Hi, there are a few scanners @ a few ways to monitor the OPP.
1) You can buy a digital scanner. Most of the OPP comms are not encypted but digital.
A few common radios: Pro96 on the Radio Shack side & Unidens 396D, 296 and 250 to give an example of portable ones.
You can purchase these scanners at scannermaster.com on line or if you prefer canadian
Durham radio and radioworld in the NW of T.O.
Google their websites for a look.
These scanners are not cheap.
If & is ahuge issue you can always get a non-digital scanner and punch in conventional repeater frequencies but you have to be close enough. to the action to receive these.
Ipersonally have an older digital scanner (296) and it works fine
