[Elecraft] Externmal ATU

[Bill Conkling]

I have a nice new K3/100.  I am not ready to add the ATU yet.  But I have
both an LDG AT11mp and an ICOM AH-4 (in the car).  Has anyone figured how to
interface one of these tuners to the K3 so that it works off the ATU button,
just as they do with my ICOM-706MKiig?

 

Currently I'm using the LDG on the table with the radio, HOLD the TUNE
button, hit the LDG Tune button and adjust as necessary.  Release the K3
TUNE button.  It works well enough, but it sure would be nice to just TAP
the ATU button.  I'm thinking of taking it on a trip this weekend, and would
like to use the AH4 with my mobile antenna.  The required signals are
probably on a plug on the RF board, just waiting for a connector and cable.

 

Thanks....
