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.
