Hi Barry,
I have just been through my extensive collection of Hammarlund literature and
the only thing I can find is reference to any calibrator accessory is the
HC-100 calibrator which is recommended for installation in HQ and SP-600
receivers. There was a particular model, number 38657-G2 for the HQ-129X and HQ-140X.
It sold for $17.95. Apparent date of manufacture was 1956.
The instructions state: ".....unsolder the two leads of the send-receive
switch and remove this switch from the front panel of the receiver. Rweplace same
with the new switch supplied with the calibrator kit, securing the new three
position plate under the nut on the front panel." The new switch is indicated
to be
"2P3T." Possibly that is your present switch and the installer didn't use the
panel. The switched lead from the XC-100 calbrator is red.
Please let us all know what you find.
73,
John, W4AWM
