Re: Help with Racal-Decca
Here is an update. Thanks to your number I was able to get a guy at Sperry who worked on the RP-170 years ago, which he explained is what I have. He didn't remember too much detail and does not have any written material. He did remember enough to direct me to the various boxes in the system and pointed out that the motor control at the outside antenna is the the master and controls the panel unit motor. Armed with that info, I was able to localize the problem and although I haywired around part of the motor control, I believe I made it sweep on the bench. Now all I have to do is repair that darn motor control which has one of those problems that is hard to find without a diagram. Thanks to your Telephone number I now have a model number of the radar and an almost working system. I can't wait to finish and now I know the model number may even find someone with a manual. Thanks a lot. Ron
