[MRCG] Net Propagation

[Tim]

Thanks Jim - Those fo graphs take the "Bugga Bugga" out of trying to
understand when, how and why the "band goes long" for a given freq.  For
local NVIS (central CA/NV) from the Pt. Arguello sounder they pretty much
tell the tale and are reliable predictors...
When looking at an all-HF SDR waterfall you can clearly see the sounder
sweeping linearly up across the HF spectrum..until it peters out at the
higher freqs and heads off to Space.....cool...

Cheers!
