Radio Terminology

What are some basic 2-Way Radio Terminology?

  • Accelerated Life Test – a Motorola proprietary developmental process of rigorous laboratory testing that simulates years of field use.
  • Built-in Noise Reduction Microphone – reduces background noise to allow clear, understandable transmissions in heavy noise environments.
  • Call Alert – lets a caller “page” you via your radio.
  • Channel Scan – lets you monitor specific operating channels.
  • Priority Scan – allows you to choose one channel to be monitored with more frequency than the others.
  • Operator Selectable Scan – lets you program the channels in the scan list to be monitored and select a priority channel.
  • Scan Nuisance Delete – allows you to temporarily delete a non-priority channel from the scan list.
  • Talkgroup Scan – lets you monitor any combination of trunked systems, subfleets, or conventional channels in the same scan list.
  • Dual Mode Capability – provides the flexibility of trunked and conventional repeater operation from one radio.
  • Private Conversation – allows communication exclusively between the initiating radio or control station and the radio called.
  • Privacy Plus Trunking – provides fast, automatic and democratic communications access not provided by conventional radio systems.
  • Radio-to-Radio Cloning – allows you to duplicate one radio’s operating parameters into another like radio of the same sub-band using a simple cloning cable.
  • Internal Voice Operated Transmission (VOX) – lets you activate radio by voice alone, for hands free operation.
  • Multiple Coded Squelch Capability Private-Line (PL) or Digital Private-Line (DPL) – lets you receive only the calls intended for you, and place calls to only those that accept the designated code.
  • Push-to-Talk Interface – allows a dispatcher to identify transmitting radios and monitor airtime usage.
  • Quik-Call II Signaling – provides an efficient way for dispatcher to initiate a page to an individual or group.
  • Field Programmable using the Radio Service Software – changes can be made to the radio frequencies or other individual characteristics.
  • Talkaround – lets you bypass a repeater and talk directly to another unit.
  • Telephone Interconnect – gives you the capability to initiate and/or receive telephone calls using your radio.
  • Time-out Timer – limits the amount of time a user can continuously transmit on a channel.
  • Voice Selective Call Signaling – provides an efficient way to initiate a voice page message to an individual or group.
  • Emergency Alarm – used by radio operators to inform dispatch personnel of critical or life threatening situations through a data transmission.
  • Programmable Channel Spacing┬á (Wide Band Frequency Separation) – gives you more versatility of channel spacing.
  • Alphanumeric Display – lets you name and view channels or talkgroups in words instead of numbers.
  • Busy Channel Lock-Out – prevents users from “talking over” each other by restricting transmission if activity is detected on the channel.
  • Horn and Lights Capability – activates a vehicle’s horn and headlights when a Call Alert signal is received and the operator is away from the vehicle.
  • Military Specifications Mill Std. 810 C, D, and E – the U.S. Department of Defense’s most rigorous standards for radio performance in harsh environments.
