According to Steve Cain:

"This is an Atlantic Research TMG-4 Test Message Generator I found in a dumpster today.
It is plugged straight into a 10W guitar amp.
I appoligize for the audio quality.
I did not want to risk recording gear on an initial test."

Update via Steve Cain:

"The freaky part is, the end of the second video [top video above], I had turned the amp volume all the way off. It's pumping enough juice to power the speaker anyway" ... "and they made Minuteman Missiles too." ... "Atlantic Research Corp. was a major military and NASA contractor back in the day."
