[Milsurplus] AN/PRM-31 PRC-74 Test Set

[John Watkins]

Hi, 
 
Does anyone have a schematic of this test set?  I know I am being picky, but I want to adjust the 2.0, 5.0, 8.0 and 12.0 Mhz outputs on my unit.  The first 3 are almost 100 Hz high while the 12 Mhz freq is .5Hz off on a 10 second count with my HP 5300 counter (in calibration).  I finally have my 74C up and running and want to use the PRM-31 as a signal source for another project.  The 20P and 40P manuals don't have any schematics, and I can't seem to find a TM that does.
 
Thanks,
