I'm doing that right now, Andy. In fact, I'm doing it all on the
primary receiver of the RP-16. requires CWSL_Tee, CWSL_SSBWave,
FT8Start. I'm interested to hear that your spot count increased. The
one fly in the ointment here is that I keep getting these "image clusters".

Check out the Reverse Beacon Network

spotting RTTY activity worldwide.
For spots, please use your favorite
"retail" DX cluster.
