Send a captured snapshot using the P3 utility. On the water fall I see stations there their signal goes well past other signals. Yes, I see similar and I would call it splatter. Especially when it is clear other stations are not doing this. Over driving something past their SSB filters. On a local net where the are mixtures of vintage and modern the vintage ones ( on this net) tend to be much broader and for sure they are not over driving. 73, tom n4zpt ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
