Have this mobile radio i will be looking at soon when i get it. It works perfectly, apparently how ever, it constantly draws 6 amps when turned off which is a lot more than it should be drawing just for the RX mode idle state. And no over load protection ever kicks in, in essence, it drains the battery in the car. My guess is, it maybe a leaky reverse diode or cap that just isn't shorting enough to cause protection over loads to take place. We'll see when we get the radio on our bench.
