I'm wanting to get into the world of IEM and a relatively silent stage...but I don't gig frequently enough to justify a professional-grade IEM system. I'm considering a couple of the cheaper IEM solutions (Galaxy Audio, VocoPro, etc)...but it also occurs to me that I might be able to get away with using a decent whole-house FM transmitter and pocket radio. However, I can't seem to find any information about anyone doing this in a live band context. I'm just wondering if it's a feasible solution, or are there are glaring issues that would prevent it from working? (Aside from the obvious risk of radio interference and having to find a clean frequency for every gig).
