[Elecraft] KAT500 follows K3 RX freq

[Andy Durbin]

" All I do is change RX frequency on the K3S and every thing else follows.  No RF required to switch things to the correct configuration for band, frequency and antenna."

I think that having the KAT500 follow the K3 RX frequency is a really poor system design.  The tuner, and the tuner's frequency dependent antenna selection, should follow the transceiver transmit frequency.  Why does it matter? Well one day you will transmit with a large difference between TX and RX frequencies into the wrong antenna and with the wrong tuning solution.  This will fault the KAT500 and/or the KPA500 and could possibly cause damage.

It actually works a lot better if the KAT500 and KPA500 follow the rig TX frequency and are properly configured before the transmission starts.
