I am replying from this email address just to see if this will
eliminate the strange
formatting the list server applies to my messages.

Too bad, I was going to suggest gravity waves and ask if the
magnitude of the oscillation changed with orientation of the
unit's case. But I'm not an astrophysicist so I don't know
the expected magnitude of the effect.
maybe the gravity waves aren't to be ruled out totally... I live
near to a
horizon of events, and this could play a role... I have to ask the
of the black hole how stable is his hole, gravity-wise :-)
Anybody know the stability of the VP Oncore GPS?
If you mean the jitter on the 1pps signal, it should be about 45 ns, 1
Alberto, what's your weather been like? Clear, windy, cloudy?
We are enjoying a nice ending of the summer season, sunny and clear
not so hot and humid as last year. So this should not be the cause any
behavior from the 10 MHz quartz...
BTW, I measured the oven current, but there is catch-22
Initially, from cold, it draws abt 740 mA. Then, when warmed, suddenly
it falls down
to 34 mA. It stays there for a minute or so, then it increases to abt
But this value is not stable, it moves slowly from abt 186.7 to abt
187.3 mA and back.
The catch-22 is that my DMM is of a simple type, no serial connection
to gather data
with the PC, so I have to be near the circuit to watch it. And of
course my presence
there perturbates the measure. When I find the time, I will run a
couple of wires outside
my cave, errr, my shack, to be able to measure the current without my
500W of radiated
power influencing it.
