Based on your post/description, you can hear others (RX-receive) OK but "...they cannot hear...very well..." then the problem is with the TX or transmit.

If the problem only is when the others are far from you, then it is possible that you have a defective final or at least a defective antenna/connector/solder joint. If on the other hand, the problem is present whether near or far, then perhaps your problem could be the modulation circuitry (which includes the mic). In some instances, it may be due to the Interference Elimination that you and/or your friends are using. At other times, it may be because of the battery no longer charging completely.

In any event, you would probably need the services of a qualified communications technician since this would involve opening the unit, familiarity with electronic components and circuitry, use of a DVM & a soldering iron or hot air blower.

You have to consider the cost or repair and the downtime. In most instances the cost of repair would just be a little lower compared to buying a new unit.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

SOURCE: motorola t5100 cant hear the other person talking into the radio

Check to see you have the radios set to the same frequency and interference eliminator code as one another. This would be the most likely cause.

Here is a link to the owners manual

SOURCE: Can't hear each other when talking?

Here is a copy of the user manual: Double check the programming of your frequency and interference eliminator code.

Then you might check your Qt filter and your call tones. Set both to the zero (off) position and see if you have the same issue.

What do CTCSS and DCS means

CTCSS is a subaudio (<300Hz) tone that is broadcast when you transmit on a radio. If another radio is set to receive that tone, then the squelch will open and he will hear your transmission. Having said that, any other radio that does not have CTCSS set at all will also hear your transmission, so all it does is for the receiver to hear less of others talking. DCS is the same except that CTCSS sends out a continuous tone, DCS sends out a string of tones. This allows more "channels" to be allocated, but still ,everyone is using the same frequency

How to change the squelch on mtx8000

You can always have a radio receive. To transmit require an FCC License, and you need authorization to "Talk" to Public Safety. There are large fines and possible jail time to talk on channels you are not authorized for, especially Public Safety. Sadly, your radio is programmed to monitor only when the button is held down. The frequencies in your area working are a lucky coincidence. Take it to an Authorized Motorola Dealer and pay to have it reprogrammed. Radio is not field programmable. Hold onto your wallet, they are expensive to have programmed. You should have bought a high end digital scanner.

When I depress the transmit button the cb puts a squel out to other radios on the same channel yet I have no problem hearing transmissions from the other radios

It sounds like the mic either has a problem, or its wired incorrectly for that radio.

Try a new mic, and make sure it's wired for that radio.

Also, if you have talk back then it's too loud, or your mic gain is too high.

The type of radio would help me know weather or not it could be the mic wiring.

See if the one radio that doesn't hear the other has a PL tone programmed into it. If both radios are not programmed to the same PL tone, then one will not hear the other. Consult your owner's manual on how to do this.

I can rx transmissions but they can't hear me.

Check the settings of both your interference code eliminator and your Qt filter (if your model has one). These codes need to match the other radios exactly. If the other radios have a Qt filter and your unit does not, then the Qt filter would need to be shut off on the other units.

Motorola t6500

You need to set your interference eliminator code to zero, and your Qt filter to zero also. Here is a link to the owners manual:

What is happening is your T6500 is set to ignore radios which do not match the same code. The fact your Cobras can hear the T6500 indicates they are set with their interference eliminator turned off (aka no code).

A similar occurance will happen if the Qt filter is set to anything but zero. The Qt filter is unique to Motorola. These features are beneficial when you are in a high radio traffic area and you want to block out hearing other people. But in your situation, you are mixing radios, and the easiest way to make them match is to turn off the special features (aka set them to zero).

I can hear people talking, but they can't hear me, or they say I sound like an alien

Check to see if the meter needle is swinging backwards when you key up. If it does your final may be bad. If the needle goes forward and others say they see your keying up but no sound your audio chip may be bad; especially if you have tried so many mics and antennas. If your radio has a swr warning light and it comes on this could extremely limit your range and others may not hear you and contiued use will damage your radio. Good luck!!!
