TUG 8, TUG 9, TUP 8 or TUP 9? What radio? If it's a pre-amplified or power mic, there is a screwdriver adjustment under the base and a 9 volt battery in the base. The battery could be dead or the mic is turned down. If it is not a preamplified D 104, it wont be loud unless you run it on a Tram or Browning Tube Radio that accepts a high impedance mic. I hope this helps. :-)

I have a none amplified D104 G stand it came off my TRAM D201 IT has a two center leeds that's shielded I know this will work on my cobra 29LTD but I don't get it please help


First, you have to replace the cable as you will need a minimum of 4 wires, 2 of them for the transmit and receive switching, and a shielded cable for the audio. It would be nice to have another as the common for the TX/RX switching but the shield is commonly used for this.

You will need to re-wire the switch in the candlestick to allow switching from RX to TX.

Google "D104 to cobra 29 mic wiring" and you will find many hits for this.
Your microphone was not intended to work with this style of radio. To save a buck, the CB manufacturers removed a 50 cent relay to do the transmit/receive switching. You can see what happens when you remove the microphone when you are listening to the Cobra. It'll stop producing any sound. This won't happen with the Tram,

Also, you may have problems with the microphone as it is high impedance as indicated by no transformer or preamp in the base of the microphone. This may be a problem as the Cobra has a relatively low impedance input.

When i keyup my d104 mic on cober 148 gtl ihear feedback squeal.but the d104 work good cobera 2000 gtl


try to keep the mic away from the radio speaker.check to see if its turned up to high.check your mic gain to make sure its like 1/2 open.If these fail then you could solder two 0.001 ceramic disc capacitors from the audio to the shield wires about 3" apart.then on the audio wire in between the 2 caps solder a 4700 ohm 1/4 w resistor.this should work.

How do you retrofit a 4 pin D104 to a 2 pin model?


A two pin does not use a Push To Talk circuit so one wire you want is the Audio wire and the other is the ground wire.

Im trying to wire a astatic d104 m6b to a galaxy 949 mobile can you give a color code for what color wire goes were?i have black white red blue and a bare wire thank you.


This works for any mic.
dont worry about color codes. look at the switches.. there will be a common on both poles of the d104.. those need to be tied together to grnd. pin 1 on mic . the others d104 on n/c side is your rx. pin 4... the n/o one will be your tx pin 3 the other n/o will be audio and will have a wire from the mic element also on that pole of the switch. pin 2..
