Change frecvency midland alan 42 multi - Midland Radio Communications

do you have a users manual,it should say in the specifications section

could be a bad IC chip

There is...I found one in german, same radio but under the name of Alan-42. Easily translated using google. I was using a lobrary computer and was unable to print or save it, but it's ouut there.

Midland like other companies goes where the cost is lowest and they also in are related to Alan who makes ham radios as well---Korea makes better stuff than China and some other countries.

hello there your problem is simple the final transistors have blown as you have no audio an audio transistor is also required best leave it to the pros to repair goodluck

Check for loose buttons, could be something loose inside, if its changing on its own when its moving around could be from vibration that something has come loose.

When parked just try shaking the mic first if that doesnt do it shake the cb itself and see if the problem persists
