This scanner from GRE America Inc is similar to the PSR-800 without digital capability and only 51 scan lists.
The GRE PSR-700 iScan is a Multi-Trunking scanner which boasts the ability to track Motorola type I/II systems, LTR and EDACS trunking systems using the Radioreference database on an included 2GB Secure Digital card.
The PSR-700 uses a proprietary software package and a supplied USB/power cable. Firmware updates are possible on this radio via the USB port.
- Rebanding supported? YES EZ-Scan will import tables for identified rebanded systems from the RadioReference database.
- Full duplex support and USB connection using the supplied USB Scanner Data Manager Cable, however it will not access the SD card in the radio.
- Operating voltage
- DC 2.4 Volts (“AA” cell x 2pcs. Ni-MH Batteries).
- DC 3 Volts (“AA” cell x 2pcs. ALKALINE Batteries).
- Ext. power and charge voltage USB Power (DC 5V 500mA).
- BNC connector.

- Object oriented memory management. See the Object Oriented Scanning Described article for more information.
- Object capacity (Nominal, with 2 GB SD Card): > 10 million, varies depending on user configuration.
- 51 Scan Lists; 50 regular lists and a SkyWarn list.
- 200 V-Folders with second generation Virtual Scanner Memory Management system. One copy of working memory can hold a virtual numbers of objects, meaning any combination of talkgroups, conventional channels, and trunking systems. Each V-Scanner II folder holds one copy of working memory. Actual memory size is determined by the size of the SD card memory size used.
- SD Preprogrammed with entire USA & Canada Radioreference database with ability to update as needed or once a week.
- 4 way navigation keys to access special modes and programming options emulating today's standard media player operation.
- Easy-to-read back lit control and display with back lit keypad with user selectable settings.
- Simple display option will display object and scan list only, or disabled for more detailed display.
- Spectrum Sweeper Near field frequency capture.
- Programmable Backlight Flash Patterns - The backlight can be programmed to flash with custom flash patterns when certain objects are active, providing another way alerting the operator when important radio traffic is present.
- Audible Alarms - programmable audible alerts can be configured when certain objects are active.
- Autoboost (software only) - available for conventional frequencies, IDs, and entire trunked systems, boosts the audio levels slightly louder.
- Priority Scan - the scanner will sample conventional objects for activity periodically while scanning and monitoring other objects. The scanner will also give IDs priority over other IDs while checking a particular trunking system for activity.
- Scan rate 75 CPS (without trunk scan).
- Search speed 85 CPS.
- Triple conversion.
- Programmable Welcome Screen text.
- CTCSS/DCS abilities.
- 16-character alpha-tagging with text entry can show ID code or service name set per the users preference.
- Signal strength meter.
- Battery meter.
- 700MHz and 380MHz trunk scanning.
- Multi-site trunking.
- Trunking option to look for the site with the best received CC decode rate (not the same as RSSI on the Motorola rigs, but similar in operation}.
- Motorola Control Channel Only trunking.
- Private Calls and RadioID display in decimal or hex.
- Note: If RadioID is greater than 9,999,999 (decimal), then HEX is displayed to fit in the 16 character display.
- EDACS and Motorola TGID Patch (when used on system), currently in the HEX display format only.
- Regular LTR trunking with auto-arrange for LCN.
- FlexStep - allows you to enter a frequency in any 1.250 MHz step.
- 20 dB attenuator global and per object settings.
- 7 service search ranges/ 1 user definable search range tunes virtually all important bands; marine, fire/police, Ham, CB, VHF-air, UHF-Air, and racing.
- Zeromatic search tuning.
- Weather band with enhanced SAME Weather Alert functions and weather priority—access weather channels and alerts with the push of a button.
- Skywarn List can be programmed with any number of "objects".
- 2 second default delay can be set from 0 to 60 sec.
- Skip or Lockout - lets you skip or permanently lockout any programmed object. All skipped objects can be restored (unskipped).
- 250 Search lockouts.
- Internal battery charger with power from the supplied USB cable or an external USB power AC or DC converter.
- Low Battery Alert for NiMH and alkaline batteries.
- Default Options Key; return to default settings for any menu.
- Conventional channels, each in two playlists: 8 million
- Trunked systems, minimum 20 talkgroups per system: 6 thousand
- Trunked systems, every possible talkgroup (~65,000) in every system: 151
- Minimum number of total talkgroups (@ one per system, 6000 systems): 6 thousand
- Maximum number of total talkgroups (@ ~65,000 per system, 151 systems): 9.8 million
- Entire USA RadioReference database imported (including digital): twice
In the above, each trunked system has up to 50 sites (though there's no practical limit). All talkgroup numbers presume all systems are "Motorola Type-II" - the system type that a) uses the most space per talkgroup, b) potentially wastes the most space per talkgroup, and c) has the largest number of possible talkgroups. The minimum and maximum numbers of talkgroups are absolutes; actual values depend on system types as well as how talkgroups are distributed among systems and within systems. No "RadioIDs" are included in the above.
In more general terms:
- Conventional channels: limited only by SD Card space and max FAT32 file size
- Trunked systems: limited only by SD Card space
- Sites per system: limited only by SD Card space
- Frequencies per site: fixed at 32 (yes, I know it's too many)
- Talkgroups per system: limited only by SD Card space, up to maximum for system type

Setting Up a System for Rebanding
- NOTE: This procedure was discovered using EZ-Scan on the PSR-800; it's assumed this procedure will also work here. Corrections are solicited.
- Select the system
- Select the site
- Bring up the trunking tables for the system
- Set it from Auto-fill to Custom
- Hit the Set Reband button
- Load the new configuration to the scanner
Thanks to Troymail for the procedure
