Well, I have an OMNI VI Plus  wired to a Ten-Tec Herculed II and aTen-Tec Automatic Antenna Coupler through a Ten-Tec wireing harness.  I was keying the OmniVI plus with and AEA MorisMatic MM-2 keyer.  This is the Third time the Keyer circuit in the OmniVI Plus went out.  I had also used Twice Ten-Tec repaired it.  Any Ideas?  External isolators for the keying circuit, is that the right thing to do?
   
  I have also used the Unified Microsystems UCW-100 USB to CW & PTT Interface and the same thing happend.  This has an optical isolator.  Seams to be something ealse.
