Hi Sheldon and group:

Ahhh, now I recognize the radio. The BC-746 part threw me as I couldn't
find a reference in my usual places. I had known of the BC-745 and SCR-511
numbers from pictures and ads from the surplus outfits in old-time
magazines. "Pogo Stick" was the moniker the ads seemed to most often attach
to them. Seems Fair used to sell them years ago. Can't quite recall for
sure though.

Handy way to tell which channel. Evidently, only 14 channels were used as
the space on the label has room for 14 "bumps".

Thanks for the information and help in ID'ing these TU's. Another gentleman
from one of these lists bought the lot.

Regards,  Chris
