How can I filter DX spots with obvious typos like 280005.5?

You can apply a Band-Mode filter for each ham band that you would like to see spots on. However, be careful as this might keep you from interesting DX or SWL information. For example what if that P5 that you needed was spotted on 280005.5. The typo would not stop most hams from the chase.

Another example was that a few years ago, Air-Force One was spotted just below the 40 meter ham band. I tuned down and heard some very interesting phone patches. It seems that the high dollar military satellite phone system was down and they had resorted to using their HF backup.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
