I have been trying out the new AM-Sync mode by listening to WWV on its 5
frequencies and am seeing something that I wonder is a problem for my K3
(#1292) or is it being seen by others as well. I have observed that on the
10MHz WWV frequency only, that my K3 will momentarily unlock with the
This problem may (or may not) be caused by selective fading, causing the
real WWV carrier to disappear for a moment, whereby the K3 then locks
up to one of the sidebands, perhaps from the 100 Hz time data, then
returns to the main carrier when it again is strong enough. Of course
it may be
... I find it
difficult to believe that WWV is having jumps in its 10MHz transmission.
Has anyone else noticed this, or do I need to be giving Elecraft help desk a
call?
AM Synchronous receive is in its early stages. We are aware of the
behavior you describe and are improving the algorithms
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
Yes, I can clearly see this happening on my panadaptor lash-up using an
SDR and Rocky software from the IF output port of the K3. Thanks for
pointing this out. Obviously I shouldn't need to leave VFO Tracking on all
the time when receiving WWV.
