I brought my IC706 with MK1 keyer and Drake L7 linear to my summer location and found out something strange: with my PC/uRouter or without the PC , MK1 keys linear on CW without problems, amd the PTT1.2 MK1 LED goes red during keying. BUT, on phone (SSB or FM) with my IC elecret Heil headset microphone connected to the rear jack of MK1, in VOX mode, speaking into the microphone keys and modulates the IC706 perfectly , but MK1 doesn't activate the PTT of the linear (PTT1/PTT2 led on MK1 doesn't go on either). Audio switching ACA is used on voice. On CW, all OK PTT1/2 LED go ON and linear is keyed. So , the only way to use Heil mic is to connect IC706 palm mic to the MK1 rear connector and use its PTT while speaking into the Heil mic!!!
I suspect that there should be a VOX gain control for MK1 PTT somewhere, but without a circuit diagram I can not find out where it may be.
