I refer the honourable gentleman to the report I made some time ago....
11/11/09:
=================================================================
Jim. LF
It looks like G7NKS has a 50/100Hz problem on the audio - both in TX and
RX directions - there are up to 3 decodes by Jim of a single station (eg
G3YXM), spaced by 50 & 100Hz and I see also that M0BMU is also reporting
multiple decodes of G7NKS with the same 50/100Hz spacing.
================================================================
Jim has been looking for a source of 50Hz infecting his gear - looks
like he hasn't found it yet :-)
Needless to say, at this range, I only see the main signal...
Cheers,
John

Hi Jim and LF group
Please observe the reports I am getting from Jim G7NKS WSPR
transmissions :-
First a weak one and then a strong one then a weak one (see below)
does it mean there's a sprog / modulation on Jim's transmission off
set by approximately +/-50c/s?
