Either the mike or cable is bad or you have a problem in the transmit speech amplifier or modulator.

The only think i can think of at the moment from using cb's and now amateur radios is that the antenna antenuator is on.
adjust that and see if it helps... also plug an external speaker into the back and see if you get better volume from that.

Why does the uniden grant go into transmit mode when turned on


if this happens without a mic attached, it is common for the tx/rx switching transistor to fail

No sound on left front speaker


you need to set up the individual volume levels for each speaker.
do a sound test tone which will check for a signal from each speaker.
if you hear the speakers at different volumes you know you need to adjust the ones that are too weak. hope this helps

Uniden grant cb radio


You can't You need a spectrum analyzer to set the frequency correctly. This is not something you can do by ear. When you go poking around inside with a screw driver, you can mess up the entire radio.One adjustment will affect other adjustments. That's why there are radio repair shops. Just take it to one.

Turned up full volume u can only just hear sound if ear right to it was working fine then the volume just ******** out


It could be the mic plug. uniden is known for the issue where the wires inside the mix plug break at the solder joints.

When the RX wire breaks, you will loose receive because the radio will not go into receive mode. But you can usually hear it ever so slightly if you crank the volume.

Other issue that may cause this. No radio activity, (unless you hear radio activity low and not static)

poor feed line or antenna.

I would try a different mic that is known to work.

No Sound - LCD Volume says 99


Found a solution that works. Power down the receiver. Unplug it from the wall. Wait 10 minutes. Plug it back in and power it back up. Worked like a champ to fix this exact problem with my TX-SR601.

No sound


Check first if theres a speaker cutoff in the menu of the set or the back of the set. Next see if theres a headphone jack and plug in a set of phones to see if you get sound. If you do a connection on the jack is bad. if you put youe ear right next to the speaker and hear a little background noise or a little sound then its probably in the volume control curcuit. if you hear nothing at all its the audio output IC or the speaker itself is defective. Good Luck
