December ISS SSTV

Not done very well at all with the current ISS SSTV event that runs from the 21st June, or with the previous event a few weeks before. So far, I have not one single decent image to show for it. Not sure why exactly, nothing has changed here. All I can think is the station transmits earlier, completing as it approaches the west coast of Ireland and so it does not start the next one until it is south-east from me. But I can't remember how it went last time so not sure if that is even a thing. Anyway, I submitted the 'best of the worst' image, which at least has a complete top and tail, but only a fuzz for the actual image of whatever it should have been. I could crack out the Arrow and go dancing in the garden. Maybe next time...

I managed a couple of rather poor grabs from the ISS SSTV event of the 28th and 29th January. Nothing to write home about, my setup is not suitable being simply a loft mounted colinear. However, this one fragment was interesting because when received the ISS was over the middle of Poland. Not too bad for around 800 miles or so. In fact, I received another fragment after this... And two further grabs on the 29th, the first over the English channel and the second as it passed over Poland.

A combination of things finally came together. I’ve never played with digital SSTV before, plus I had some time to fiddle about and wanted to see if I could decode some of the digital stuff from QO100. Finally, I received a couple of nice digital pictures of the Dakar rally from F6HA, neatly incorporating my previous main love of motorsport! My setup is far from perfect (read, a series of accidentally cobbled together bits): Windows 10 laptop running the excellent SDR Console and connected to my QO100 transceiver via Ethernet, audio mixer feeding from the laptop and to the Linux PC, and QSSTV on the Linux PC. There is a lot of noise in my QO100 setup that I need to figure out because it really messes up analogue SSTV and seems to have made these digital modes even more fiddly. This is probably not helped by the audio running round the shack. In an ideal world I’d have a decent Windows PC with two screens and a virtual cable. That needs to wait until we sort out what is to happen with an older PC desktop here as if it is to be replaced I will nab it and…
