTube channel has made it past 102 subscribers. I don't put out videos on a regular basis but I try to get the point across. Thanks to all who subscribed. https://www.youtube.com/channel/UCr1_qCiq5x8Jht6-STc5wxQ

Thinking I can use this Drok DC-DC boost converter to charge #LiFePO4 batts 🔋 at 14.6V from car cigarette lighter 12V.

Broke the SMA connector in my #NanoVNA. While connector arrives, temporary setup (photo). Recalibrated. Known SWR readings are now higher. My dipole used to have a nice 1.2:1 minimum around 14 MHz, now 2.4:1. Does anyone have an explanation?
