Wow, this would be great if we are in the footprint. I might finally get 
a chance to use the 2.4 GHz transverter I built back in the AO-40 days.

And with the cheap LNB's we've been playing with on 10 GHz, receive 
would be pretty easy. I built a 10 GHz receive system here to monitor my 
10 GHz beacon on a mountain for around $15. Uses a surplus DSS dish and 
my FUNcube for an IF.

Here's a typical type LNB we've been playing with. They work well! 10.4 
GHz would come out at ~ 650 MHz.
