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. --- Jeff WN3A
