[CQ-Contest] Hy-Gain DRC-1 manual needed

[W0UN -- John Brosnahan]

Hy-Gain DRC-1 manual needed

I have checked the usual suspects (Hy-Gain/MFJ + Bama + lots of 
Google) and have
had no luck, so I thought I would try this reservoir of information.

I need the manual for the rack-mount, digital-readout, rotator 
control unit for the
Hy-Gain 3501BA rotator.   This is NOT the DCU-1 for the 
Ham-IV/Tail-Twister series.
And this rotator is the chain drive unit often used to rotate Big Berthas.

This unit controls the rotator over a 2-wire system and is a standard 
3.5 inch rack
unit about 10 inches deep and contains an optical encoder for the 
direction setting.

ANY help will be greatly appreciated.

Thanks  --  John  W0UN
