0x - The nomenclature "0x"
is used to indicate hexadecimal numerical values. Hexadecimal
is a base 16 numbering system. Hexadecimal values are easy to
translate into 4 bit binary values. Here is an example:

Calculator programs like the MS Calculator in Scientific view
can convert between Hexadecimal, Octal, Decimal and Binary number
bases.
Alternate Control Module - This is a style of mode select
control head with push button mode selectors.
Binary - Binary is a base 2 numbering system. Digits
0 and 1 are used to represent binary values. Binary is most often
used by computers, in this case as the Syntor X micro-computer
or Syntor X 9000 micro-computers.
CEPT - Conference for
European
Postal
Telecommunications administrations. This
has to do with specific European compliance issues.
CH - This is an abbreviation for
Control
Head.
Clamshell Control Head - This is a style of mode select
control head with a rotary mode selector.
Code Plug - Your program with
all the frequencies and information that you save inside the radio
(i.e. Rx and Tx frequencies, Rx and Tx PL/DPL, scan modes, Tx
timeout timer, etc.).
Common Circuits Board - The Syntor X printed circuit
board which contains the radio's audio portion of the transmitter
modulation circuits, transmitter protection, receiver squelch
and voltage regulators. The Syntor X 9000 circuit board is similar
except it does not have any transmit audio circuits and it added
an unswitched 5 volt regulator.
Conventional - Conventional radios
are the traditional radios. They allow simplex or duplex (i.e.
repeater) communications. Conventional radios are less complex
than trunking radios. However, conventional radios allow greater
interoperability with other conventional radio systems (i.e. there
are no problems with incompatible trunking formats to prevent
communications). Also see
Trunking.
COR -
Carrier
Operated
Relay. It may also be called
COS for
Carrier
Operated
Switch. This is a control used by repeaters.
When the repeater receiver detects any signal, it asserts the
COR as an output to send to a repeater controller. The repeater
controller can use this signal to decide when to turn the repeater
transmitter on.
