It's only for radio operators that want maximum range from their rig.

Along with maximum splatter.

In looking closely at his photos, it appears his circuit is based on the
Analog Devices SSM2166 (product data:http://tinyurl.com/6eadpn). *The

Based on the photos I've seen, I wouldn't buy one because of the poor
soldering:http://img105.imagevenue.com/img.php..._122_173lo.jpg.
I'll just continue to use my 2-tube (2x 3-500Z) speech "processor":http://www.rigpix.com/linears/sb220.htm

WA7PRC, you are absolutely correct that the design is based on the
Analog Devices SSM2166 chip. I'm curious about your soldering comment.
Why do you feel the soldering is poor? We have not had a single
failure due to poor soldering. We have approximately 400 units in the
field at this time. The field failure is around 0.2% during the one
year period that these units have been on the market.
