Or download and use a program such as gqview (Linux, Mac OS X, Windoze) to display.
Additional propagation maps have been posted on the Gran Fondo Virginia 2013 and Boys and Girls Club Cycling Challenge 2013 public service event pages.
The following link gives S-meter readings vs field strength in dBuV/m or received power levels in dBm. This will be useful to interpret maps which will follow.

Splat! HD quirks:
Don’t put a “.” in the name of the repeater (.qth filename) such as WA4TFZ_146.760 as this will excite the bugs in the software (it will try to find WA4TFZ_146.lrp and fail).
Convert the files from ppm to jpg and modify the kml file accordingly.
The resulting maps can really slow down googleearth.
