I am more of a software guy. Prior to resampling I already used a low-pass filter to get the section of signal I need. The GRC file I am basing my program off of simply has "[]" for the taps, so I am assuming a neutral element is needed.

Thanks! Clearly I have a lot to learn about RF. -Luke -- _________________________________________________________ What's for dinner? Visit www.cookography.com to find out!
