[time-nuts] Any other useful purpose for Austron 2100F or SRS FS700 receivers in US

Hi,

For the USA and Canada, currently LORAN-C is history.

However, LORAN-C signals is still relatively well know and eLoran is a 
backward compatible change for which there already is a market, so that 
is good.

I think I recall another digital signal being discussed as a side-band, 
which I also think I saw some specs on in an article, and it looked 
interesting. We did discuss it on the list many moons ago, maybe someone 
recalls and can dig up the references.

I have a FS700 for which I currently does not have a proper antenna. I 
coiled up some twisted pair, but it complains about no external LNA, so 
I will have to create something which acts as LNA and essentially forms 
the same DC load to the FS700. I have the SC-10 OCXO in mine, and as I 
recall, I think I saw GRI 80000 from russia. It would be nice to run it 
for a while.

Cheers,
Magnus
