I recorded to tape cassette GDR radio shows on VHF that broadcast code, usually for the GDR "KC 85" 8 bit computer line (U880 processor - Z80 clone).
Funny thing is, you could easily tell from the sounds if the code was assembler or BASIC. The latter was much more orderly and structured.
Problems occurred when someone nearby turned on an electrical device during that transmission, because it was audible and introduced too much of an error and the recording became unusable.
