is sat operations even legal on that band? 12M?

The old Russian 15 & 10 meters were cool,

I'd like to see a good old mode "A" myself. It has to be the easiest ( 
except for the FM Channel repeater on a very tall tower equivalent birds)

Extreme simple gear can get you on Mode "A"

Ive done it with a dipole on 10 and a coathanger GP on 2 and the 2 
transmitter was a FM rig with the mic disconnected and a straight key on 
the PTT. it was a little chirpy but hey worked like 30 states with that 
simple thing.
