[Elecraft] More on K# Shuts Off

[Bill Davis Jr]

  In my case, it may be a more complex issue. The K3 PTT is keyed by my station sequencer. (VHF/UHF/Microwave preamp and hot switch protection). When running
WSJT or Digipan the Sequencer is keyed by a OptoIsolator that is turned on by the Com port from WSJT or Digipan. This "turn-on" is not as "hard" as a normal switch or relay. I can force the K3 to stay in TX by doing a "hard" key of the sequencer.

  It is ODD since I never hear the Sequencer "chatter", it seems only the K3 TX is dropping out. The K3 PTT is a RELAY contact in the sequencer. The K3 PTT is via the rear panel 15pin connector... about a 30" cable to the sequencer. I have yet to try a ferrite core on the cable.  

  Unplugging the MH2 Elecraft mike "solves" the problem, so that is fine with me for the moment.

   Sure having fun with the K3 80/40/30m QRP, 50/222/902/1296/10Ghz via transverters .... Very Happy.
