Hi Ken: I have two of these, and had the same problem some years ago (see archives time-nuts). Nothing seemed to need this frequency. Fast forward to present. I'm using an ICOM 260A 2m all-mode xceiver for if in a 13 cm moonbounce system. The xtal frequency for the basic synthesizer in these units is 5.12 MHz. I played around with the idea of separate better xtals, until one day I was cleaning out. DOH! I now have a use for those weird OCXO's! Soooooo... never throw anything away, and never dismay, for all weird stuff WILL be useful someday. There's a coarse adjustment of some kind on these units. 73, Don AJ7LL
