US west coast eLoran test in progress (GRI 5990)
I happened to stumble across very strong 100 kHz Loran-C on the KPH (California west coast) Kiwi last night. A GRI of 5990 is normally the Russia Caucasus chain, which is active according to the Germany-based recordings of DF6NM. But there was no way KPH was hearing that.
