You have a bad detector in the radio. Needs serviced. Change the bad detector diode and it should work. Good Luck

SOURCE: wont change channels

First, try resetting the faceplate CPU by shorting the proper pins on the faceplate to radio connector on the back of the faceplate with a piece of wire... They are marked on the connector, if this fixes it for you, enjoy!

If that doesn't work, then remove the back cover of the faceplate and check the faceplate connector itself for bad solder joints. As a matter of fact, check the entire radio for bad solder joints before looking any further.

I bought one of these radios a short time ago; Everything worked except for LSB.

I was told by the radio shop I bought it from that I'd have to wait until June to get it fixed, so I opened it up myself to see if it was something easy to find/fix, since I felt that if it was anything major it wouldn't be able to get AM or USB either.



In my case, I found bad solder joints on the faceplate connectors and a bad solder joint on one of transistors attached to the heatsink.

Once I fixed those two things, it's been a great little radio.

Be sure to reset the faeplate after resoldering and assembling, to clear any errors from the CPU.

Running most any regular cb, including this one barefoot (with no kicker), having a good antenna, set up with a good ground plane or a no-goundplane antenna, good coax; basically everything in good working order, you can usually bank on about 4 to 5 miles crisp and clear, and at least 6 to 10 miles fairly clear. Of course the further out you get it will start to fade out.

Some radios do better than others, but those are the general numbers I have seen in my years of experience.

My Midland walkie talkie quits transmitting about 3 seconds after I start transmitting


It is more likely a power issue. PTT switches do not normally cause a short circuit. Check the batteries, swap the batteries and see if that helps. Radios take a great deal more power to transmit than turn on or receive. If not the battery, try a low voltage battery, such as a cordless phone battery. If it still occurs, check your warrany and send it back to the factory.

How can i modify the midland 75-822 for more channels?


Modding your CB for more channels puts the radio into Ham bands which you need a license to transmit on, also modding a CB violates FCC part 95 rules and is therefor illegal to transmit with and the hams report most illegal transmitting on there band
