[Elecraft] K3 / P3 Bug?

[David McClain]

Yep... resetting the P3 did the trick. I resisted because there is no simple save / restore of the configuration like there is on the K3. But resetting the P3 fixed the problems in all areas at 6m.

Thanks for prompting me to do a more complete troubleshooting!
