I can't speak for Uniden, but as it was initially marketed as a scanner for "newbies" and there is little of anything of use to the "newbie" above 956MHz, it may not be doable.
Just out of curiosity, what is there of interest up there where you are? I forget what's above 900 MHz trunking/short range mics. Don't have anything interesting in that neighborhood here.

Gordie, people have mentioned the GRE scanners and Uniden scanners.
The HP1 and the PSR800 similiar in that you pick what you want to hear. This sites database is yours to scan. I.E. If you live in Ottawa you can bring up any frequency and system listed and there you go.
Someone mentioned that the PSR800 can handle some new-fangled P25 technology that the Home Patrol cannot. This might be a reason to go with the GRE(PSR800) scanner.
The other digital scanners that people listend like the GRE500 (I think) and the Uniden 396XT's are great but you are going to have to program them. The Uniden XT scanners are amazing but it takes a little know how to program them at first. If you can work with spreadsheets you can learn how to program the radios with software provided or bought from ARC.
To me, having a scanner that allows you to scan above 956 or one with the FM band should not be a deal maker or breaker.
