[amsat-bb] Re: RFI identification

[Bruce Robertson]

If you're sure it's not principally your computer that's causing the
problem, you might be interested in the bandsweep tool that's part of
recent builds of HamRadioDeluxe. This was mentioned in a recent
article in the Amsat Journal (I'm sorry, I forget the author), and I
tried it out a couple of nights ago. For me, the visual information
provided by that made it much easier to rotate my 2m beam and get a
heading on some RFI that I've been struggling with for a long time.
With it, you can also identify the birdies that might be signatures of
different sources of RFI.
