[time-nuts] LORAN C simulator operational

We sold a lot of 2100 series products over here when I worked for Austron. A
number were used up in Norway on Oil rigs as part of their telecom sync
systems. Also sold systems into Germany and France. I know this is back in
the mid/late 80's, but may be helpful.

I just received this good news from Poul-Henning Kamp:

=====

If you want the GRIs in microseconds, add a zero:

67310, 74990, 70010 and 90070

My 2100F had no issues with them.

=====

That's great news for me, if the signal is strong enough.
