[time-nuts] eLoran

[paul swed]

Well good news on the old LORAN C receivers all are fine. Turned out I had
a single channel driver bad in the distribution amplifier. Simply used
another output. Preamp is good also.
Ready for next week and warming up the Cesiums for a check with a real
reference. Not that messy GPS stuff. Humor intended.
