Michael.....Icom radios are very voltage dependent...My 7000 will transmit with the truck shut off about two or three times for short periods, then the radio shuts down.
?? Cut the power to 30 or 40 percent and its all good......Run the engine while transmitting and there's never a problem at full power.
? I had the same issue with my? Ic 706, and an Icom dual bander in the mobile.? Awg 10 wire feeding the radios so plenty of cutrrent....
Stick a voltmeter inline and you will see the voltage drop....about the only thing you can do is operate at less than full power.
?Good Luck

Anyone had this issue.? Powered by a LiPo battery and using a 1/4 vertical with a wolf river coil with an swr less than 1.5.? When transmitting CW at 100 W, the unit will shut down.? If I turn down the power to 25 W this won't happen.? Doesnt happen on 20m. Any ideas?
