This is great!
I turned on my LORAN-C receiver (23 Oct 2016 0130 UTC) and it found the master station (Dana, in GRI 8970)!

On a lark, I bought a SportNav on eBay for $25 a couple of months ago. All its said since then for the SNR display is that it was searching and can't find anything. Until tonight.
This is truly exciting.
0135Z - It found Seneca and is trying for Baudette, but alas... nothing.
24 Oct 2016 0001 UTC: Dana & Seneca are gone now. Don't know when they went away.
