My project

[jfast]

Hello everyone,

I would like to transmit my audio from my phone to my car through fm using TP/TA flag.
So I would like to use this system: http://pira.cz/rds/rdsmp3tx.pdf
but the customisation I need is simple:
If there is some sound from audio source, then add the TA flag.
No sound, no TA flag.

So when my phone give some sound, It will be play on my car...

Can you help me making that ?


PS: sorry for my bad english

You can realize it if electronics is your hobby. However keep on mind that TA flag cannot force the car radio to tune from another station to your phone transmission. Thus I think the final result will be poor compared to effort required.
