Very cool concept! Radio stations used to share software over the airwaves by using something like this.

How long would it take to transmit a 3MB jpeg and then encode it,?

Thanks!

Using an audio cable (for better SNR), I have managed to achieve and sustain 60kbps for long periods time - so 3MB file should take ~7 minutes to transmit.
