Hi Johan,

yes, I have it. I will be happy to make a copy for you. Please give
me your address.

It's not an easy unit to operate... you need:
- a stable reference oscillator, 1, 5 or 10 MHz
- a stripchart recorder (or two, better)
- an oscilloscope (if possible a storage one, I used a Tek 7633)
- a Loran loop antenna (not E-field!!! it works, but the jitter is worse)
- an old-style Loran chain (not NELS, HI)
- time and patience to undestand operation...

The 2000C has a 3-digit GRR code, the NELS has added a digit...
so you can't sync on it. I tried to modify the logic to lock on Lessay
but without success, the timing logic is very complex and simply adding
a counter isn't enough.

So I will send you the schematic and operating manual, obtained from
Austron a few years ago. If you are able to modify it, PLEASE LET ME KNOW!
I have two units on the shelf... one paid $700... when the Mediterranean chain
was operating I was able to use the 2000C to zero-beat an HP 5061A cesium
to +/- 2 parts in 10^-12. Not so bad.
