The GRE PSR-300 hand held scanner is one of a new generation of scanners designed to track Motorola Type I and II (such as Smartnet and Privacy Plus) and hybrid analog trunking systems, GE-Ericsson (EDACS) type systems, and EF Johnson (LTR) type systems which are extensively used in many communication systems

  • Triple Trunking Operation – tracks three trunking systems (Motorola, EDACS, and LTR) and conventional systems at the same time
  • 10-Channel Storage Banks – let you store 100 channels in each bank (total 1,000 channels) to group channels so calls are easier to identify
  • SAME/FIPS Weather Alert – displays the weather event for the specific cities or counties you choose so you can hear the alert tone.
  • Data Cloning – lets you transfer the programmed data to another PSR-300/400 scanner. You can also upload or download the programmed data to or from a PC using an optional USB Scanner/PC Interface Cable
  • 16-Character, 4-Line Alphanumeric Display – shows you detailed operating information clearly.
  • Spectrum Sweeper – a powerful new tool for you to rapidly detect, monitor and store frequencies for nearby radio transmissions.
  • Preprogrammed Frequency Ranges – lets you search for transmissions within preset frequency ranges or within ranges you set, to reduce search time and select interesting frequencies more quickly.
  • High-Speed Scan/Search – the scanner scans at up to 60 channels per second and searches up to 78 frequencies per second, to help you quickly find transmissions.
  • Priority Channel – lets you set the scanner to check one channel every 2 seconds so you do not miss transmissions.
  • Attenuate – let you program your scanner to reduce the scanner’s sensitivity to strong local signals, to reduce interference or noise caused by these signals.
  • Text Input – lets you input a text label for each channel, talk group ID, or bank so you can easily identify the transmission
  • Lock Out Function – lets you set your scanner to skip over specified channels or frequencies when scanning or searching, and skip over IDs when tracking trunked systems.
  • Key Lock – lets you lock the scanner’s keys to prevent accidentally changing the scanner’s programming
  • Supplied Flexible Antenna with BNC Connector – provides good reception of strong local signals. You can connect an external antenna with a BNC connector to the scanner for improved reception of distant/weaker signals
  • Memory Backup – keeps the frequencies stored in memory for an extended time even without internal batteries
  • Three Power Options – you can power the scanner from internal (rechargeable or non-rechargeable batteries) or external AC or DC power (using a supplied AC or optional DC adaptor)
  • 1-year Manufacturer's warranty
