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, have you some mains hum affecting the audio in/out of the PC?

Cheers,

John
