I thought I'd give a quick try to RTTY QSO with TX5K without all the cable and software swapping (I hardly ever do RTTY), so I enabled the K3's CW-to-RTTY which seems to work great. But then I held SPLIT and got N/A. Is there some setting I missed or is this a real limitation? Sure would be nice for the quick DX QSO on RTTY. 73, Randy, KS4L
