Guess you could mix data with voice but I took it to mean the use of a control channel.

20K0F9W

20K0 bandwidth

F Frequency modulation

9 Composite system with one or more channels containing quantized or digital
information, together with one or more channels containing analog information

W Combination of the above (Telegraphy - for aural reception, Telegraphy- for automatic reception, Facsimile, Data transmission, telemetry, telecommand, Telephony ( including sound broadcasting) Television (video))
