Not knowing all the particulars and requirements, I may be off base, but instead of spending money trying to frequency stabilize a 20+ year old radio (HF-80), wouldn't it make more sense to spend it on a modern, inexpensive HF rig? You can even get a TCXO option for some rigs. This should be stable enough for most common HF data protocols.
I assume that this is for Amateur use? If not, then my comments may not apply.
