Microphone Connections
Welcome, this page discribes microphone wiring connections for most UK and foreign radios. Most U.S. radios are “Code Type 2”, so if the radio you want to wire a mic up for is not mentioned here, be sure to try out “Code Type 2”. If you know of any other radio / microphone wire schemes that are not mentioned here, please send me a E-Mail to the address at the bottom of the screen.
To Use this Chart: Look up your radio. To the left is a “Type” number. Look further down the Chart to CODE section. Find your number. This is your radio’s mic wiring. Further down the Chart are a few microphone’s and their wiring pinouts. Remember that the Shield wire is most alway’s wrapped around the Audio wire.

Tnx for the valuable microphone wiring references ……I found the information I needed this time and a valuable resource for future research with the ” screwdriver and solder – weapon”…..I am much obliged!!!
what a great idea to publish this on your website ,,,great,tnx

Thank you for publishing this most comprehensive list.
Jim aka Long Distance Operator – Searcy, Ar
The Turner 3 wire if used on a 2510 would you connect the red and shield together as there is no recieve connection on the 2510.
i have a Trinidad 2 base 23 channel and im trying to wire a cobra hand held mic to it.. Any one have a diagram for this novice to work with..

It does not transmit.. any help would be greatly appreciated.. email me at gary_dube36@yahoo.com.. Thanx Gary
Can anyone please give me the wiring code for the echo sadelta master plus to go into the icom706 mk2 your help is much appreciated. My email address mu876@hotmail.co.uk please let me know via email thanks you
Hi, What wiring information do you have that shows how and connections for a Astatic D-104 G and other D-104 amplified. ?

Thanks for excellent informations you provide us Simone. 73
HELLO SIR. MY NAME IS JIM…IS WHAT I WANT TO DO IS WIRE A D-104 T-UG8-4 WIRE TO A COBRA 2000GTL-5 PIN…MY QUESTION IS HOW DO I DO THIS..WHEN THE RADIO HAS A 5-PIN PLUG AND THE D-104 ONLY HAS 4 WIRES…CAN U HELP ME….
What effect will a Turner Plus 3 transistorized microphone with a 5000 ohm impedance connected to a Yeasu FT-847 which usually has a dynamic microphone with a 190 ohm impedance have on the quality of the sound produced ?
Looking for the wiring to use the sadelta echo master plus on my Kenwood ts430-s
I have a Uniace 300 and I wish to wire my Astatic Silver Eagle, I can get it to tx but not to rx . Your help would be appreciated.
