rates of 6 to 16 bits per second. heh... my cellular "power" amplifier is maybe a little faster. But then, this one won't lose a wrestling match against an electric toothbrush... _____________________________ Posted through www.DSPRelated.com

Ha, unfortunately I can't tell you the sorts of things our PA have had to wrestle against ... !!! They use about low hundreds of watts depending on the exact setting, and we have the distance record of around 13km. The record is being broken all the time with the many horizontal ultra-long distance wells being drilled. Here's one from a few years ago that a had nice number: 12,345m. https://www.slb.com/news/press_releases/2011/2011_0421_q1_earnings.aspx http://news.exxonmobil.com/press-release/sakhalin-1-project-drills-worlds-longest-extended-reach-well
