Hi LF,
Just made an interesting observation
regarding QSB at 508KHz.
For my own benefit I have started running a
slow SpecLab showing 500 to 510KHz & capturing for evaluation.
Occasionally the NDB “Z” shows
up. The strange thing is that even though the carrier on 508KHz & the two
ID offsets at 509 & 507KHz are relatively close they each display at
different depth of fading or an out of phase fade pattern.
I am unsure why this should be, any
comments please, see capture at link :-
