Transmitting and Receiving EM Signals


I am new to electronics and I have a project I would like to start, but I am not sure where to start.

I would like to make a small project for transmitting and receiving various frequencies of EM waves/signals. I think the Arduino would be good for helping me with this, but I'm not sure which kit to get. I'd like to test a wide range of EM signals, is there a good starter kit for that sort of thing?


What exactly do you mean by EM signals? What range of frequencies have you in mind ?


Sorry, but the Arduino is not a good place to start learning about EM waves.
