Joe,
You've probably already thought of this, but you can feed an external 10 MHz
reference into the back of your 1200. GPS and rubidium references are
pretty affordable these days. Scrounging them from retired cell site or
paging stations is even cheaper. An external rubidium or GPS reference may
render the 1200 less mobile than it was stock, but it's better than using it
as a door stop...
Worst-case, get a good 10 MHz OCXO module off eBay for $50. Who knows, you
might get lucky and be able to find something that you can graft into the
1200 without major surgery, or mount it in a small shielded box and attach
to the side or rear of the 1200.
