[Elecraft] K3 Digital modes

[Lance Collister, W7GJ]

Hi Greg,

The K3 is the most "digital friendly" rig you can get!   You are right - you just 
hook up the AUDIO OUT and AUDIO IN on the back of the K3 to the opposite LINE IN/MIC 
and LINE OUT/HEADPHONES of your computer sound card.   The PTT can be controlled via 
the RS232 cable from your computer to the K3; you have the choice of either using the 
RTS or DTR lines for PTT.  All the options are selectable from the MENU option on 
your K3 ;-)

Have fun with it!   VY 73, Lance
