Good Morning Angus
Let me start out by saying the FE5680A project was intended for time nuts
and the unit will not be part of our bench, so the work on it is limited. As
far as Rb's are concerned our focus is on FRK and HP5065. Looking back I
would most likely not suggested it, had I known
I am sure there are others on list who follow Elektor Magazine and even perhaps
their forums but there are likely many that do not.
I stumbled across this interesting frequency standard project and thought
others might also be interested:
Hi
There is a bunch of stuff on the Wentzel site about their double wall mini-test
chambers. It’s probably the best approach to the gradient issue. You still have
a gradient around the inner chamber / box, but it’s consistent. You eliminate
the coupling of the gradient to the ambient
Hi all!
My TS 2100 reports gps engine busy all the time. Looking for the Ace III
receiver to fix it.
Thanks,

Hi
Yes, that’s one of the papers that shows their little chamber. I believe it’s
mentioned in a couple of other places. Die cast boxes work pretty well for the
enclosures. If you want to zero the gradient in the inner enclosure, put a
small fan in there. That adds it’s own issues so it’s
Hi all,
My name is Denver I am currently a freshman in college and the time bug has
struck me. I recently acquired a Lucent RFTG on ebay to have a time
standard for my lab(and yes already realize its 15MHz output but may be
able to change that and or just use the 10MHz test point from the
An interesting article much like one Bert sent me circa 1989 quite recently.
The key to these systems is that the transmitters have very good references.
In the US at least we have no requirement for that level of stability on
the MW broadcasts. Though evidently some stations are quite good. I
Denver yes indeed they do a funny dance to take the 10 Mhz and get to 15.
So you are rught unless you need 15 tapping the 10 and simply filtering and
buffering is a very fine way to go. There is a power amp on the output of
the 15 Mhz as I recall that will work fine at 10. That can then drive a

I did send the document set out twice this week and I thought it might get
through with time-nuts blessing. It didn't.
So will have to assemble an email with those that requested the
documentation and send it directly to you all.
Paul,
Me too also. I'd like a copy.

You have to log in to see all the files for the project. I am not a

Seems it is a pay to be a member sort of thing but joining as a member
gets you a subscription too.
Interesting business model.

there was an article in the January 2012issue of the elektor DCF77
locked reference, the DCF77 has very similar modulation format as the

for an AM station is strait forward at first use a narrow filter to make
sure that you have just one station and feed the filter out put into a
limiter the output of the limiter will be the carrier.

Put it on one of the free filesharing sites and post the link. I've

Although I can't see any evidence of your attachment when I check the

from the list on both occasions you sent it, unless what you're referring

Several years ago there were a number of these showing up pretty cheap
on eBay, so I bought one. As I recall there were a couple of similar
versions with some differences so take this recollection with a grain of

I did some tracing of the internals on the one I had and found the
It's unclear whether you already have an aceIII installed and believe it needs
to be replaced, or, your 2100 does not yet have a GPS receiver and you want to
do the conversion.
A good link describing one variation of the 'always busy gps' problem is
The best way to measure the frequency of an AM station is to first pass it
through a Crystal filter to strip off the modulation sidebands. After that
limiting is usually not necessary. You can do that in either TRF mode, or
in the IF of a superhet with a synthesized local oscillator.
Yes, I also have that one. It came to us through a link. I think the owner

That's an interesting looking PC board but the receiver schematic link is
dead. The front page keeps coming back up. I'm going to bookmark the page
anyway with the hope that he will fix the link in time.

Sorry if I was muddy. The TS 2100 had an ace gps receiver installed. The
antenna and tracking lights went out a week ago. Just got round to checking
what was the matter. The symptom is that the gps engine always reports busy
when checked via the front panel interface.

I don't have any problem to get the schematic, everything is accessable.
