I think Patrick raises an important point here. The FM sats are a very 
good entry point into satellite operation.

I got into satellites as a result of seeing just how easy it was to make 
contacts on AO-51 with a radio shack HTX-242 and an FT-817 that I 
already owned. Since I have been bitten by the satellite bug, I've gone 
out an bought an FT-847 and pre-amps, and I will hopefully be putting up 
a better antenna array soon to help with linear satellites.

If it hadn't been for AO-51 and its "Easy Sat" reputation, (helped along 
by K7AGE's videos on YouTube), I probably would have never gotten 
started and kept on thinking satellite operation was "too hard".
