Ham radio operator since April 2023. Old callsign DO3MOS was replaced by new callsign DL7MO in May 2025. Please see https://mastodon.radio/@do3mos for past posts.
Made the required #hamradio QSOs for the YL-WWA 2026 (Bronze level) with my Xiegu G90 last week, and downloaded the #hamaward today. #Amateurfunk
My last two #hamradio QSOs yesterday were in FT8, so here’s a small picture of my digimode setup. The DIY digimode adapter sends the TX audio to the Xiegu G90’s ACC port, but it receives the RX audio from the G90’s headphone jack instead (from ACC does not work). #Amateurfunk
Just worked the DXpedition J51A in Guinea-Bissau 🇬🇼 with my Xiegu G90 on the 15m #hamradio band. My first successful operation in split mode, very interesting. 🤗 #Amateurfunk
I made the first version of this #hamradio cheat sheet in LibreOffice Impress, but now converted it into AsciiDoc and placed it in https://github.com/dl7mo-ham/hamradio-cheat-sheets

During my last #hamradio summit activations I missed points due to remembering some rules incorrectly. To prevent this, I have created a small cheat sheet for my favorite #Amateurfunk activities #SOTA, #GMA, #SBW and #POTA.
Along with that, I also received the #hamradio award for last year's Sächsischer Bergwettbewerb #SBW two days ago. Curious how many points I'll manage to collect this year. #Amateurfunk
In the mountains I always enjoy activating summits with #hamradio. Last week I missed some QSOs to earn #SOTA points from Klínovec, but at least managed to collect 2 points for Sächsischer Bergwettbewerb #SBW. #Amateurfunk
Wow - stopped my #hamradio session tonight and watched (and recorded) the amazing #aurora instead.
First test QSO with #FT8CN, #Xiegu G90 and DV27S mobile antenna. No cable connection at the moment, just sound transmission through the air (and PTT directly by hand).
To be able to run FT8CN on the old #Samsung Galaxy S4, I installed Lineage OS 18.1. #hamradio #Amateurfunk
And also interesting, that log-periodic antennas are used very often to receive TV.
