Hello,
I am a new subscriber to the list ! I am located in France and I play with
time and frequency instruments on my free time.
Recently I've bought an used FS725 unit with a PRS10 oscillator in it. I
was wondering how can I estimated the age of the Rubidium oscillator. I
think the age is relat
course :-)
Many thanks, in advance, for your efforts.

Paul,G8GJA

Thanks for the link I downloaded the manual and it all makes sense now.
Yes just lift the inductors to clear the DC. Its is actually for line
powered amplifiers as someone mentioned.
You would of thought there would be a power jumper per BNC.
Good luck.

Congrats and have fun. I think the darn clocks go for as much as Doug is

picked up my 2nd 5061.

Classic sign of bad electrolytics.

With some humor as I looked inside my egg I had replaced the caps also. So
it is a common failure.
Also note the chip is not a micro but an array or at least a state machine.

No RS 232 apparent and I have not gone inside to look. Maybe later today.
But believe as others this is sort of pre-rs-232. Also no apparent EFC
control.

It did make it to the post.
Question. Rise and fall times are sub 40ps is that a typo in your email.

this if the lamp lights and the system can be
recovered. Just something to know about. I have done this several times on
different FRS units.
Wow now you have 2 5065s. Nice.

I would simply slap a 741 into position to see how it behaves.
Also check those zeners for +/- 14.7V. They go bad.

I had no idea that you had done this work.
Pretty interesting. Amazing amount of weight and the fact that it ran for
some 134 days.
Thanks for sharing.

Interesting on the water fall.
To reverse the offsets.
Take the difference of the frequency from the supposed center frequency.
Then add it to to the supposed center frequency.
Flip this process if I have it backwards.

But its a cold RB clock and though it stable its still a secondary
reference.
Bob your right its interesting that the sales locations are in China and
India. Perhaps a larger opportunity for a RB reference today.

comment makes sense on the 90 degrees. I can see how that math would
get tricky and its a general use-case that most likely someone said so

On the north pole in an aircraft you would most likely rarely ever be
exactly at that point and in a plane it would not be all that long.

This was referred to in my post (subject: 'Loran') on 8/8/17 and was a news
item in 'Inside GNSS' and other journals before that. Didn't get many comments
on my post :-(
Must have used the wrong subject

From: time-nu
added an amplifier to correct for the 16 db of loss in the 8 port
splitter.
Most modern antennas have quite a bit of gain so with good feed line (I use
1/2" hardline) You may not need the amplifier.
I am quite interested in your blitzertung perhaps we could correspond
directly.
