[TenTec] Orion/O2 Drift Problem-who is interested in a fix?

[Ron Castro]

It probably wouldn't even need an OCXO, just a really stable TCXO like the 
20 MHz unit Kenwood uses.  I have one in my TS-870 and even though it does 
not run when the rig is turned off, it is still rock stable and extremely 
close on frequency.  Total warm-up drift is in the order of 1 Hz at 15 MHz.
