[Elecraft] K3 Heil Adapter, which one?

Thu Aug 7 00:36:01 EDT 2008

Elecraft K3 front mic socket (8 pin) is basically Kenwood standard, but

Elecraft forgot to check the full pin-out and mistakenly reversed two

pins that are used only on Kenwood hand mics and others not usually 

in the HF ham shack.  Do beware of this fact.  Altho it does not 

affect the Heil Kenwood adapter.
