[Spooks] What's that?

[Tom Morris]

Ahh yes, the "Whales Sound Station"... It's been suspected that these belong
to the US military. There used to be one coming from down here in South
Florida, in fact, at the US Coast Guard communications base in Richmond
Heights.

It's likely that what's going on here is that a transmitter is left running
all the time (it's stressful on large transmitters to shut down and restart
them repeatedly, ESPECIALLY if they're tube...)

The audio chain is likely a line that's not particularly well terminated,
isolated, or grounded, causing RF to leak back into the audio chain and
cause feedback.

I've seen reports that someone will occasionally transmit on these
frequencies and you hear a few moments of clear voice, followed by the
feedback starting again. I've heard rather distorted voices, probably from
co-sited transmitters leaking back into that audio chain.

Whatever it is, it's not quite up to the finest standards of broadcast and
communications engineering. :D
