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

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

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

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.

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

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

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

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

Here are some of my #moon pictures from the #LunarEclipse of September 7, 2025.

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

Bye bye Windows 10, hello @linuxmint.com - an update to Windows 11 was not possible anymore, so a new adventure starts...

Captured #Hamradio #SSTV images 1 to 6 from #ISS (Series 28) with my AnyTone AT-D878UV II Plus and Robot36 android app during the last days. Thank you, @arissintl.bsky.social

Since today, #WWA Sprint 2025 awards can be downloaded from #hamaward. Happy that I collected enough QSOs for it. 😀 #Amateurfunk #hamradio

Assembled the nice Funkfieber Balun/Unun Tester V3.3 XXL and the QRP Unun 1:9 from Heinrich DO1HFS yesterday. #Amateurfunk #hamradio

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

Difficult activation of Armeleuteberg DA/SA-020 over Wernigerode with the AnyTone AT-D878UV II Plus today. My first QSOs as DL7MO. Many thanks to DH1NOR, DG1HR, DB1BE, DM5UE, and DN9ALO. #hamradio #gma

Nice visit at the BNetzA today :)

Captured some #Hamradio #SSTV images from #ISS (Series 26) with my AnyTone AT-D878UV II Plus and Robot36 android app during the last days.

#FRAM2HAM #SSTV signal during today's pass of #FRAM2, watched in a WebSDR in JO62. Interesting to see the Doppler shift in the waterfall. @arissintl.bsky.social @amsat-dl.org

Copied Rabea Rogge (LB9NH) from #FRAM2 mission during her pass over Germany with my UV-K5. Unfortunately, the connection broke some seconds later. #FRAM2HAM @arissintl.bsky.social @amsat-dl.org

Activation of Klínovec with the AnyTone AT-D878UV II Plus - my first QSOs as OK/DO3MOS #hamradio #sota #gma

Activation of Bärenstein - but I could only copy DG0JMB with the AnyTone AT-D878UV II Plus today #hamradio #sbw #gma

2025-02-13: Activation of Fichtelberg - but I could only copy DM3DL with the UV-K5 today #hamradio #sbw #gma

2024-12-27: Foggy weather today, and interesting #VHF propagation. First I noticed enhanced propagation while listening to 87.9 @starfmberlin, which was sometimes interrupted by another radio station from larger distance.

2024-12-27: And again some #SSTV images from #ISS (Series 23), captured with my AnyTone AT-D878UV II Plus and Robot36 android app.

Mid of November 2024, I also captured some #SSTV images from #ISS, using the same equipment.

2024-10-15: Captured some #SSTV images from #ISS during the last days. Received them with my Anytone AT-D878UV II Plus and its original antenna, and decoded them with Robot36 app on Android via microphone.

2024-08-18: Activation of Lilienstein and Papststein in Saxon Switzerland #hamradio #sbw #sota #gma

2024-08-18: Activation of Labyrinth and Festung Königstein in Saxon Switzerland #hamradio #sbw #gma

2024-06-23: Successfully replaced the faulty encoder of the main VFO knob of my #Xiegu G90. Works fine again... 😀

2024-05-31: Yeah, this time I succeeded sending an APRS packet from my Anytone AT-D878UV II Plus (with original antenna) to the digipeater of the #ISS. The path "ARISS" worked for me.

Before going to bed at Friday, 10th of May 2024, I read on X about massive #aurora. Went out to see some northern lights but wasn't successful. Then I noticed that Panu from Finland could be heard on 11m band #cb #cititzenband. 1/2

2024-03-26: Homebrewed a #VK2ZOI half-wave flower pot antenna for the 2m band. Already attached some aluminium kitchen foil as a sleeve element to test the operation on the 70cm band.

2024-01-09: #SSTV beacon from #DB0LUD, received some minutes ago via AnyTone AT-D878UV II Plus and Robot36 app.
