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.
