Go to froogle.google.com. Search on Loran. You can still buy
new Furuno Loran-C receivers (but not from West Marine). And
there are plenty of perfectly good units available on Ebay.

In deed you can. You can also find them at ham swap meets next to the old
boat anchor radios and at marine swap meets next to the 8 track stereos.

The point was not that they are unobtainable...but that the product has been
entirely abandoned by the leading retailers.

You can also find differential receivers...which will continue to be
marketed for the big boaters. But you will not find them for long on the
retailer shelves.

The thought that LORAN has some role as a backup to GPS in a military
jamming situation is pretty close to ludicrous. You really think the
electronic warfare guys are not going toimpact long wave? You think LORAN
is resistive of jamming?

Silliness...all silliness.

Not entirely.

But close. Which is what you'd expect for a system who's future was
seriously in doubt until recent interest in keeping it alive. The
current momentum to extend the life of LORAN only started in 2001.

I guess you don't know very much about RF jamming then. If so, you'd
know it's MUCH easier to effectively jam a wide area if you only have to
jam one frequency with extremely weak signals on it than a wide spectrum
of RF with much stronger signals. So yes, LORAN is much more resistive
of jamming than GPS. Orders of magnitude more resistive of jamming.

Yes, that's what I think. GPS is useful in a military situation because
provides extremely high accuracy. Thus selective availability -- the
ability to remove that pinpoint accuracy on demand. Loran does not
provide the accuracy of GPS, therefore is cannot serve the same
military role. Thus there is no militarily-related reason to jam
Loran.

You think LORAN
is resistive of jamming?

No. What I think is there is no reason why the military would want
to.
