Received #Welle370 from @funkerberg Königs Wusterhausen yesterday at 810 kHz, about 4 km southeast of the transmitter.

It was sent directly from Funkerbergbörse, a flea market for #radio and #hamradio on the @funkerberg Königs Wusterhausen.

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
ALT My digimode setup. The G90 rests on the Eremit battery and is connected to the PC via its USB CAT cable (with a snap-on ferrite). The DIY digimode adapter is connected on one side to the G90’s ACC port and headphone jack, and on the other side to the PC’s headset jack.

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

Heard about the digital #hamradio bulletin of District Oberbayern from @dd0ul and tried to receive it in JO62 today. Forwarded the audio of my #OpenWebRX into #fldigi and successfully decoded the MFSK-32 signal. #Amateurfunk

I made the first version of this #hamradio cheat sheet in LibreOffice Impress, but now converted it into AsciiDoc and placed it in github.com/dl7mo-ham/hamradi…

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

With the turn of the year, it was also time to submit the #hamradio logs for SBW (Sächsischer Bergwettbewerb). After installing bellsoft-java11-full, I was able to prepare this using UDXLog for the first time on my Linux Mint. #amateurfunk

Last year ended with narrowly missing the "100 Years of Hungarian Radio Broadcasting" award. And the new year began with the collapse of my EFHW #hamradio antenna, caused by snow and ice. #amateurfunk

Received another #hamaward (celebrating 130th Radio and 100th IARU Anniversary) today. Took me some #hamradio QSOs during the last days. #Amateurfunk

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

Family trip to Sardinia - unfortunately very limited time for #hamradio #Amateurfunk, so only one QSO with DK3UH was possible from JM49pq.
