Good luck and kind regards.

When docking the headset cobra road trip and activate the ptt who hear me get a ring


  • Hi, I can help. When the microphone/earphone set is inserted in the radio itself the control is automatically turned over to the headset. There are no radio adjustment that need to be done. Just plug it in and use the PTT on the cord of the headset or unplug and use the controls on the radio itself.

  • Many don't know that the Cobra Road Trip and the Cobra HH 38WXST are identical radios. The only difference is the antenna sold with the two radios. The one you have come with a rubber duck style antenna and the HH38 WXST comes with a magnetic car mount antenna. So while the manualfor the Road Trip is hard to find the 38 WXST is not. Here is a copy of the manual http://minus.com/mTQOgU0yw

  • Read through the manual a couple times and feel free to get back to me with any questions you have.

  • Hope this helps.

Customer has lost his power supply cord. where can he purchase another cord. power cord is three prongs.


  • Hi, I can help.

  • For the Radio Shack TRC-447 this is just a standard 3 PIN DC cord. Many CB's use the same cord and they are interchangeable. Some Cobra, Uniden, Radio Shack use the same cord. Texxcomm is a great place to get parts from.

Does not seem to have very limited range


Hi, my name is John. Welcome to FixYa. All of the handheld,s have very short range. Try to extend the antenna as far as it will go and depending on your location, it should get out a little further..good luck. Thanks for choosing FixYa... John

Cobra 75 wx st fuse keeps blowing. As soon as I plug the transceiver into the connector box the fuse blows.


Hi and welcome to FixYa,

Initially, check the reverse protection diode, D18 (1N4004). It would be located / connected at the power board of the DC connector.

Good luck and thank you for asking FixYa.

I just picked up a Cobra 18 ultra CB Rig at a Farmers Market, and would like to know how to install it in my 2007 GMC Denali?


all you need to do is find a continuous live 12v feed, usually the cigar lighter, join the red wire from the cb, to this feed, and the black wire from the cb is the earth, and fit a mag-mount cb arial

My Cobra Road Trip handheld CB won't switch over to battery power when I unplug the 12v adapter. How do I open the casing to check if the spring behind the connector can be repaired or replaced?


Make sure you have good batteries in it ,and installed correct. There should be a switch behind the battery,i think.... but there is a switch on it for ac or dc,switch it to dc,make sure you have the ac plug adapter end unpluged from it in order for it to work......hope this helps.....
