3.5mm jack output #38

Hey there,

I was wondering if it's possible to output the audio to the 3.5mm jack so I can connect it to my own transmitter?

No, it's not. But theoretically the program could be changed to do just that. But remember, your sound card needs capable of outputting at least 192kHz for RDS or 96kHz for stereo. Take a look at https://github.com/jontio/JMPX.

And you would need to make sure the transmitter doesn’t have a low-pass filter as this will filter out the RDS signals
