Maybe this info will get the attention of the "What do we need Loran for" crowd.
I still use my Loran C with joy. Other than those fickle changeover zones which you only hit every 600 miles or so for a brief unusable indication, I find my Northstar Loran to be as accurate as the GPS. As a matter of fact, the overlay of an NDB approach using all three finds the ADF to be the worst, the GPS to be second worse, and the LORAN C to be the best. Every time I switch it on I expect to get no signal acquisition, having been hearing about it being switched off for a decade now. I smile and love it when it's still up and running.
