1. OK, so what is the point of a radio system, where the base and mobile tranmit on a different frequency? I understand that a repeaer system HAS to do this, but I am just talking a simplex system. Why not just license one frequency, it's cheaper and all the units can hear the other traffic from cars? How does it work? I mean, how do the units hear the mobile unit if they're RX on a different frequnecy!
2. Sometimes with a radio system, the base radio or coucil will hit the repeater with other agencies however sometimes the repeater just shuts of at the end of their TX. Why is this? And what is the difference? I never notice this on trunking systems, just conventional.
3. Why do agencies still use frequencies without reapeaters? I can never hear the mobiles, only the dispatcher so does that mean the other mobile units can't hear them either?
sORRY, just net to all this radio stuff! thanks soooo much!
