G'day Nick,
Good work.
Have you considered using VKLink for your linking instead of RF?
http://www.vklink.com.au/We currently have 2 x 6m repeaters linked full time.
Three sites in the South of Tasmania are "voted" and simulcast on the same frequency, then linked to the North via VKLink all using the same system.
You can view status of "nodes" here -
http://status.vklink.com.au/Status of the voted stations RSSI in real time here -
http://hh.vk7.com.au:83/voter.php?node=1727In VK3 they have linking happening from the SA border > Mildura > Swan Hill > Balranald > Wodonga. Any of these links can be dropped/re-established somewhere else, even to VK7. In fact every Monday night at 6:30pm we link almost all of these together for a TechNet via hub.
This months WIA magazine has an article on the voted/simulcast repeater here.
If you need more information please contact me.
Regards
Hayden VK7HH
