Arduino and WSPR from 100 kHz to 1 GHz

We are very excited to announce the RFzero - a multipurpose Arduino RF platform that can do WSPR from 100 kHz to 1 GHz in a cost effective way and at the same time with a responsible RF spectrum and stability performance.

For more information please visit http://rfzero.net

You can use one of the dozen example programs or tweak them to fit your specific need for WSPR but also for CW, FT8, JT9 or PI4. Soon we will also have an example program for a QO-100 dual LO solution.
