Had some #hamradio QSOs for EUHF Championship (and #POTA) from my holiday QTH yesterday. Unfortunately, my antenna here (EndFed with 1:9 Unun) was not playing very well, so I could not use more than 10 W. SSB did not work with these conditions, but at least CW did. #amateurfunk

Last week, the #WWA Sprint 2026 took place. I was able to do the required #hamradio QSOs for the basic award on Tuesday evening with my Xiegu G90 and the EFHW antenna. #amateurfunk

@funkerberg My second visit at the Funkerbergbörse in Königs Wusterhausen yesterday. Lots of #radio things, but also met local #hamradio, #meshcore and #cb operators. #Amateurfunk

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

Visited the 3. Brandenburger Antennen-Tag at the Funkerberg Königs Wusterhausen today. #Amateurfunk #hamradio

[DL7MO @dl7mo]

And number 3 of my #hamradio awards from March 2026 - the nice Diplom 50 Jahre deutsche Antarktisforschung. #Amateurfunk

[DL7MO @dl7mo]

Made the required #hamradio QSOs for the YL-WWA 2026 (Bronze level) with my Xiegu G90 last week, and downloaded the #hamaward today. #Amateurfunk

[DL7MO @dl7mo]

And another #hamradio award - the Winter Games 2026 Award. Made a precision landing with exactly 50 points. #Amateurfunk

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

I made the first version of this #hamradio cheat sheet in LibreOffice Impress, but now converted it into AsciiDoc and placed it in https://t.co/pe31NYi48u

[DL7MO @dl7mo]

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.

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

After fixing my collapsed EFHW #hamradio antenna, I was able to collect some QSOs during January 2026 for the #WWA #hamaward with my #Xiegu G90. #Amateurfunk

[DL7MO @dl7mo]

Wow - stopped my #hamradio session tonight and watched (and recorded) the amazing #aurora instead.

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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

[DL7MO @dl7mo]

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
