I wouldn't bother with the excersise at ALL. I'd be using an Ipod, too.
using a phone w/ a soft66 SDR stowed in a leather case originally designed for SONY microcassette, for 0-75 MHz, and a rtlsdr dongle for 75 to ~2ghz. combined cost sans phone less than iPod nano. the technology is there, but unless you ask a question like "how can i hear WBZ with a brickwall FFT right before the IBOC sideband ..while on a Red Line train..in a tunnel.. with full quieting", you probably wont go down the portaSDR/coil route. nothing wrong with appliance-operating anyway
still waiting on some ARM binaries from the iBiquity consortium so i can get WBCN-HD. pretty please?
