[Hallicrafters] SX-42 Bandspread

[JD]

Fist of all,

Everybody welcome to my life, obviously an error, but
after all these years on this list we're all family.

Listen to Ed, he help me sort my SX-42 out once upon a
time. I opened mine up and saw that the BS cap is
un-meshed at zero, fins facing up. Turn the dial all
the way to the left and the cap meshes 1/2 way; all
the way to the right and it too meshes 1/2 way. Only
half-way in either direction.

Best of luck.
