What do digital radio modes sound like?
With the growing popularity of digital radio data monitoring using SDRs, the question arises “exactly what digital data protocol is being received?” It’s easy to tell the digital data from analog transmissions like SSB, FM, AM and CW, but sometimes it’s difficult to even discern radio data transmissions from RF noise. And when you recognize a digital transmission, which mode is it?
Gary Hahn, Amateur Radio Licensee KB9UKD, has amassed a comprehensive collection of audio clips of various digital modes on his Digital Modes Samples website. PSK31 is an easy one to detect aurally, but can you pick out JT65A? APCO P25? MFSK? After checking Gary’s site you’ll have a better idea of what modes you’re hearing, and be able to know what demodulation software to use. Also see his links to mystery modes and to sites with additional amateur radio mode sound files.

Good post. I learn something totally new and challenging on blogs I stumbleupon everyday. It’s always helpful to read through articles from other writers and use a little something from other web sites.
