[Hallicrafters] Head Scratcher

[Gerry Steffens]

X meant crystal as in Xtal calibrator and as in the SX-17 with the =
crystal
filter and the S-17 without.  The SX-4 as the first Halli with a crystal
filter first made in 1934.

I don't know of the S origin.

stations from the station you want to listen too. I believe the SX 71 =

the first to have this designation.
