Radio turns on , channels change, but no sound or squelch..

check squelch

On all channels, or on one channel ? Some channels are "birdie" channels, check your user manual. Others are problem channels receiving false signals from computers, monitors, receivers, internet equipment, FAX machines, etc. If your in conventional mode, if in Digital mode the squelch is set by the processor, and I don't believe the squelch has any effect in that mode.

first of all is it set up to a antenna source? if so then turn the squelch nob counter clockwise all the way, then turn the device on. next start at channel one and slowly turn the squelch clockwise until the pin moves or you hear static. then surf the channels adjusting the squelch to to that static point until you find your active station. from there to cancel static between transmissions turn the squelch so that it is just below the static marker.

Turn the volume up about 1/3, the squelch off or fully counterclockwise. You should now hear static or talking,if not something is wrong with the radio. As a last resort change to channel 19 and see if it is dead as well. None of this is valid unless you have a proper antenna connection. When you are receiving then adjust the volume to a comfortable level and turn the squelch up, clockwise, until it just mutes when no one is talking. The higher the squelch the stronger the signal has to be to be heard.
Good Luck,

You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.

Hello,
You can change the squelch setting with the user buttons, You could set a PL or DPL but the other radio's that you talk to will need the same setting.
Go here for the manual:

I have the same walkie talkies and on mine I can hold down the mode/lock button and it will come off of the Rx mode. Also, you should be able to press the talk button and it will come off of the Rx mode.

Hello Are You using the correct antenna?,when you turn the squelch down do you hear static sound?, are you using squelch codes? if it is just a CB radio that works on Citizen Band (11 Mts) this radios does not have squelch codes.

Let me know the brand, model of the radio.

Hi Tucaraca.

With the radio OFF, switch to CHANNEL 1, press the SQUELCH and the PTT at the same time. Turn ON the power switch while keeping the PTT and SQUELCH until the LED indicator turns RED.

Release the buttons and then press the PTT to CHANGE the FREQUENCY.

Press the PTT once each time until you get to the right frequency you desire. The 8 standard frequencies are as follows: 464.500, 464.5500, 467.7625, 467.8125, 467.8500, 467.8750,467.9000 and 467.9250 MHz. Once you get to the frequency you use, wait a few seconds and listen for the confirmation tone. Each frequency has a different confirmation tone so take note in case you need to program a second radio.

After you hear the confirmation tone, press the SQUELCH to confirm, and then press the SQUELCH again to lock the new frequency. Wait until the LED turns off, then switch off your radio.

Same procedure for CHANNEL 2.

WARNING: You must be legally licensed to use any frequency on any PLMRS such as the TK-3100 series. You must also apply for FREQUENCY COORDINATION and submit FCC form 601. FCC can impose steep fines and imprisonment if they catch anyone using an unlicensed radio on a controlled frequency. Visit FCC.GOV for more information.

Do you hear the Beeps on the speaker? Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0". Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.
