One thing I want to clarify - it is not a Jupiter GPS module - it
just uses the chipset, presumably hooked up as in the application
info. The board is proprietary, and there seems to be no standard
electrical or operational interface as would be expected in an OEM
GPS module. So, the only way

Are you using cross-correlation?

Actually, the core saturation depends on how much voltage is applied
at a given frequency. Most power transformers are run partly into
saturation at rated line, to get the most from the copper and iron
available, in exchange for heat and less efficiency. The magnetizing

Hi
At the moment Comcast and ko4bb.com don’t seem to like each other. I can’t
refer directly to the schematic or the page.
What you *should* have (assuming 10 MHz inputs for clarity):
1) The RF inputs go into the mixer from what ever sources you happen to want to
test. At least one source
Loic,
If you have a single-pole low-pass filter at say 20 kHz you will have a
60 dB damping as you hit 20 MHz. No reason to get really fancy.
Either just do a two-pole low-pass filter (inductance, capacitance) or a
two-stage RC-link, or consider doing a LC-series link between signal and

Bob,
It may not have been Comcast. I had issues (cockpit error on my part) with
the server this morning around the time you wrote your message. It should
be OK now.
However, the new setup is making it more difficult to attach links to
documents because when you click on a document in the Manuals
Folks,
a new GUI installer with ntp-4.2.8 for Windows is now available at
Meinberg's NTP download page:
http://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable
This also includes the current version v1.0.1j of the openSSL DLL, which
also fixes some openSSL vulnerabilities.

Ed,
Not 100% sure this is the same model, but it would seem to indicate there's a
PPS signal on the DCD pin (from the gpsd-users list circa 2007):

Have a 'scope to check what that pin looks like?
