-	DATA Signals are pretty much everything else. If it goes through a modem or is computer generated before being transmitted to the open air it will probably be included in the DATA Signals section. This includes digital voice modes, including many encrypted modes. The DATA Signals section is loosely broken down into the type of modulation used for the data, FSK, MFSK, PSK, etc.	+	DATA Signals are pretty much everything else.

-	Various image modes, such as HFFAX, SSTV, etc, are included in the DATA Signals, even when they are not digital in nature. Despite many of these types having analogue backgrounds most are generated by computer today.	+	Various image modes, such as HFFAX, [[SSTV]], etc, are included in the DATA Signals, even when they are not digital in nature.
