Allen, One methode is to use a hub repeater and have a transceiver at the other repeaters linking to the hub. This hub can be one of the repeaters in the system (one hub with the others having tranceivers on this hub freq) or have a dedicated hub repeater on another band.
The least expensive way is one of the 4 repeaters act as the hub. The disadvantage is this one repeater must be up at all times avialable to provide the link. Often one wishes to de-link when traffic becomes heavy tying up the whole system. The other repeaters can de-link on their own, but the hub must stay on. There are many controllers that have remote base or link ports. This is now a common of many controllers. I sell a controller that is probably one of the least expensive with a remote base port. It is a repeater controller with a controlable link/remote base ment to be connected to a transceiver for linking. The link radio, no matter which controller you get, does not have to be full duplex and will be seen by the hub repeater as simply another user. Linked repeater gets input keys link and when link gets input keys repeater. The repeater still acts on its own as a full duplexed repeater. Many have had great success doing this and has been done in USA for few decades now. Another method that has some success is Echolink or IRLP using the internet. In the transceiver method the link must be able to get into the hub. If distance is a problem then using the internet is another choice. It of course will require an internet connection at the repeater(s). 73, ron, n9ee/r --- In Repeater-Builder@yahoogroups.com, "allenittiyavira" <[EMAIL PROTECTED]> wrote: > > Hello all, > I am Allen, senior radio technician, working in Africa, new member. > > I have extensive experience in trunking systems, but not very good > with conventional. > > I would like to know the best method to link 4 repeaters (conventional) > to work as one channel.
