I have a K3 and Ameritron ALS-600 amp running 600 watts. I have 3 antennas in use, a dipole, hexagonal beam, and 6 meter beam. The dipole requires tuning, the hexagonal beam needs tuning on 10 meters only. Both the dipole and hexagonal beam are connected to an external tuner, where I switch between them, and also switch the tuner in or out - one switch with 4 positions does this. The tuner is connected to the amp, and the amp to ANT1 on the K3. The 6 meter beam is connected to ANT2 on the K3. *If I want to use the K3 barefoot with the KAT3, I put the amp and external tuner in bypass and select the antenna at the tuner. *If I want to run the amp, I put the KAT3 in bypass and select the antenna at the tuner, either tuned or straight through. The ALS-600 input requires no tuning.
The KAT3's memory is retained by this procedure. If I forget a step, I get a high SWR warning from the K3 or amp, slap my forehead, and proceed. Both are protected from my goofs. Hope this is useful info! Monty K2DLJ > Robby, > > Since the KAT3 can be configured with one antenna port in bypass and the > other for normal tuning, why not put the amp on ANT2.
