I know NOAA-15 telem beacon has been received just never decoded. (I found one of the documents about the Telem Beacon to get the baud rate.) https://db.satnogs.org/satellite/25338#transmitters the one with the 8320 baud rate had signals received. It might be that the baud rate still isn’t right or maybe its a weird PSK format. (Like the Phase shift is not what is generally used.)
A few examples I got one the network last year when I still had an active station.
