[time-nuts] eLORAN 99600 monitoring at 100 KHz

Dana
Its on the air now.
Its a 4-8 foot whip that screws into the top of the preamp. Its just a
marine boat loran c antenna they were $30-50. Seriously nothing exciting
about them. Do a search on loran c antenna. When loran c was active
they preamp and antenna could be had inexpensively.
I will believe Texas is too far away to hear the transmitter.
I know it reaches out to Indiana pretty well.
Regards
Paul
