GRE COM PSR-500 scanning receiver

The PSR-500 is manufactured by GRE in China. The PSR-500 is very similar to the Mobile/Base version of the PSR-600 and uses the same radio control software and Scanner cables.

1240-1300              6.25 kHz

  • Object oriented memory management. I.e. a talkgroup list "object" can be attached to several trunked systems such as a networked or statewide system. There are "Scan Lists" where you group the objects you wish for scanning. You do not need to enter frequency or talkgroup info more than once as you can just use those "Objects" in the scan lists as you desire.
    • You navigate Objects in MAN mode: Just use the Arrow Keys. Up/Down scrolls within a scan list, and Left/Right scrolls to change scan lists. You can also just type the Object number and press SEL. Also in PGM mode, there is a FIND option and you type Alpha/Numeric (partial or full) and it will search the number and text fields in every object and let you choose to monitor (MAN), or press NEXT (Softkey) to keep FIND-ing.
    • Hold: You can pause while scanning, or now the MAN mode is fully trunking so you can just "FIND" on some Conventional, Search, or Talkgroup, Sweeper, alpha or number data, and then press MAN.
  • Built in discriminator data output in simple ASCII output using the PC/IF port
  • Full duplex support and USB connetion using the GRE 30-3290 (RS #20-047) USB Scanner Data Manager Cable.
  • Object programmable LED; eight factory default colors to any color / brilliance you want by having direct access to the R-G-B drive values to assign to talkgroups, frequencies, agencies, etc.
  • Spectrum Sweeper Near field frequency capture
  • 11 tuning steps including 5, 6.25, 7.5, 12.5kHz
  • Triple conversion
  • 20 dB atenuator
  • Rebanding supported? YES
  • APCO25 Digital Audio decoding
  • Trunktracks Motorola, EDACS(wide/narrow/SCAT), and regular LTR systems
  • Virtual Scanner Memory Management system stores 21 memory configurations, each with 36,000 channels and 16,000 talkgroups and Dynamic Scan Lists.
    • The V-Scanners work like the Radio Shack PRO-96 in that they store the radio's working memory (settings, frequencies etc.) to a seperate area of internal memory. The radio's main memory is no longer banks/channels, but "objects". The Scan lists are now how you group the objects for scanning and you toggle them on/off with the traditional method of pressing the number keys during scanning. The arrow keys do not page through the V-Scanners. The V-Scanner function is in a separate menu much like the Radio Shack PRO-96.
    • When creating a talk-group object, you associate the talkgroup-object with the system object. The system-object has all the control channel informationand is only entered once. Scan lists can have pointers to talkgroup-objects such as Fire, EMS, Police. As you create the talkgroup-objects you can assign them to any number of scanlists while you create them. You can also edit the scanlists later. You only create a system-object once, and associate multiple talkgroup-objects with it. Then the talkgroup-objects can be pointed to any number of scanlists (including none if you want to temporarily just set aside the talkgoup, but not delete it). If a talkgroup-object points to a system-object the paused talkgroup will stay synched up with the entire system over multiple control channels.
  • Preprogrammed for most major metropolitan areas
  • 25-54, 108-136, 136-174, 216-406, 406-512, 764-960, 1240-1300MHz range
  • Scan rate 60 cps
  • Search speed 90 CPS
  • User defigned service search and limit search
  • Direct Tune mode
  • TCXO for frequency stability (?)
  • Digital AGC
  • Adaptive digital tracking (ADT)

  • Network Access Code can be programmed to only break squelch when receiving the correct NAC in a conventional P25 system.
  • 16-character alpha-tagging with text entry can show ID code or service name
  • L/O ID in 'open' mode
  • ID delay
  • Motorola control channel only trunking
  • I-Calls, possibly displayed as hex as mentioned at Dayton Hamvention 07'
  • 700MHz Trunk Scanning
  • Easy-to-read backlit control and display with backlit keypad
  • 6 search ranges/ 1 user definable search range
  • Search 'seek' feature
  • Tunes virtually all important bands—local marine, fire/police, Ham, CB, VHF-air, UHF-Air, racing, weather and more
  • Weather band with enhanced SAME Weather Alert functions and weather priority—access weather channels and alerts with the push of a button
  • Skywarn
  • Spectrum Sweeper
  • "Multiple" Priority channels
  • Zeromatic search tuning
  • Attenuator
  • Computer interface and Programming (with computer control)
  • 3 user programmable function keys and 5 way navagation keys to access special modes and programming options
  • 4 line x 16 charactor display with relitive signal strength meter
  • 9V DC 4xAA batteries with regular(black) and charging(yellow) cases
  • BNC connector
  • A cloning cable may be fabricated using 2 1/8 inch mono jacks and shielded cable
  • Verifying the firmware version

You can verify the version of DSP firmware currently active in the PSR-500 by pressing the 3 key during the “Welcome” screen.

Future firmware upgrades can be installed by downloading and running an upgrade program (TBD).
