Advice needed with Clansman headset connections

[Hartas]

I’ve read the thread about adapting a Clansman headset to use with a CB. The CB is a Kenwood TRA700 with a 4 pin plug but the pinouts I’ve found use different terminology from what is used in the thread and I just want to check with someone who knows about these things (which I don’t!).

 

The 4 pins on the Kenwood are:

1 Mic Hi

2 PTT input

3 Ground for PTT

4 Mic Lo (ground)

 

I think this translates to:

Clansman Pin D + G wired together to Kenwood Pin 4

Clansman Pin A to Kenwood Pin 1

Clansman Pin F to Kenwood Pin 2

Clansman Pin E to Kenwood Pin 3

 

Is this correct?

 

I’d be most grateful for your advice and any corrections.

 

Thanks

The obvious issue here is that the Kenwood connector is only for a microphone and doesn't have anything to connect the Clansman headphones.

Hi

 

The clansman connections are:

 

Note that this is the fixed socket on the radio - the free cable is mirror imaged looking into it.

 

The Clansman ground (E) and the headphones (D & G) need to be taken by a separate lead to the external headphone or speaker socket on the radio, if there is one (or you can fit one).

 

The 4 pins you have identified can be wired thus

 

1 Mic Hi = Clansman A

2 PTT input = Clansman F

3 Ground for PTT = Clansman E

4 Mic Lo (ground) = Clansman B

 

Note that the headphones D and G are independent and can be used for different radios (e.g. CB in left and FM Broadcast in right)

Thanks Andy and Iain,

The Kenwood does have an Ext. Speaker jack plug which is where it would seem that I need to connect to Clansman pins E, D+G.

I'll follow your suggestions for wiring the 4 pin Kenwood connector. Many thanks for your help.

Cheers

That should work. Just be careful with the volume in case you deafen yourself!
