Since 4 January 2019 the SK3SIX beacon has been using a RFzero.

The typical use of the RFzero is as a beacon (IBP, SPB, CW, FT8, JT9,
PI4 and WSPR), Qatari Oscar 100 dual LO or as low cost 10 MHz GPSDO. A
dozen of example programs (sketches) are integrated into the Arduino IDE.The RFzero can generate frequencies from 2605 Hz and beyond 200 MHz.
