Radio Wave Animation

Adobe After Effects continues to baffle me.  I created a radio wave animation in class and have tried to duplicate it at home without success.  I will have to keep trying and see what I can do.  Better notes might help, although I thought I took pretty good ones.  This is a work in progress... to be continued...
Well it is finished.  I am still not pleased with my final product but after many hours of working on it, rendering, and re-rendering I am calling it good.
