[time-nuts] eLORAN 99600 monitoring at 100 KHz

[paul swed]

Dana that was 11:29 am when you emailed me. Looking at the 3586 its -49 db
now.
To your second question I can't really know that. Its a standard marine
preamp. Might guess 20-30 db. But its nothing special. Made by a company
STS. Classic FET, filter , 2 X transistor design. It would be a bit of a
math guess to use the 3586 reading and deduce the actual field strength.
