Amateur Radio Operator Contacts Spacecraft

The headlines are sensational, although a bit exaggerated: “Ham Radio ‘hacks’ NASA Satellite”. While the phrase is eye-catching for social media, the truth is just as exciting. Amateur radio astronomer Scott Tilley, VE7TIL, has made contact with NASA’s STEREO-A spacecraft, which passed Earth for the first time in 17 years.
The STEREO-A (Solar TErrestrial RElations Observatory) spacecraft was launched on October 25, 2006, from Cape Canaveral, Florida, with its twin sister ship, STEREO-B. Both spacecraft were on a mission to circle behind the and send images back to Earth so scientists could make 3D models of solar activity. In 2014, STEREO-B failed and was not heard from again.
“I’m having fun with STEREO-A,” Tilley reported to “The spacecraft is close to Earth this summer, and I can now receive its signal using a small 26-inch dish in my backyard.”
Scott Tilley’s, VE7TIL, dish antenna for receiving NASA STEREO-A spacecraft.
Tilley began hearing rumors that other radio operators were picking up signals from STEREO-A on 8443.580 MHz. He decided to check it out. “The central carrier is very loud, almost 30 dB above the noise,” he said. “I also noticed data sidebands, which are unusual to see on such a distant object for my small antenna.”
Tilley was able to decode and demodulate STEREO-A’s signal using a special program written by Alan Antonie, F4LAU, known as SatDump, and now, he is monitoring almost all of STEREO-A’s science instruments, including its Extreme Ultraviolet Imager (EUVI), two coronagraphs (COR1 and COR2), the heliospheric imager (HI), and a solar radio burst receiver (S/WAVES).
STEREO-A’s closest approach to Earth was scheduled to occur on August 17, 2023.
Amateur radio operators who would like to monitor STEREO-A can check out Tilley’s technical blog for more information.

Changes to AMSAT-NA TLE Distribution for August 18, 2023
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at
This week there are no additions or deletions to the weekly AMSAT TLE distribution.

Comments on making general contacts
I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts.  First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk.  Also, one needs to be aware of their normal daily schedule.  I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts.  Hopefully this will help you better schedule your opportunities.
Typical daily schedule
Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours
The crew’s usual waking period is 0730 – 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They’re usually free most of the weekend, as well.
SSTV events are not that often.  So please check out for the latest information or watch for the ARISS announcements.
And don’t forget that the packet system is active.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.
ARISS Radio Status
Columbus Module radios:
IORS (Kenwood D710GA) – STATUS – Configured. Default mode is for cross band repeater (145.990 MHz up {PL 67} & 437.800 MHz down).

* Powering off for Russian EVA on Aug. 09.
* Capable of supporting USOS scheduled voice contacts, packet and voice repeater ops.
Service Module radios:

Upcoming Satellite Operations

TF/DL2GRC: Got an email from Nina stating that she & the family will be heading to Iceland with operations scheduled to begin on Friday (18th).
From Nina:
We will do a trip around the Island and hope to be active on MEO, LEO and GEO: family, equipment, satellites and weather permitting. Operations can be expected between August 18th to 30th.  Please keep in mind, it will be a family holiday and no DX-pedition.
Look out for TF/DL4BEN, TF/DL8SCU and TF/DL2GRC.
Stay tuned!

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.
AMSAT Ambassador Mitch Ahrenstorff, AD0HJ will be at the Northern Plains Regional Radio Council (NPRRC) Hamfest in Brewster, Minnesota on Saturday, August 26, 2023. You can expect to find him engaging in discussions about amateur radio satellite operations at the AMSAT table or presenting live satellite demonstrations just across the street at Brewster City Park. Targeted demonstration passes will be on linear satellite RS-44 at 1434Z (fixed uplink 145.945 MHz) and the TEVEL FM satellites between 1630Z and 1700Z. Visit for additional information about the NPRRC Hamfest.

“Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”
Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences.

Satellite Shorts From All Over

+ RS-44 has returned to service after a multi-day outage this past week. There is no definitive word on the cause of the outage.
+ Woody Hoburg, KB3HTZ, was active as NA1SS from the ISS, utilizing the FM repeater, on Monday, August 14th around 1900 UTC and Wednesday, August 16th around 2100 UTC (ANS thanks ARISS for the above information)
+ NASA released its updated Software Catalog for 2023-2024, containing more than 1,000 programs for mission analysis, disaster response, spacecraft testing, data analytics, and more. Access restrictions apply to some software that may be limited to use by U.S. citizens or for U.S. government purposes only. Review the catalog online at: (ANS thanks The Orbital Index and NASA for the above information)
+ NASA will provide live launch and docking coverage of the Roscosmos Progress 85 cargo spacecraft carrying about three tons of food, fuel, and supplies for the Expedition 69 crew aboard the International Space Station (ISS). The unpiloted spacecraft is scheduled to launch at 01:08 UTC on Wednesday, Aug. 23 on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. The Progress spacecraft will be placed into a two-day, 34-orbit journey to the station, leading to an automatic docking to the Zvezda module at 03:50 UTC Friday, Aug. 25. As always, amateur radio operation aboard the ISS is suspended during docking maneuvers. The spacecraft will remain at the orbiting laboratory for approximately six months, then undock for a destructive but safe re-entry into Earth’s atmosphere to dispose of trash loaded by the crew. (ANS thanks NASA for the above information)
+ India’s Chandrayan-3 moon lander completed another lunar-orbit reduction burn and entered a 100 km circular polar lunar orbit ahead of a landing attempt next week. It is projected that the Indian craft will land two days after Russia’s Luna-25 lander. (ANS thanks The Orbital Index for the above information)
