[Hammarlund] HQ180AX Mysteryn Circuit

[Peter A Markavage]

My HQ-180AX schematic does show the crystal switch, relay circuitry, and
tube  that controls this circuitry.

The offer to the group that I made last year is still open. I have excess
to my needs, the four schematics that are in the large HQ-180 Series
manual (covers the HQ-180, 180A, 180XA, and 180XE). The four 11X17
schematics are free; just send me 3 $.37 stamps or a $1 for postage in
the U. S.
