My first FT4 QSO on #RS-44 was made with MM9SQL! Always fun to work him.

A promising #AMSAT #SO-50 pass completely ruined by a few stations claiming the satellite full time. Where is the HAM spirit.

Created a QRP-Labs QMX Controller with clickable DX Cluster and POTA spots and much more. See github.com/pa3ang/QMX-C... for source code, windows executable and extensive manual.

I was hoping to demonstrate this last weekend at RetroFest 2026. A true 8-bit Pocket Computer running CP/M on an 8Mhz Z80. On board storage, USB-C or battery powered, internal module bay and full RC2014 expansion bus. It runs Microsoft BASIC and Zork. So it's called the Zorkulator. Please share.

A Pocket Computer on a desk. It is the footprint of the first Pocket Computer - the Sharp PC-1211 (or Radio Shack PC-1)

Is amateur radio dead? Right now, on 11 meters between 27.400 and 27.800, at least 50 SSB frequencies are in use by radio enthusiasts. How sad is it then that from 28300 to 28700 absolutely no one can be heard... I think the difference lies in being enthusiastic. The old grumbler has spoken...

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.

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