[Milsurplus] Looking for a some crystals

Good morning all,

I am looking for some FT-241 crystals, specifically
marked for channel 873 (87.3MC) or channel 882 (88.2MC),
but I will take anything in the channel 870 or 880 range.

These crystals were used in the transmitter for the
AN/TRC-1. However, I have another use in mind.

I am firing up an AN/VRC-2, and it appears that these
crystals might be usable in the VRC-2. 88.2 Mc
divided by three is 29.4, and sure enough, for these
frequencies, the fundamental crystal frequency is the same.
The VRC-2 multiplies by 32, the TRC-1 multiplies by 96.

Just curious if anyone has any of these in their
stash o'stuff.

The receiver for the VRC-2 uses the same crystal formula
as the BC-659 and BC-1335, and those crystals do work in
the R-237/VRC receiver. The receiver is playing, I'm now
starting to work on the transmitter.

Thanks.
