Extreme-Lite Kit. Includes the PSDR2 PCB, Complete housing, and the few parts that you CAN'T get on Digikey.com . The remaining parts (about $200) are up to you to obtain. Great for if you already have some of the components, want to build it up a little at a time, or can get things for cheaper than I can.
Medium Kit. The ICs are soldered for you and the microcontroller is preloaded with firmware. The remaining components are included, but not installed. That part is up to you! This is a challenging kit, experience with surface mount soldering is required.
Really? I will sit in silent shock at your generous support, then I'll freak out a little bit. I'll fly myself to wherever in the world you happen to be and hand deliver your PSDR2. I'll speak at your club or school.
