Re: FT8 for U3?


GIUSEPPE
 

Good evening everyone, I agree with what Jerry wrote, the WSPR propagation does not determine the openings in SSB, I have a beacon on 6m with a QCX MINI modified by me and I noticed that when in Northern Europe they receive the beacon signal the 6m band is closed, this also applies to all wspr hf frequencies, I also have 2 U3S for all hf frequencies and a QCX MINI for 20 and 30m.? Nigel you are right, WSPR is not suitable for vhf and above frequencies, no.? I've never seen a spot and then there would be a need for powers above 10W to get some listening.? In FT8 I don't know, I don't use digital modes, certainly in CW it would be the most ideal thing for a beacon.? 73 and good evening everyone

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.
