Maybe the timing was coincidental, but it looked like reddit was down for a few minutes after the earthquake (I checked some other sites to make sure it wasn't just my router being silly after power came back). Reminded me a bit of how almost every news website (barring Slashdot) went down on 9/11. I wonder how many sites could handle the load if a serious disaster happened. Makes me reconsider where I'll be able to get info when something bad happens

HAM Radio or SDR! It's worth picking up something as inexpensive as a Baofeng or RTL2832U transceiver, even just to listen on common frequencies.

I have one of those cheap RTL-SDR dongles that I use for listening to ADS-B messages. Other than listening to FM radio, do you know if any other good uses in a disaster situation?

FRS and MURS frequencies would probably be most ubiquitous and useful in an emergency. If you get a second SDR, you can "hop" and listen to trunked frequencies used by emergency services, local and federal channels. Or you could buy a scanner from Uniden for something a little easier. I can highly recommend the SDS-100 - https://uniden.com/products/sds100-true-i-q-x2122-digital-ha...

Find out what frequencies are used in your area for HAMs participating in disaster response.

Even better, get your ham license before you need it, and practice getting on the air with emergency nets and just to chat with fellow hams.

Any HN regular should be able to study for a few hours and pass the Technician test. This gives you access to all the VHF and UHF frequencies that are often used in emergency communications. A bit more study and you can get the General license, which lets you use more HF (potentially longer range) frequencies.

Here is a good place to start:

Many hams start with a cheap Baofeng handheld. These sell in the $25-60 range. Here's one I have and recommend - it's at the high end of that range but has several improvements over the cheaper ones including a better antenna:

Ham radio has been popping up on HN a lot lately. Besides emergency communications, there are a lot of interesting things you can do once you get your license. Feel free to holler with any questions!

This isn’t hyperbole. I got my Technician license after literally only studying for an hour (admittedly I had some prior experience, but most of what the test is just memorizing various things you should know).

Second this. There are a few study apps that make use of free time on the toilet for a few weeks and you’re good to go.

I have probably a dozen RTL SDR’s strewn about boxes and junk drawers, but the idea of relying on them in an emergency is unsettling. The little baofengs have a terrible interface but last a long time on a charge and are pretty rugged.

The point about practicing is legit. Most comms with these radios happen with relays, but you’ll want to know where people will be in simplex (walkie talkie style) operation if there’s no infrastructure.

I had the exact same thought also because of 9/11. I am in British Columbia and I got a vague provincial emergency alert saying there was no tsunami threat. Amazon Prime was also failing at the same time. Facebook was loading but then the USGS site was failing.

Remember the phones after 9/11? Long distance calls were touch and go for, IIRC, days. Barely worked at all day of, might get through on like your tenth try and then probably get disconnected after a minute or two. Good thing ICQ existed.

Relatedly, remember when long distance vs. local was something you had to consider when making a call? Hahaha.

In Japan during the 3/11 earthquake, the only way people were able to stay in touch was via Twitter and other online chat apps (LINE, Viber, etc). The phone lines couldn't handle the load.

Maybe the proliferation of more 5G towers could make the internet more resistant?

usgs.gov was returning 504 within 10 minutes of the event.
