RFI Snapshots...

[NK7Z]

I have compiled a set of snapshots of various RFI sources from a number
of folks that were kind enough to send them in to me.  They are at:

https://www.nk7z.net/rfi-snapshots/

There are close to 50 different images showing various sources there...

I am always looking for a P3 image of RFI of a KNOWN source...

Have you considered including sound clips with the snapshots as well?
Being able to see *and* hear the RFI can go a long way toward making a
positive ID. Of course, RX mode and bandwidth info would need to be
included as well.

That is a very good idea, and I have, and if I get sound with an SDR
image, I add it to the site...

As you said though, bandwidth, etc., tend to make things sound different
depending on who uploads.  The real useful thing about the spectrograms
are that they can be used as a site survey tool as well.  The snapshot
page was basically and offshoot of this page:

https://www.nk7z.net/sdr-rfi-survey-p1/

which uses an SDRPlay RSP-1 as the SDR engine for a way to characterize,
or survey your RFI environment.

I ended up with a lot of spectrograms as a result of the site survey
page, and it occurred to me they might be useful to others in IDing
RFI...  Now there are almost fifty different shots of RFI there.
