Hi Bill,
No XYL requests involved but in a similar manner I have reduced the feed
lines into the shack. I have a remote antenna switch system consisting of an
Array Solutions Rat Pack with the Ten Tec interface box. This is under control
of an Elecraft KRC2 unit. It saves many feet of coax and reduces the in shack
cable clutter.
Station is K3, KPA500 and KAT500 and more Elecraft with K2 and KX3. My
issue is I'm not getting full value from the KAT500. It is capable of switching
3 antennas. But with a single feed line on position one all else is lost. So
my request would be to be able select alternative programmed values by using the
KAT 500 antenna switch. Any manually selected antenna would apply tuner values
to the antenna position but ANT 1 would remain selected. As it is now it works
but requires retuning when manually changing between selected, say, 80 meter
antennas and prior values are lost. In hardware I could do it now but don't want
to butcher the KAT500.
Well beyond my pay grade as I do not know how much reprogramming would
be required in the firmware and utility to select this as an option.
This option could possibly be done in the KPA1500 too. Certainly be a
plus in consideration of the KPA1500 which seems to have less in that there are
only 2 antenna selections available.

My most wonderful and understanding wife has requested that the number of
"wires" coming into the house be minimized. To accommodate her wishes, I have an
external antenna switch. It would be very nice if all the Elecraft tuners could
take an externally provided antenna ID to use to recall the antenna tuning
parameters. A 4 bit "band ID" would be ideal, but a command over the RS-232
interface would also work.

KPA1500 firmware will be updated to fully support such products as we identify
them. We oversized the microcontroller memory by a factor of about 8 to allow
for such expansion. In addition to SO2R, there may be other gear such as
antenna switches that we can directly control from the amp’s antenna and ATU
switches, and status can be shown on the 32-character LCD.
