Counting to ten is good advice in many situations. Thanks, Don; I'll try that and see what happens.

If you move the VFO just before powering down, the VFO frequency may not have been written to EEPROM yet, the process is not immediate. 73, Don W3FPR On 6/27/2021 5:21 PM, [email protected] wrote: > I just finished debugging a K2 I built this past Spring and, with > guidance from Gus, KB0YH, it was in shape just in time to try it out > in the FD.
