Walter,
Are there manuals for these? I have a Trak 8390 and would like to
get a manual (or copy).
Thanks,
Mike Blazer

Good catch. Man that copy and paste really nailed me.
I grabbed the original wwvb rcvr. Appears another piece is missing. Thats
pin 1 is the 3.3V in.

Walter,
If the two datachron units and the datum 9300 are still available, I would be
most interested.
Thanks!

Hi
You can spend *way* to much time analyzing these gizmos. The simple approach is
(almost) always better:
1) How much room do I have?
2) How high can I get it?
3) What sort of coil form is available cheap?
4) How much inductance is in a few turns?
5) What frequency(s) am I interested in?
Simp
It seems like the 65256 is the better one to pick then -- newest
datecode (at least in the photos), and I can actually find pinouts for it.
The 34310 C1s have apparently been scalped from old Thunderbolts and
carry 2002 datecodes.
The 49423 on sale is apparently 2005-dated, but I can't find a
I have made a similar coil--antenna with remote fine tuning --no
mechanical components, everything is going trough the coax cable

Loops are a joy. No counterpoise and no worrying about ground/earth

looking for 6m or UHF.

Some of the broadcast oscilators for TV transmitters were pricey. The oscilator
manufacture wanted $980 to replace a bad unit. The transmitter manufacture
wanted $1800 for the same unit.
They are not true Time Nut quality but I've used them as a reality check when
trying to figure out what is

Bob,
It's always a good sign (being a time nut) to wonder if anything around you can
make a frequency standard.
I myself always wonder how close to UTC stop lights are synchronized in time,
or what the frequency or ADEV of a car's turn signal is, or how to measure the
beat note of two or more
How does the 3.3 volts get into the Rx chip?

Fellow time-nuts,
I have a FS700 sitting here, but no antenna. There should be other
signals than LORAN-C/CHAYKA available, such as DCF77, MSF60 and the 162
kHz signal from outside Paris. It would be pretty straight-forward to
put up a frame and make a number of turns of wire, and put a low-no

I have received 2 different emails that what I published seems to have gone
out.
A 243KB PDF sent through time-nuts.
Also sent out dropbox links and indirectly it appears that works.
Would appreciate some more feedback please on how you may have obtained the

Hi All,
Was looking through my basement the other evening, and ran across an

information regarding this unit, or have used it in the past.
It's an Pti XO5009. It cam from a Harris TV transmitter exciter. I

Email is getting really annoying. Gmail makes you do a dance to get it
active again. So here is my response a second time.
The system has a RB and a fine oven osc that is disciplined to the RB in
case the RB fails. The xtals pretty nice and even though an oven draws
quite low current when warm.

Thanks as I am experiencing a gmail issue with what it considers is spam.
Like you email I am absolutely unclear as to whats getting through. Many
others are experiencing the same behavior. Its AOL or something.
Thank you for letting me know it did make it through.
