Hi and welcome to FixYa,

Initially, pls a couple of ideas you may want to consider/explore or try/check:

  • PA/CB switch must be to CB;
  • RF Gain max clockwise;
  • Squelch counter clockwise;
  • Volume to your desired level;
  • Mute (off);
  • external speaker/speaker connection;
  • audio amp, verify if there is TX modulation;
  • antenna, antenna cable. SWR should be low.
Good luck and Thank you for using FixYa. Happy New Year.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate this at all. Cheers.

Its, either a broken wire in the mic or the internal speaker blew. Try an external speaker then the mic

They did not put all the plugs back in from the weather board. Part of what has to be fiddled with is underneath the weather board.

Open the bottom cover where the speaker is, on the right side you will see a board separate from the main board. Look for any plugs unplugged. Its probably one that got over looked.

If there are no plugs out, who ever you took it too may have turned something they should not have. most likely its a plug. Its probably the plug that runs the audio into the radio from the weather board. its working, the audio just isn't getting to the rest of the radio.

there are about 3 or 4 plugs from the weather board to the main board of the radio.

My cobra 18 wx st comes on and goes tru all channels but has no noise at all coming thru it. none of the signal strength lights come on or anything. its brand new.


Sounds like a antenna issue. Make sure coax is in good order.and antenna is connected properly. You might have to get a "swr" meter to put in line between radio and antenna to make sure antenna is "tuned" to were the radio is operating. Radio shack sells a ok low budget swr/power meter.

Can i peak and tune a cobra 18wx st


technically , yes legally , no. besides this is a false statement. A radio is already tuned when you get it by the factory. now the true part is the it should be tuned to specs otherwise you are possiably interferring with other operators on the amature bands 4 watts is max and 95% mod will give you plenty of swing.

Where can i get tuneup specs for Cobra 18 wx st extra low modulation


The cobra 18 wx st is the worst radio Cobra ever made. I don't know why they still make it. It's not gonna do much no matter how much you tune it up. Its a bad radio.

Get a cobra 29, and turn VR4 all the way counter clockwise.
(this will not work on the 18)

VR2 is modulation in the 18 wx st. adjust it while checking on a watt meter to see when its all the way up.

I have a cobra29 wx nw st. its been peaked and tuned, an echo board installed, and soundtracker override when i key up if my mic gain is over 1/4 the way up it makes an awful racket what do i do?


is there talk back installed? if so its probably too loud. You are getting feed back. The talk back should be low, just enough to hear it to check echo. 470 ohm resistor is perfect.

Cobra 18 wx st for mobile use, ned to switch reg mic for cherokee power mic. need mic diagram for the four pin


You probably don't want to hear this, but the cobra 18 wx st is just about the worst, and most hated radio ever made. Its a very poor radio.

to be very honest with you, you should get rid of that radio, or return it. Then buy a cobra 29 instead,

for proper mic wiring, please reference this page.
