[Elecraft] KAT500 tune on qsy configuration

[Brian Alsop]

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.
