It sounds like, where you live, the municipality doesn't have an incentive to not inform you of late or owed taxes. The issue is that the government in this case has every reason to not inform the property owner of late taxes owed.
I've been a ham radio operator in the US for a couple years now, and its a really interesting hobby that will put you on contact with very smart inviting people. Its a great way to learn more about electricity too.
To experiment in radio on certain frequencies (like the ones needed to talk to satellites, requires a license from your nation's government, as radio frequencies are a shared resource. Certain levels of licensing is for 'amateurs' and other licenses are for more industrial things, like TV and what is commonly referred to as FM or AM radio.
Communication with satellites in the US requires the highest level of amateur licensing called the Extra.
