[TenTec] Corsair II UV EPROM failure

[A R]

Mike,

Thanks! Pulled the P22 plug (schematically labeled "KEY/GND", and the processor keyer output is disabled, AND I still have straight key/bug CW capability. I can sure live with that.

73!

  Iam surprised no one mentioned this before 

  Unplug the two wire plug ( that is the output from the microprocessor near q3) on the 81246 logic board. 

  Problem solved!

I unplug that many times to hook up my bug or straight key.  I just plug them into the key jack once the jumper is removed.
