Since the radio cannot transmit on Weather bands, there is no need for the radio to detect if it is transmitting when receiving weather.
In CB mode (on CB channels) the radio will mute when transmitting. So... a guess is that it is muting, or transmitting all the time in CB mode. Check for a mic problem by removing the Mic from the radio ... if it receives CB with no mic connected, then there is an issue with the mic. Otherwise, unless the unit is in PA mode (public address mode) it is likely something internal and beyond the scope of this service.
is it a total no TX. or just not getting out very far.?
could have a broken mic wire. or the CB / PA switch may be in a wierd spot try moving it.. are you getting the Correct RX frequency on the channels.. ie are you getting channel 20 on acutal ch 20. and if you switch to ch. 6 are you getting ch 6? if you could explain more..
sorry disregaurd the wire colors.. on last post 1. Ground
Shield
2. Audio
3. Transmit
4. Receive
5. CH. Up
6. CH. Down wires can be any color. just matters what pin and pole of the switch they are one.
The Midland radio you have is NOT capable of FM transmit & receive. It is a Citizen's Band radio that operates on channels 1 thru 40 that are assigned to the 26.965-27.405 MHz frequency range. These are the standard 40 Ch CB frequencies in the U.S. (and may not be legal for use in other parts of the world without a license from your country's communications authorities). It also offers Weather Band reception - again these are US frequencies that may or may not even be used at all in the UK. Since the radio only displays a channel number, you don't actually know the frequency you're monitoring or transmitting on. Your friends on CH 5 may be in a completely different band.
Even if they are on the same frequency, the fact that they are operating in FM mode means that you would hear something - but it may not be intelligible - and the same would be for them listening to you transmit in AM mode. If you could have them switch their radio to AM, all would be fine. I suspect they use FM as there is much less static when compared to AM.
If they won't change to FM, you'll either have to stop trying to talk to them or buy a radio capable of FM (and make sure it has the same frequencies as theirs!).
Hi, my name is John. Take the cover off the unit, and check for broken trace or loose solder joints around this area, ...hope this was helpful..Rate this solution on the four thumbs-up.....John
here is the info you asked for the following is the correct wiring.

Sounds like the PLL circuit....... no channel synthesizer will kill the transmit and receive...... bad crystal or IC could be at fault or if someone has attempted to add more channels could also be cause.
