I'm am looking at 60kHz at the moment, MSF appears to be off air, but I am receiving a weak signal from what is clearly a time code signal as it pulses at one second, but its phase is a bit unstable.
Andy, probably not Boulder as you should see the BPSK with 180 deg. phase reversals which, when present, are located in the -17dB dips. http://www.nist.gov/pml/div688/grp40/upload/NIST-Enhanced-WWVB-
Hello Andy, The odds at this time of the year are that it is JJY from Japan. time code are different. In lieu of the year bits, the station's call sign is broadcast at 100% modulation during seconds
Hello Andy and Roelof, Ditto here, see attachment or listen to my audio file from 2012 at https://www.dropbox.com/s/qcwvsteike2dyu1/JJY_60kHz.mp3?dl=0 JJY can be identified by its CW ID every h+15min
