A Six Metre Rx Converter

A Receiving Converter Based On An Elecraft Design
The receiving converter circuit below is based heavily on that of the Elecraft XV-50 six metre transverter. The PCB images below are of the finished circuit.

Even though we had to endure a 40C plus heat wave over the last few weeks I got into the shed early and drilled some PCB including the one above before it got too hot. I spent all of Saturday assembling and testing and it works quite well with about 20db of conversion gain. I had to make some modifications on the fly during testing and debugging but no major changes. As expected, and due to the extra filtering, the unwanted signals at the 28MHz I.F. output are less than they are with the simple SA-612 converter described further up this page.
