[time-nuts] Re: Eloran long test from now to August or September.

There have been various things posted in the past that have required A/Ds
and such. Poul here on Time-nuts did a semi software version. (I think) But
the fact is the old LORAN C receivers for frequency are a great way to go.
The only difference between LORAN C and eLORAN is the 9th pulse used as a
data channel. There was no 9th pulse in the old LORAN C. I have not seen
anything that describes the coding. It may be out there but I haven't been
interested in that. For many of us its an alternate very accurate Cesium
referenced source.
How it all develops if the governments supports it will be pretty
interesting. Certainly the old positioning is possible. The data channel
can provide propagation behaviors to allow for very accurate time and
positioning. The new generation receivers will all be SDR based.
I have actually seen an operational prototype numbers of years ago.
