The most likely cause broken wire in mic a nice Roadking 56 would be a nice addition with better audio than factory mic.
The meter light is unrelated they burn out and can be replaced without replacing meter. Different colors and rainbow lights that chenge if you prefer. I find them annoying.
Good luck
Cobra Highgear mics are sold in Pilot truckstops that is a cheap replacement. There are the versions basic,noise cancelling and power mic. The power mics are for stock unmodified radios and will mostly squeal on a tweak radio from cb shop.
Durablity and quality audio tone for the price goes to the RK 56 mic they are about 70 bucks with tax at pilots.
Take the cover off, flip it over solder side up, check all solder joints for cracks, cold solder joints, check the safety diode where it comes in the radio, before I go further, can you pick up the weather channel?...Does the PA work?...need to check the pre-driver and finals,audio chip, hook up the power meter using a coax three foot jumper from the output from radio to the input of the watt meter, then the antenna, first check the SWR, on the scale on the meter to cal/swr mode,adjust it to spec, then while still keyed down turn the dial to SWR,if it is the safe range your ok,then turn the Dial to 10 or 20 watt scale and key the mic. Does it have any wattage? If not suspect the finals, they are located on the back rail, if it does have RF then its the audio chip, its located on the right side rail facing you,closest to you.remove it and replace it with same ....hope this helps....
Sounds like its not wired up right, the audio wire must be off,take the plug apart and check the white wire, re-solder it. here is the wiring, pin1-shield,pin-2audio-(white), pin3-transmit-(red), pin4-receive-(black).....hope this was helpful...
TX means transmit. There are 3 settings for the meter. The top one is to measure your TX/RX that's transmit and receive. CAL is to calibrate the meter to check your SWR.
Reasons your needle may not be moving much when you key while on TX/RX. The dynamic is probably all the way down. That is your mic gain. If you turn that up when you talk the needle will swing more. If the radio is stock and not modded, you can turn this all the way up and leave it.
Also there could be something wrong with the mic. If people can hear you then its not the mic.
If people can hear you fine when you transmit, it may just be a bad meter. Not a big problem, you will just need an external meter to make sure you swr is not high.this is important because if it is over 1.5 you run the risk of blowing the final transistor.
IF YOU CAN RECIEVE THAT IS A VERY GOOD SIGN THAT YOUR SWR MATCH IS OFF....I DONT KNOW IF YOU MATCHED UP YOUR RADIO WITH YOUR ANT.IF NOT YOU CAN BUY A CHEAP SWR METER @ RADIO SHACK...CHECK THAT YOUR COAX CABLE IS OK TRY TO REPLACE THE COAX......GOOD LUCK
cobra 4 pin is pin1= shield, pin2= mic audio (usually the shield is wrapped around the mic audio wire).pin 3= transmit or push to talk usually red or white whichever isnt wrapped with the shield, and pin4 = receive or speaker complete
5 pin cobra=1-Audio 2- Shield 3-Receive 4-Switching Wire 5-Transmit, you can jump pins 4 and two
Hello Darren, Yes it sounds like the mic is wired bass ackwards,,! A cobra 25 mic wiring is
PIN #1- Shield or ground wire
PIN#2- Audio or Transmit modulation
PIN #3- Transmit or Dead Key
PIN #4- Receive Audio.
When your keying the mic, the RX wires are being connected to make the RX work,,,
*** Let me know how you get along with it. Either buy a new mic wired for your radio or you or someone comfortable with soldering needs to resolder the correct wires back on the mic plug,,,Like I said, let me know and have a great day,, Mechanic is back quiet!
Hello birdhunter, no the cobra 200 has the same pinout as the 29's and such, but the color code might be different. Daiwa EM-500 Cobra CA Series 1- Shield & Black 2- Red 3- White 4- Blue STOCK Pinout Let me know how you get along with it,,,, Mechanic 1- Shield 2- Audio 3- Transmit 4- Receive
