Meeting Presentation Topic

Deeper down the rabbit hole: HF, Doppler, Solar Weather & GPS
with Greg Albrecht W2GMD
Ever wonder how the sun and the ionosphere interact with HF propagation and GPS? Me too! In this presentation I'm going to take everyone on the journey of discovery I went through a few months ago when I asked myself how all of these things are related.
