Hi, I'm N1RPN and I'm learning to run RTTY using Cocoa Modem 2.0 running on a Mac G4, and Icom 720a and a 40 meter dipole.
But I see in the Wideband RTTY waterfall display a signal that appears as 3 signals side by side and interesting Lissajous patterns in the tuning display. Any idea what this is?
