Jay, KB8O made a video showing S52D’s diversity patch for WSJT-X using his Icom 7610 and DX Engineering 4 Square receive array. KM8V also has it running with good results. The patch is pretty interesting. With just one receiver, you can get some additional decoding assistance from the time diversity. If you have two receviers and two antennas, you can benefit from the frame diversity, and if you have a rig with two receivers like the Icom 7610, you can also do space diversity. Check out Jay’s video above, and more details can be found in Iztok S52D’s PDF document.
