Failure is always THE option.

Failure is always an option as the mythbusters were wont to say, but for me it seems more like failure is always the option. Built every module and tested each individually and then bringing it all together as a whole some of it refuses to play nice together. So, the idea of a multiband receiver might just get canned and i go back to making a single band receiver.

So what is wrong with it? Well, the rf preamp did not really work right. The bandpass filters were always crap, but that is an easy fix, the LO needs buffer amps to drive the mixers properly and the AF amps are kind of ok but i think need a little more gain in there and the attenuator, im not sure its even working. It makes noise but its nothing to write home about.
