A colleague recently asked if it is possible to build a simple shortwave receiver from an old cellphone or parts of multiple cellphones. Most of us have heard of FM chips in today's phones but I'm at a loss. Anyone ever try this before? My spouse is ready to upgrade her iPhone 5C so that might be my first opportunity to break a phone apart and see what happens. 73s. AJ (KK4UYV)

I'd say that if the manufacturer used IC die and connected them to the real world with 0.001 inch thick wires with wirebonding machines, then covered them with epoxy for protection, those semiconductors are unusable by the average ham.
