Here is a nice on-line application from VOA. It only goes down to 1 watt but you can select the location lat/long and antenna. Uses current progation data.

Have fun!

Based on today’s propagation and time of day, I would have a 20 to 30% chance of being heard in the Caribean and North Georgia and South Carolina. Now keep in mind that 1 watt is over the limit but does give you an idea of what is possible if the FCC would open this or 6.9 to 7 mHz to experimenters. Also at 13 mHz the ground wave locally would be nil.
