Re: [IRCA] Broadband noise - (Getting rid of it)

["Rene Tetro" <rtetro@xxxxxxxxx>]

I can't conceive of a filter that would work on IBOC (on adjacent
channels).  Since the passband of the IBOC information is 8-15khz
removed from the carrier, there is really no way that I know of to
filter out IBOC data on, say, 620 from an IBOC station on 610.  I've
tried it on several receivers like my Watkins-Johnson HF-1000 whose DSP
is capable of some pretty narrow bandwidths; same on my TS2000 and IC781
with their RIT and notching.

Powerline noise maybe? I do know there are filters available to put
right at your mains box to kill noise coming in. They are supposed to
work anyway.
I doubt this would work against something like IBOC.
