Some time ago I acquired a 28ASR unit from the VOA ARC in Bethany, Ohio. I now finally got some time to do some work on it and use
it with the Dovetron MPC-1000R that I also got around the same time. 

The ASR came with two, 2-wire connector cables. One is hardwired in and the second is a separate cable. I'm not sure how the second
cable was connected to the 2ASR on the inside.

I tried hooking up the hardwired cable to the Dovetron's 2-way loop jack, which was hooked up to my PC listening to ITTY. I had it
tuned in and the loop light was lit, but nothing came out on the printer. I checked and there is 60ma at the Dovetron loop jack.

The hardwired cable is connected to connectors #179 and #180 on the 'connector board' at the back of the ASR. #179 also goes over to
#2 and #180 goes to #1. #2 then goes on over #16.

The LESU (not sure which one it is as it is unmarked to what model it is), has four jacks on it labeled LJ, BJ, PJ, and RJ. Anyone
know what they are and how they are used? I can send a picture if anyone wants to try and ID it.

My Navy experience with Teletypes (1970-1979) were with the Tempest modified models, so the electronics were a lot different.
