Being creative again and building a LEO satellite antenna.

Always try to use resonant antennas and enable SWR protection!

qso365.co.uk/2026/01/the-... Bad news about a very good piece of equipment for the HAM Operator.

Yes doing fine, but less active on the satellites, more on HF.

Fine with me as well. Using it daily. Happy New Year and good health.

Wrote a blog about my experiences with the zBitx QRP Transceiver.

Gefeliciteerd. 🥳

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.

pa3ang.nl/qrp-labs-qmx... Build a QMX+. Read the story on my weblog. Use the translate function upper right corner of the window.

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.

Still using a UBX125XLT. pa3ang.nl/airband-scan.... In Dutch but use a translator.
