[RFI] Impact of bandwidth when trying to analyze broadband RFI (like power line noise) using the AM audio spectrum

[Don Kirk]

As I mentioned in a recent post I have had much better success observing
the AM audio spectrum for power line RFI and other broadband noise when
using a bandwidth much wider than conventional receivers typically
provide.  I now use at least a bandwidth of 25 KHz, and prefer a bandwidth
of 100 KHz whenever possible.  I just created a simple website to show the
impact of a 5, 10, 15, 20, 25, 50, and 100 KHz bandwidth for those
interested, and here is a link to the website:

Just FYI, and 73.
