Great Technical References from N1UL, Dr. Ulrich Rohde

By qrznow

” There are a few famous hams in our ranks and this week I had the pleasure of speaking with Dr. Ulrich Rohde, one of the founders of Rohde & Swartz, one of the world’s foremost test and measurement equipment companies. Dr. Rohde was one of the pioneers of SDR and quoted from the DL35SDR page:

Prof. Dr.-Ing. habil. Ulrich L. Rohde, DJ2LR / N1UL was the first to describe possibilities and perspectives of SDR in a congress lecture at the “Third International Conference on HF Communication Systems and Techniques” in London in February 1985 (classified).

DJ2LR / N1UL, member of DARC Amateur Radio Club Munich South (C18) is recognized as one of the pioneers of SDR technology 35 years ago. In the 1970s DJ2LR was head of military equipment development at AEG/Telefunken in Ulm, where he was responsible for the construction of the AEG 6861 Manpack.​

We’re excited to have received three excellent technical papers from Dr. Rohde, which he enthusiastically for wide distribution on QRZ. We’re honored to have him as a QRZ member and proud to serve these pages in support of his longtime service to all.

There are three papers. They are all in PDF format, attached to this article. They include:

  • Test and Measurement for Radio Communication Equipment
  • The Rebirth of HF
  • Using small antenna for portable operations

We hope you enjoy these great references from Dr. Rohde.

AMSAT-DL Submits Lunar Lander Proposal to European Space Agency

By qrznow

Germany’s amateur satellite organization AMSAT-DL has submitted a comprehensive proposal to the European Space Agency (ESA) for its Lunar Amateur Radio Transponder (LunART) lunar lander — a communications platform on the Large European Lander to support communication and payload experiments. AMSAT-DL’s Peter Gülzow, DB2OS, and Matthias Bopp, DD1US, say that a LunART (called “LunaART” in the AMSAT-DL proposal) would support direct communication with Earth via amateur radio, support university and student payloads and offer direct access to their experiments, and expand the reach of radio science. It could also provide backup communication capability and capacity during an emergency, or when the ESA network is busy.

The comprehensive radio platform would use the European frequency protocol of 2.4 GHz up and 10.45 GHz down (approximately 100 W), pioneered in the QO-100 satellite, the first geosynchronous amateur radio payload. The platform would also include a VHF/UHF transponder. AMSAT-DL would develop and build the necessary hardware and software and provide ground station support via the 20-meter dish at AMSAT-DL headquarters in Bochum, Germany. They envision developing a smaller ground station with an approximately 1-meter dish to support groups, including schools and universities. Low-power beacons would transmit on various frequencies from VHF (145 MHz) through SHF (up to 24 GHz or even 47 GHz), AMSAT-DL’s proposal says.

“This transponder would also be an ideal platform to develop new transmission schemes with novel modulation and coding techniques optimized for long-distance communications with the corresponding high latency (long delays),” AMSAT-DL said. “This would provide essential knowledge in preparation of a future Mars mission.” In addition, LunART could include the capability to transmit still or slow-scan television images and video to schools “from cameras attached to the lander monitoring the moon surface and perhaps the Earth in the background [which] would be ideal stimuli for getting school kids and STEM organizations further interested in space.”

The proposal is on open access at the ESA website and is now being evaluated. AMSAT-DL’s LunART follows the Lunar Amateur Radio Interaction Experiment (LARIE) proposal from Andy Thomas, G0SFJ. Both refer to weak signal modes and suggest the same frequency bands. Thomas said he welcomes LunART as a well-developed proposal and hopes ESA will support it as well. — Thanks to Southgate Amateur Radio News, AMSAT-DL, and ESA

The Uncertain Future of Ham Radio

By qrznow

By Julianne Pepitone

Software-defined radio and cheap hardware are shaking up a hobby long associated with


Will the amateur airwaves fall silent? Since the dawn of radio, amateur operators—hams—have transmitted on tenaciously guarded slices of spectrum. Electronic engineering has benefited tremendously from their activity, from the level of the individual engineer to the entire field. But the rise of the Internet in the 1990s, with its ability to easily connect billions of people, captured the attention of many potential hams. Now, with time taking its toll on the ranks of operators, new technologies offer opportunities to revitalize amateur radio, even if in a form that previous generations might not recognize.

The number of U.S. amateur licenses has held at an anemic 1 percent annual growth for the past few years, with about 7,000 new licensees added every year for a total of 755,430 in 2018. The U.S. Federal Communications Commission doesn’t track demographic data of operators, but anecdotally, white men in their 60s and 70s make up much of the population. As these baby boomers age out, the fear is that there are too few young people to sustain the hobby.

“It’s the $60,000 question: How do we get the kids involved?” says Howard Michel, former CEO of the American Radio Relay League (ARRL). (Since speaking with IEEE Spectrum, Michel has left the ARRL. A permanent replacement has not yet been appointed.)

This question of how to attract younger operators also reveals deep divides in the ham community about the future of amateur radio. Like any large population, ham enthusiasts are no monolith; their opinions and outlooks on the decades to come vary widely. And emerging digital technologies are exacerbating these divides: Some hams see them as the future of amateur radio, while others grouse that they are eviscerating some of the best things about it……READ FULL ARTICLE

AMSAT Leadership Explains 2018-2020 Legal Expenses

On July 10, 2020, AMSAT President Clayton Coleman, W5PFG, sent the following letter to AMSAT members regarding legal expenses incurred during the 2018-2020 timeframe. The letter was co-signed by Dr. Tom Clark, K3IO, Martha Saragovitz, Keith Baker, KB1SF, Robert Bankston, CPA, KE4AL, Jerry Buxton, N0JY, Drew Glasbrenner, KO4MA, Dr. Mark Hammond, N8MH, Bruce Paige, KK5DO, and Paul Stoetzer, N8HM.

[ANS thanks the AMSAT Office for the above information]

Update on HO-107 (HuskySat-1)

AMSAT Vice President – Engineering Jerry Buxton, N0JY, posted the following update on HO-107 (HuskySat-1) on the AMSAT-BB:

While it is disappointing that the transponder did not see a longer period of use following the science missions, the overall HuskySat-1/HO-107 project and mission were quite beneficial for our
partner and for AMSAT. The HuskySat-1 team were able to command their satellite and experiments and receive the telemetry they sought, and AMSAT was able to work through the extensive process of making a new design for a “black box” radio module that can be integrated into a non-AMSAT spacecraft and fly in the space environment.

The LTM (Linear Transponder Module) on HO-107 worked for over three months after HuskySat-1 came alive following its deployment. The failure of the LTM came during or just after a period of full sun where LTM temperatures reached over 80 degrees Celsius.

While licensed and operated as an amateur radio satellite by AMSAT during the transponder use, there are some facts that set HO-107 apart from our Fox-1 CubeSats and other AMSAT satellites.

1. It’s not our satellite. We have no control and may not have any insight into how a partner actually uses the LTM. While we see the LTM temperatures and many of the other typical data fields that we downlink to FoxTelem regarding LTM health, data such as temperature of the host environment as well as other specific information like power and the state of the other systems in a host satellite may or may not be available to us. Whether LTM is operated within design limits is entirely up to the host.

The University of Washington HuskySat Labs team was very cooperative with us on this mission, however there are things regarding their mission that we do not know because they are processing and studying their data for use in their thesis and classes and preparing it for release in a specific way typical of such an institution today. AMSAT is generally more forthcoming with information about our missions but what we can and have said about this mission is determined by UW. That is really no different to certain aspects of our own missions. Most members are likely familiar with the vague wording I provide for some of our launch timelines and that is the result of the same thing, in the owner of the launch vehicle or LSP/APIC determining what we can say to the public and when.

2. HO-107 was the first ever use of a new product, the AMSAT LTM. The LTM idea was first put forth at the AMSAT leadership strategic planning meeting in 2017 and is now coming into availability for other non-AMSAT CubeSats to fly amateur radio on their mission.

HO-107 is the pilot production of LTM and was developed in partnership with UW HuskySat-1. It was the first CubeSat radio module designed and built by AMSAT for use in other host CubeSats, and UW was key in working with us through the design and processes needed to provide such a module. They did not buy it as, nor did we give it to them as an “off the shelf” product as we plan to for future LTM production. LTM was developed from the Fox-1E linear transponder design, and provided in a partnership with UW that started in November 2014 when we made an agreement with University of Washington to fly an amateur radio on their CubeSat mission. Overall, the HuskySat-1 team were quite happy with the telemetry and command performance even with the LTM anomalies showing up toward the end of their experiments. In the process of getting HuskySat-1 to orbit several students became interested in amateur radio, and we have already had preliminary
discussions of future joint mission plans.

The ability to provide more LTM to new and future partners will increase the number of orbiting satellites carrying amateur radio, at a low cost to AMSAT and the partner, keeping amateur radio in space even as we develop newer and more capable satellites. There is no doubt that HO-107 was a success in many ways beyond the operational life of the transponder.

As usual, the AMSAT Engineering team of volunteers deserve the praise for putting yet another amateur radio in space be it in our own satellite, or in a partner satellite!

AMSAT-DL Proposes LunART – Luna Amateur Radio Transponder

AMSAT-DL has submitted a proposal to the European Space Agency to place an amateur radio communications link on the Large European Lander. This system would support direct communication with earth through amateur radio frequencies in the microwave bands, support University and Student Payloads with direct access to their experiments, allow Radio Science for a huge community of radio amateur operators and scientists worldwide. It would also provide an important back-up communication capability and capacity during emergency or when the ESA network is busy.

More details can be found at

AMSAT wishes our friends at AMSAT-DL the best of luck on their proposal. This would be a great resource for amateur radio should it come to fruition.
