[Elecraft] Digital advice sought for K2 and K3

[Leigh L Klotz, Jr.]

You might consider getting the RS232 K2IO interface and using it for 
keying, instead of using PTT. With the K2IO, you can use rig control via 
RS232 commands with many digimode programs, which can also use the RS232 
to bring frequency, modes, filters, etc. settings to your computer.  
Having an accurate frequency display (VFO +/- AF, depending on sideband) 
helps.
