How to wire sadelta echo master plus classic red white brown green braid wires to four pin cobra 148gtl dx

I believe to wire a Sadelta M3 microphone to a Cobra 29 LTD Classic CB radio:

The Sadelta M3 microphone has four wires: white, shield (bare wire), red, and black. The Cobra 29 LTD Classic CB radio's microphone jack also has four pins: Pin 1 (Audio), Pin 2 (Ground), Pin 3 (Transmit), and Pin 4 (Receive).

To wire the Sadelta M3 to the Cobra 29 LTD Classic, you need to connect each wire from the microphone to its corresponding pin on the microphone jack. The white wire carries the audio signal from the microphone's element to the radio, the shield wire provides a ground connection, the red wire activates the radio's transmit function when the microphone is keyed, and the black wire is used for receive audio.
Here are the specific steps to follow:

1. Cut off the existing microphone plug on the Sadelta M3 microphone cord.
2. Strip about 1/4 inch of insulation from each of the four wires in the Sadelta M3 microphone cord.
3. Connect the wires to the pins on the microphone jack as follows:

• White wire to Pin 1 (Audio)
• Shield (bare wire) to Pin 2 (Ground)
• Red wire to Pin 3 (Transmit)
• Black wire to Pin 4 (Receive)

1. Solder each wire to its corresponding pin on the microphone jack. You may want to use a multimeter to verify that each connection is solid and that there are no shorts or open circuits.
2. Once you have soldered all the wires, test the microphone by speaking into it and checking that the radio's TX meter moves as you speak. Also, check that you can hear audio through the radio's speaker when receiving signals.
3. If the microphone is working correctly, use heat shrink tubing or electrical tape to cover the soldered connections and provide strain relief for the wires.

Note that some microphones, including the Sadelta M3, may have additional features such as a built-in amplifier or power supply that require additional wiring.

ALTAI PWR MIC - black/braid= earth, red=RX, white=TX, Yellow=MODASTATIC - blue/braid=earth, black=RX, red=TX, white=MOD, Yellow=Spare
SIRTEL ECHO MIC CBE 2002 - black/braid=earth, blue=TX, white=RX, red=MOD007 POWER MIC - brown/braid=earth, green=RX, white=TX, blue=MODSADELTA EC 980 - braid=earth, green=RX, brn=TX, white=MOD
or braid=earth, black=RX, blue=TX, white=MOD

depends on what parts you need but this company sells a few parts for sadeltas but limited !!! www.hyelectronics.com good luck !!!!

Hope this helps

Here are the Pin outs for different mics that will work with your radio. If a wire is not listed then you cut it off. It's best to keep the wires as short as possible no longer than a half inch is suggested. Normally the Cobra pin out is standard for most radios.

Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.

ALLways start with ground. Find ground on radio pin with ohm meter. EVERY thing operates off ground. Once you find ground on radio....solder your ground wire on mike cord to corresponding # on mike jack. Once you have ground on proper pin then all else is elementary......use ohm meter to see which wires are TX and RX on mike.....last wire is audio wire.
