OK, good to hear it wasn't local to me here. It looked like a picket
fence on my spectrum display, and I was glad when it stopped.

IARU Intruder Watch usually lists information about this signal. I believe it's regarded
as an Iranian OTHR. IW has a pretty dedicated bunch of observers around the
globe. It's interesting to see their logs of signals that intrude in our amateur bands. I
use their reports to help explain some oddities heard from time to time.ScottNM8RSent

QRN about 100 khz wide and centered at roughly28650-29000 at various times?I certainly did. A very broad,
and loud, digital-sounding signal. Myfirst guess was some sort of over the horizon radar system. Does
anyonehave any information?If it is a type of "nation-state" system, I presume it would be
verydifficult, if not impossible, to prevent it from using the amateur radiofrequencies.73,Larry
