What I do get sick and tired of is other hams who have had bad experiences with a few cheaply made homeplug copies who think that there should be a blanket ban on all other technology just because they have a radio licence by answering a load of multiple choice questions and then seem to spam all the radio ham forums to that extent..

Reminds me of the days when hams where up in arms about RTTY, then AMTOR, then Packet and most recently APRS
I do see your point, and there is a place for this type of technology, if used properly. There are also a great many people with Amateur licenses that IMHO opinion didn't ought to have them!

Some of the power line networking devices I have seem have been notched, and the notching is pretty good too, where it's used. Unfortunately there are a lot of the cheaper badly made units out there that don't bother with this.

Somehow I don't think your interference problem was the same as mine, as mine was still there at an S3 with no antenna plugged in. Yours sound more as if if was some sort of pick up issue on the shield of your co-ax. I had a non-amateur I know come round here with a spectrum analyser, his words were along the lines of "the only way you'll shift that is by getting the thing turned off".

BTW, what are people moaning about APRS for? Great mode if used properly for what it's designed for.
