I have tried this. Although it worked it was not accurate at times. I'm kinda OCD when it comes to stuff halfway working so I ditched it.

Yes, the cellphone generates the audio to modulate the carrier with AFSK data. The cell phone will also decode the audio from the radio.
Which cable is better BTech aprs k1 or K2 cable for the Baofeng radio.
Which cable are you using K1 or K2?

You can use direwolf as well as a software TNC for PCs or RPis, I've been wanting to get this totally working with my Kenwood TR-2500 and a laptop PC but have been sidetracked trying to get a GPS working for the laptop... I got a few packets through to the APRS system successfully though it was a bit finicky with volume adjustments, of which a hardware accessory TNC would share similar issues.

The good thing about the Baofeng is that it supports VOX that the TR-2500 does not. That means I have to build some sort of computer controlled PTT on TX circuitry for the TR-2500, but VOX circuitry is a lot simpler than a whole hardware TNC at least...
