cdcss code guard values
Codes for the CDCSS Code Guard system may be chosen from the
following list. Since there are no EIA standards for the performance or
compatibility of CDCSS Code Guard systems it is recommended that
an operational test be made on the intended system before wholesale
assignments are made. In some cases either or both transmit and
receive codes will require an inverted code to operate with existing
systems. This can be done during the code programming of the system.
Usually systems using direct Unit-to-Unit transmission (systems without
mobile relays, repeaters, remote control, etc.) may use codes from the
table. Systems with relays, etc., may use code variations for systems
control and operational efficiency. The system operator or engineer
should be consulted regarding the operational requirement on such
systems.
