HF Propagation Forcast

[daysand]

WOW !!!
This is Absolutely the VERY Best Propagation Forcast that I have ever seen. It is for Tropospheric Ducting . Tropospheric Ducting Forecast for VHF & UHF Radio & TV

Are there any HF Propagation Forcast, that are as good as the Tropospheric Ducting?

I have searched for years to find a very simple direct Propagation Forcast for HF.

To this day I have NEVER found a HF Propagation Forcast that is any where close to the simplicity as the Tropospheric Ducting Forcast. Tropospheric Ducting Forecast for VHF & UHF Radio & TV

Could somebody Please, locate and Post a HF Propagation Forcast site that is like Tropospheric Ducting
site. PLEASE !!

I kinda doubt that you'll find anything like that for HF, frankly, although it could very well be out there somewhere. Part of the problem is that we're somewhat in uncharted territory with solar activity. It was dormant longer than anyone had anticipated, and only now are we seeing the (fitful) beginnings of activity increases. All the models are having to be redone, no doubt.

The sun plays a major part in how HF works, so until this gets all hashed out - I doubt it will ever be done to everyone's satisfaction - forecasts will likely be very limited in scope.

I find the Tropospheric Ducting Forecast for VHF & UHF Radio & TV to be HIGHLY innacurate. Maybe only 15-20% of the time does it provide reliable results. On VHF/UHF, I tend to rely more on VHF Propagation Map

If you want something that's only 15-20% (which you've qualified as "Absolutely the VERY Best Propagation Forcast" ), I'm sure you could put something together.

Well, the link from the OP shows "Forecasts" and not a "this is what is going to happen 100%" scenario.

For HF, you're better off looking here:

HF Propagation and Solar-Terrestrial Data Website

Also, VOCAP is pretty good if you take the time to understand it.

I'm not looking for 100%, but since you made this post, I have looked at it every day and compared it to my findings, and it has been 0% accurate during that time period from my location in Southeastern Massachusetts.....a forecast should at least have some reliability.

What are you looking for in the way of a propagation tool? Any tool is simply a projection, and it will never be 100%, as you noticed. Typically you're better off understanding how sunset and sunrise times change propagation to your area, and what the flux, A and K levels are telling you. Anything else is, more often than not, a somewhat informed estimate at best
