I went out and bought a stereo cable today similar to the one that I linked to above. It didn't work either, however, I was able to get it to work by only plugging the cable halfway in to the jack on the back of the MRF-350. I'm happy that it's working, but I'd prefer to have a more solid connection that won't accidentally fall out. I don't know much about this kind of stuff, so I'm not sure what exactly is going on with the signal and why it works when I only plug it in halfway. Is there some kind of adapter I can buy? Would something like this would work?
