Re: K3s won't go into transmit

[Joe Subich, W4TV-4]

Are you using PTT in CW or QSK/VOX?

Which cable are you using between MK II and the K3 - DB37-EL-K3R
(rear panel mic) or DB37-EL-K23 (front panel mic)?

Which PTT output is selected in microHAM USB Device Router for each
mode - PTT1 (mic PTT) or PTT2 (ACC jack PTT)?

73,
