New KPA1500 feature: ATU TUNE integration with K3 and K3S transceivers


If your KPA1500 is connected to a K3/K3S via the ACC cable, you’ll be able to tune the amplifier’s internal ATU without touching any controls on the transceiver.

For a manual tune, all that’s required is to tap the ATU TUNE switch on the amplifier. (Originally, three switch presses were required, because of the need to start and stop TUNE at the transceiver. This will now be handled automatically.)

For SWR-based re-tunes, the amplifier can now complete the ATU tuning cycle quickly even in SSB mode, with no operator intervention required.
