The Triad VPS12-2000 transformer seems to be the best readily available
alternative to the original wall-wart power supply so far for the ESE
ES-911/GPS/NTP. The two 6 volt windings can be strapped in parallel to
provide 4 amps. It won't fit within the 1U case so some sort of
external
OK, that makes sense. Maybe they had responsibility for keeping all their
state’s radio gear tuned up and on frequency.

Wonder why a highway department would have a rubidium standard?

Hi Dan,
This is possible with the Broadcom BCM54210SE or BCM54220SE. Ethernet PHY with
built in jitter cleaner. External loop filter, 10MHz input is possible, 125MHz
output locked to 10MHz is possible but not documented. The Ethernet PHYs will
also be locked to the 10MHz input and it has HW

... SOIC-8 is an 8 pin rather than a 6 pin package :)

Fellow time-nuts,
On friday I took the delivery of the EFOS10 maser, and this morning it
got temperature of cavity up to support masing, which is really for it
to be sufficiently in tune frequency wise, and then 2 min later the 5
MHz BVA had achieved lock on the signal. The cavity temperature
Even with a smaller device it's possible : you can sometimes
repurpose crystal and reset pins to be I/O, do a software SPI, and set
registers using write-only methods (MOSI but no MISO connection) to get
down to 2 or 3 pins used.

I think things are more powerful than you think.

You may have noticed that we recently turned off time-nuts list
'moderation'. We do this now and then. It means postings now immediately

Richard,
Faros uses a precise time of day to determine the time it took for the
beacon signal to reach your location. It uses this info to determine if the
path was the short path, or the long path.
The NCDXF beacons use a GPS receiver to determine a very accurate time of
day, and to start
