I think a lot of young(er) people like me who would otherwise get into ham radio are being sniped by SDR. You can buy a $30 piece of hardware and listen to planes talking to the airport, see weather imaging from satellites, intercept and read pager messages, listen to emergency and police radio, listen to all channels of consumer grade walkie talkies, and also just generally see the invisible world of wireless commun…

Specifically you're talking about RTL-SDR, a hacked soundcard that can receive a lot of frequencies. The channels you can legally transmit back on for a few hudred dollars more are FRS/GMRS family/business radio channels. (Speaking about USA only here, since that's the only radio location I know about). tl;dr for the rest of my post: ham radio is the best type of radio for hackers. Undoubtedly you can have tons of fu…

RTL-SDR is a TV tuner, not a sound card.

You could build a radio that transmits on FRS frequencies, but it would be illegal unless you submitted a radio to the FCC and received type approval. FRS radios must be type approved, limited power, and with non-removable antennas.

I think GMRS radios must also be type approved, but they can have removable antennas. You need a GMRS license to operate one legally. FRS does not require a license.

"...breaking in on the Chik Fil A drive-thru attendant..." Seriously? Come on.

Other than those nits, you do have a lot of good information in your comment, so thank you for that!

A timely blog post for me: A close friend who is the same age as me (and an EE) has been trying to get me into Ham for over 10 years. I finally became interested and bought a $25 radio (BaoFeng UV-5R) on Amazon ... only to learn that I couldn't talk to my friend on Day 0 because 1. he lives >20 mi away, 2. no line of sight and had to learn about repeaters, and 3. I have to learn technical and cultural nuance of Ham b…

> 3. I have to learn technical and cultural nuance of Ham before being allowed to speak

Could I ask what this item means? That you needed a license, or is it possible that the repeater somehow enforced a class?

I hate to be the one to break it to you, but no one cares what GenX thinks. Apparently we didn't throw enough temper tantrums as children.

It's hard to agree with that line of reason. In my observation, GenX marketed themselves as the generation of apathy, and so eventually people became apathetic about them.

I think GenX didn't believe in marketing themselves. The concept makes this X-er chuckle quietly.

I saw this shared on Twitter this morning, and had some thoughts: While the graph is good, it is specific to the US and ignores the fact that a large amount of the amateur population is 50+ - the hobby is healthy now, but there's an age crisis coming soon. It doesn't really reflect the health of the entire hobby, globally, just a specific subset. Millenials aren't young any more, I'm millenial and I've held a ham lic…

Here in the UK, we've seen a huge surge in people - especially younger people - getting licensed since lockdown, in large part because it's now possible to take your license exams online. I think that the RSGB (our ARRL) had severely under-estimated the amount of friction in the old examination system and the amount of pent-up demand created by things like RTL-SDR.

I'm curious as to why you would bother with HAM. It used to give you something that wasn't available otherwise, but that hasn't been the case for a very long time. There are plenty of ways to communicate with whoever you want, however you want, whenever you want and completely encrypted too! I see a lot of anecdotes of special distaster cases when HAM was the magical solution, but I don't remember normal communicatio…

Because ham radio is fun. It's a different hobby than the other myriad ways of communications which you describe. It's a radio service explicitly dedicated to the personal enjoyment of radio. It is not a personal communication service in the likes of FRS, GMRS, or even part 15 (wifi), microwave, or cellular networks.

Think of ham radio as a sandbox for radio experimentation. There is a LOT to ham radio that you've overlooked.

It is however unfortunate for many commenters on HN is that encryption is not allowed on amateur spectrum, but it's important that it stays this way. The amateur radio spectrum is worth billions of dollars to the telecom industry, but we've been fortunate to have it protected by the FCC (in the US) and international agreements. If encryption were allowed, there would be no reasonable means of verifying that a communication on ham radio is compliant to its regulations, especially those preventing communications of a pecuniary interest. In other words, encryption would open the doors to telecom companies and other businesses to use amateur spectrum instead of acquiring a license for radio services that would otherwise suit their needs, i.e. an illegal workaround to save money from licensing fees. Encryption also puts a downer on the spirit of ham radio, which is built on random conversations between the technically minded folk on ham radio to share information and knowledge of ham radio itself. You can't drop in on an encrypted conversation.

There could be changes to regulations that would mitigate these concerns (for example periodic unencrypted plain text/voice identification, private keys made public and broadly shared, etc), but such changes would be hard to come by, especially blocked by international bureaucratic processes, and a lot of the "old guard" fearful for the state of their hobby were encryption to be allowed.

Ham radio also has a broad base of experienced communications volunteers, which comes in handy during earthquakes, hurricanes, rural/remote search and rescue, in which the amateur service supplants ruined communications infrastructure while telecommunications companies and governments mobilize their recovery efforts. Examples include 9/11, Hurricanes Katrina, Maria, Irma, Andrew, and more, numerous fires in the west US, earthquakes of Haiti, Iran, China, and Indonesia; and even plays a role in ground-truth tornado spotting and tracking.

What happens if I use SSL over the top of such a network? Is that allowed? If the answer is yes, it seems more like a loophole in the rules than anything.

Probably not. These rules were put in place to prevent spies from using HAM to exfil data during the Cold War. Really I think it should be something that should be revisited but I don't know how the 3 letter agency's would like a method of communication that they can't access.

Is that the case? Most spies use/d OTPs which can be used without encryption as per se. (VENONA notwithstanding)

Why do people buy vinyl records or ride horses?

There's something completely magical about making an inter-continental contact with 5 watts and a wire in a tree, or bouncing your voice off an amateur-built satellite with a handheld yagi. There's an eerie beauty to the atmospherics on the HF band, the music of signal emerging from the noise. The anticipation of the dah-dit-dah-dit dah-dah-dit-dah of a CQ call, the excitement when a rare callsign weakly breaks through, the frenzied pile-up of operators jostling to get their QSL. The bizarre geopolitical madness of 7055kHz.

Hardly anyone needs to use amateur radio, but it can be a tremendous amount of fun.

My 5G mobile PHONE can provide me with 200MHZ of bandwidth and frequency range from 400 MHz to 7 GHZ So yes, HAM is DYING because outdated legislation is denying me same goodness in my mobile 6Watt radio.

but an amateur license potentially gives you access to 1.8 mhz up to beyond 10ghz.

There are allocations below 1.8 MHz now.
