That's what I use, it's quite robust, very high dynamic range and overload point, but they don't put the schematic for their stuff in the user manuals, which is a huge black mark in my book. Makes it a PITA to troubleshoot when you have a problem -- you've got to trace everything out. 73, Jim K9YC _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
