I see it and it states this:

"The K3 8-pin microphone connector is wired the same as the K2 using the 
Kenwood pin-out."

The pin-out may be close to Kenwood's, but it is not the same.  I literally 
took it to mean that the K3 was pin-for-pin compatible with Kenwood's 
standard.  And that's fine for non-condenser Kenwood mics where external 
powering isn't required.  I had been scratching my head as to why my 
electret mic's output was running so low, even when the K3's high-gain 
pre-amp setting was selected.  I simply moved my electret-condenser mic from 
a Kenwood TS-870 to the K3 thinking I was all set.

To prevent confusion in the future, I recommend the inclusion of a 
disclaimer in the literature in which it states the two types are not 100% 
compatible.  At the same time, I should have conducted my own due-diligence 
and compared pin-for-pin just to be sure.
