[Hallicrafters] Info on S-72 and S-72 L

[Vern Weiss]

Oops!
I should have got my flabby caboose up and off the sofa and went downstairs
and actually LOOKED at my S72 and S72L. For starters, I don't know where I
came up with 18 MC...must've been thinking of a Transoceanic or something.
Indeed, the S72 550 to 30 MC only. The S72L covers 175 KC to 11.5 MC only. I
believe there was also an S72R which was the same as the S72.
Sorry for the error.
