Hi Tony: The bubbling sound I hear, only happens on the 10 & 11 meter
band.
(Analog). It is at random.

Someone once refer to this bubbling as a whale fart.

I think you're hearing Over-The-Horizon Radar (OTHR). It is a very
flatulent signal that I once heard a guy on a fishing boat refer to as
"gorilla farts."

Click on the OTHR link and see if it's the same one.
