Not quite right. Apparently the old Loran C
equipment can be repurposed to broadcast the eLoran signals, but the old receivers will still be paperweights. No one seems to make definitive statements but I did find " NIST was offering to fund development of a microchip sized eLoran receiver for distribution of timing signals.[6]" on the Wiki, so it appears that all new
equipment will be needed.
Internet asking prices are really meaningless. I've seen products listed on Amazon at, literally, $380 when another vendor was selling them at $25, the actual MSRP. Some of those offers you see may in fact be criminals or terrorists "communicating" with each other, by placing ads that they know no one will respond to. This is just the new version of the old "ad in the classified seeking the man who
lost a blue shoe in the park".
And then some folks are just sheep to be sheared, i.e. "Oh, that looks like a good present for dad, he doesn't have one of those". Hey, its the only one
for sale, right?
Could still take 15 years for a system to get deployed, especially as they are talking international, and IIRC some of the US stations were dismantled or stripped.
