[ARC5] SCR-269 / BC-433 radio compass documentation

[W0KPX]

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:
