Can a hacker intercept the radio signal?
Yes. Any radio that can tune to the proper radio band can receive the signal. Putting together all of the pieces and reading what you are sending or receiving is very difficult but possible. Lucketts.net will use various methods and tools to give the hacker a hard time, but we cannot guarantee absolute security of the data link, which is why you need to use secure https connections when banking or buying things over the internet.
