[Elecraft] KPA1500 ATU - ability to handle more than two antennas

[john at kk9a.com]

I use the band data from my K3S's to select the appropriate antenna and
bandpass filters.

While I'm awaiting the delivery of my KPA1500 I'm wondering if/how the amp's
ATU can accommodate more than two antennas.  For example, if I have an
antenna switch connected to one of the amp's antenna jacks is there a
facility on the amp that would allow me to choose one of two /logical/
antennas beyond the ANT1 / ANT2 physical selection?  Having two sets of
memories per band per physical port would accommodate 4 antennas.  

Does the KPA1500 support this or something similar to allow for more than
two antennas?  If not,  this seems pretty simple to implement as a firmware
change - assuming there's enough memory available.  If memory is a
constraint I suppose you could provide the option to halve the number of
tuning solutions stored per segment to keep the memory footprint the same.

Thanks,

Dan
