[Elecraft] Interconnecting KPA500 to KTA500 and ANAN7000dle

[Wes]

To add to what Jack said, several of us use Kenwood transceiver (TS-590 and 
TS-890) with KPA500-KAT500 combos.  The Aux cable is useless.  To get the KPA500 
to follow the radio frequency, here is the circuit of the homemade 9-pin cables 
we are using: https://groups.io/g/TS-890/files/Kenwood_KPA500_KAT500%20Y%20cable.pdf

Mind you this is for Kenwoods (Elecraft copied their protocol). The amp will 
query the radio VFO A for frequency and the dumb KAT500 will follow along.  The 
downside is the amp must be powered up to have the tuner track.  Also you have 
to fuss with some parameters in the KAT500 to keep it from switching tuning 
solutions during a transmission when the frequency counter disagrees with the 
serial data. (Reportedly a known bug, now completely off Elecraft's radar)

Personal opinion:  I would think twice about trying to run this remotely.

Remember, the KPA and KAT do not communicate. Instead you will need a pair of phono to phono cables for the PTT signal, and perhaps a serial cable to go to the KPA500 if the ANAN speaks Kenwood protocol.
