[This was broadcast in DSB. As with an earlier session a few days ago, the
LSB component was much weaker than the USB component; and, the LSB audio
was clear. The USB audio was noticeably different. It was as if there were
two different transmitters involved with the broadcast. The DSB session
appeared to be confined to western CONUS reception; USB elsewhere.]
