For sometime now I have always wondered what that dang beep beep beep followed by a machine gun sound of different tones. It's usually found above channel 40 (27.405) and LSB from what I can tell.

I have no idea but I hear it often throughout the "Freeband".

See if you can recored it and post it...
 
Does it sound like trunked transmissions on a scanner... when you don't have a trunk decoder?
I'm not sure what trunked sounds like. Don't have a scanner. All u know is that I have heard it in several freqs above channel 40 and its intermittent all day long every day. Beep Beep beep dadadadadadadadadada. Beep beep beep blahhhhhhhhhhh. Then might go silent for sevreal min then back again.

All I know. Sorry typo
 
Google says it Iran doing it on 27 and 28 Mhz.

Technologically, OTH radar is a very nifty concept. It involves bouncing extremely powerful radio signals off the ionosphere. Signals bouncing back are analyzed using sophisticated computer software, producing real-time data on the positions of moving aircraft and ships within 3 000 kilometres of the radar’s location..

So that is almost the most annoying crap on the band. (Notice I say ALMOST as I'd rather listen to that than some of the ops....but I digress) I guess they figure its "OK" disrupt a band that is not officially "occupied" by operators?? I guess our little stations must not interfere with their extremely powerful systems??

Maybe we should file a complaint with the FCC? (Yeah right)

It's not just your little CB band being interfered with by OTH radar and I highly doubt it is Iran. OTH radar has been all over the HF spectrum the last couple years after being on hiatus for a loooong while. It started back in the late '60's IIRC and a lot of us remember the Russians and their "Woodpecker" in the mid/late '70's and '80's. The biggest offender today seems to be China however OTH radar is operated by several nations including China, Russia, Australia, France, and the USA.

Forgot to add;as far as complaining to the FCC it won't work. The FCC is internal to the USA and has ZERO jurisdiction outside those borders.
Complaining to the FCC? Surely I jest ! Oh...and thanks for letting us know that our "Little CB Band" isn't the only one being disturbed. Of course us little people wouldn't know the rest of the spectrum is being disturbed.
