Sorry for the inadvertent premature posting. I'll try again -
After I had posted my observations on the behavior of KAT500 "Tune on QSY"
option I suggested to an owner of a TS-890S, KAT500, and KPA500 that he should
try disabling the QSY option as it might cure his annoying re-tunes during
Please ignore previous post. It was inadvertently send before editing was

Hi KAT500 gurus,
I'm trying to understand the KAT500's Tune on QSY configuration tab.
The way the KAT500 works is if you have trained it so that it knows the L-C
combinations needed for a particular frequency on a band, when you return to
that frequency it can simply recall those values by
I would turn it off if changing to a new antenna. You don't want it to
autotune with the old values.
Turn it back on after 'training' the tuner to the new antenna.

The memory remembers what the setting/tuning is per freq... but doesn't take
care of the second, third or fourth wire antenna being fed on the same freq.The
ant1 - ant2 works well for just two antennas on the same freq, but say you have

Initially the tuner did not retune on in-band QSY. Then we added in band memory

I guessed that there might be a good reason for a few users to prefer the old
behavior. So I provided a mechanism to turn off the

I agree.
Autotuners for many of us who do frequent fast search and pounce can
indeed slow things up. The last thing you want when trying to pounce on
a rare one (before the mob arrives) is to have the amp off line-- even
for half a second.
The best tuner is none.

A lot of the need for a tuner here would vanish if the KPA500 could
handle a 2.5:1 SWR. Phone-CW band excursions could be tolerated
without exceeding that limit. I've looked at the voltages and currents
involved. At 500 watts, they don't intractable.
I wonder if the incremental cost would
That would only be effective on antennas that are mostly resonant in the
chosen band(s) which many designs do not allow. Not everyone uses a
resonant antenna for a variety of reasons (HOA, space limitation). (I have
HOA limits but hide a 104 meter EDZ wire.) Otherwise a narrower ranged
tuner
