[Elecraft] USB/LSB Problem

[Trevor Day]

Without having any of my documentation (or the radio) to hand at the 
moment Glenn, I would go for the BFO frequency settings.  It is possible 
to get into this situation if they are way out.

Hope this gives you something to look at before the guys with detail 
answers finish breakfast :-)
