AMSAT at Dayton Hamvention – Call for Volunteers

(repeated from last week)

It’s less than eight weeks away when Amateur Radio’s biggest event of the year happens at the Greene County Fairgrounds in Xenia, Ohio. That’s right, May 19-20 is Hamvention time when over 30,000 of our closest friends get together to get a first hand look at the latest products and to catch up with friends from around the world.

With over 1,200 square feet of exhibit space, AMSAT is a major Hamvention exhibitor with displays from Engineering, Operations, Educational Relations, the AMSAT Store and much more. Last year in 2022, about 35 people assisted with the AMSAT booth.  It was the efforts of those volunteers that made the 2022 Dayton Hamvention a success for AMSAT. The interaction with AMSAT members, satellite operators, designers, and builders makes the whole experience a lot of fun.

Would you consider helping AMSAT at the Hamvention this year? Whether you’re available for only a couple of hours or if you can spend the entire weekend with us, your help would be greatly appreciated.

If you will be attending Hamvention and can help, please send an e-mail to Phil Smith, W1EME, AMSAT Hamvention Coordinator via w1eme [at] amsat [dot]org.

The Secrets of Rocket Design Revealed

Tory Bruno, CEO of ULA shares some of the little-known techniques and implications of rocket architectural design. The discussion is fascinating and a valuable set of observations for those who are not in the business. Why big rockets sometimes do less. Why little rockets sometimes cost more. And why every rocket has its very own, perfect mission.

There is no single, best rocket. Different rockets do different things. As it turns out, the design of a rocket flows directly from the mission the rocket is intended to do, and there are many different missions. Any given rocket is optimal for a specific orbit and payload. Its efficiency falls off as we move away from that perfect case.

The entire Blog is comprehensive and available at:

Austria Restricts 23cm Band Operation

Austria has become the latest country to impose restrictions on Amateur Radio operation in the 23 cm band (1240-1300 MHz) to protect to protect ground-based receivers for the Galileo RNSS satellite constellation.

Advice from Austria’s national amateur radio society ÖVSV cites changes to the legal conditions in the AFU area from 03/13/2023:
Annex 2 of the Amateur Radio Ordinance is omitted and is now regulated in the Frequency Use Ordinance Annex 4. This results in some changes in the frequency ranges and powers.
For the KW bands 80m, 40m, 20m, 17m, 15m, 12m and 10m, 1KW (High-Power) can now be approved for Class 1 FA after 1 year of trouble-free operation.
Thus, the power limitation of 7100-7200 kHz (previously only 200W) in the 40m band is eliminated and AFU has primary status.
30m band still only max. 200W if power level B or C approved (no change)
160m band from 1810-1850 kHz now max. 200W if power level B or C approved and AFU has primary status.
160m band from 1850-2000 kHz only max. 100W (now instead of 1950 kHz up to 2000 kHz)

2023-03-13 Austrian Regulations
The 6m band has been extended from 52-54MHz. (Limited until 31.12.2030, for research WRAN)
-from 50-52 MHz now max 200W if power level B or C approved and AFU has primary status.
-from 52-54MHz only max 100W.
On the 70cm band now also allowed as already on 2m high-power (up to 1KW), if power level B or C approved (but only EME and MS with Yagis from at least 15dBd gain)
The 23cm band was kept, but the performance was severely limited
-only 10W allowed (previously max. 200W were allowed)
-Repeaters with more than 16kHz bandwidth must cease operation by December 31, 2024.
On all higher FM bands (except 10 GHz, since only 40dbW EIRB) now also max. 200W (previously only 100W) allowed.
On 24GHz AFU has only secondary status

Please note the new conditions.

Changes to AMSAT-NA TLE Distribution for March 26, 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

The following satellites have decayed from orbit and have been removed from this week’s AMSAT-NA TLE distribution:

Satellite Shorts From All Over

+ Doug Papay, K8DP has continued to document the GreenCube IO-117 user lists by providing a very nice mapping page using the Google My Maps application. It is well worth a browse if you are considering using the satellite or are already involved. See: [ANS thanks the Doug Papay, K8DP for the above information]

+ After 15 years in space, NASA’s Aeronomy of Ice in the Mesosphere (AIM) mission has ended. NASA first noticed issues with AIM’s battery in 2019, but the probe was still sending a “significant amount of data” back to Earth. NASA says AIM has now become unresponsive. Launched in 2007, AIM studied noctilucent or night-shining clouds, which can last hundreds of years in the Earth’s upper atmosphere. It was only meant to operate up for two years, but it’s provided data for multiple groundbreaking studies, including a study that found methane emissions are causing night-shining clouds to form more frequently. (ANS thanks Engadget for the above information)

+ The world’s first 3D-printed rocket launched successfully on Wednesday, marking a step forward for the California company behind the innovative spacecraft, though it failed to reach orbit. Billed as less costly to produce and fly, the unmanned Terran 1 rocket launched from Cape Canaveral, Florida at 11:25 pm (0325 GMT Thursday) but suffered an “anomaly” during second-stage separation as it streamed towards low Earth orbit, according to a livestream broadcast by aerospace startup Relativity Space.

+NASA planning to spend up to $1 billion on space station deorbit module. WASHINGTON — NASA is projecting spending nearly $1 billion on a tug to deorbit the International Space Station at the end of the decade to provide redundancy for safely disposing of the station. NASA released additional details March 13 about its fiscal year 2024 budget proposal. An outline of the proposal, published by the White House March 9, requested $27.2 billion for the agency, a 7.1% increase from 2023 that roughly keeps pace with inflation. One of the biggest new initiatives in the budget is the ISS deorbit tug, which would be used to perform the final lowering of the station’s orbit to ensure it reenters over the South Pacific. NASA first indicated its plans for the tug in a request for information last August, but offered few specifics about the vehicle in the budget request.

+Is it possible that SpaceX has succeeded in making orbital launches boring? Increasingly, the answer to this question appears to be yes. On Friday the California-based company launched two Falcon 9 rockets within the span of just a little more than four hours. At 12:26 pm local time, a Falcon 9 rocket carried 52 of SpaceX’s Starlink satellites into low-Earth orbit from a launch pad at Vandenberg Space Force Base in California. A mere 4 hours and 12 minutes later, another Falcon 9 rocket delivered two large communications satellites into geostationary transfer orbit for the Luxembourg-based satellite company SES from Cape Canaveral, Florida. This broke SpaceX’s record for the shortest duration between two launches. However, the overall record for the lowest time between two launches of the same rocket still belongs to the Russian-built Soyuz vehicle. In June 2013, Roscosmos launched a Soyuz booster from Kazakhstan, and Arianespace launched a Soyuz from French Guiana within two hours. Those launches were conducted by two separate space agencies on separate continents, however. More may be found at [ANS thanks Eric Berger of ARS Technica for the above information]
