Was up near Sudbury and didn't pick up any 700MHz from the cars. Looks like they still are old school antennas also on the cars

Will the other VHF Simplex (Investigative) and UHF Tactical and simplex frequencies be also changing to 700 MHz?

From an Advanced Care Medic buddy, they've just got done their new radio training. And were told 100% encrypted so nobody can listen in and they can give more medical info over the radio.

Sure will be. ALL VR's will be converted to 700. OPP, EMS, MTO, MNR so on and on.
All the current VHF simplex stuff will stay they same but converted to P25 and encrypted
They're already like that. With partial e. What about the UHF Tactical simplex frequencies? The ones listed at the bottom of this page. Will they be going to 700 MHz or staying put?

Sorry, but I'm late to this LMRN change up.
Do I understand correctly that 138 and 800MHz will be used? The current 140's dropped?
I can see 138 working where I am, but not 800.
Cheers

More or less.. Same set of VHF frequencies for the mobile radios and tower sites. No more UHF vehicle repeater frequencies. Them are changed to 700 MHz
Vehicle radios are VHF still, portable radios are now 700 MHz.

I am guessing the reason for staying with VHF. The lower the frequency the better the distance and the same amount of towers?

I made a few calls and there seems to be a high level of confusion over encryption. Some think that P25 Phase 2 IS the encryption. Slapping encryption on top of P25/2 will hurt coverage. I don't care what they say. Even just P25/2 you need a great S/N ratio for sync. AES Key system could be deployed but does not fall into the description. DES is more likely. This would allow active key changes to be sent over the air rather than AES radio reprogramming. If DES is used some "smarty pants" will come up with a key grabber. But those waters are starting to get murky grey.

It'll be AES, guaranteed. OTAR also works with AES, not just DES, so that isn't an issue either. And encryption will not hurt coverage, but that's a debate to be had in a different thread
In car repeaters will be 700MHz and sites will be VHF.
As Forts has already said, the system will be using AES.

Are they analog only or are they also transmitting digital?
Analog at the moment.
I was speaking with an OPP officer and they had a 700/800 radio with GPS but it sounded digital. My G5 Unication on the 700MHz channel sounds like crap.

New system will use the same VHF frequencies that are in use on the FleetNet current system. Vehicle repeaters/Beat repeaters will move from UHF to 700MHz
