GRE PSR-800 based scanners

Radioreference uses this term "Object Oriented PC" scanners to describe all the scanners that's direct heritage is from GRECOM America's design of the handheld PSR-800 and unreleased PSR-900.

Sometimes they use this difficult caveat filled listing to "easily" show the models

GRE	Radio Shack	Whistler
PSR-7007	Pro-1077
	Pro-181,5,8
PSR-8002,5,8	Pro-6682,5,8	WS10802,3,8
		WS10882,3,6
		TRX-12,3,4
PSR-9009		WS10952,3
		WS10982,3,6
		TRX-22,3,4

1. Released around the time the PSR-800 was, but lacking additional/advanced features SEE #5.
2. Project 25(P25) Phase I and II decoding.
3. Capable of DMR decoding, with a free Upgrade to the latest Firmware via Whistler's EZ-Scan software.
4. Capable of NXDN decoding, with a free Upgrade to the latest Firmware via Whistler's EZ-Scan software
5. Ability to be Upgraded for DMR (and add P25 Phase II to Pro-18) decode with a Paid Upgrade with User paid shipment to Whistler, returned by them. Once, returned, continued forward support is possible via Whistler Repair and EZ-Scan Software, with all the newer additions and features of a WS1080.
6. Variant with Keypad
7. Trunking w Analog Voice Only
8. ALL THE SAME after UPGRADE except silk screening
9. Never released publicly, subsequently became WS1095

Below are all direct copies Badged-Engineered models with Silk Screening, different Boot Loader versions, and a couple bits in modeling numerics in the scanners base operating firmware, only the faceplate Keypad is different on the intital offering of the Radio Shack Pro-18:

GRECOM produced

GRE: PSR-800 engineered and developed the first SD card based scanners to come to market, as well as a the scanner market's first use of the RadioReference database, as well as the first Scanner capable to listen to APCO 25's P25 Phase II and Motorola's proprietary X2-TDMA transmissions in places like Prince George's county Maryland before the finalization of APCO Phase II.

the Badge Engineered variant for Radio Shack:

• Pro-18 The same except faceplate button design & layout, bootloader and bios numerics

GRECOM America began design and engineering, at nearly the same time, with the PSR-800 coming out first and the PSR-900 base/mobile scanners in a nice DIN package size being tested in private. Through a mountain of push back, from the overseas parent company, to reduce operating cost, the American team was steadily shrunk, until the complete shuttering of US facilities. At which time a buyer was sought for the GRECOM America, Whistler purchased all design and intellectual property of the shuttered American arm. Right before the sale happened the GRECOM AMERICAN team threw every engineer and beta-tester towards getting a working Phase II algorithm written and tested, staying up night and day, and in the final weeks, basically snuck out a beta release with Phase II, to great applause of the scanner community and PSR-800 sales blossomed, but unfortunately it was too little, too late.

Whister resumed production

When Whistler restarted the manufacturing line with the the Badge Engineered version's of the PSR-800 handheld the nearly identical products came to fruition, except for a couple of components that were deprecated and unavailable to be sourced when Whistler's resumed production. Whistler:

• WS1080 & WS1095

Whistler then produced

for Radio Shack:

• Pro-668The same except silkscreening, bootloader and bios numerics

Whistler then produced models with total alpha-numeric keypad faceplate designs

once again off the PSR-800 based scanners WS1088, WS1098

Whistler complete overhaul of GRE PSR-800 based scanners

• Whistler: TRX-1, TRX-2,

Overhualed version of previous generation, with better front-end filtering to reduce overload issues and Whistler's newest faceplate and keypad layouts, with a bigger on-chip memory to increase system type capabilities to include NXDN
