The main reason I switched from my 19 was because it went back to channel 1 each time the power was cut. I don't care for direct to battery stuff unless the device really needs the amps so I like my CB to fire up with the ignition.
Anyway, with the help of a CB forum member I figured a way to mount a battery in the radio so it holds the channel. It's really friggin' simple and anyone could do it.
I'll post a pic if anyone is still running a little Cobra and wants to fix it.
