That's good to know. I've been running the TS2100 for a few days with a
Morian MV89A (too big to fit into the case though) and it seems to work
well, definitely more stable than the TCXO. A test that I haven't run
yet is to pull the GPS antenna and see how long the NTP server reports
Stratum 1 performance and what the dispersion values are.
You're correct about the d/a setting - it seems all you have to is set
it and it stores it in NVRAM.

I think a couple of those bits do correspond to the oscillator type installed
but I think you can ignore them. If I remember right, those oscillator bits
were only used to calculate the dispersion update for ntp packets when
flywheeling through a loss of signal. As far as I recall, you just need to
change gain and filter. And the setting for the current d/a value should have
been accessible in root tim utils as d2a.
As someone pointed out, the default ovenized for those boxes was the MTI 240
low profile.

Subject: Re: [time-nuts] Upgrading TS2100 from TCXO to OCXO
If anybody has a TS2100 that came from the factory with an OCXO, can you
telnet into the unit and run the following command?
root eng ee info
This appears to be some sort of factory-configured personality of the
board. My TS2100-GPS unit with a TCXO has an info value of 00000024. A
TS2100-IRIG unit (no GPS) with a TCXO has a value of 00000000. I'm
curious whether any of those bits correspond to the oscillator type or
if all that needs to be changed is the gain.
Thanks,
