Questions about Austron 5000 Loran C receiver
Greetings:
I think this is my first post to this reflector. I have been a subscriber
for some time now. Thanks to everyone for sharing their knowledge.
Recently, a member of this list gave me an Austron 5000 Loran C receiver.
With the recent news about Loran C, I am interested to try to use this
device. But I have some questions:
Is it possible to use this receiver without the PDP-8 computer that it was
generally paired with? If so, how is it done?
Does anyone know where a manual for this receiver can be found?
I appreciate any help.
Thanks
Andy K0AJL

Only by substituting a different computer, running a program which
controls the receiver like the PDP-8 would have done.
This may be easier than it sounds, provided you know what the heck
the PDP/8 did.
Otherwise: forget all about it.

Never attribute to malice what can adequately be explained by incompetence.
That is indeed interesting because the only rcvr I knew that needed a pdp 8
was the older actual station monitoring units.
I would strongly believe if you know what the 5000 wants these days its
very reasonable to emulate the control system.
That said in the US the only GRI I could monitor was the great lakes chain
89700.
It was on and off the air as you might expect for a test.

In case any of you have want to play with Loran-C, here is a modern
DIY computer-based DIY receiver for time-purposes:
http://phk.freebsd.dk/AducLoran/
Mouser has the "aduc7026" board for EUR62/USD76.
In addition to that you need a 42MHz clock (I use the TAPR PLL
board) and a random transformer to attach your antenna.
Here is a time-lapse gif with a nights worth of loran-C:

Have fun...

SIMH among several other simulators could be used, provided you have the
program.

It's resonable that the PDP-8/E did the hyperbolic stuff for navigation.

Hi, I used to work for Austron, but I don't remember a 5000. All their
receivers were 2xxx series (2000C, 22100F etc).
Can you send me a photo?

Hi
Page 18 here : http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA337399
Gives a pretty good idea of what a 5000 is. Simple answer- it's a front end and all the work is done in the PDP-8. I think PHK's gizmo would be the better bet to get something running easily.
I might even go dust off a 2100F that somebody from Austron sold me back in 1983. It's still got the "demo unit" stickers on it..

Top of page 63 (page 65 in PDF).
You see the actual receiver on top of the PDP-8/E. The question is if
you have the full set or not.
It is actually a digital receiver where each of the 8 channels samples 3
samples with 12 bits, timed appropriately. The PDP-8 then do the channel
tracking loops and other calculations.
There's a lot of Loran-C stuff out there.
I didn't managed to find a Austron 5000 manual, but it would be fun to
find it.
Cheers,
Magnus
Hi again: Thanks for all of the replies so far.
I took a few photos of the unit for Mr. Kimberely. They are a front view, a
rear view and one of the label on the side. Not the greatest shots, but you
can view them here:
https://plus.google.com/photos/110810019489830210559/albums/5715752440279697361?authkey=CM2uhYmH7PnfmgE
As you'll see, interfacing it to something doesn't appear to be simple.
However, I'll look into the emulator links. I appreciate them.
I do not have the full set- only the receiver part. Every online image I
have found looks like it's sitting on the PDP-8

Does anybody have any info on the 2100C receiver. I have one that somebody
gave away, mistaking the listing for a 2100F.
Thanks,
