    Will it work with the new WWVB format?

    "In the second of the two formats, based on PM, which has been in use since
    October 29, 2012, binary-phase-shift-keying (BPSK) modulation is used,
    wherein the carrier's phase is unaffected when conveying a "0", and is
    inverted (i.e. 180-degree shifted) when conveying "1". This time code, also
    operating at a rate of 1 bit/sec, is delayed by 0.1s with respect to the
    first time code described above, such that 180-degree transitions in the
    carrier phase can only occur 0.1s after the 17dB power reduction that is
    created by the pulse-width-modulation. The data content, physical properties
    and scheduling features of this BPSK time code may be found here:
