From The RadioReference Wiki
The Pro-18 iScan Digital Trunking radio was manufactured for Radio Shack by GRE America Inc.
The Radio Shack PRO-18 iScan is a Multi-Trunking scanner which boasts the ability to track Motorola type I/II systems, LTR, EDACS and P25 systems using the Radioreference database on an included 2GB Micro Secure Digital card.
The Pro-18 uses a proprietary software package-ISCAN and a supplied USB/power cable. Firmware updates are possible on this radio via the PC/IF->USB port.

- Any microSD Card up to 32GB is supported, as long as it uses 512-byte blocks (I've never seen one that doesn't, though the SD spec allows it) and is formatted correctly:
- 2GB or smaller: FAT16, 32kB clusters
- larger than 2GB: FAT32, 32kB clusters
Features found on the GRE PSR-800 Not found on the Pro-18
- APCO P25 Phase II TDMA and X2-TDMA
- Recording / playback
- 200 scan lists (PRO-18 has 100 play lists)
- Tri-color alert LED
- Discriminator output
- V-Scanner II
- Scan Sets
- Clock display while "off" (and connected to external power)
- Auto power-on ("alarm clock")
- "Extra" audio alert tones (PRO-18 has the 7 from PSR-500; PSR-800 has 8 more)
- Power-on password
- 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
- 100 Scan Lists
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 microSD Card space and max FAT32 file size
- Trunked systems: limited only by microSD Card space
- Sites per system: limited only by microSD Card space
- Frequencies per site: fixed at 32 (yes, I know it's too many)
- Talkgroups per system: limited only by microSD Card space, up to maximum for system type
