Dave, Do you own either/both the KPA500 or KAT500 and are familiar with their operation?
The KPA500 is not involved in the receive path, it is only used for transmitting, so it doesn't cause an issue on receive. When in standby the amp is bypassed and the T/R circuit feeds the input to the output. That output is connected to the KAT500 input. My antenna system, for various bands, is connected to the three outputs. Yes, if I just want to monitor a number of bands/frequencies I can press the KAT500 mode button repeatedly until the unit is in BYPass so that it won't attenuate receive signals. Unless the KAT500 is bypassed the last tuning solution will be applied regardless of band or frequency selected on the rig. Then, for each frequency I want to monitor, I can then press the ANT button on the KAT500 repeatedly until the correct antenna for the desired frequency is selected. Depending on the memory or VFO band/frequency selected it may be necessary to do this repeatedly. This will not work at all in the case of scanning. When done listening on various bands/frequencies and I want to return to transmitting I have to press the KAT500 mode button repeatedly until the unit is in MANual. Then press the ANT button on the KAT500 repeatedly until the correct antenna for the desired frequency is selected. All off this is doable but I'm looking for a more automatic system like that built-in to the Elecraft equipment. It appears that I need to design and build what I want. I've taken up more than enough forum time on this subject so it can be closed.
