The article "Eavesdropping on Apollo 11" from the American Radio Relay League (ARRL) website details an intriguing story about Larry Baysinger, a ham radio operator and amateur radio-astronomer, who successfully detected radio transmissions from the Apollo 11 astronauts on the Moon in July 1969. His remarkable feat was documented by Glenn Rutherford, a reporter for the Louisville Courier-Journal, in an article titled “Lunar Eavesdropping: Louisvillians hear moon walk talk on homemade equipment.” Baysinger used homemade electronic equipment, including a 20-year-old radio receiver from an Army tank and an antenna made of spare pieces of aluminum, nylon cord, and chicken wire. He was able to record 35 minutes of conversation from VHF signals transmitted between astronauts Armstrong, Aldrin, and Collins. This also included President Nixon's message of congratulations. Baysinger's antenna for this project was a fully steerable 8 × 12-foot "corner horn," noted for its exceptional sensitivity, which he had specially modified. His work gained brief recognition, including a meeting with the Collins Radio Company, which supplied communications systems for Apollo spacecraft. However, the story eventually faded into obscurity, preserved only in microfilm archives of the Courier-Journal. The article also details how Baysinger's interest in radio led him to a career with WHAS 840 AM radio in Louisville. His lunar eavesdropping project was motivated by a desire to independently verify NASA's information about the Apollo program and possibly uncover unfiltered details about the Apollo 11 landing. On the night of the Apollo 11 landing, Baysinger and Rutherford had to manually aim the antenna at the Moon, which was challenging due to cloudy weather and the Moon's motion. Despite the noisy signal, they were able to hear the astronauts' conversations, which were broadcast on TV without any edits or omissions. After Apollo 11, Baysinger did not pursue eavesdropping on other Apollo missions and moved on to other projects. The article raises the question of whether other similar lunar eavesdropping projects were conducted by amateur radio operators. It mentions only one other case of independent detection of Apollo transmissions from the Moon by Sven Grahn and Richard Flagg during the Apollo 17 mission, using a 30-foot radio telescope dish.
I agree. You can do it with that radio no issue. The big challenge is speaking WITH the crew of the ISS (there is always a "ham" onboard) and getting a QSL card! My wife, who's a ham also, and I competed to which one of us would get the ISS first. That was in 2010. One of my more treasured QSL cards.
The problem is that this antenna is for 70cm and you want one which tunes to 2m as well. I have a dual band AY04 antenna which does both 2m and 70cm which I use for satellite.
i hit the ISS repeater while commuting to work with the dual band radio in my car, you don't really need a directional antenna if you get a pass at the right angle. I've done APRS via the ISS with a "quarter wave groundplane" antenna made of a so239 connector and some 10awg copper wire. It's doable!
I've done APRS to the ISS on a UV-5R with nothing more then the BTECH APRS cable, a phone with aprsDroid, and a upgraded antenna. I have one of the knock off nagoya ones but it apparently works good enough to hit the ISS. Although I couldn't really get anything to work when it was less then 25°.
I just set this up but I didn’t have the adapter for the antenna cable to the actual antenna. Hopefully tomorrow I’ll be able to try it out when they get here
New subscriber here. Can you hear astronaut communication or just h signals from earth hitting the ISS as a repeater? Thanks and keep up the great SDR content!
I think the general downlinks for station radio aren't easy to pick up. I've heard you can sometimes hear suit radios during spacewalks, or capsule radios during docking (on different frequencies). I missed the recent SpaceX docking but I might try listening next time there's something like that.
One or more of the astronauts are licensed hams. If they have time, they will get on the radio and call for stations. I spoke with a crew member of the ISS in 2010 on one of my radios. It's a pretty big competition as many others are calling for them also. You exchange call signs and signal reports and maybe a quick question, but it's no long conversation. You only have the opportunity while the ISS is in your visible sky. Once they get over the horizon, they're no longer reachable. The speed they're going makes that happen fast. It was a great challenge. It took many, many attempts. No special gear and a Technician Class licensee has the the needed license privileges.
The ISS Crossband repeater has a downlink of 437.800 MHz with a doppler shift of up to +10khz on acquisition of signal (AOS) and typically -5 to -10 khz on loss of signal (LOS). The ISS direct to earth frequencies are 145.800 MHz for the downlink, which is also the frequency you can receive slow scan television (SSTV) on. They also have VHF and UHF up/downlinks for APRS packet communication. I have recordings of one of the female astronauts communicating with school children during one of their planned contacts from last April.
I spoke to Kathy Sullivan aboard the Space Shuttle Atlantis some years back when I was in university, on one of the SAREX (Shuttle carrying Amateur Radio EXperiment) equipped missions.
The irony is I was watching the video pulled up the N2YO clicked on ISS and it was 1 minute away. Took a picture of the night sky and found it when I zoomed in on the picture. Blurry but I got it. Didn't have time to grab my Ham radio to listen for traffic but was funny with the timing.
Gabe, I have a video on my channel when I was working one of the satellites. The calls go by pretty quick, and you have to be on your toes when the satellite goes zipping overhead. It’s fun, and an interesting challenge as well 😊
You don’t need a yagi to hear the ISS. All you need is a high gain antenna that’s it. However, you need a Yagi to transmit. I listen to the space station repeater on my Yaesu 70 D. Just by leaving it by my window. You can use a basic Baogang radio and transmit with a Yagi antenna and reach the station.
I am surprised that there is a doppler shift in the signal since the signal is transmitting at the speed of light and the ISS is hardly moving compared to that. I know it’s true but I guess I need to see the math to comprehend it.
That antenna MIGHT give you enough oomph to hit the ISS repeater, I hit it all the time with just my Nagoya771 whip antenna on my Wouxun which is similar... I'd at least give it a shot. I can listen for you if want to give it a try.
@@digitalchaos1980 Mines an older UV6D and I was really surprised when I got a good signal report. Can't beat a genuine Nagoya antenna. I also used this setup to hit the AO91 ham sat and got a good signal report on there as well. Even got a QSL card!
Hey man you don't really need a powerful radio to transmit on. I just made a contact myself over the ISS repeater with a tram omni directional antenna and an ICOM 5100. Been lovin your projects man!
I told a coworker of mine I saw a video on the internet of a guy that points an antenna connected to a radio to the sky and listens to satellites and he would not believe it is real 😂
The only thing I need help with is the proper adapter to plug the antenna into the uv5r. I've looked at adapters online but am afraid of purchasing in fear I'll order the wrong one lol. Isn't it just a BNC connector? I kind of want to build my own yagi antenna though. Building antennas is a lot of fun. Thanks man!
The Yagi I have uses a regular old UHF Male / PL-259 / CB Radio style connector. Most Baofengs use SMA-Female as the antenna (so the jack on the radio would be SMA-Male). You can usually find a 4-pack of various SMA to UHF adapters on Amazon or eBay for $10 or less.
😂 The only conversations that I could listen it was DX radio amateurs. Is that or the astronauts have been too long in space, or one of them is my grandfather having fun in zero gravity 😂😂😂
Hey man! If you make a contact with the ISS, you can get a really cool QSL card from them. I bounced a packet off of it with APRS and it got me a card.
You have to mail off a form with the dates/time/proof you contacted ISS. Super fun. I'd provide more info, but Its been so long I can't remember. Best of luck to you! :)
I didn't get a qsl card, but I did get an ACK, 73 from a station that APRS listed as over 7000 miles. That's 2.5 times the distance I've reached even on RS-44.
Transmitting via the ISS isn’t that complex, it’s more difficult to find a bit of free air to talk as it’s piled up on every pass. APRS via the ISS is much more doable (and I’ve done that loads) but there’s way less kudos doing that.
Flat earthers must say that there is a government official responsible for answering amateur radio messages in order to maintain the lie that the earth is round.😂
They also claim that satellite communications are actually weather balloons. Imagine launching 30k weather balloons per day to simulate the observable effects of satellites orbiting.
imagine the first thing you listen is "houston we're going down, we are going down.... so this is the end. tell my daughter that I won't be coming back with the milk.."
Hey man I've been wondering just for educational purposes, but could you conceivably work out the distance and location of something like the ISS from it's radio signals or is that not possible?
Здравствуйте! Вы могли бы сказать, размеры, расстояния в сантиметрах от самой приёмной части антенны (коротенькой трубочки до самой антенны (рефлектора)? Спасибо!
I don't have it in front of me to measure, but it should be the same as this one: www.amazon.com/TWAYRDIO-Antenna-400-470Mhz-Outdoor-Transceivers/dp/B08FC7JVQG?tag=namespacebran486-20
I know this post is old but Do you need a ham license to use the basic baofang antenna? Because i have a camp with barely any service and this would be nice to have
I'm not finding the exact same one, I bought it a little while ago and these darn imported gadgets change names every few months. This one is similar but a little more expensive: www.amazon.com/TWAYRDIO-Antenna-400-470Mhz-Outdoor-Transceivers/dp/B08FC7JVQG/ Or on eBay: www.ebay.com/itm/264751880402
They're radio amateurs giving their call signs, the station goes over so quickly and so many people want to use it that they don't have time for much else.
It can be surprisingly tricky, I've had mixed luck getting the timing and aiming just right. If you're in a city or near trees or hills it can also limit reception. I've had commenters say they can hear the station with just a regular rubber antenna that comes with the radio, and others who say they can't hear it at all. I had to make sure to coordinate the positioning with n2yo.com and double-check if the repeaters were active via www.ariss.org/current-status-of-iss-stations.html
Can you please help me. I confused of what to buy for baofeng uv5r. I see some comments on Amazon that this product is a ham radio, walkie talkie etc. I need to get a ham radio that is transceiver. That I can afford budget less than $30. Thank you
There are a bunch of Baofeng handheld radios, the model numbers don't always mean much, but they should have the specs on the back under the battery. Most of them will do 2M (VHF) and 70cm (UHF) frequencies. Some will do 220mhz which is a more obscure ham band that doesn't get used much.
Hi I think that this is awesome. I would like to do this, it would mean a lot to me if you could please link the exact equipment that you used for this. Thank You!
Oh ok thank you I really appreciate it. I have one more question. Can you use this technique to listen to radio waves from comets and meteor showers? Thank you!
Not that I've noticed, it's more about the radio frequency than the audio frequency. The sound is coming in the same, it's jut coming in at slightly different spots on the radio "dial" as the source moves.
The sound is not "encoded" it's straight up FM analog voice. The doppler effect is about 5-10 KHz high when the ISS is approaching and as it goes overhead or closest point, it is on center frequency. As it begins to go away the doppler frequency gets lower so it starts dropping about -5 to -10 KHz as it is passing. FM signals are wide band and channelized so you don't really notice a pitch difference. You'll either get the signal or you wont. If you listen to a linear satellite that uses single sideband modulation instead of FM, with a linear VFO, you can definitely hear the doppler effect alter the pitch.
"The earth is flat and satellites arent real" meanwhile hobbyists:
One hobbyist actually built a rig to receive audio from Apollo missions. NASA was so impressed, they came by to look at it.

Not that I've noticed, it's more about the radio frequency than the audio frequency. The sound is coming in the same, it's jut coming in at slightly different spots on the radio "dial" as the source moves.
@@saveitforparts ah! That makes sense. Thank you.
The sound is not "encoded" it's straight up FM analog voice. The doppler effect is about 5-10 KHz high when the ISS is approaching and as it goes overhead or closest point, it is on center frequency. As it begins to go away the doppler frequency gets lower so it starts dropping about -5 to -10 KHz as it is passing. FM signals are wide band and channelized so you don't really notice a pitch difference. You'll either get the signal or you wont. If you listen to a linear satellite that uses single sideband modulation instead of FM, with a linear VFO, you can definitely hear the doppler effect alter the pitch.
@@Skullfocher that's very interesting and intriguing! By VFO do you mean "Voltage Frequency Oscillator" ?
