4-7-5. Code squelch
In this squelch system, a digital code is preset by the
local station and the distant station (or among a
group); when the digital code of the transmitting sta-
tion matches the receiving stations digital code
squelch will open and normal communications can
be carried out. This system allows the receiving sta-
tion to wait (or standby} for more than one access
code at the same time.
Code squelch has the following features:
(a) Errors are minimized due to microprocessor con-
trol,
{b} Multiple digital code monitoring.
{c) Each digital code consists of a 5-digit number,
providing approximately 100,000 possibilities.
{d) Simultaneous channel linkage and code squelch
operation is possible.
When the C.SQ key is pressed, incoming signals will
be muted until the proper access code is received.
Code squelch is cleared when any of the following
conditions are met allowing normal voice com-
munications:
(a) The digital access code of the control signal
received from the distant station matches the
local station's standby code.
(b) The C.SQ key is pressed.
(c) The DCL key is pressed and the DCL light goes
OFF.
(d) The PTT switch is pressed.
