I think rusty15 is looking for information about Saskatchewan Department of Highways (SDH) and not Saskatchewan Highway Patrol (SHP).
SHP is on PPSTN and is encrypted.
SDH is using encrypted NXDN radios on their VHF channel.
Neither of these agencies can be monitored with a scanner.
This is Saskatchewan !
It doesn't cost anything and doesn't hurt anything, so there is really no reason not to, I guess. It's like WiFi, you can run it unencrypted, and it used to be somewhat common to do so, but if you are setting it up, why wouldn't you?That makes sense. Still the encryption part however doesn't. My theory is that they know people can listen in on them and CHOOSE to have the encryption option on. Stil, what's so secretive about fixing roads that they choose to encrypt? I don't understand. There is lots of things that government services don't want the public hearing even if its as small as banter talk over the radios.
cries in radio tech
Someone get that radio a wet nap (and maybe a can of air).
