Re: uniden grant xl no speaker sound
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.

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
i cant afford 20 dollars to fix that radio your add said free i am laid off the old grant will have to waite i am not a teck have no idea what is wrong thank you for your time sorry to bother you ihave a good ole cobra29 that i talk on now grandadmac50@ yahoo.comm
Check around the pcboard where the dc goes to the board, sometimes the foil will burn. Also chec the transformer, Chec that one of the wires did not come off the plug in the back. When you replaced the protection diode did it blow again? If not keep checking for opens on the pc board. When you said it was dead do you mean no lights at all or no tx and rx?
No audio out / low audio out....This is a constant problem with the COBRA 148 gtl....to get a good level of volume replace the
electro caps ...start around the two speaker wires and work back from there. I'm in the process of rebuilding a 148 gtl and have found caps that are leaky and dried out...after replacing nine the volume went up to a good level...now i need to fix the distortion
and background hash. Did you know that there are many posts
on FIXYA about this same problem I.E. great TX , great PA but poor , or no audio out. these sets have been made in sevetal countries...The sets made in Taiwan or China have poor quality
front panel pots (the carbon track is micro thin and simply wares through to the material the track is printed on) This has the same effect as removing a wire from a pot I.E. no audio. The good news is that 99% of parts in the radio are freely available and that includes the front panel controls. ONE WONDERS IF THE SET IS WORTH THE EFFORT !!!
