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?
Doppler shift.
That's is also why WSPR is crap when the path passes the polar zones.
Haven't you noticed that the successful reported wspr paths tend to be only basic north and south
or east to west or vice verce paths ?
Shove an interesting path that *traverses* either the north or south auroral zones and it turns
to complete crap.
What's the bloody point of sending? 6Hz wide signal across a path that smudges the signal by 30Hz ?
Hard facts dude.
There's another more useful? mode built in to all the all the QCX/QMX/U3S kits.
Seek and you will find.
