Codec2 Project Asks FCC To Modernize Regulations 89
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."

Blah blah blah I'm Bruce Perens and I'm so wonderful. I get such a kick out of submitting my own worthless shit to the front page.
The AC got modded down to oblivion for this comment, and given how it was written and how fast some mods pull the trigger, I'm not surprised.
However, you've got to admit that a Slashdot submission that reads "xxx writes: a 24-page FCC created by xxx proposes that..." make xxx appear insufferably conceited and self-obsessed, be xxx Bruce Perens or anybody else.

It is a fertile ground for experimentation! You need look no farther than the recent influx of extremely spectrum-efficient modes developed by K1JT [princeton.edu]. He's developed modes tailored for most any propagation mode/band including meteor scatter, moonbounce, etc.
The newest of the lot, the JT9 modes, are capable of decoding signals as far as 42dB into the noise! [princeton.edu]. The fastest JT9 mode takes 1 minute per transmission but can decode at a S/N of -27dB - that's noise with 500x the power of the signal.
Take a look at the WSPR page [wsprnet.org] - on it you can access a database of WSPR transmissions [wsprnet.org], some of them at amazingly high km/Watt ratios.
