KPA1500 Using Multiple Antennas With the Tuner

[Jim McCook W6YA]

Jim, Thanks for the info.  You understand the problem for sure.  Dick is
being very helpful now, but I'm getting erratic data for him because
switching between antennas sometimes only results in "NEED TUNE PWR"
with OK result after a few seconds, and other times I get the fault due
to initially high SWR and high power output.  I'll probably go with
switching to STBY before applying RF to the new antenna.  That way the
instant mismatch won't create a fault due to 1800w output!  BTW I hope
your house was unaffected by the fire.  I feel badly for Bob.

Dave.... that ANT1 ANT2 arrangement will not work with my setup for
other reasons.  Thanks anyhow for the suggestion.

Jim

Jim,

I have been following the thread.  Same, same here.  K3 driving the KPA1500, using AN1 jack only to a 6 PAK that is controlled by a Bandmaster V connected to the K3 for band data.  I am going to try OPER / STBY trick when changing bands.
