What are the differences between the 2 and which is a better radio?
I know the 97 doesn't have 700MHZ band.
Thanks,

While the PSR-310 may have the 700MHz band, that's not really going to do you much good. The public safety trunked systems in the 700MHz band will be mostly, if not 100%, digital (P25), and the PSR-310 is still an analog trunk tracker. So, even though it can technically receive the frequencies, it would not be able to decode the digital transmissions.
If you have any Motorola analog trunked systems that you'd like to track, and they either have gone through the rebanding process, or will be going, the Pro-97 cannot handle the custom rebanding tables if those are required for your system(s) (not all systems require that, even if rebanded).
I don't own the 310, but most of the comments, especially concerning the display, have been very positive. The Pro-97 is still a useful scanner, but has been out of production for several years. Radio Shack's Pro-164 is their replacement for the Pro-97. It will handle rebanded systems, but software &, of course, a pc cable is required. For the 310, the custom band plan can be entered via the keyboard or via software. It uses Object Oriented Memory Management, the same as the Pro-106 or PSR-500. Win500 will work for both the 106 (or PSR-500) and the PSR-310.
Thanks for the reply.
Can you explain rebanding? I am confused on that, I've read some posts about it but to me it seems like the frequencies change for lets say 12.5 mHz spacing to 24, would that be right? So the frequencies would be off frequency?
I've been into SW for the past 35 years now I'm getting into Scanners more.

You're confusing rebanding with the new narrowbanding requirements effective January of next year. Two entirely different issues.
Narrowbanding is the one that requires the use of less spectrum space for a given frequency. 'Rebanding' is the process where frequencies for public safety trunked systems that are in the 866.xxxx to 868.xxxx band will no longer be used. Instead, in most cases, those will be dropped 15MHz lower, to 851.xxxx ->853.xxxx. However, as some of those frequencies (the ones with a zero) were not originally expected to be used, the scanner does not recognize the 'channel number' without the custom plan. For the 310, you can enter that plan, if needed. The Pro-97 cannot accept & use it. See the two linked articles for more information.
So basically if I'm not concerned about scanning police then the radio is still useable?
I'm interested in Milair, Federal and military more than scanning police even though I do scan police but it isn't a priority.
I actually like the 97, it is more sensitive than my psr 300 even though I sold the 300 2 years ago.
it seems like police eventually will all be digital and encrypted so nobody can monitor them anymore.
I really do not want to lay out 400.00 for a radio that will be obsolete in 2 years, nor can I afford it anymore.
So basically the 97 will fit what I want it to do?

It truly depends on what you want to monitor in federal and military. Most military bases have gone digital, P-25, as well as, the feds. Very little out there to monitor analog for those two. The 97 makes a great milair scanner. I sold mine years ago and wish I had it back.

Isn't this suppose to scan the offset frequencies?
Zeromatic TuningWhenever this feature is turned on, Zeromatic ON briefly appears then zm will turn to ZM and the scanner will tune to the correct center frequency (or the step increment closest to the correct center frequency). When searching with Zeromatic off, ZM turns back to zm and the scanner will unmute faster on a detected signal but the frequency may not be the correct center frequency. Zeromatic works only in search bands SR3, SR4, SR5 and SR6.To turn Zeromatic Tuning on or off for the band, press FUNC then 0 when searching.
Even if departments move the freq's this is supposed to compensate for it....

I'm not sure what you're asking here. If you're thinking that this would compensate for rebanding or narrowbanding, that's not the purpose of this function.
The Zeromatic is there to get the scanner to stop on the correct frequency when searching, rather than stopping just before, or just after the actual frequency during a search sweep.
