[Skimmertalk] WSJT-X/FT8 skimming: high PC CPU utilization limiting count of spots

[N4ZR]

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".

73, Pete N4ZR
Check out the Reverse Beacon Network

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