Definitions and Acronyms
Term
Definition
CSQ
carrier squelch
CTCSS
a means of grouping users of a common radio channel—Subaudible tones are
transmitted with audio; a particular radio's speaker (or the speakers of a group of radios)
will unmute to broadcast a transmission only if the associated subaudible tone identifies
it as belonging to the radio's user group.
CDCSS
a system analogous to CTCSS but using low speed digital signaling instead of
subaudible tones
HLGT
high level guard tone
LLGT
low level guard tone
PTT
push-to-talk
