10m WSPR RX (WISPY)

This was designed 10 years ago as a simple 10m WSPR RX. Later, with slight changes, this became the 10FT8R FT8 receiver that appeared in RadCom. 

The design is very simple and used low cost crystals either for WSPR or FT8 RX. It is a direct conversion RX so will also pick up signals on the other sideband. It is extremely unusual for this ever to be an issue. Lots of stations have been received.  

On a simple PCB, it would make a low cost, simple, and useful club project.
