Am I understanding correctly that this is just a normal raspberry pi with no hardware designed for sending and receiving radio frequencies and someone got it to do it without adding any hardware to it?

Only for transmitting, but yes. It uses only on-board hardware for generating signal, think it's using the same part that allows to output composite video via headphone jack if I remember correctly. RTL-SDR can be used for simultaneous TX and RX, GPIO for sending and RTL for receiving

That's incredible, I never considered such a possibility.
