Hello Mike,

Thanks for going through the hassle of scanning and the OCR process on the
UR's. Great stuff indeed.

Thanks again,

One of the least exploited document sources of WWII aircraft equipment 
is the set of maintenance digests for Navy and USAAF radio equipment.  I 
have finally finished OCR-ing one of the USAAF  "Unsatisfactory Report" 
digests (from May-June 1944) and it has a page which mentions the 
BC-706A and SA-3/A crash switches.  See 
http://aafradio.org/docs/docs.html under "Operational Notes" for the 
whole radio section of the document - the crash switch is mentioned on 
page 35R.  Originally set for 10Gs, the springs evidently weakened over 
time to start giving problems with hard landings and turbulence...  :-)  

The UR's (and the Navy equivalent Airborne Radio Maintenance Notes - 
ARMN) provide a fascinating snapshot of problems reported from the field 
on various types of radio equipment.  Please let me know if there are 
errors in the OCR version of the UR - it has cost me countless hours 
correcting format and words, so there are more than likely many mistakes 
in it.  I have sworn off OCR until I find a better software package.
