I have a 4 channel lowband Mitrek and need to know if anyone has a pinout for the wiring on the rear of the head along with the function of each.
Thanks

Jim, this is still embeded in my brain from the old Motrac days (1965).
Back of Mitrek head.
Cable from radio:1 mic hi, 2 mic lo, 3 spkr, 4 A+ to rx, 5 spkr, 6 freq sel common, 7 F1, 8 F3, 9 F2, 10 F4, 11audio from rx, 12 A+ to tx, 13 PTT, 14 sq pot wiper, 15 vol wip, 16 PL enable, 17 gnd from radio, 18 extender Low Bnd only, 21 shield.
19 A+ from battery
The last two pins are for the speaker.
Remember the speaker can not be grounded, it is a push pull amp-no transformer.
