Ed, That is not something I have seen before, but perhaps the EEPROM contents have become corrupt. Since you so not have refined menu settings entered yet, I would suggest you try a Master Reset - hold the 4, 5 and 6 buttons in while powering the K2 on.
The other thing you could try is to do a Direct Frequency Entry for each band. Hold the BAND+ and BAND- buttons together and then enter a frequency within a ham band. Continue for each band. 73, Don W3FPR On 11/6/2012 1:33 AM, Edward Kleckner wrote: > I think I need some help.
