I have not tried the Dewar or mineral oil, but I have tried putting it
inside a second oven that is set just above ambient, both a very simple home
built one using a box and a light bulb and a HP built double oven.
Both can be made to work great.

Thanks, Warren. I simply cannot remember, 'cause this is a long on-going
thread. Has anyone tried a dewar device in which the 10811 or similar is
suspended in mineral oil?

The test took a while, but I finally got around to testing the effect of
setting a HP10811's inner oven to the xtral's EXACT turn over temperature.
Short answer is NO Help.
I did not see any improvement in freq stability with environmental temperature
changes.
It did help in reducing the small

Hello group,
I like to synchronisize a fine 100MHz TCXO with the
10MHz output of the Tbold. The TCXO has a EFC input.
I know this can be done
using a PLL but I do not want to add noise
to the very good noise parameters of the TCXO
cause the 100MHz signal is to be used to clock
a FPGA which contr

I for one, like SLOW fans (as long as they are set up so WHEN the fan fails,
nothing really Bad happens)
LH's temperature controller using a small fan blowing on the Tbolt is a
great way to improve its performance.
I have found that for general cooling, 5 Volts on a small 12 V fan that is

I did follow your suggestion and installed the original ATT heat sink and

Here's the Windows shortcut that my dedicated laptop normally uses:
"C:\Program Files\Heather\heather.exe" /ip=localhost:45000 /f /vm /gm /go
/ga /T=-7PDT /y /y /x=1000 /tw=25
These options are decipherable by running heather /?, but basically, in
order of appearance, they do the following:

Good point, I did not keep a link to that article, so I can't check now but you
are most likely correct. The article made reference to an unnamed hedge fund
