First thing to check is that it really *is* at limit. There apparently are a few odd things
that can trigger the alarm.
The OCXO’s out of the TBolt are sold on the auction sites from time to time. They
seem to go for < $40 delivered. The footprint on the OCXO is pretty standard. You
can tune the parameters on the TBolt. There are a lot of other choices. About the only
real limit is the 10 MHz frequency.
