sounds like you popped the audio amp. hold the radio with the dials towards you and check out the right side of the unit.Put your nose to work and sniff around that area to smell anything that might be burnt.

I have a cobra ltd 29 bt hooking to a 102 inch whip and cannot get m swr readings down under 3 or it will go up higher then the calibrate triangle instead of down. my antenna is mounted with a gumdrop...


  • Sounds to me like you need to check the connectors and connections on that coax. A cobra29 and a 102" whip is a simple enough set up and should not produce that high of SWR unless the coax or the connectors on the coax are pretty messed up. Also i recommend putting an SWR meter in line.
  • The meters on them Cobras can be accurate sometimes but I trust an inline meter much more.
  • Ground it again to make sure.

Cobra 29 has bad connection


Sounds like the audio out put transistor is over heating. Could be from having it tuned to high. It will need to be changed.

My superstar 3900 transmits on one channel and receives on one ch


Ok! well i deffinitally know what the problem is. You need to play with the clarifier, i think all the way to the left is a "course and fine tune" knob. This is generally for use when talking on SSB. but may affect AM if its way off.

The clarifier lets you slide on the freq. some radios will go a full channel some will only go a little or above the center of the channel. You need to play with the clarifier, you probably need to turn the course a lot, untill the audio is almost clear on the channel you want to talk on, than use the fine to tune it in so it sounds like they are sitting right next to you.

what you should do is buy a Frequency counter, you got a nice radio, so the freq. counter wouldent hurt. lets say you want to be on channel 19. you would turn the clarifiers untill i read 27.1850 That would put you right on the money

No sound


Yes It sounds as though the audio amp may have taken the hit go to this link and download the service manual it will give you voltage info http://www.cbtricks.com/radios/cobra/25ltd_st_25wx_st/index.htm ...Chia
P.S. If you have an external speaker plug it in to the PA hole on the back put the radio on PA and see if you get any sound then if the dynamike is turned up it will be LOUD.If not I would replace the audio amp.If you need one let me know and ill directc you in the right direction...Chia

Cobra 148 gtl Low / No receive audio


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 !!!

CHEERS GUYS / GIRLS.
