“Any station, any station, this is the International Space Station,” Wheelock said.
EPIC! I bet most ham radio operators who heard this thought it was a joke :) Someone should make a movie/show about this ^_^

There was a book about a kid who wins a contest to get sent to the ISS, and connects with an african boy over ham. I do not remember the title, but this reminded me of that.
whoa id love to hear the name of it!
hah I remember reading that as a youth (must have been 20+ years ago) but I can't find the title either. More recently I read Seveneves and it's also got some ham radio worked into the narrative.
I don't know about a book. But this reminded me of a good new movie "Cosmos (2019)". They used custom made hardware/software to find a signal from space. IMDB Summary: "Cosmos explores the thrilling first hours of first contact when three astronomers accidentally intercept what they believe to be a faint, coded signal from a distant alien civilisation." https://www.imdb.com/title/tt4477292/
It's Countdown, by Ben Mikaelsen! I also read it as a kid and my google-fu was failing me. Had to ask my mother - long-time public school librarian - if she remembered the title (of course she did!)
A fun book. I'll have to see if the local library has it for e-book loan. I hope it stands up to my childhood memories of it.

Thanks for the title, will check it out :-) It's $5 used on amazon. https://www.amazon.com/dp/0786812087/
Sort of a goal of mine has been to bounce off the ISS APRS digipeter at least, but building a satellite aiming rotator setup has been my hangup, although in theory I could try handheld yagi? I would like to make a rotating setup though for general satellite work tho.
I'd like to do the same thing. I have a goto mount telescope, and I've used this software: (https://heavenscape.com) to track the space station with the telescope. It's a little tricky, and you don't have too much time to realign the mount etc if something is wrong, given that the ISS passes usually only last a few minutes, but I did manage to get it to work after a couple of tries. If I had to do it again I'd practice with other random satellites first.
What I've been thinking about is coaxially mounting an antenna and using the telescope mount as an antenna mount. The only problem is that you do need a telescope on the mount to shoot some alignment stars, so you can't just mount the antenna, and I don't know how much the metal in the telescope would interfere with the antenna.

I've had good luck with a handheld D74A and a handheld arrow yagi. I don't make it in every time but I've hit it successfully a few times.
Try it handheld first. It won't be perfect but you'll hear the APRS and get a feel for how (not) precise it has to be. You're going to need the antenna either way. It's impossible for me to convey how extremely janky my first DIY antenna was for this. It's not a super-precise operation: https://www.youtube.com/watch?v=2y6A6ur7yas&t=520s
I have managed to do this without a directional antenna. I just kept trying. Using nothing more than a dual band vertical antenna in my attic with 50w power.
There's a low-cost tracking antenna mount that's quite popular for first attempts, known as "a friend".
You lash an inclinometer to the boom, and hand them a compass. Tell them where the pass begins, and hope they can acquire it visually after that.
The hardest part is doppler correction, really. Get the software for that squared away well in advance.

reading this got me interested in getting a ham radio. anyone have any cool experiences they can share?
For me it’s really cool just to be able to speak with someone halfway around the world with no infrastructure other than your radios.
you can decode satellite images as they cross overhead you with a cheap handheld or $20 sdr (https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...)
i personally do a lot of digital mode stuff with really low power (<1 watt), with a small antenna inside an apartment and sometimes get really far contacts (relatively speaking for my setup) on things like WSPR

thats sweet. what type of images do you get? is it just weather?

I've only ever heard of weather images. The Thought emporium has made at least four videos on the subject, showing progressively more complex builds.

Park your sdr on 14.230 and load up an SSTV decoder, and let the sweet, sweet bikini pics roll in.
I enjoyed using a $20 rtlsdr dongle to listen to phone calls on the iridium satellite phone network using a window pointed antenna made out of scrap wire, a stick of balsa, and a milk bucket, http://erewhon.superkuh.com/milk-bucket-1626MHz-helicone.jpg The https://github.com/muccc/iridium-toolkit made it easy.
It's not an amateur mode but is something you can do as an amateur. And it's actually easier than decoding weather satellite images.

whoa, so are you just listeing to casual people's conversations? thanks for this!
In practice it's mostly robot voices reading off things like how much credit people have left on their accounts or the state of the voltage charge of some battery. Same for the pager texts. But yeah, occasionally you get a handful of seconds of an actual human's conversation being downlinked from the satellites passing by.
For me, it's about safety.
I live in an area [0] prone to severe weather and especially violent tornadoes. The local Skywarn [1] repeater is probably the best source of immediate first-hand information when things get bad. There's usually at least a few storm chasers out following the storms, and reports from various places in the area help you get a real feel for how bad a particular storm is.
Moreover, the repeater is monitored by all of the local TV and radio stations as well as the city EMA (Emergency Management) and the local National Weather Service office. So you're basically getting first-hand information directly from the source. I always have my radio on during severe weather and keep one in my truck as well.
It's not difficult to get a license, either. A reasonably intelligent person can self-study for the technician exam in about a week and you can get a decent handheld for less than $100.

I lost a fuel line in a place with no cell reception. It was pretty cool to sit back and wait for help after calling on my ham radio. Yeah, not as cool as satellites, but it can be a very useful hobby, even on a budget.
Also, from areas without cell service, sending a text message from a radio to a phone is pretty cool. Even the teenagers were impressed with "old man" technology.
No affiliation, but check out hamstudy.org

Maybe it is obvious, but apart from the equipment you need to pass the exam and get a license.
No one's mentioned it yet but if you do find a numbers station they are rather cool, although they are increasingly rare.
Contesting. See how many contacts you can make in a certain time. Compare your score with friends and rivals. Improve your station. Does it help your score improve?
Satellite grid chasing - using amateur satellites to contact every “grid square” in the country.
There are also awards. Some are easy to obtain (confirmed contact on any band with 100 countries), but can you work the world on just one band?
Don’t like talking? Digital modes eliminate pesky talking.
Want to learn to solder? Make your own antenna. Make it better. Make it bigger.
Have friends nearby with radios? Use your radios as direction finding equipment and have a “fox hunt”. Find the hidden transmitter!
Are you an insane conspiracy theorist who believes the covid vaccine will turn you gay, blind, and autistic? Boy do I have good news for you. 75m band is chock full of yokels, Magas, and covidiot gun nuts for you to trade insane rantings with.
Should I keep going?

Ham radio has something for everyone, there are many hobbies within the hobby!
For me personally it is Morse code on the shortwave frequency bands, often with very low power, with battery driven gear operated from the nature. Morse is still very much alive and - most of all - fun. I like to compare it to playing and listening to music.
There are many active mountaineers (https://www.sota.org.uk/) and nature lovers (https://wwff.co/) who take their radios with them and have fun "activating" summits or nature reserves, and on the other side there are many guys hunting/collecting these activations.
There is a great feeling of community between those pursuing similar goals and many life long friendships have been formed through ham radio.
As I said, this is only a tiny fraction of what ham radio is all about, but the one that I personally love.

I hadn't heard of WWFF before. In the US, Parks on the Air is pretty popular.

Shortly after I got my general license, I set up a ZS6BKW antenna up in some trees in my yard, made from wire from Home Depot and some ladder line from my local ham store. One of my first contacts on WSPR was a research station in Antarctica, all the way from Colorado! Just with some hobbled together wire in trees. That got me hooked for sure.
Ha wow astronaut Owen Garriot was Richard Garriots father. Richard Garriot is the creator of the Ultima series of video games that I owe my childhood and love of programming to. Small world!
Richard Garriott also took some of James Doohan's ashes to the ISS at the same time as his trip up there.

I was lucky enough to participate in one of these "educational programs". When I was in 6th grade I was selected to learn HAM radio and ask a question to the astronauts aboard STS-93. The program was called "Shuttle Amateur Radio Experiment" (SAREX). Long live SAREX!
I recently took my amateur ham exam— fun fact: broadcasting music on ham radio is forbidden unless it's incidental to some broadcast from a space station.

Another fun fact: you aren't allowed to cuss!
"Goodbye Lenin" fictionalised the ordinary return to earth of a GDR astronaut as an incidental taxi driver in part of the plot.
It's nice to remember they're people too, even in space you can get the glums, feel like a random connection might be what you need, capcom or not.

There's some great footage of two russian astronauts talking about how much they don't like space while in a Soyuz before docking. I'm on my phone so I can't find it.
I think Scott Kelly is next to them, it was his last trip.

I assume getting there is the worse part of the trip. Even if you're on a Dragon capsule
Ok, getting off the station is probably very stressful and annoying as well, but at least you're going back home

The last few meters are also rough:

Cosmonauts... sorry!
and "Red Star, Winter Orbit" fictionalizes an extraordinary return to earth of USSR cosmonaut :-)

I'm totally against people greediness. We have here on the earth so many problems what we have to soft out first.
Example: we are hysterics of this "pandemic", while tens of thousands die only in USA for drug overdose, cold, hunriness and so.. Not even mention how many children's are missing.. Those should be our priority. Naah, covid, wars and political shitty take the priority. Please people, stay out of space. We as humans.. We ain't ready for it.
