Trying to listen to TEB but there is like a talk show in the background.

Thanks!

Yes, we know.  The radio station is getting into a bunch of things at this house.  We've tried numerous types of filtering and may have to switch computers.

So...cope with it for now.  Besides, it's something else to listen to in between transmissions.

Or don't tune in at all.  wink

Hopefully fixed in a few weeks/months.

Dave, I live within 2 miles of high power pager transmitters and 2 FM radio broadcast transmitters . I remove all traces of the above by careful selection of fixed bandpass and tunable notch filters located at the receiver end.
The pager transmitters at rx frequency  were 5/9 at receiver end WITHOUT any antenna! The pager rx would 'pull' the FM broadcast rx into the am band (before filtering) .
Sorry , I guess you already know all that - thanks for the feed all the same.

I am trying to solve this issue remotely.  It's not getting into the scanner - it is getting into the computer or the sound card.  Tried ferrites on the audio cable and a number of other things.  Unfortunately the location is *really* close to the AM transmitter.
