Hi=20 LF,

 

Just made an=20 interesting observation regarding QSB at=20 508KHz.

 

For my own=20 benefit I have started running a slow SpecLab showing 500 to 510KHz &=20 capturing for evaluation.

 

Occasionally the=20 NDB =93Z=94 shows up. The strange thing is that even though the carrier on 5= 08KHz=20 & the two ID offsets at 509 & 507KHz are relatively close they each=20 display at different depth of fading or an out of phase fade=20 pattern.

 

I am unsure why=20 this should be, any comments please, see capture at link=20 :-
