Eclipse and FMT Results from WA5FRF

[Nathaniel A. Frissell]

Hi HamSCI,

Steve Cerwin, WA5FRF, recently published nice Eclipse and Dawn/Dusk observations of WWV and WWVB in QEX. He does a nice job showing the observed dawn/dusk Doppler shifts and increased frequency variability/jitter at these times. He also shows nulls in the received WWVB signal at dusk and dawn which he says is consistent with destructive interference from multipath from competing ionospheric and ground wave propagation at these times.
