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...
