Two new developments.
One, HM01 has a new number group as of yesterday (1/24) and another today (1/25). Although there is a file being transmitted for each, it's either resending the same file that is associated with the immediately preceding group, or it's sending some kind of null file that the DIGTRX program can't produce. The Rx window is simply blank and no new file appears. If there were error messages then I would know that the file has bad blocks or something, but since it's giving no errors I can't say that they're sending a bad file, or that I'm having poor reception (I'm not, and the DIGTRX program is running smoothly). I've documented this over on my January 2017 HM01 log.
Two, I was just listening to HM01 on 11435, it's regular frequency for the 1600 UTC hour, when it suddenly cut off in the middle of a RDFT transmission at 1649z. I looked at the waterfall and the carrier was gone, however you could see one at 11530, it's regular frequency for 1700. I went over there and the broadcast was happening. But it ended normally, leaving the carrier. So far, this is a typical mistake that they make.
However, something new then happened. At 1652 voices were briefly heard, faint but clear enough to copy - get this - Brother Stair. It went away, but was heard again briefly at 1654. It was unmistakably Brother Stair. I don't have a recording unfortunately. Normal HM01 transmission began at 1655.
EDIT: WRMI has a transmitter on 11530. They only use it two hours a day, and not for TOM, but it's still possible that the Brother Stair snippets came from them.
