[Elecraft] K3 with a PW-1

[Dick Dievendorff]

My PW-1 follows the ICOM exciter's frequency by monitoring the CI-V bus.
That enables it to track the WARC bands, something you can't do with the
ICOM band voltage method.

The Icom series communicates band data by a variable analog voltage on a
single 
line.  The K3 (and Yaesu, etc.) communicate band data by digital signals
over 4 lines.

What is needed is a converter from the BCD from the K-3 to the various
levels 
needed by the Icom.  I built my ownYaesu/Icom interface for my FT1000MP.
When 
I got my K3, all I had to do was change the connector on the radio end of
the cable.  

If you want to build one for yourself, I can send you my notes and
schematic.  It's 
easy, but not trivial.

I believe there are commercially available units that will do this job.
