I bought a manual from them a couple of years ago but on checking their
website www.datachroninc.com it appears that the domain name is for sale.
They lasted a long time but it looks like they've gone...
Regarding IRIG, there are several different flavours - IRIG A, B, C etc all

Iain,
I own a Z3805 but have no manual for it, so the following is from my
experience only:

There seem to be 24 V versions an
There is a 44 pin chip that seems to have had a pin broken off. In my
attempts to short this to an already mangled chip socket, I managed to let
some smoke out. Oh well, now I have a pretty metal paperweight that I may
convert over to using NMEA signals from a gps.
Thanks guys,

Anyone know if there's a software control program available for the
Brandywine GPS-4 -- either through Brandywine or a third-party? Thanks!

The only jumper I could see is on the display board. It appears to just be
a segment test. I verified that it's running at 1kHz modulation against a
frequency synthesizer on the scope. Amplitudes look fine. I tried
everything from about 0.1 V peak to peak to about 5 volts peak to peak.
I'll kee
I'm 99% sure. What I see on the scope looks like what I see in the spec.
AM modulated signal, but I didn't actually verify the timings yet. I
figured that even if I was off a bit, that *something* should change on the
display. Maybe this is a poor assumption. I'm off to find a jumper...

Are you sure you are really feeding it IRIG-B? You might try looking at
your TC signal with a 'scope and seeing if it meets the IRIG spec.
Such a test would bisect the problem.
FWIW,

Hi guys,
What happened to Datachron? I'm trying to dig up a manual for an IRIG-B
display, Datachron model 3700-205 that I just picked up on eBay:

It came in today and powers up, and looks just like it does in the
pictures. Doesn't
Murray, I dont remember the detail but we used Clicklock a few time on LF
and I think Steve MacDonald VE7SL built a GUI front end to make it a bit
more appealing. He has a web site. I dont seem to have it loaded on this
machine any longer.

Hi All,
I'm thinking about adding a Z3805 to my existing Z3816 (once I get the
3816 up and running once the sparky has finished putting electricity
in the garage!)
However, I have a few questions that I need to answer before I actually
make that decision, and as I'm sure those of you who have a
Poul,
Regarding Clicklock. Yes, in a sense Clicklock is a lock-in amplifier.
However the really special thing is that it completely compensates
(within reason) for the drift in ALL the oscillators in your receiver
and/or converter, so that it becomes GPS locked. It does this by
comparing the phase
Tom and John,
I am still using my Austron loran c receiver with an austron 2110 disciplined
frequency standard. I have made several modifications as well as repairs to
both units.
I purchased the manual from Austron when they were still in business. I think
it was around $125. I looked a
Hi John;
I will see what I can do. I will also make a few additional hard
copies. It may be a week or so, Skip has a incomplete copy that I
believe it is a different REV and it would be nice to combine the two.
Does any one have a 2110C manual?

Gents,
the first users of Z38XX have found some issues with the software. I hope I
have already fixed them but I want to wait for the feedback. ASAP I will
inform you wheter the new version is free of this issues.
