 * (speedup) maybe replace high-order FIR downsampling filter with 2nd order butterworth followed by lower order FIR filter
 * figure out why we sometimes lose stereo lock
 * (feature) implement RDS decoding
-* (quality) consider type 1 PLL with ~ 10 Hz bandwidth for stereo pilot
 * (quality) consider FM demodulation with PLL instead of phase discriminator
 * (speedup) consider downsampling of IF signal before FM detection
