I have a Baofeng UV-82HP that I want to use to TX and RX to a TeamSpeak Server. For this I'm going to use a dedicated computer, for both the client and server that has a sound card (ASUS Xonar Essence STX) that is not used by the OS or any other applications (so, there will be no spurious transmissions.)
I want to take the computer audio, and put that through the radio's accessory Microphone Port. That's a simple 3.5mm TRRS from the Radio's MIC port into the Line-In of the Sound Card.
I want to take the audio from the radio via the radio's accessory Speaker Port, and put that into the microphone for the sound card. From the Speaker Port I'm using a 2.5mm TRRS to 3.5mm TRRS adapter, then 3.5mm TRRS to the Line-In for the Sound Card.
The problem is when I complete the connection from the radio's accessory Speaker Port to the Sound Card's Line-In, it causes the radio to transmit. This happens even with the radios's accessory Microphone Port unplugged. It does not happen when the 2.5mm TRRS to 3.5mm TRRS adapter by it's self on the Speaker Port.
The 2 Pin Kenwood uses a TRS style for both Speaker and Mic, should I use a TS for the Speaker to bypass the PTT functionality of the circuit?
