Walter, Marco,

thanks for the information regarding the Austron 2000C.

I did not get the manual but, although it is an early 70's design,
there was a test protocol from Austron taped onto the box and
it was dated 1990. When did they change the repetition rate?
Could it be a modified unit? I have yet to open it up and see
what's inside.

I already have a Brooks Shera style GPS standard, which I am
quite happy with, so I don't mind if this box turns out to be a true
piece of junk. It could be put to good use as a boat anchor (literally!)
for fishing in a nearby lake, or I could use the cabinet for some
new project, hihi...

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...

I have all of the above except an old-style Loran chain :-)
