I wonder if Max Derouer (he wrote the Etrac Emulator) or anyone else will come up with one for the CTX. It would be nice to make changes to the program you are running and see how it affects the Fe and Co numbers while at the comfort of your computer. I went outside with the CTX to try a few changes on targets and was soaking wet in a few minutes. Temp in the 90's and very high hunidity. No relief for at least another week. Temps in the 100's this week-end. Oh well!
