More and more DXpeditions lately are providing some form of propagation prediction software that can be customized to a user’s QTH and station (antenna) configuration.
The latest DXpedition to do so is C82DX via their website here.
Although I’ve noticed similar programs on other websites, I haven’t really paid much attention to them.
Instead, I’m more likely to do a search of my own logbook for the Zone in question to see what times and bands I’ve worked stations there – but this may be a better way to get an idea of ‘bands and times’ regarding areas of the world that aren’t particularly active.
I just worked C82DX on 40m about half an hour prior to my sunset. Their prediction program said I should hear them just above “Nil” at S3…and that was about right.
A similar program, VOACAP, gave me a 0% chance of working Mozambique at that time on 40 meters.
Moral of the story – propagation predictions should be regarded as one would a weather forecast. Their value is not in predicting how conditions will be, but rather how they are likely to be. . .
