It's exactly what it reminded me of when I heard it!
Can it be caused by someone leaving their mike 'keyed up' i.e. some sort of feedback? It's just that it almosts seems to follow some sort of
pattern though if you keep listening to it... most odd..
Don't know what that is. Been tuning through the ether for years but never heard anything like that before. Certainly nothing like the usual pops
and whistles associated with the HF bands.
Just tuned in my Yaesu VR5000 and can hear it too.... time is currently 12:25GMT.
At least you know it's not a locally generated signal (unless you are a neighbour )
I've heard this before... it's not realy common... but it happens.
A ham radio operator has an open mike by accident... something may have fallen on the ptt button and we hear some minor feedback with his nearby
headphones. Feedback ends up sounding very odd on SSB.
It could be another similar accident from an operator on these frequencies... or a harmonic from a dirty ham transmitter on 15 meters. It's been 22
years since I was last transmitting... was a bit fuzzy on the frequencies.
The sound is exactly like open mike feedback I've heard before on HF SSB.
i hear static in there .i hear an meteor sound at the start.there was some solar flare activity from the sun this week.it could be coming from our own
solar system.one of the planets could be giving off sound waves. i think it would be a satellite giving off tones.might be a bad sat.
Darn - I have to admit I am dissapointed by the logical explainations we have gotten -- I was kind of hoping for the whale song like the Star Trek
Movie especially after the discussion on Fragile Earth (I think) awhile ago about the lone whale that is different from all other whales.
