CTCSS - "Continuous Tone Coded Squelch System" CTCSS is a series of
sub-audible tones which are standard on most new radios. An audible
cousin
of CTCSS is DTMF. These tones often perform control functions. Some
repeaters may require a sub-audible tone before activating, others use it
to perform functions such as turning all trunks on and off when a
specific
tone is present. (Also see: Tone Squelch, ETS & PL)
Hrm... this is at variance with your definition of CTCSS.
From
http://www.pacres.com/ctcss.htm :
[quote begins]
CTCSS (Continuous Tone Controlled Squelch System) a sub audible tone in
the range of 67 to 254 Hz. The FM deviation level of CTCSS tones should
be in the range of 500 to 800 Hz. These tones are encoded with the voice
audio at all times during the transmission. Any one or more of the 50
tones can be used to gain access to the repeater. CTCSS decode and
encode is provided as a standard feature on all of our controllers,
using state of the art devices. All standard and non standard EIA CTCSS
tones can be decoded or encoded. You may select 1, 2, 3 or up to all 50
CTCSS decode tones to operate the repeater. You can even use CTCSS tones
and DCS codes on the same channel.

Here, CTCSS is defined as "a subaudible tone" "encoded with the voice
audio at all times during the transmission."
Sure sounds like your SATS definition, and PL to me...
