[Milsurplus] HELP ON FILTER

[W7QHO@aol.com]

Norm,

This is the filter box installed on my PE-162-B.    The 162 is a compact, 
lightweight portable MG set consisting of   gasoline engine GE-12-D (two 
cycle) and generator GN-50-A.   Delivers 6.2 and 500 vdc at 150 watts.   In 
addition to the GRC-9, my manual (TM 11-971, July 45) lists the SCR-284-A, 
SCR-694-C, AN/TRC-2 and AN/TRC-2-A for use with this MG set.

My manual actually lists filter box FL-43A for use with this MG set and that 
box included a connector for use with the SCR-284.   However, my set has the 
F-147U box installed which does not have this connector.   I have a 
refurbished unit and replacement of the original filter box may have been 
done as part of this process.

I can provide you with a schematic of the FL-43A which appears to be the same 
as the 147U box except for the SCR-284 connector.   However, I operate my 
GRC-9s extensively with the dynamotor and AC supplies and have never 
experienced a hash or other noise problem with these supplies.   You really 
shouldn't need the147U or 43A boxes unless you are running the MG set.
