Hi,the problem is from the output transistor or the oscillator,but most definitely the output transistor needs a replacement,however,if you are technically inclined,you should take apart your unit and replace the output transistor which is located on the pcb board.


Thanks and take care

Cobra 75 wx st everything seems to work eccept receiving signal meter will spike on trx and it seems to receive but no sound there is sound in wx mode


WX is for weather. If you put it on WX, and you do not hear anything, then you need to change the weather station it is on. in wx mode, you change weather channels by pressing channel up and down. To communicate with 2 way, press the cb/wx button so it is on CB mode.

Wx stations disappeared


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.

NO sound


Make sure the switch is in the CB position. If this is so, then you may have a bad switching transistor or a bad diode in the board. Also on some of the weather band cobras I have worked on in the past, I have found bad pll chips. Good Luck
