Re: [IRCA] [NRC-AM] LORAN-C 100 kHz Nantucket

["Steve Ratzlaff" <steveratz@xxxxxxxxxxxx>]

The Canadian and USA east coast and midwest systems were shut down in 
February; the far-west Canadian and Alaskan systems just shut down a week or 
two ago. The Far East Russian remaining chain (GRI 5980) is still in 
operation. I get it fading in every morning for 30-60 minutes, otherwise 
100kc is blissfully silent. The master station at George, WA was my 
strongest radio signal, and I had to use a homebrew Loran notch filter to 
stop the intermod in my radios. I'm thrilled that they are finally silent.
