[Milsurplus] SCR-508 (BC-603/BC-604)

[Bob Wilder]

Has anyone have a modification for the above equipment which will
change it from WBFM to NBFM operation.  I seem to remember there was a
mode back in 1948-49 that did this but have no idea where to look for
it.  The LST-325 has some of this gear and would like to actually put
it on the air.  The mod can NOT destroy the gear as this is classic
WW2 stuff and we want it to remain original.  Shoud be no more than
changing a couple of capacitors and/or resistors and retune coils to
get it to work NBFM above 29Mcs.

TIA
