[time-nuts] LORAN-C Reception on Cape Cod

[Ulrich Bangert]

Hail to the US institutions which first stopped LORAN action long enough so that pricy but apparently useless equipment could enter the shacks of European time nuts for peanuts. Hail to the US institutions for reawakening LORAN so that is is there for you US based time nuts again. The Tracor may be the better solution but  for a quick check the built in phase comparator of the FS700 is more than adequate. My comparisons between  my GPS based GPSDO and the FS700 (using the German Sylt chain) show frequency differences <10E-12 over observation times of some hours or so with the built in comparator.

73s and my congrats to LORAN
