I just looked at both Glen Clark's 2007 APP and Cynthia Jacobson's 2023 APP for the Skywave near Pellston, MI, near my receiving location. I looked at the skywave elevation angle at my distance for each Night Pattern, and they are quite close. So Northern Michigan will continue to have a peak 6% skywave of about 4.7 mV/m. I'll test that with the FIM-41 when I get a chance.
