PSR-700

From The RadioReference Wiki

Psr700.jpg

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.

Memory Capacity

  • 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.
  1. Select the system
  2. Select the site
  3. Bring up the trunking tables for the system
  4. Set it from Auto-fill to Custom
  5. Hit the Set Reband button
  6. Load the new configuration to the scanner

Thanks to Troymail for the procedure
