[Elecraft] OT-P3 capture of a 17M intruder

[Richard Fjeld]

There is one that is about -70 dB at my Minnesota qth on 3.950-60 MHz (as I recall).  It is ten KHz wide with a second 10 KHz wide signal right above it in frequency, but about half as strong.  However, I have seen times when the second one wasn't present, or was being covered by other signals. 

I see it late in the evening after 10 pm cst and it lasts non-stop, with no let up, for hours.  Other people with pan-adapters have asked  about it.  It reminds me of a digital TV transmission.  It is nicely shaped and stable.

  Anyone have any ideas as to what this is?

  I have seen similar signals before, but not in the amateur bands.  Today this one marched across 17 meters.  Details in the posting.
