Thanks to Bill and Mike for the very helpful info!
Unfortunately, doing warm reset, cold reset, factory reset, multiple
self surveys did not solve the problem.
Forcing Disciplining to Enabled did not help.
Tuning the oscillator did not help.
I can manually control the DAC voltage using appropriate commands and
the 10 MHz output changes appropriately following each manual command.
But the DAC voltage doesn't respond to GPS input.
I note from my old records that when the unit is working properly and
the DAC IS being controlled by the GPS, Lady Heather still says "Doing
fixes", because fixes are in fact being done. But when Lady Heather is
working properly, she says that the Discipline mode is "Normal" instead
of "Power-Up" as she does now.
I used TBoltMon.exe to see if I could get any more info on the problem.
In TBoltMon.exe's GUI under "Disciplining Status" Mode is listed as "(1)
Power-up" and Activity is listed as "(1) Osc Warm-up".
So I wondered if the problem is that the Thunderbolt thinks that the
oscillator has not warmed up and therefore won't come out of Power-Up
mode. But the manual says that the Tunderbolt won't start acquiring
satellites and do the self survey until it has warmed up. And the
situation is that it has acquired satellites and it has done the self
survey, both of which would suggest that it thinks that the oscillator
HAS warmed up. The the TBoltMon reading on the oscillator status seems
to be inconsistent with how the Thunderbolt is performing; it is acting
like the oscillator IS warmed up, at least in some respects.
Are there any schematics or diagrams or service manuals available for
the Thunderbolt? I couldn't find any with Google.
Thanks again to Bill and Mike and all for your help!

HI All,
I am wondering if I have set up my Trimble Thunderbolt wrong.
I have corrected for roll-over and everything looks good in Lady
Heather but the Thunderbolt stays in Power-up mode according to Lady
Heather, and is always "doing fixes" even though I have entered the
lat and lon for a fixed location.
According to Lady Heather Disciplining is OK, and of course the log
reflects this as well
#! new minor alarm state 0800: Tracking sats Discipline OK : at
tow 235167
You can see the situation from this screen grab of Lady Heather:

Have I done something wrong in configuration, or is this consistent
Power-up mode and "doing fixes" notation the expected behavior?
I am using the Thunderbolt as at 10 MHz source for my microwave station.
Thanks in advance and 73,
