I've got a cheopo BaoFeng UV-5RE that i'd like to try as packet radio. I've snipped the plugg off of the headset that came with it, soldered it onto some breadboard cables, and did the same to one 3.5mm jack plug connector intended to go in the soundcard. *(i'd prioritize getting listening to work, first)* But, having done that. The after-tought hit me that the speaker-out on the BaoFeng is mono, while the port(s) on the soundcard is intended for stereo.. **Would anyone be able to help me out with a wiring plan?** Feel free to doodle on the image for rough illustration. (sorry for the hasty image) [![BaoFeng to soundcard line-in/out wiring][1]][1] Push-To-Talk is not very important per se, since the radio have 'VOX' function, but if that's not recommended maybe i could use an arduio that i bought for the task at hand as (linux) serial-PTT ? ..And perhaps also as a go-between the radio and the pc?
