As for sound issues, I can say from our experiences on the Pride of the East podcast that we can all sound perfectly fine to eachother, Nathan can do a short recording test which sounds fine when played back and everything can be as clear as a bell.....until you play the full episode back after editing and it sounds horrendous. As you say any broadcast sinks or swims on its sound quality but sometimes the amateur stuff that folk do for the love of it (like us) can for no apparent reason be off.
