Yes, you can do this if your amp is close by – and you remember to do it when necessary. I use a couple of different amps and autotuners: The KPA500/KAT500 and an ALS-600/MFJ-998. I leave all autotuners in MANUAL mode and memorize settings. When I change bands, I like to press TUNE to check SWR before operating even though the memories have been set – just in case something has changed – and it would be nice if I just put out a 20W carrier (I leave my K3 TUNE set to 20 watts as suggested for best KAT500 tuning). So when I press TUNE, I get almost full power out of the KPA500, and 200-300 watts out of the ALS-600. The KAT500 follows band changes via the accessory cable so if nothing has changed in the antenna system, there is no amp fault. With the ALS-600/MFJ998, the MFJ-998 requires some RF before it can determine the band. Often you have a momentary high SWR that trips out the amp when changing bands. Not that big a deal. But for my set-ups, I wish the K3 amp-enable output was programmable so it could be set OFF on TUNE. But I understand this is hard-wired and so can’t be done.
