[time-nuts] eLORAN 99600 monitoring at 100 KHz

[Dana Whitlow]

Thanks, Paul.

Does this "standard marine preamp" have an integrated antenna of some kind?
If not (or  you're not using it), can you tell me about the antenna you
*are* using?

I've not "heard" so much as a peep here in south central Texas, but have
only
looked in the daytime.  Is the station transmitting around the clock?

I do suffer from an abysmally-high noise level here.  But I'm trying to get
a
handle on whether it's even worth my trying further.

Dana
