Need help with repeater setup for across town communications

[losangelescop]

Hi everyone, just looking for some advice on the best way to work a repeater system. I live in Australia, and my city is approx. 45.5 square miles. we are using Motorola GP328 portable radios (Australia's version of the HT750). where my friends house sits, i can just get his signal in a certain part of my back yard, i want to get a repeater set up atop one of our houses so we have a great, clear communication range, but it would also be awesome if we could spread out a little more and use the repeater to work all across our city and maybe even a little into neighboring cities/counties. (kinda like wat public safety ppl do so they can talk across town). The frequencies we are using are the public frequencies, UHF, a select few of the 40 available. these sit somewhere between 476.425-477.400Mhz. if possible i would like to get or build a motorola repeater that can accomodate all 40 of our public frequencies so we can change channel if the lines are busy and/or accomodate for any future changes incase we decide to change which of these 40 channels we operate on. have i even got the right idea here, is a repeater useful in this kind of situation? i know i wrote a tonne-load of crap im sorry any help would be appreciated a lot. thanks ppl

Ok - There are already 3 topics started by you on the same subject. I'm locking this one.

Keep it in one thread, and if people are able to help, they can reply in that thread.

There's no reason to start 10 different threads on the same topic.

PLEASE

Read the FAQ as well as any sticky/announcments that are on the board before you post again.
