[Lowfer] E-Loran

[Stan W1LE]

Hello The Net:

LORAN is receivable here on Cape Cod using GRI 89700 microseconds. The 
same GRI as used with the old Seneca (NY) chain.
New location for GRI 8970 is Indlewood NJ. The site for the Coast Guard 
old LORAN engineering and R&D center.

My Stanford Research Systems FS700 receiver is operational and I can get 
the time of day and 10 MHz output to 1E-10.
Later I will compare it to the Trimble T'Bolt GPS/DO.
The FS700 does lock to the station but does drop out occasionally with 
excessive phase error. (about 5:51 PM est)

Monitoring the LORAN signal at 100 KHz with ARGO shows lotsa LORAN 
lines, but they are not present at 137 KHz.

A few years ago I had a lot of fun monitoring the Nantucket LORAN 
station and could achieve near Cs atomic freq standard accuracies at 10 MHz
using both Austron and the SRS receivers.
