[Elecraft] K3 in AM-Sync Mode Receiving WWV

[Wayne Burdick]

This is exactly what's happening, and we're looking into a possible  
change in the way we handle it.

For now, you can leave VFO auto-tracking turned off when listening to  
WWV (tap CWT until the 'T' icon turns off). You can tune the signal in  
manually until the PLL locks (+/- 10 Hz), or tap SPOT to have it track  
the signal long enough to lock.
