Thanks. Yeah if you could use the I2C bus, you can use newer tuner modules, premade. There's another researcher on the group that uses an FM scan chip, controled by 555 timer, so there's lots of possibilities. Mostly it's just a matter of providing the raw audio bits.

In this schematic, the mic amps and AGC are typicl of most of my boxes, and this shows where to by pass the agc to cut down the noise in the system. I took the AGC completely off the proto type board for this schematic.
