Heard this on my SDR with upconverter on the long-wire that's way too long. Can tell it's OTR and did hear one ident stating I was listening to James Stewart in...something.
Have been actually listening since around 1005 after finding it accidentally. Doing some major fading in and out, making it difficult to really keep up with what's going on. Heard a MFSK signal on the upper end of the USB a few minutes ago.
Audio Sample because I can.
*Update: 2245: Still going; fading in and out over 20 second cycles. Updated screenshot with timestamps and closer waterfall.*
