This is not an error or a problem, this is the new format HM01 transmission that has been noted for a few months now.  The YL voice starts by saying 6 (maybe it is 6, I am at work and do not have my notes with me, could be 7) five digit groups repeatedly.  It then goes into a single 5 digit group and then digital data, single 5 digit group digital data, repeat, repeat, 6 or so times.  The single 5 digit groups said before each bit of data are one of the 6 five digit groups that was repeated at the beginning, stepping through each until they have all been done.

Example  (keep in mind I am working from memory here, so might be minor errors but it will give you the general idea):

YL voice starts:
72125  66035  38025  56177  60354  75101
72125  66035  38025  56177  60354  75101
72125  66035  38025  56177  60354  75101
72125  66035  38025  56177  60354  75101  (I don't remember how many times she repeats)
72125  digital data stream
66035  digital data stream
38025  digital data stream
56177  digital data stream
60354  digital data stream
75101  digital data stream
72125  66035  38025  56177  60354  75101  (I don't remember how many times she repeats, this might be a single)
72125  digital data stream
66035  digital data stream
38025  digital data stream
56177  digital data stream
60354  digital data stream
75101  digital data stream
72125  66035  38025  56177  60354  75101  (I don't remember how many times she repeats, this might be a single)
72125  digital data stream
66035  digital data stream
38025  digital data stream
56177  digital data stream
60354  digital data stream
75101  digital data stream
72125  66035  38025  56177  60354  75101  (I don't remember how many times she repeats, this might be a single)


etc.

RDFT.  DIGTRX will demodulate the data if you can keep it running.
