Question about Radio Communications

Cannot get the cb's channel selector to go either up or down.

This is a cb radio that lives in my motorhome.I cannot get the cb's channel selector to go either up or down to bring in the various channels,it remains fixed on one channel.the knob turns ok. and I can hear a background hissing from the speaker and there's power to the unit,and oh yes it has worked fine in the past,the antenna is hooked up and I have not tried to make any adjustments on it to bring on this problem.
any help would be greatly appreciated.
Thank You
Arthur

check the SWR's if there high they will cause problems .. make sure your coax is 95%or better shielded type and have someone check the swr on the antenna should be free at any good radio shop..

Channel dial only works one way going down channels and will not go up any ideas how i can get this working please


that is an odd issue. each slot on the dial is a specific freq. meaning theyRAM h spot the non clicks I to is always going to be that channel. the channel selector sounds like it is bad. you can try contact cleaner on the selector knob. if that doesn't fix it you need to replace it.

My cb cobra 29 ltd problem is channel 1 is ok but channel 2 not receive


Did you have someone get on channel 2 to see??? Maybe channel 2 was quiet and channel one had better receive or noise.. You never know until you check it with another radio. That is NOT a common issue at all on those radios. Better off doing that test.

How do get my magnum cb on 19


Its very easy on this radio because it has a built in frequency counter. I can't remember off the top of my head but its most likely band letter A, then turn the channel selector to 19. If you are on the CB channel 19, the frequency counter will read 27.1850.

If band A channel 19 is not 27.1850 then leave the channel selector on 19 and flip through the band letters until it reads 27.1850. once you have found it, that letter is the CB band. channels 1 - 40 of the cb band.

Channel selector , part of digit burned out!like on ch. 19 it looks like 13!!


The LED channel displays on these radios are replaced as a unit. Look on eBay for replacements. They are usually available quite cheap and are rather straight forward to replace.
