SDR - this is what I will do

I have struggled to build an SDR for the Arduino DDS board to tune. So I have decided to get someone else's design and mount it on an shield board.

The simple, obvious choice is the Softrock Lite ll from Tony Parks. This is a basic SDR which is what I want to build anyway, but it is debugged and ready to go. So here' what I propose.

1. Crop the schematic to accept an input from the AD9850 DDS shield I have built.

2. Then plan a shield like this

I have ordered a kit from SDR-Kits as Fivedash are out of stock at the moment - coming soon they say...

Can't wait to see how it goes.
