There are two types of license: Amateur and Commercial (I've had both), each with specific requirements. In the commercial world, it is illegal to disclose or repeat messages received without permission, and keeping them private is a mandate. In the amateur world, communications are public and for experimental/entertainment purposes. Encryption is prohibited. Maybe because it can't be a threat to established governments. In the old days, ham radio communications were possible to some pretty restrictive locations, though getting a license there may have been somewhat restricted too. Casual conversations were possible with people behind the wall. Nothing important could be sent on ham channels; that's what commercial channels were for.<div>
<br></div><div>[Health and welfare messages are not "important" in this context, but are common traffic for hams.]</div><div><br></div><div>There's still lots to learn that requires a ham license. With a license, you can use larger antennae and more powerful transmitters than without. At St. Charles LUG, there was a presentation on instrumentation for amateur rocketry that required a ham license. Very interesting, and shows some of what we can learn.</div>
<div><br></div><div>One topic that's lots of fun is testing how far you can go with 802.11 2.4GHz communications. Might be hard to break some of the standing records, but putting additional restrictions can make it more challenging. Improvising an antenna system and testing it is a technical exercise.</div>

The biggest issue with the ham license is that you aren't allowed to use encryption. I'm KD8EVV but haven't had a radio turned on in years.</blockquote></div></div></div></div></blockquote></div></div>
