I belive option 01 doesn't mean "has an OCXO" but rather "has a better OCXO"

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

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
I think Denmark will also cease operation of their one station in line with
Norway and France.
What is the plan for Germany and the UK - not enough stations for a full chain?
New controlling station - since Lessay leaves?

Some time ago I mentioned I'd bought a couple of Minicircuits 16-way power
splitters with the intention of making a 10 MHz distribution amplifier by
amplifying 10 MHz from a GPS receiver and then splitting it 16 ways. Some
had some concerns about that method, but I'd already bought the splitters.

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

One thing to be careful about:

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 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 “use” - Hang on to them and see if the new incarnation of Loran takes hold
in the US.
Second use - Sell them off to the guys in Europe and China while they still
have signals on the air ….
Third - Drive them off some form of synthetic waveform out of a GPSDO.

And if so, is there any backwards compatibility for the old Loran-C units?
