Hello,

I'm a FPV newbie and I started building a simplitic telemetry using the unsed audio channel in my FPV setup:

1. On the plane there's an arduino with arduIMU which encodes the data in FSK.

2. On the ground I'm using a laptop with screen grabber. The audio channel goes to my sound card where it can be processed.

While it's easy to encode a FSK signal, the decoding is not so obvious. Ideally, I'd like to use a 3rd party software which reads the sound card input and e.g. sends the decoded data through a network connection. Do you know any software that does that?

Alternatively, I could use some C/C++ decoding library. I found some code for decoding bell-202 in an opensource router but it's hard to extract for mine own use without deep understanding how it works). And if everything else fails: do you know a _good_ source where I could learn about decoding FSK in practice, without using additional hardware?

I'll be really thankful for any help. I did my homework and spend a good amount of time googling but couldn't find anything that would be useful for me.

cheers!
