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

switching diode

d-23 is a 1n4004 diode . replace it and see if that works. It should>

there is a capacitor ,I think its c801 that you have to cut .cb should be restored.unless you want wx.

Here is the list just scratching the surface.

• Bad antenna
• Bad coax cable ......grounding externally or internally with shield.
• Bad/poor ground for antenna..........door to body, painted parts when mounted elsewhere.
• Antenna installed incorrectly. Nylon grommet must insulate antenna from contact with mounting bracket. Coaxial connector must have contact with bracket for grounding.

Press the lockout button...there should be a switch in the back of it ...flip it...now try.....hope this helps...

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.

This should be just like a cobra 25. I don't know who told you it wasn't.

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.

It would be fairly expensive & therefore impractical to do.

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.
