I listened to the new P25 digital system for about 3 months before it went encrypted, and yes there were complaints both from officers and dispatch about it. And yes in buildings as well, i've heard it mentioned several times specifically from officers saying "no reception at all in this building".
I wonder how Toronto Fire is gonna handle it. I know they currently use a mobile repeater in the Distric Chief's van for buildings with bad reception and underground work. Will they eventually upgrade those mobile repeaters to digital?
I also wonder how TPS is handling subway calls now. Before they had analog (non trunked) subway channels.
I would take the CTCSS tones off all the old 400 mhz fire ground channels and same with the police and ems subway channels, you might find P25 on them. Toronto fire was doing a lot of testing with mobile repeaters and going through all the fire ground channels recently.
One thing that came up was "waiting for the repeater to warm up", guess those things just don't turn on instantly.
They'd almost have to do it like London and have a repeater in every engine, the district chief can't always be at every call and sometime things happen quickly at a scene.
