Hi there,

I have the MTM5400 (MR15.1 firmware) and I want to connect it to the SVXLink via soundcard.

According to the installation manual, the pin 14 of rear accessory socket is RX_AUDIO line output.
I've tried to connect this pin to soundcard's line input, but got no signal. I've successfully got RX audio signal from pin 10, but it's external speaker pin, and audio level on this pin is not good.

Can anyone help me with this? I think that there are some options in codeplug regarding to audio line out configuration.

Thank you.

speaker connection intended for low impedance load - like 8 ohm speaker, whats why you got low signal. maybe you didnt have audio from pin 14 because you didnt connect ground (pin 8) between radio and PC soundcard?

I'm hazarding a bit of a guess here, but in the radio settings: Menu/More/Setup/Accry Type - is it set to external?
