Hi all thank you I have now printed out the dater sheets for
The ICS570BNB3N502 ICS 512
These are all new to me so my next question are there any PCB's available
for any of the above
For best timing work should I go for Sq wave or sine wave output and out of
the 3 is
Hi all I have been told the Racal 9475 Rubidium is an entry level Rubidium
So what do you advise as my next Rubidium?
How much will it cost ?
And what will be the advantages ?

The NB3N502 is nice, I've used it to provide external references to test gear
that wasn't otherwise set up for it, and there's quite a few online references
to projects that make use of it.

You might look at the NB3N502 PLL mult chip. I've used this chip on my
rubidium
Thanks to all who responded, on and off the list. I have some homework
to do.

John,
Yes, I have a polyphaser in line.
Currently the antenna run is long, and I think it's the inductive pickup
from nearby strikes or cloud to cloud that's popping the antennas. I'm
looking at shortening the run. That will cost me the 360deg sky view
down to near 20deg, but at this point
Bert was looking at the ICS512 and have to agree the price is cheap. How
have you applied them. It seems really simple. Do you follow with
filtering. Looking at 5 > 10 MHz and 5 > 15...

Hello Paul,
Were you aware that there is a 25Hz phase modulation (of ±22.5°)
carrying low frequency data? Could that be messing up your locking?
The National Physical Laboratory here in England monitors the signal,
and publishes a bulletin every month with their measurements. This is
Paul, NPL are the sponsor of the Droitwich standard.
See https://www.npl.co.uk/products-services/time-frequency/gps-bulletins
I have not used Droitwich for some time now, but It should be better than
you quote. NPL bulletins used to quote it at parts in 10^11. That is a long
term daytime
Hi
regarding the 198 Khz reference in the UK can any one in the
