P25 Problems
|
Time owned: 3 to 6 months
|
OK so the PSR-600 works great on non P25 trunking systems with the usual intermod these consumer grade widebanded recievers suffer from. Wait a minute, the new Motorola systems are P25 CQPSK LSM simulcast systems. Right, and the PSR-600 is very poor in performance on these types of systems. Everyone should be aware that these new APCO 25 systems with CQPSK/9600 baud control channel and simulcasted is what is coming to a city, county or state near you. Having spent time speaking at length with the brain trust at GRE as to why their PSR-500/600 is so bad on these systems, the only thing they could tell me was its very difficult to decode CQPSK LSM and they have tried everything with the firmware to correct this issue but still it remains. If your in doubt do a web search on the issues the GRE PSR-500/600 had with cities with the P25 systems like Petersburg, VA and Arlington, VA.
My advice to any considering this scanner and your city, county is going to a Motorola P25 7.X CQPSK LSM simulcast system you will be very unhappy with the performance of this scanner. Oh as a side note the Uniden scanners suffer from the same issue. How do I know this?? I own several P25 scanners, Pro-2096, Pro-96, Uniden 396, GRE PSR-600. They all are poor in the true P25 type systems. It would take very careful alignment and much better internals to really make these perform like they do on non P25 systems. Lucky for GRE, Uniden there are not that many P25 systems today, but its the only thing Motorola sells in the trunking world. Sooner or later your cities old Analog or Type II or 3.X/4.X system will be replaced with you quessed it a P25. If GRE or Uniden was to build a scanner that properly decodes CQPSK LSM simulcast systems it would cost at least twice maybe 3 times what your paying now.

Packed with Features
|
Time owned: 3 to 6 months

Right Now (2008) this is the best digital trunking scanner on the market. The most bells and whistles of ANY scanner. You must have software and a computer to fully realize the potential of this radio. Audio is better than any Uniden I have owned. GRE listens to owners and is constantly adding new features thru a internet firmware download. This scanner is a must have if you need digital trunking in a scanner.

UNIDEN is loosing the Game with this one!

The Best Damned Scanner on the Market, all the lastest technology.
Horrible "tiny" little screen, but the SPEED, sensitivity, Digital Audio, and NAC Digital Tone decoding features beat all of the UNIDENS!

Great Scanner -
|
Time owned: 0 to 3 months
|
After several months I have to say this is overall the best base scanner to date.
Pro: Sensitivity is great, and for distant signals this unit kicks butt. I appreciate the ability to handle NAC codes, something I haven't seen on other radios. The LED and various alarms are useful for warning you when that channel you've been looking for activity on comes alive. Audio boost is a great feature for quieter channels. Digital sound quality is the best of any scanner yet, no "under water" sound. The most features / options of any scanner yet. More likely to "latch onto" a transmission than other scanners I have tried. Awesome support from GRE with regular updates to cpu and dsp.
Con: Finding an "object" can be a bit odd, and the display is not nearly as nice as the BCD996T. Search steps not selectable as far as I can tell, though you can enter a frequency in as an object with whatever spacing you like. More sensitive to overload than the Uniden competitors.

Good performer -- bad overload.

I have had the PSR600 and also a Uniden BCD996T for several months now. (See my review of the Uniden in the appropriate section of e-ham reviews). The PSR600 has better sensitivity on 138-174 MHz. The Uniden is more sensitive on 380-400 MHz. and the two are comparable on the other bands. I find P-25 modulation decoding a little better on the PSR, but software upgrades may equalize the two. The Uniden display is nicer. My primary difficulty with the PSR600 is overload from f.m. broadcast and TV transmitters on high-band. Even with the attenuator engaged overload is a factor. Without the attenuator engaged I experience full deflection of the S-meter even on frequencies with no in-band signal present. Even strong local signals have trouble overriding the overload from broadcast transmitters many miles away. If you use an outside antenna, you will certainly benefit from an outboard filter for f.m. and TV channels 2-6. It is indeed lamentable that neither GRE nor Uniden have kept the quality of their earlier radios! The newer radios have all the bells and whistles but are lacking in the r.f. department, especially between 138-174 MHz.

The best made to date

I have owned my psr 600 for over a month now and it's a very impressive unit.I have owned all of the latest digital scanners including the 996t from uniden.Let me first say nothing on the market today can compare with this scanner..Okay now as for performance 25-50 mhz this scanner is very sensitive although it's not used much anymore the scanner perform's very well.On vhf from 108-174 mhz probably the most sensitive scanner i have ever seen and i have seen my share,This does have it's drawback's as it does overload easy but the attenuator works great and solves this without a hitch even with it activated it still out perform's all others that i have seen.And on uhf air it does very well..406-512 exellent same as vhf just can't be beat the digital decode is the best never heard the machine gunning that all others suffer from, it decodes fast and great audio .There is nothing out there that will beat this unit at 800mhz if you can't hear it it's not there plain and simple.GRE customer support is by far the best..This thing trunk's like a bloodhound with the newest firmware installed it really gets with the program.If your looking to buy a digital scanner the buck stop's here..I have compared all the new digital's side by side and this one blow's the other's out of the water..
