[Elecraft] K3 "Donald Duck" 20 meters & above

[Don Wilhelm]

Gil,

The subject says K3, but the body of your post says K2.
If it is the *K2*, what is the possibility that you have the USB BFOs on 
the wrong sideband?   Or did you leave the internal counter probe in TP2 
as many builders do and changed the SSB filter settings inadvertently 
while working with something else in the menu?
Also note that the BFO used for USB on 15, 12, and 10 meters is the same 
as that used for LSB on the bands below 15 meters.  You said 20 meters 
and above - does that mean you were able to hear USB signals on 15, 12 
and 10 meters?  If you were unable to tune 15 meter USB stations 
correctly, but can receive LSB on the lower bands just fine, you have 
something more wrong than filter alignment - and I can't think of what 
that cause may be.

If you do have a K2 and are unsure of the filter alignment, you may want 
to check out my website www.w3fpr.com and review the article on K2 Dial 
Calibration - filter alignment is covered in part 3 of that article.
