good afternoon I have a problem with a Motorola Dr3000 vhf (xpr8300) the repeater turns on, goes through its entire control cycle and goes into standby, the problem is that it does not transmit or receive, I checked the programming and everything is in order, it does not transmit or receive in either digital or analog. I checked the cables but it does not seem to have any problem, the LEDs remain on in standby, the Power ones and the analog and digital ones, the tx and rx LEDs do not light up when I try to excite it with a radio. do you have any advice? thanks
