Dale,
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 bunch of fixed component tuning networks, one per antenna might be a
practical alternative if one can live with the bandwidth. L networks
are easy and pretty cheap to make. I have an manually tuned L network
box here that I use to find out what values of L/C are needed. I think
those who are fortunate enough to have a KAT500 might be able to use it
to determine needed values. Can the KAT500 values of L/C and whether an
antenna side or rig side cap is required be read out?
If one has engineered a complex system of antennas like yours, then why
not also engineer a flexible, programmable solution that automatically
handles the needed fixed networks as a function of user input (if any),
mode, antenna and frequency. Tune the antennas for the most frequently
used mode and switch in networks when required for other
modes/frequencies. This is quite practical (for HF) with even a el
cheapo PIC and some relays.

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 a directional set of LB, and a
directional set of HB (split at 20m,for this example) with a 6 pole
coax switch outboard towards the antennae from the tuner... then the
memory doesn't do anything but slow you down in antenna changes.
Have a great day,

, "Why would you NOT want Memory Recall Tune on QSY checked?" Seems
like having it checked is the fastest way to get to the new tuner
settings if it has tuned up on that frequency before. And if it
hasn't tuned up on that frequency before, it will if you are in Auto
mode.
