[eagle] 70 cm Receiver - Replacing U8 made no difference

John,

Changing the second Mixer, U8 had no affect on the passband ripple. We've now replaced the matching network and the mixer with no change at all. What do you suggest for the next move?

Please see the Eagle Receiver page http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/U-Band_Receiver

Under Project Status I've started a new log titled Troubleshooting Resumes. It has before and after pictures of the passband ripple
