[Elecraft] KAT-500 tuner antenna switching

[Ted Edwards W3TB]

For years, I had only two antennas to switch at the tuner, but I have now
strung a third one.
And what I am finding is that the tuner switch can only identify the two
and not the third one.
Any recommendations on where I should begin to sort this out?
Thanks, gang!
