As I understand it, 60 KHz information is so slow that phase information is critical. Why would anybody use a resonant antenna in that situation? The phase shift from day to night is more than enough to work around.
I used a non-resonant antenna proposed by John Ackermann against Z3801 outputs and got decent results, but not like comparing the Z3801 outputs against a Cs standard. John's antenna should be in the archives. Just 100 feet of RG-58 wound on a 4 foot diagonal PVC pipe frame, with the shield split at 50 feet, IIRC. Tried resonating it, got unstable results. If you really must work with WWVB, I have a Spectracom 60KHz receiver and extras in a Tektronix rack or a Fluke 207 for sale at moving sale prices. I never thought there'd be any interest.

I've been gathering information on Black Hole Antennas for a while on my web site: http://www.unusualresearch.com/Sutton/sutton.htm Anyone come across anything new? Always did want to try one for 60 kHz. -- http://blog.softwaresafety.net/ http://www.designer-iii.com/ http://www.wearablesmartsensors.com/ _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
