After serving me for many years, my good old keyer, microham mkII stopped keying last night.
Of course this happens at the least convenient time, during a contest.
I got an idea of where the fault lies, but if any of you guys has a schematic if the MKII lying around, I would VY much like a copy.

Failed Microham MKII

  1. Hello Geir
    what’s the problem on your MK II ?
    Mine also had a problem, the capacitor across pedal PTT switch broke and shorted input, so MK II was always on TX.
    Hope it helps.
