The WSPR signal has a bandwidth of around 6Hz, so the problem is finding that much of a gap between lines. E.g. with the Northeastern USA chain with 9960 GRI, lines should appear every 5.02Hz roughly, although I expect some will probably be stronger than others. Can you look with Argo on a wider setting to see if there are any 6Hz wide spaces, or at least areas where the lines are weaker? Vernon - I'm afraid "SCP/LN8PHG" probably isn't a genuine signal, but WSPR producing a false decode - this is fairly common when narrow-band QRM is present, although only occurs rarely when just the band noise is present. Because of the way WSPR encodes/decodes, it will usually try to format any "gobbledygook" as a legitimate message with callsigns, reports, etc. You can usually tell by the outlandish callsigns and locators. A pity really, otherwise they would be pretty impressive DX! Cheers, Jim Moritz 73 de M0BMU
