Re: [RFI] RFI on 1.8 mhz

["KD7JYK DM09" <kd7jyk@earthlink.net>]

"but does it have to be on a specific frequency or range of frequencies??"

Usually not.  When tracking RFI, we hear it because it's broadband an 
interfering with most everything else we want to listen to or do.  The sound 
is unique enough, the range is wide, if it wasn't, it wouldn't be a problem. 
Power lines for example.  Unique sound, RFI from 60Hz to microwave.
