WSPR is great for determining propagation conditions for digital communications like FT8 but really isn't all that useful for determining if conditions are great for SSB voice, at least that's what I've experienced on HF.? WSPR can seem wide open and voice communications aren't possible.? In my opinion CW beacons are best for determining if voice communications are possible and that both beacon modes are useful.
I wonder why WSPR is less effective at VHF?? Is it due to the more rapid fading as opposed to the almost 2 minute frame for WSPR?

Hi John,
From research undertaken seems that WSPR on upper VHF bands for DX propagation is not very effective. Have found more than one study / paper that arrives at the same conclusion.
