Plus the walkie talkie being used for the transmitter will suffer extreme heat build up under use from a few users on the system. I have a baofeng uc5r and I keyed down for 1 minute and the the inside chassis was very hot. Use mobile radios with large heat sink and a fan for better dependability.
A word of advice, don't use walkie talkies for repeaters. They may work for temporary installations, but as a permanent use no way. I cant see how you could keep desense out of the receiver being next to the transmitter.being used
