[Elecraft] K3: How to set Split in PSK31 Data mode

Wed May 11 19:48:47 EDT 2011

Umm, Bob:

BOTH VFO's *are* in DIGITAL D/PSK31.  The radio still wont
do split in PSK31 mode.

Methinks its in the intrnal PSK31 Decoder DSP functionality,
as Joe W4TV mentions. 

I bet you used to be an Icom user.  :)
