Yes indeed lots of thinking. Thinking is good when you are paid by the hour.
Unfortunately it doesn't create an alternate time and frequency reference
should GNNS fail.
I have been following this for a long time and hope that eLoran returns. I
always enjoyed it as a reference here in Boston.

Yes, they've been switching back and forth between one or two channels all
day, with the one channel state always being just the usual Anthorn Y
channel and the two channels always being Master plus the Y channel.
Sometimes the overall signal levels have been fluctuating quite a bit at

Well this is indeed a good new year.
It would appear that Anthorn will be active for a year to 2017.
It will be dual rated as a master and slave same sight. Much like the US.
The ups and downs you are seeing are the process to dual rate the Master.
Should settle out soon as Master and Y.

In the US at least for the eastern half of the country the test station has
been on lately for several weeks at a shot. Not exactly the old days but a
great resource besides GPS to check my various references and note offsets
and such using the austrons and SRS.
I would agree 1 db difference
This could just be wishful thinking but I'm still hoping it might stay for
some time yet.
The UK General Lighthouse Authorities have been running their eLoran trials
since 2007 so perhaps they found sufficient incentive within that time to
keep going.

I'm pretty sure it was Anthorn.
It was showing as the Master and Y stations, and the individual signal
levels as indicated on an FS700 were within 1dB, which would seem a reasonable
tolerance on equal signal levels given that the FS700 only reports to the
nearest 1dB anyway:-)

I somewhat may guess its Anthorn.

The FS700 data sheet specifies the standard oscillator to be be an ovenised
oscillator using an AT cut crystal, and the option 01 oscillator to be an
ovenised oscillator using an SC cut crystal.
The SC10 data sheet specifies it to be a "10MHz high stability oscillator
using an SC cut crysta

I have a FS700 and would like a copy of the software.
I enjoyed the use of LORAN C when it existed and even in some of the test
runs.
The runs have been pretty quite or I have missed them.
But LORAN C made a really nice alternate to GPS and I tended to use it as
the absolute. I do here LORAN
Hi
One thing to be careful about:

than
Loran. Both ultimately trace back to a national standard over very long time
periods.
Eventually that is the limit rather than the accuracy of the transmission
medium.

I wouldn't trust selected OCXO's to be marked systematically
in that case.

Hi Poul-Henning
I agree that option 01 is stated to just mean a "better" oscillator, and I
was a bit confused by what I found, but my second and third units, neither
marked as option 01, have exactly the same oscillator fitted, according to
the SRS label on the oscillator, as my first unit
Hi Iain
I was also expecting a separate chain and GRI, but yes, 63710 seems to be
all there is.
Had me scratching my head for a while but for timing purposes at least it's
just "business as usual":-)
Those extra stations provide the localised corrections that are then
