My uniden pc68ltw seems like it wont switch from weather band to cb. I can still hear the weather band after i switch to cb. I can not hear anyone one cb mode


You need to take off cover locate wires to that switch and cut them loose from CB/WB and buy a Toggle switch to mount outside radio and switch it on/off like to make CB/WB selection..Seems that switch inside is screwed. needs new one. I would rigg it myself. By drilling hole in cover and placing outside toggle with white marker saying Cb top Wb bottom.

I won't transmit or receive and it doen't key up. I hooked up a spare cobra 25 and it worked fine, but I like Uniden better.


Hi,my name is John. Welcome to FixYa. First try a different mic, one thats wired for it, if I remember the cobra mic will work on it. If that does not do it, let me know, might be internal that I also can help you with. Good luck and thanks for choosing FixYa....John

I have a uniden pc68ltw cb radio and it keeps blowing the 2amp in line fuse i tried a 5amp but still blows the fuse.i hooked it into another truck to test it but still blew the fuse. something wrong with...


Hello,

have you been using the uniden pc68ltw cb radio without the fuse blowing before?

If the uniden pc68ltw cb radio has not been blowing fuse before, then might be a problem from the radio. This problem should be a power related problem.

The fuse blowing means there is excess of current. So while your trying to refuse, thicken the wire.

Best regards.

I can only get the weather channel but the cb side dosen't work what do you think it can be?


You don't give me much to work with. Is the weather selector switch in the CB position? Do you have an antenna hooked up? Have you checked the SWR on the antenna? What power reading do you get when you key the mike?

Please give me some feed back.

I have sound but no tsmt,the tsmt light does comes on,no output


well that leaves 2 mor parts the transmit final and the current resistor these have straight 12 volts applied when the radio is turned on . if you look at the final it will be burnt or blown apart on the heat sink. replace them and you shoul be up and talking again.

I can't pick up anything...


Hello even though everything is connected properly, have you checked for standing waves on the antenna to radio connection? Also you may have to perform a sensitivity test on the unit. The problem is you need a RF generator for that. Set you RF generator to the frequency that is equal to the CBs middle frequency and modulate the CW with 1KHz at 50% modulation, tune to the middle of the CB band on the radio and set the output of the RF generator to .1uv and loosely couple the signal to the CB antenna with a loop of wire. Your CB should be picking up a 1KHz tone gradually turn the power level down and when the tone cuts off that level is cutoff level, then increase the level until you can hear the tone again when the tone cuts on that value is the sensitivity of the unit. Compare the measured value to the value in the owners documentation. if the sensitivity is low this could denot a problem in the RF/IF section of the CB.
