What is 'bubble jamming'?

It's jamming that sounds much like water boiling in a pot.

I think I know what you mean.
Sounds a little like mfsk too, doesn't it.
I think I have heard that at 17720.
I wonder who is doing that these days.

I get Cuba bubble jamming Radio Marti and China opera jamming the VOA
every day many frequencies day and night. The continental USA gets it
both ways.

Bubble jamming sounds like the noise you get blowing into one of those
pipes to make soap bubbles.

Or blowing them spit bubbles with your lips.

Well, CODARs typically use 150 kHz or so.
That makes them kind of obnoxious.

Horrendously obnoxious.


DRM isn't typically a wide signal, is it?
Typically it is no wider than a normal AM
signal, right?

http://www.drm.org/system/technicalaspect.php

So it can be 5 to 20 kHz wide.
i.e. up to 4 standard AM broadcast channels.


I can't say I've heard many DRM signals
on shortwave. There is one local MW AM
station that appears to be using it.
At what freq is there a regular DRM broadcast on
SW?

schedule at http://www.drm.org/livebroadcast/livebroadcast.php

Hmm. Not to many of them are good prospects to be
received in southern California.

I'm hearing something like a DRM at 2723 kHz now,
utc 2006/01/15 0414. About equal in strength with the
general S2 noise.

Thanks for the links.
