WARNING:

On radios with more than four pins you may often find that there is a voltage present on one or more of the
other pins. If you short this pin to earth or to another pin you may damage the set.
Do not use the method below for checking the radio wiring if this is the case. With the radio switched off,
use a multi meter to find which pin is earthed. This will be the COMMON.
Switch the radio on. Turn the volume to half way and open the squelch.
Connect a short wire to the –ve of your power supply. Touch the other end of this wire to each of
the pins of the microphone socket in turn. One pin will cause the radio to start receiving (noise heard from speaker).
This is the RECEIVE pin.
One pin will cause the radio to start transmitting (light illuminates or meter keys across).
This will be the TRANSMIT pin.
The final pin will be the AUDIO.
If there is more then one unidentified pin the Audio pin might be identified by keying the radio and then touching
each pin in turn with your finger. When you touch the AUDIO pin a buzz can be heard on another radio or receiver.
Below are diagrams showing radio wirings for several radios. The diagrams with thin black outline and black pins
are for DIN plugs. The solid black diagrams with white pins are for normal ‘screw-in’ microphone plugs.
For all ‘screw-in’ microphone plugs the pins are numbered anti-clockwise from the top left hand pin (from the
solder side). If you need further assistance just contact
Oscar Kilo. Head quarters UK. Andy 26 OK 001.

How to wire a Microphone

If you are lucky, both your radio and microphone details will be listed. You should then proceed with the following steps..

                  1. Look up the wiring diagram for your radio.. On a piece of paper draw the
                       Microphone plug as shown in the appropriate diagram. These diagrams
                       Show the plug from the side you will be soldering.

                 2. Look up your microphone and find the colour code. Transfer the colours
                     listed to your drawing, substituting the colour of the wire for the function
                      Listed on your diagram.

3. Now simply solder the wires to your plug exactly as you have them shown In your diagram
Astatic mic wiring for Audio line Radio.

FOR EXAMPLE
On radios with more then four pins you may often find that there is a voltage present on
one or more of the other pins, if you short this pin to earth or to another pin you may damage the set
Do not use the method below for checking the radio wiring if this is the case.
With the radio switched off, use a multimeter to find which pin is earthed.
This will be the COMMON.
Switch the radio on. Turn the volume to half way and open the squelch. Connect a short wire to the -ve
of your power supply. Touch the other end of this wire to each of the pins in turn.One pin will cause the
radio to start receiving… This is the RECEIVE pin.
One pin will cause the radio to start transmitting. This is the TRANSMIT pin. The final pin will be the AUDIO

If there is more than one unidentified pin the AUDIO pin might be identified by keying the radio (by earthing
the transmit pin) and then touching each pin in turn with your finger. When you touch the AUDIO pin a buzz
can be heard on another radio or receiver.

There are basically three kinds of microphone used on CB radios
                            1 Dynamic standard microphone
                            2 electret (Condenser) standard microphone
                            3 power (amplified) microphone

Dynamic is the most common.. The electret microphone is more common on newer radios because of its compact
size & sensitivity. This will require a small voltage across the element. Not suitable for radios designed with dynamic mics

The power mic is basically either a dynamic or, more usually an electret mic with small amplifier built in the mic
handset with adjustable power slide .

Many new radios are manufactured with channel changer. up/down controls on the microphone, which work in
addition to the channel change on the radio .if I have missed any thing or you require any further info not on the
okdx websites please let me know.

we hope we hope to catch you on air best 73,s from all the Oscar kilo magic team
