| + | In conclusion, even though I could not implement a fully functional radio, I feel that I created a useful system that will be an integral part of my home. We've long struggled with waking-up early in the winter and it was always an issue to close the plant lights when we were gone for a longer period of time, so this might be the end of those problems. | ||
