I’ve had a few QSOs though amateur satellites. I bought a dual-band antenna from a company in the US and used a cheap Chinese handheld and my 20 year-old FT817 for the uplink and downlink. There was a surprising amount of activity, really tricky to make myself heard.

I saw somebody was creating a BBS for meshtastic like it’s 1999.

That’s a cool antenna.

Some years ago I built an antenna for NOAA weather sats
