The EI0SIX beacon is QRV on 50,004 MHz from IO63VE using a RFzero driving a RA30H0608 power module delivering 30 W PA to a Par Electronics OA50 omni-directional horizontal antenna. The EI0SIX beacon is part of the Synchronized Beacon Project (SBP).

From time to time OZ0RF operates a WSPR transmitter from JO65FS in the Greater Copenhagen area into a 1:9 UNUN connected to a 16,2 m longwire antenna. Sometimes the RFzero output is boosted to 27 dBm/500 mW. The actual location is nothing to brag about and a better locations will be investigated when time permits.

You can see the latest spots of OZ0RF on WSPRnet.org.

My WSPRmulti 20 x 4 LCD layout and rotary encoders allows me to select a pre-programmed WSPR frequency and multiplication factor on any of the 14 bands from VLF to 23 cm.
This screen contains all the necessary info to make a standalone beacon/signal source. I also integrated the GPS antenna on top.
A very useful package!

Warren, WA8TOD, has connected his RFzero to an ADF4351 using the RFzero as a 25 MHz GPSDO. This way Warren can make any frequency from 2605 Hz to 4,4 GHz. This is done in two steps: up to 200 MHz using the RFzero and above using the ADF4351.
