There's only 2 GRE scanners I know of that are P25 capable - the PSR-500 and PSR-600. Search the many threads here on the subject of how good they are....and our wiki has articles on both these scanners. 73 Mike

I like it, very clear on p25 and also analog, PC/IF plugs too your computor and then use the software win 500 or PsrEdit500 to put in your frequencies or down load from the data base or get all the frequencies from someone. I hooked it up to a TV tower and pre-amp not recommended and have some overload but am picking up a lot.

The Gre600C the canadian model

Multi-System Trunking - Scans most common trunked radio
system signaling formats, including Motorola, EDACS, LTR and
P25 trunked radio networks. Both talkgroup and individual call
monitoring are supported.
GRE's Exclusive Automatic Adaptive Digital Tracking - When
monitoring P25 digital systems, instantly adapts the digital
decoder to the digital modulation format of the transmitted signal,
then analyzes the signal over 50 times each second and adapts
to any subtle changes caused by multipath or fading. No
cumbersome manual adjustments are required.
P25 NAC Functionality - Much like CTCSS and DCS with
analog signals, P25 Network Access Code (NAC) is used to
provide selective squelch operation on conventional digital
channels. Your PSR-600C will detect the NAC that is being used
on a P25 conventional digital channel, and allow you to program
NAC codes to block transmissions that do not have a matching
NAC, including analog traffic on the same frequency.

This is from the GRE600 owners manual
