    Bruce Perens writes "Codec2 is the Open Source ultra-low-bandwidth speech codec capable of encoding voice in 1200 Baud. FreeDV (freedv .org) is an HF (global-range radio) implementation that uses half the bandwidth of SSB, and without the noise. Here are three speeches about where it's going."

    Bruce Perens writes "The Codec2 project has developed FreeDV, a program to encode digital voice on two-way radio in only 1.125 KHz of bandwidth. But FCC regulations aren't up-to-speed with the challenges of software-defined radio and Open Source. A 24 page FCC filing created by Bruce Perens proposes that FCC allow all digital modulations and published digital codes on ham radio and switch to bandwidth-based regulation."
