Nico,

I had scanned the "Handbook of Bench Test and Alignment Procedure for Radio Compasses SCR-269F and SCR-269G AN/ARN-7 and AN/ARN-6" (NAVWEPS 16-30-ARN7-501) and also the SCR-269F IOM manual a number of years ago but never uploaded them anywhere. I just put them up on a Google Drive. Hopefully this provides the information you need:

Radio Compass Bench Test and Alignment Manual

Regards,

I'm working on a SCR-269 / BC-433 aircraft radio compass. This is the predesessor of the ARN-7 radio compass.
There is very little documentation to be found on the Internet for this set.
So far I have only found a wiring diagram for a dual control installation.
Anyone that has a scan of the manual for this installation? A wiring diagram for a single control installation will be of help already.

Thanks, Nico - PA3ESA
