I've noticed on strong sigs from me (few and far between!) I get multiple decodes +50 and -50. I'm not aware of any obvious mains hum if I monitor my outgoing sigs and all leads are wound on ferrite cores, but clearly something is amiss. I shall look into it and see what I can find Cheers for the heads up With best regards Jim Dr. James Cowburn -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org] On Behalf Of John P-G Sent: 11 November 2009 23:24 To: rsgb_lf_group@blacksheep.org Subject: LF: G7NKS multiple WSPR decodes! 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 GM4SLV
