DXHELP.EXE -- MS-DOS. SWL and Ham propagation aid.
This handy utility from WA5ZBC makes chasing that rare dx a bit easier.
Input your latitute and longitude, the target latitude and longitude, and the
solar flux index (obtainable from WWV broadcasts at 18 min. after each hour)
and the program shows the MUF (Maximum Usable Frequency) for that particular
day on an hour by hour basis, calculates the distance and bearing in case you
have a directional antenna. Helps you pick optimum times to look for the rare
one, and lets you know when it looks like propagation will just be zilch to
that particular area on a given day. Good timesaver..
