When I key the mic, the radio restarts. When I unplug the CI-V cable from the rear connector, the radio shuts off and a clicking noise is heard. The same thing happens when I unplug the USB connector from my Mac. Both go to a microHam IC13 controller that I use with MLDX software to interface with the radio. What is the symptom for blown finals? It does receive on all bands but of course this has nothing to do with transmitting. Thanks.
