All,
I am looking for a manual for a Datum Synchronized Generator Model 9390. I
have one that is working, and driving a slave display, but I'd like to know
more about it.
Note, this is a 3-rack unit IRIG TC generator/regenerator that looks to be
mid 1970s vintage, judging from the
In the last few years, I've obtained 3 FRK's and all 3 had the same issue.
The C-field voltage was so far off from where it needed to be that the servo
loop wouldn't lock up. In all 3 cases, I was able to get them working by
changing out resistors R17 and R20 in the C-field circuit on the power
Ray,
I'll answer your question as I've done this. The d-psk-r's intended use is
to remove the bpsk from the WWVB carrier for the purpose of allowing older
WWVB receivers to recover phase info from the carrier and it works very well
for that purpose. But, it can also be used, as you are trying
What type of antenna are you using to receive Wildwood Loran?

Hey Ray,
Paul and I have a nice piece of code that generates the WWVB BPSK bit stream
using an Arduino and a ublox GPS module. (total cost under $30) You could
use this as a WWVB emulator while you're working on your code. Sorry, I
can't really help with your question about demodulating the
To provide some perspective. I paid $180 for an HP-5372a 2 years ago. All
it needed was the battery replacement and a bit of work on the OCXO. I
picked it up at a hamfest so there was no shipping cost. Still working
perfectly 2 years later and stays on almost 24 hrs/day.

Tom,
Thanks for the explanation of clock ensembles. That answered a few
questions I've had for a while.
Regarding your comments on collecting raw time data from GPS and post
processing it. Can you provide any reference info, links, etc. with more
detail on that topic?
Clearly I'd need a GPS
and frequency measurement

Hello List,
I am looking for the manual for a Leitch CSD-5300 master clock. These were
used in the broadcast industry in the 80s and 90s. There is a related white
paper on the internet titled "A Telephone-Based Time Dissemination System"
with a filename of ADA499239.pdf that describes the
