Port audio VHF COBRA PORTABLE HH330

[aries83]

Hello,

I have a VHF cobra HH330 and I am looking to connect an audio cable to the microphone/speaker input.

A 3.5 mm jack cable does not work, the same for a 2.5 mm. It seems that it's 2 mm but I can't find this reference online. Can you tell me which audio connecter I need to buy to be able to plug something into it? The documentation mentions a Jack port but obviously it's not good.

I think that’s the connector we can see here but I don’t know the name…
