PSR-500

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.

• Object oriented memory management. I.e. a talkgroup list "object" can be attached to several trunked systems such as a networked or statewide system
• Built in discriminator data output in simple ASCII output using the PC/IF port
• 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.
• 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.

• Preprogrammed for most major metropolitan areas
• 25-54, 108-136, 136-174, 216-406, 406-512, 764-960, 1240-1300MHz range
• 5 ID lists, 30 IDs per list, 150 IDs per bank
• 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)
• Digital signal processing (DSP)
• CTCSS/DCS abilities
• 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

• 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 SAME Weather Alert and weather priority—access weather channels and alerts with the push of a button
• Skywarn
• Spectrum Sweeper
• "Multiple" Priority channels
• Zeromatic search tuning
• Per channel or global 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).
