I should have checked for a new manual since the manual that came with my KPA-1500 has 20 Kc bins which I see are now 10 Kc bins. In addition, the tuning frequencies have been changed to 10 Kc increments. I think that is why I was getting unexplained results from the tuner as I tuned across the band. I will "re-teach" the KPA-1500 using these new parameters.

Just to make sure, however, does everyone agree the current concept is the first bin on 80m would be 10 Kc wide (3.500 to 3.510) and the correct tune-up frequency to "teach" the KPA-1500 for that bin would be 3.505 Kc ?

Secondly, the KPA-1500 would proceed to the next "taught" tuning parameters (at 3.515) when the xcvr frequency would cross into the next bin slightly higher than 3.510 ?

Would appreciate all interest parties to agree or disagree with this scenario.

Thanks for all the comments, I'm glad Electraft made the bin size smaller because feedpoint impedances can change rapidly on 80M.

Thanks, K5UA
