Was in the local electronics surplus store today looking for something totally non-mil related, and lo and behold I spied a RACAL 931 with battery pack and matching MA-937 vehicle power supply.
For $45 I just couldn't pass it up.

So now it's on the bench getting checked out and cleaned up. 

I'm going to need to source some of the cannon type plug connectors if anyone knows a good source.

Just a guess, but maybe a common interplane freq.? (126.18 MHz), or maybe on HF using the fundamental.  If for VHF, it would follow there be an equally common receiver mixer crystal.

I have a bunch of them around, and 7010 is quite common here as well.

With your kind indulgence,  I ask the following:

Why do we find a proliferation of surplus CR-1-A crystals cut for 7010 kHz?
