11635 2130 UTC  HM01 transmitting two different recordings at the same time.  One was a few seconds ahead of the other but copy was bad with all the cross talk.  I could pull more copy by going to USB but still roug.  It seemed one of the tapes had different number groups than the other.

Don't watch this like I used to, but increasingly I am convinced they seldom, if ever, send any real traffic.

16:32 UTC 15 FEB 2021 - 11435.0 kHz AM/RDFT

Can faintly heard the Cuban Spy Numbers Station with voice msg groups and data transmissions under what appears to be a strong AM carrier being used in an attempt to jam the transmission.

Due to the strong presence of the AM carrier RDFT could not be received.

16:49 UTC -  End of transmission.
16:51 UTC - The AM carrier was turned off. The strong AM carrier may have been from the Cuban Spy Numbers Station and the transmission may have lacked adequate modulation level.
