I've thought about trying the narrow band digital modes on AO-40 (PSK-31 in 
my case), but I couldn't figure out how I'd ever get my Tx and Rx aligned, 
especially when you're thinking about working someone you can hardly hear.  
The only way I can think of is to move off slightly and zero-beat my 
transmit and receive to each other, then slide over and hope things are 
still lined up close enough.  But, we're talking Hertz here, and my receiver 
tunes in 100hz increments, and the transmitter in 10hz (they're separate 
rigs).

Those of you who've done this, how'd you do it?

Thanks,

Greg  KO6TH
