Are you sure that you're on the AM mode? It sounds more like you're on LSB or USB. If you are on AM, the problem may be the power control (VR6) inside the radio.

SOURCE: Cobra 148 won't stay on frequency, same frequency on all channels

If you have a frequency counter, and a set of TV repair tools,( a set of special screwdrivers) You can tune the transmit on it. I would not do this unless you are skilled in such things.

The easy thing to do is take it to a cb shop. Usually you can find them at truck stops. They usually charge $30 for an alignment.

If you think you can handle it, I can try to talk you through it.

You watch this video and check your power output specially on those channel at chich not transmitting, if there is no power at those channel it mean that you program out of range radio band frequency, so you check your frequency and correct it.
