I guess we can find any information we want on google ... may as well close this forum then - or have every single person not answer a question and just redirect them to google ....

That may be taking it to the extreme, but a lot of people seem to be lazy & rely others doing the 'Googling' for them.

Although, I think that this is relevant & interesting question that will benefit others.

Yes, many people are very lazy and if someone else is able or silly enough to do their work for them then they will sit back and just let it all happen. This is exactly what I experienced in the work place and it is all too common on forums etc. Time for the 'lazy people' of the world to get their act together and fend for themselves.
My philosophy in life has always been along the lines that if I can't do it or find the answer to a problem then as a last (LAST) resort I might ask someone else.

Ian asked a simple question and V8 Troopie answered it, the rest didn't have to do anything at all so why insult the poor bugger.

This is why people don't ask for info on forums.

In a nutshell without getting too testicle, A is you,B is the repeater and C is your mate, you transmit from A to B on a frequency,B transmits to C on another frequency at the same time,as your radio has a different transmit and receive frequency on Duplex and a single frequency on simplex 'ie car to car' this is how it works and vice versa. you will hear a tail come back from the repeater when you release your mic button. this is an acknowledge from the repeater.you have selcall and CTCSS and other things but thats another story, hope this makes sense. cheers Paul (ex gov radio tech)

Yep.

On simplex, say channel 8, your UHF transmits/receives on Ch8 (just like any other channel),
Here's where it get's confusing, On duplex(repeater), your UHF receives channel 8 but transmits on CH 38, The repeater only recieves on channel 38 but converts the outgoing signal back to CH 8,
This is why when travelling in convoy it is inportant to stay off channels 1-9 and 31-39, Even if your set is in simplex mode transmiting on 31-39 (depending on what the local repeater channel is) you will trip the repeater, and your idle chitchat will annoy others for miles.
NEVER use CH 5 or 35 unless it's an emergency, these are designated emergency use channels.

My understanding is that the repeater tower is placed up high and has a stronger signal, so it basically re transmits your message. We can pick up Race control in Alice Springs from down at the Finke end of the Desert Race (220km) through a repeater. We would normally only have a 5km range.
