Dog's Ear Emits Radio Signals
From www.thebostonchannel.com this ABC affiliate has an intriguing video
of a Chihuahua with big ears that constanly emit an audible high-
frequency tone. Now, maybe the ears are only collecting ambient room
sounds. You be the judge.
The dog might, indeed, be demodulating a nearby (I suspect powerful)
signal source. I'd be looking nearby.
Attached are three spectrograms of the audio from the WOIO YouTube
piece. Two of them show an FSK (Frequency Shift Keying) signal that
shifts from ~5500Hz down to ~5200Hz for ~250mS. This is probably
digital data of some sort, perhaps an idle communications channel. One
of the three audio clips presented is a slightly different frequency and
I'll spend a little more time on this most interesting clip, but I'd be
looking at an RF spectrum analyzer, were I there.
In regard to this, see Objective Tinnitus at this link or elsewhere by doing a search on your own for "Objective Tinnitus" (with the quotes).
