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

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.

SOURCE: How far can that midland

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.

Midland 75-785 gets very hot within minutes of powering on


The radio is either stuck in transmit or the RF power output section has a short in it. If there is no RECEIVE audio and the squelch is open, and the radio is not in transmit, the chances are pretty good that the audio power amplifier is shot.

Are you on the same channels? Are you on a repeater setting? What are your squelch settings?Are your batteries fully charged? Power is needed on transmit, not so much on receive

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 many watts do midland walkie talkie xt20 have?


These are FRS/GMRS (Family Radio Service/ General Mobile Radio Service) radios. The legal power limit for FRS is 500 milliwatts - or 1/2 watt. GMRS on the other hand is limited to a much higher 50 watt level. The wattage you transmit determines if you need to have a GMRS license. Most GMRS radios are in the .5- 5 watt range however.

The likelihood of your XT20 being a 1/2 watt out on both FRS & GMRS is very good. For Midland (or anyone else for that matter) to produce a radio with a 1 watt output that can run on just 3 "AAA" batteries would be quite the feat! If Midland did do this, the radio's battery life would extremely short. To balance the needs of light weight and battery life, output power needs to be reduced.

Claims of 20 miles is crazy. If you had these radios on mountain tops 20 miles apart - with a clear line of sight between them - MAYBE - you could hear one on the other. This would need to be done under only the most ideal conditions. The actual distance you can expect to get out of a pair of any brand FRS radios in "real world" conditions (line of sight blocked by trees and buildings) is about a mile.

An FRS/GMRS radio limited to 1/2 watt output when used on a GMRS frequency that is close enough to access a GMRS repeater system could easily cover 20+ miles. The key here is having a license and access to the repeater. Repeater owners take a dim view of unlicensed users access their repeater.

Channels 1 thru 7 are FRS and GMRS. That is, if transmitting .5 watts, you can use it as FRS. If transmitting more than .5 watts, you will need a valid GMRS license.

Channels 8 - 14 are expressly for FRS. Only .5 watts transmit power is permitted.

Channels 15 - 22 are expressly for GMRS at any transmit power up to 50 watts. Even if transmitting .5 watts, you MUST have a valid GMRS license on these frequencies.

I know - more infor than you wanted and no vclear cut number for wattage - but there's no info on these radios on Midland's site or anywhere else that I could find. Good luck!

We have a problem with one of the hand sets. It will not transmit. The other one works fine. The TX will come on, and we can hear it coming across the problem hand set. The problem hand set shows the RX ....



  • Check the settings of the CTCSS tones on both radios and make sure they are the same. It would seem if you are hearing a transmission from the other radio but cannot transmit out of that same radio than that radio is malfunctioning. It may be time for a new pair.
