what are those jet-engine type sounds i hear on certain frequencies?
it's not static, it's a tuned signal, but sounds like a jet engine.
thanks.

If you are on AM BCB, that would be IBOC. Of course, now we are going
to hear from you know who!

In the SF bay area, Clear Channel runs their IBOC at night. Also
another station that I don't recall the callsign because I don't
listen to it. It's near KNX.

I noticed KGO hasn't been running their IBOC during the day.


KNX1070!!!

LA News

I listen to it on the computer.

If you're talking about in the international shortwave bands, it could
be jamming, birdies, facsimile or any number of things, but if it's in
the AMBCB it's likely the IBOC-HD component of an adjacent station.

Still waiting for him to post some frequencies so that one might check it out...

TKinLA,

"Jet Engines" Sounds are usually described as having
a High Whine and Loud Roar.

The more common "Aircraft Engine" {Airplane} Sounds
that Radio Listeners say that they Hear are more like
the Sounds coming from a Propeller {Prop} Engine with
a Medium Pitch with Constant Noise and may be some
Thumping {low level sound modulation}.

-IF- These Sounds are Sharply On-Frequency +-5 kHz
they can be some from of Non-Voice/Music Transmission
or possibly Radio Jamming of that Broadcast Frequency.
http://en.wikipedia.org/wiki/Radio_jamming
http://en.wikipedia.org/wiki/Radio_jamming_in_Korea

"Digital Hash" Sound is more of a 'White Noise' Sound
is a Constant Across the Spectrum High Noise Level
which extends for 20 kHz or more around any frequency.
http://en.wikipedia.org/wiki/White_noise

To me the Chinese Opera Music being Broadcast by China
Radio International (CRI) from China (PRC) on Shortwave
was a form of Jamming.
