Glossary
Conventional
Typically refers to radio-to-radio
communications, sometimes through a
repeater (see Trunking).
Conventional Scan
List
A scan list that includes only conventional
channels.
Digital Private Line
(DPL)
A type of coded squelch using data bursts.
Similar to PL except a digital code is used
instead of a tone.
Digital Signal
An RF signal that has a pulsed, or discrete,
nature, rather than a continuous nature.
Dispatcher
An individual who has radio system
management duties.
Dynamic Regrouping
A feature that allows the dispatcher to
temporarily reassign selected radios to a
single special channel so they can
communicate with each other.
Failsoft
A feature that allows communications to
take place even though the central controller
has failed. Each trunked repeater in the
system will transmit a data word informing
every radio that the system has gone into
failsoft.
FCC
Federal Communications Commission.
Hang Up
Disconnect.
KVL
Key-variable loader: A device for loading
encryption keys into the radio.
LED
Light-emitting diode.
Monitor
Check channel activity by pressing the
Monitor button. If the channel is clear, you
will hear static. If the channel is in use, you
will hear conversation. It also serves as a
way to check the volume level of the radio,
since the radio will “open the squelch” when
pressing the monitor button.
