Andy,
probably not Boulder as you should see the BPSK with 180 deg. phase reversals which, when present, are located in the -17dB dips.

Maybe they are adjusting something at MSF at reduced power and that is what you see? Perhaps JJY-60 from Japan?

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. It shifts plus/ minus perhaps 10 - 20 degrees in a random manner. 

Could this be Boulder ?
