SOURCE: cb problem have a cobra 19dx iv with a 2ft magnet

Hi and welcome to FixYa,

Which output is muffled, transmit (modulation audio) or receive audio?

If you are referring to the receive audio, initially, have you tried an external speaker? If it works good, then it would be an internal speaker problem; if not then others to check would be:

  • IC1 - KIA7217AP audio IC;
  • CM 10 & 15 - audio output capacitors 470uF / 16V.
if it were transmit / modulation audio, try replacing the mic.

Please postback updates.

Good luck and thank you for asking FixYa.

check the swr's on the antenna. all shops should do it for free just to check them. WE DO here in texas.. but if antenna isn't install properly then it may be high swr causing short distance.

Just buy a factory built antenna/(it should be close) Buy you a magnet mount RADIO SHACK job(works). If your indoors buy ANTRON A99(set at 1.3 SWR factory). If it keys 9 db then that equals 4 watts output thats OK.

Ok so when I bought my '97 jeep wrangler a couple of months ago it came with a CB. It is all hooked up, came with a huge antenna( 4-5ft maybe), all of the lights come on, the weatherman channel works, and...


check the sw's and the antenna. those are SHORT antennas by cb standards. a 1/4 wave is about 9ft long. a full wave is around 36 ft.. so anything shorter than the 102" whips are prone to have less range. if swr check out. the board on the 18's and 19dx styles need to be resoldered from time to time. simple fix .. don't pay more than $8 to fix the radio...

Why does my cobra 148 GTL CB give out a squeeking noise when i trasmit as heard by others receiving me ??


is this a new radio? if so then the voltage change on the vco/pll will cause a squeak. kindda like a cobra 19dx does. also like the old golden eagle squeal .. all due to the voltage being unstable.. now is it that prob or do you have talkback and its loud/bad grounds causing a squeal. that could be the case too. if you have talk back let me know there's a cure for that. contact us..we can put the talkback just lil outtaphase to stop 99% of the squeals in cobra/uniden chassis radios.
