okay i was hearing today on fleetnet zone 1 at the guelph tower. police common TG and different agencies were calling other agencies for radio tests. now my question is how is the transmission transmitted over the long distance and be able to be heard on ALL towers? for example you have someone in Orillia radioing Guelph PD or vice versa. Is the actual radio signal being sent to the local fleetnet tower(i.e Guelph Main) and then that tower rebroadcasting it DIRECTLY to The orillia fleetnet tower? or does it travel to that tower and all others by different means?
