Sounds like the tbolt is not getting the queries from the pc and therefore
the responses are absent, but the pc is getting the unsolicited info from
the tbolt. A fault with pin 3 on the DE9 would do it, or something deeper
that kills the pc-to-tbolt comms.

I had a similar (but probably worse) failure of one of my Tbolt's. When I
went back to turn it back on, there was no response on the software.
Everything was a 'question'. The 10 MHz output was there but it never
'locked' as compared to my other GPSDO's (although it was EXTREMELY close)
and there

Thanks,
Those are not the ones.
The Isotemp OCXO36-54M is approx 2" X 2" X5" with an octal base.

Hi,
Yes, I can see alarm status and changes when unplugging antenna etc.
As mentioned the unit actually works, just no data certain displayed.

My BAD ! I got as far as the word ISOTEMP and failed to pay attention to the

Hi Joe,
When you preheat to 105C, you don't need to travel as far to
reach the melting point of the solder as you do from room
temperature (25C). That makes a big difference in how much
power you need to couple into the joint to make it melt.
If you go straight to the torch, and use the brute fo

Hi,
I bought an Isotemp OCXO36-54M a couple years ago on eBay and used it
for a short while.
I wanted to run some tests on it but I can't find the pinout!
Can anyone help?
Much Appreciated!

Did you select the right comm port? I power mine off a lot and it has always
come back.

Hi Joe,
Nope, Magnus is talking about foam insulated hermetically sealed
ocxo's.
The point you are missing is the preheater is only set for a temperature
that the foam, etc. can take on a continuous basis... such as +105C.
This preheat reduces the amount of additional heat that must be added

Hi group,
A strange situation has led me to ask a question about the Tbolt GPSDO
and the Trimble Thunderbolt monitor s/w version 2.6.
While re-arrangement of the shack, it's been idle for 3 weeks, Tbolt
turned off. After turning the unit on and letting it settle some 2 hour,

Hi!
I have been quite surprised to see the abbreviation OADEV appear. I
assume that this means Overlapped Allan Deviation, but this is confusing
since the Allan Deviation estimates already is overlapping. However, I
have seen that some use a non-overlapping estimator, but this type of

Hi, Wasn't following this one "real-time" but there is a useful trick used on
aircraft instruments wit soldered cases. They put a ring of tinned copper wire
in the joint before they solder it, leaving a "tail" sticking out. Next time
you want to open it, you just pull the wire out (cold) and it
