Wrote a blog about the UV-5R Mini. Use the translation button for English. pa3ang.nl/uv-5r-mini/

Very cool to see WSJT-X 3.0 has Cloudlog support baked right in :)

After reading the post from @robertdl3rr.bsky.social regarding a retro-comp sc131 kit I bought one and here you can find my build experience. pa3ang.nl/sc131-cp-m-c...

Ordered one as well because of your post. RomWBW seems very good and this little package does suit my need to go retro again. 🤭

Luckily Hans does know how it works. 😀

Not insane I just paid less than €4. It depends on the declared tariff code / usage here in Europe.

Thanks. Is weer mijn oude stijl van blogs schrijven. Was ik 5 jaar geleden mee gestopt.

A complet new line-up of FM birds active now with very good performance. AO-123, SO-124 and AO-125. See Amsat for details.

My first contact on AO-123 was with Bill.

Discovered AO-123 FM satellite. Very stable downlink reception and transponder is very sensitive on uplink. Only few stations active on this bird.

QSL received using Clublog’s OQRS for QO-100 QSO’s. 😀

No issue in getting contacts in phone with my QMX on 20 meters.

A Sinclair ZX81 computer

THIS was a strange keyboard! I wonder how many people had this as a first computer? I did!

Started homebrew again with a very nice kit from Radio-Kits. Read my blog on the build of the Explorer for 20 meter. pa3ang.nl/radio-kits-e...

Did a remake of my old online receiver service active from 2003 till 2013. The birth of what later became websdr. Just live for testing and fun.
