Dear friends
Any one knows is there any repeater in Motorola that can connect to two deferent link repeaters.Like COUGAR (made in uk and it is miltery use )radio have.
Thanks

so you mean like a repeater controller that cross connects two repeaters? [edited for relevancy]NHRC makes some Amateur products that will do that. . .

It is just like , suppose you can transmit up to 50km only by using repeater.if you want go more caverage you can not use another repeater.Becouse two repeaters gets loop each other.so to link that two repeaters you must use other repeater which coupled to the first repeater which transmit in deferent frequency call link. but link should have qulity it transmit to second repeater by using directional antenna that only when coupled(first repeater) repeater received the signal. And other way when it (link) receved from second repeater it give massege to first repeater to transmit. that time link will not transmit
So my idea is couple two inks to one repeater so when repeater is functioning that two link will transmit in deferent frequncies to the to the two repeaters

Alright, I'm dizzy.

If I am translating this correctly, you want to have two seperate repeaters on seperate frequencies and something in the middle to link them.

You shouldn't link two repeaters using an over-the-air method because the repeater trail will cause them to ping-pong back and fourth and not stop until someone unplugs it. Also, you will always have really bad front end clipping. What you are asking CAN be done but it is not recommended. Repeaters really need to be linked by hardwire to work properly.

i translated that a little differently. i thought he was asking about using a 2nd repeater to cover for wide area coverage. 50 km is what 30-something miles? too close to operate on the same repeater pair, so I hope he's looking at operating at totally different frequencies. i'm thinking maybe we're just talking about a bi-directional patch from one repeater to the other for re-broadcast on another frequency for either a separate group of users or the same group that would travel out and switch to the proper channel for that area.

He's probably talking about linking two repeaters together. Hams do it all the time like when they link two VHF repeaters by using those "worthless" 403-433 Maxtracs in the 420 range.
