[Elecraft] KPA 500 Question

[G4GNX]

Also, many people forget that the KAT500 works on RX as well as TX and provides a band-pass filter which changes position across tuning segments.
If you’re using the KAT500 without the Aux cable and the main TX antenna for RX, as soon as you tune the RX away from the current tuned segment, the RX path is no longer at optimum.
