Inspired by Richard, 9W2CBL's blog and his comments about AO-51, I thought I'd see if I could possibly hear and maybe even work through the AO-51 satellite from the car.
On the train this evening, I googled the AO-51 up and downlink frequencies and appropriate details and when I got to the car I programmed up a couple of memories in the FT8900.
So, I'm all set! All I need to do now is to keep listening and hopefully, one of my journeys will coincide with a pass of AO-51. I shall take a look at the prediction software and see if there are any likely passes of the satellite.
You can see where AO-51 is here
Tomorrow evening at around 1840z looks a good pass here - if the train is on time! You can find predictions for your location here
