Radio World this month profiles the recipients of our 2010 "Cool Stuff" Award.

Why are only half of the folks in the photo holding up their hands? Because the group is asymmetrical!

Asymmetrical Sideband Technology comprises a suite of proprietary algorithms that permit broadcasters to address adjacent-channel interference by accommodating the full –10 dBc HD Radio signal on one sideband while keeping the other sideband at more conservative –14 dBc injection levels.

"Asymmetrical Sideband technology (subject to FCC approval) is a capability of Nautel's HD PowerBoost suite of technologies that can provide a marked increase in power output (up to 30 percent improvement) and up to 7 percent gains in transmitter efficiency in HD Hybrid transmission modes," the company says, and the "Cool Stuff" judges were impressed.
