[Hallicrafters] Bumblee Caps.

[Charlie T, K3ICH]

"Some of course is just imagination. I remember 
once listening to a symphony concert, I mean live with an 
orchestra in the hall, and hearing a splice go by. What did 
my ears hear that my brain interpreted that way?"


Not sure what the proper medical term is, but it is like a mini-stroke, 
where you experience a very brief "hole" in your hearing.

Then again, it just might be your "Spider-Sense" tingling....

73, Chas
