Note:1.the repeater have MIC ,but it not standard accessories

         2.the repeater just can do 10mhz ,you should choose 10mhz from 400-490mhz ,like 410-420mhz,422-432mhz,445-455mhz and so on.

         3.the repeater software just can change channels frequency and CTCSS .but the factory should be in factory setting . if the repeater is finished ,you will can not change the frequency(like 410-420mhz,422-432mhz).

          4.the repeater need antenna .the antenna need to put in the highest place ,the signal will be good.

         5.the repeater need a cable to contact the antenna .the cable can not too long ,the cable will reduce the repeater power.

cable need -9 (is good ).
