The #ISS #SSTV is underway. There are reception reports already! The first pass over my location is at 19:30.

I have got the QFH antenna working at my temporary QTH, in readiness for the #SSTV #ISS event. But just to prove it was working I had a play with APRS.

We had meatballs. Looked at office furniture. No batteries. Spent loads of money.
New shack furniture.

If you have a Rig Expert antenna analyser and need a case, then these electric toothbrush cases work really well. With thanks to K8MRD's YouTube channel for the suggestion. PLUS, Rig Expert are in Ukraine, good to support them too. 🇺🇦

I gave up on the #ISS #SSTV project a few days ago, bored with the duplicates! Six good images.

Off to a good start with the #SSTV event from the #ISS I could do without Storm Amy, and I got some odd looks standing in the rain and wind waving the Moxon at the sky!

Clearly yesterday propagation was just messing me about as I was testing the new "non resonant long wire 9:1 unun" antenna at my temporary QTH. It's all looking lovely today with 5 watts from my 705.
Received signals on FT8 shown on world map. AUSTRALIA!

New Iambic key arrived today. Never been a squeeze keyer, but this looked too good to pass up. #morse #hamradio

I am house and cat sitting for friend for a few days. Chucked a bit of wire over a tree and had a play with #WSPR. #hamradio #cats #QRP

Another SDR rabbit hole to get lost in. ADS-B data. Surprisingly easy to receive and decode. #SDR #ADS-B

That's it. #SSTV event has ended. Some success, some failures.

Final montage of images from series 28. I am not able to catch the last few passes this evening. Plus, waving an antenna at the sky on a hill in a thunderstorm might be sub optimal. #ISS #SSTV
