[Elecraft] K2: VFO stuck on 15M

[Don Wilhelm]

JT,

Those symptoms could indicate that the 15 meter entries in the EEPROM 
have been corrupted.
Try running CAL PLL before doing anything else - don't forget to plug 
the frequency counter into TP1 and switch to 40 meters.

If CAL PLL does not correct it, record all your menu entries and try a 
master reset - then run CAL PLL and use CAL FIL to re-do the filter and 
BFO settings.

There are just no hardware problems that I know of which could cause 
that behavior on only one band - all bands, then yes it would likely be 
a hardware problem, but not a VFO failure to tune on one band.
