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. 73 de Dick, K6KR > On Mar 1, 2014, at 10:41, Fred Jensen <[email protected]> wrote: > > Hmmm ...
