[Elecraft] KAT500 Tracking of K3 VFO

[Dick Dievendorff]

If your antenna tuner settings at nearby frequencies are similar, they don't all need to be present.  The ATU searches left and right of the tune freq for the first non-empty memory.  But if there is a stale entry from a prior antenna, it looks just as good for a Memory recall tune.

The segment widths are
10 kHz on 160
20 kHz on 80 thru 12 meters
100 kHz on 10
200 kHz on 6 meters

My 10 meter antenna, an InnovAntenna, is flat from 28000 thru 29000.  I trained at just at those two points.  More doesn't hurt, it's just unnecessary work if the antennas are flat. My 40 meter W6NL Moxon is a close second.

I thought the KAT500 divided the bands up into fixed segments and I "trained" mine at what I thought was the center of each segment ... every 10 KHz on 160, 20 KHz on 80, 50 KHz on 40/30, 100 KHz on 20/17/15/10, and I don't remember on 6.  If I'm reading your explanation right, I should have done it based on the bandwidth of my antennas instead?  That would be a lot faster, my method took an afternoon since I have more than one antenna for most bands.
