Just a heads up, in case you’re not concious of the fact; at least my HP
splitter (can’t recall model# off hand) is strictly L1 - many others are wide
band and will allow L2 and whatever else you might later want.

Here is a pretty good paper (as far as I can tell) from 2017 looking at ways to
improve single frequency results:

Depending on the receiver, the manufacturer usually provides a conversion
utility.
No such thing as a RINEX «stream» though, as far as I know. The observations
are usually collected in a vendor specific (or sometimes neutral, like BINEX)
format, and then converted to RINEX in batch.

I guess everyone has seen this, but Linear has a nice appnote «A Standards Lab

Hi, Dana.

EFOS was a series of masers made by Oscilloquartz in Switzerland, there is a
little information on my website www.efos3.com under «about».
The manuals for those masers are also available, lots of good info for the
interested:
Pat,
I am not a ham, but would be interested in participating if there is someone in
my neck of the woods that needs access to timing gear. I am in western norway,
near stavanger. I have a hydrogen maser and many other precision oscillators.

A little of the thinking, and a bit of the history of the rb v cs is in "CESIUM

That IS interesting.. It reads to me that the advice is to keep a "moving 300
pt ADEV" when continously monitoring a (pair of) frequency source in e.g a VLBI
site - the reason for limiting it to 300 pts being that much more than that is
likely to average out potential issues..

I recently also searched for details on a Micro Pulse antenna - I finally got a
datasheet from PCTEL support, who (presumably) took over the Micro Pulse range
at some point.
