Pileup Runner is a simulator of DX pileups. It is intended for the DX-pedition operators and those who are curious how the pileup looks and sounds at the DX side.
Compared to Morse Runner, which is a contest simulator, Pileup Runner has an extra dimension: frequency. In this program just working the callers is not enough. To be successful, you also have to tune your receiver through the pileup in a smart way.
The program is freeware, currently in the beta stage. Grab a copy at (http://www.dxatlas.com/PileupRunner)
