[Milsurplus] WWII Crystal Confusion

[D C Macdonald]

I was speaking more in reference to
the actual crystal itself, not the holder.
I guess accuracy probably wasn't the
greatest with 100 kHz channel spacing
at the operatin frequency.

Mac,

No, the FT-241 holder is only slightly larger than FT-243.  Same pin 
diameter
& spacing (0.093" and 0.50"), about the same height and thickness and about
30% wider.  Different construction method.  The FT-241 holder was also used 
for
a 200 KC reference crystal in the ATC and AN/ART-13, the BC-652 and probably
others.  FT-241 became DC-2(*)/U.
