Hello group

If you are looking for a stand alone solution to transmit digital signals like FT8, JT9, PI4 or WSPR from kHz to GHz then the RFzero might be just what you have been looking for. The RFzero is an "extended" Arduino Zero, with GPS and more, so you can modify the software yourself if you like.
