Question about Cobra PR-245/2 (7 Channels) 2-Way Radio
No transmit no recive meter lights don,t burn chanel lights do burn
I don't know this radio individually, but heres the common thing that happens:
Sounds to me like the 8 volt regulator chip has blown after overvoltage. I expect the power supply has gone too, putting 18+ volts into the radio.
Repair the power supply. (Check its 13-13.8 Volts).
Then check the regulator (7808) is putting out anything, should be middle pin ground then 13V one side and 8V the other, if nothing, its blown. Replace it if gone.
Hopefully thats all thats gone and it should work again.
