[Elecraft] KPA500-KAT500 tuning settings

[Wes]

Abandon is probably too harsh a term. I think they will continue to produce them 
but I don't see them putting programming resources into making them work better 
with other manufacturers' products.

This despite the claim: "The KAT500 Automatic Antenna Tuner is designed to be 
closely integrated with the Elecraft K3 transceiver and the Elecraft KPA500 
amplifier although it may be easily used with other transceivers and amplifiers."

The last part is simply not true, IMHO, of course.

However this is not the case, the tuner switches to the new band settings only when HF goes through. The 15-p cable is connected and there is no K3 connected. Is there a menu setting to let the KAT500 follow the KPA500?"

>> I think you question has been answered but just for clarification -  The KAT500 needs to know frequency not band.  Even if the KPA500 was sending band info to the KAT500 it wouldn't be much use because KAT500 antenna and tuning solution selection is based on frequency not band.

>> Having the KPA500 and KAT500 tune before transmit requires something to send TX band data to KPA500 and TX frequency data to KAT500.   Following Kenwood FA is a weak (in my opinion hopelessly unsatisfactory) solution since split operation usually has VFO B as the TX VFO.
>>
>> Elecraft has been asked to revise the KAT500 firmware so it properly extracts TX frequency from IF, FA, and FB just like KPA500 and KPA1500 do.  I don't know when/if that update will be available.
