Interesting, thanks. I'd always been under the impression (maybe old folklore) that encryption wasn't allowed over some bands.

.. Now that I type it out, this is probably a band that has no rule for this.

Even if so, I can't imagine that anyone anonymously bolting radio equipment onto public property cares about usage rules.

Using spectrum irresponsibly harms usage by others.

Installing equipment for everyone to use is the opposite. No one is harmed by such installations.

Bandwidth is a finite resource. An installation that is open for everyone to use still harms other people who would like to use that bandwidth for other purposes.

That's assuming any traffic is being sent. Installing the hardware doesn't automatically cause any harm.

Installing hardware that isn't doing anything is just littering.

This assumes that whoever set these up made sure there is no interference and hikes up there to remove the device when it breaks instead of just leaving it up there to rot.

It would seem that hogging up spectrum so you can surf the internet is probably a selfish usage? I mean most ham operators don't go 24/7 while talking and using channels.

I didn't say they were harming anyone. They might be. Frankly I have no idea.

If they don't want the fcc or ham operators confiscating their gear they do.

It disappoints me that americans are seemingly so ambivalent to this particular government overreach. The same thing appears to be playing out with drones now as well.

That’s not what ambivalent means.

You can easily do it legally easily, ham test is slightly harder than a written driving test. Basically just learning what emergency bands not to stomp on.

Do ham operators have some special privilege enabling them to take private property without being charged theft?

You would be amazed at what ham operators feel like they can do.

I think ham radio is super neat and good enforcement of the rules makes the space better overall. I've also got lots of friends who are passionate and dedicated hams who've shown me the thrill of chatting with someone continents away over the open airwaves.

... but I get huge hall monitor vibes from a disproportionate percentage of folks in that crowd. For some it seems like it's not about using rules to protect the airwaves– the rules become an end themselves.

Looks like they don't care that much. If they did they probably would have put contact info on it.

Also, theft of one of these things is probably a criminal charge regardless of what rule someone was breaking with it. I'm a licensed motorcycle operator. If I see someone irresponsibly biking in a national park, I can't just take it when they're not looking.

The ISM bands allow encryption. The HAM radio bands don't (except for satellite command uplinks).

Transmissions to any remote controlled craft - RC planes, cars, etc. in addition to satellites - can be encrypted.

Amateur radio bands do not permit encryption, but they do permit digital modes to varying extents.
