This is 1 thing I'd like to learn more about. How do repeater stations work? I presume they r channel specific???....hence y u need to know which ones r where?

Channel 1 - 476.425 Mhz to Channel 8 - 476.600 Mhz & Channel 31 - 477.175 Mhz to Channel 38 - 477.477.350 FM (Frequecny Modulation) just like the commercial FM radio stations.

Repeater channels work in pairs ie: 1 to 31 , 2 to 32 , up to 8 to 38, the lower number is what you put your radio. Then press the DUP or REPT button on your radio. The display will not change when you are in "Repeater Mode."

In most cases you will have a range of about 30Kms to 100Kms on the Repeater in your area. This range will depend on the location of the Repeater, the height it is above the ground and the clear view in all directions. You will find the range decreased in the direction of obstacles. A mountain ridge or a large hill in that direction will reduce the coverage area also.

One more thing - one repeater can not talk to another repeater to extend your range.

Each repeater has its own target area and in some cases another repeater on another channel will overlap the area you are in, so if you travel around Australia a lot you will need a repeater list for that state. Within each state you will find the the same channel will be used over and over a few times. As I mentioned above, they are all stand alone devices and are not connected to each other to make a larger coverage area.

Repeaters use two channels to operate. When you push your DUP or REPT button on your radio it will do the changeover each time you push and release the PTT button on the side of your Microphone.

When you press the PTT button the radio internals will switch the transmitter up 30 channels to the input channel. ie - channel 1 on your radio will now transmit on channel 31 but the display will not change to 31, then when you release the button the radio's receiver will come back to channel 1.

Hope that helped,

Had this happen on the weekend... needed to call out but couldnt get a hold of anyone as we were deep in the valley and couldnt get anyone on a repeater channel.... If in dire emergency, you will need to get to the top of a hill if possible... (this will also help with the chopper rescue that you are probably calling for....)

I have thought about the possibility of having a small gel cell maybe, that you could use in that sort of situation. You would obviously set it up with the right connectors for your radio(s) ( HF and UHF ) and maybe a bag with a shoulder strap, or just a strong back pack to carry it all up to the top of the hill easily. Of course the other requirement would be to research the best way to set up the aerial. Would you need a length, or lengths, of cable to act as a ground plane. This is where my knowledge is lacking.

How near to a repeater station do you need to be ( obstacles etc not withstanding ) to be able to transmit / receive effectively. Looking at the repeater stations list published above, there seems to be a lot of distance between them. An example might be if you were in the Drouin ( Vict ) area, you have the Walhalla station many miles to the east, a couple even further north etc. Suppose I am just trying to understand how they work a bit more.
Any info would be great.
Thanks

Depends on the surrounding terrain and the height of the repeater station, the radio path makes the biggest difference. From a high hill you may be able to access a repeater over 100km away but from a lower location it may not be available. Vhf/Uhf has always been regarded as line of sight meaning if you can see the repeater you should be able to work it.
Actually the signal even on uhf does go beyond line of sight but with so many variables in the equation such as antenna type and gain then how good the installation is it is very hard to have hard and fast rules for range.

the uhf cb repeaters are almost a thing of the past although with the new 80 ch they may come back , but i doubt it in the metro areas , the seem to attract oxygen theifs and all that goes with it , i used to own and operate the chan 8 repeater at Arthur's seat just south of melbourne . and got rid of it , as i was sick of running out and fixing things for morons and this is the problem with the band ,

to own and operate the repeaters is a very costly deal , license fees site fees equipment etc etc , at the end of the day it just is not worth it , un less you run pirate , and we wont go there

most of the ones in metro melb are gone , some come and go . the outer areas some still remain

Yeah I know how you feel I was involved with a PRS (UHF CB) repeater here but to be quite honest I would never go to the trouble of being involved in one again. When you get to a stage that you have to turn your own radio off because of having visitors in the car when you are on your own repeater channel it is just a complete waste of time. I took over looking after the repeater when the owner went to Singapore for three months and I started to turn the repeater off when the behaviour got out of hand. Behaviour did actually start to improve after that and some of the regulars started to police things better themselves.
These days I have put my time and effort into ham repeaters (two metre and 70cm) and they are a lot more rewarding and less stressfull to operate.
