Doug Leber provided the following report on the recent Las Animas High School Visit to the DSES site:
The Deep Space Exploration Society (DSES) hosted its first high school field trip on Wednesday, January 22, 2025, when seventeen Las Animas High School students and three staff members toured the Plishner Radio Astronomy and Space Sciences Center outside Haswell, CO. About half the students will participate in this year’s Colorado Science Olympiad competition. Jennifer Pointon, Science Olympiad coach, and Las Animas High School counselor, said she wanted students to see the Plishner facilities and learn how DSES can provide opportunities for research and mentorship in astronomy, radio, electronics, and engineering. Joshua Japhet (Las Animas HS Dean of Students and Science teacher) and Cody Hines (Las Animas HS Instructional Coach) also helped make this visit successful.
Bill Miller, DSES Vice President, gave an overview of the organization’s history and the years of effort required to revive the 60-foot-diameter radio telescope at the Haswell site. He introduced radio astronomy and some of the studies DSES members have conducted since restoring the telescope, including detecting pulsars and masers, observing solar and planetary radio emissions, and mapping the hydrogen line to show which galaxies are moving toward or away from Earth.
DSES Board member Ray Uberecken and DSES member Roger Oakey showed students how we control the dish to track and focus on deep space objects as Earth revolves. Mr. Japhet said students enjoyed watching how the huge dish moved. Mr. Uberecken also showed different ways radio frequency signals are represented, using an oscilloscope to show a signal’s waveform in real-time (the frequency and shape of an electrical signal) and the same signal in a waterfall display, which shows its intensity and relationship to other signals nearby on the radio spectrum.
Students then braved the intense winds and cold to venture to the bunker location of the DSES amateur radio station, where Board member Paul Sobon demonstrated how long-distance contacts are made using high-frequency (HF) transceivers. Under his supervision, several students learned to call ‘CQ,’ the amateur radio shorthand for “I’m here and ready to take your call!” Unfortunately, because band conditions were poor, no student got a response. Later, Paul Sobon reached a radio amateur in the Canary Islands, and students observed two-way HF radio communication between stations over 5,000 miles apart.
Since 2009, society members have devoted hundreds of hours to rebuilding the Plishner site. In 2023, a grant from Amateur Radio Digital Communications (ARDC) provided funds to complete a new building suitable for hosting groups.
DSES President Myron Babcock noted that this field trip visit to the Plishner Radio Astronomy and Space Sciences Center reflected the dreams of Michael Lowe, former Board DSES Board President, who sought to create a center for radio astronomy and space science education in Southeast Colorado. Over the next year, DSES hopes to host more school trips to the Plishner Center and work with area middle- and high-school students to advance their studies in science and radio.
If you are a parent, teacher, or school representative interested in learning more about DSES and how the society can support your students, please contact Doug Leber, the DSES education outreach coordinator.
Bill Miller KC0FHN DSES VP has compiled a detailed list of all the major DSES activities for 2024. It’s an amazing set of accomplishments that the society can be proud of.
The Deep Space Exploration Society participated in the 2024 ARRL EME contest using the K0PRT station operating on 23 cm (1296 MHz). This was the first major contest that was held at the new building, and it was a very successful operation with over 20 participants across the two weekends. Paul NO0T coordinated the activity with several out-of-town visitors in attendance.
The first weekend, October 19-20, was impacted by a severe storm that came through Haswell on Friday night and prevented operations for the first day. After the storm it was discovered that there was a failure in the dish movement mechanism. After climbing inside the pedestal, a broken chain was found on the azimuth drive. After two trips to the Eads NAPA auto parts store a replacement chain was put into operation. This allowed the station to participate in the contest on the second day.
The second weekend, November 16-17, had very good attendance with some local visitors, good food, and folks sleeping over in the new building. The heating, kitchen and restroom in the new building worked out great for those that attended. Thanks to Bill KC0FHN for insuring that the new building was operational. In addition to the operators on site, there was also a remote operation by Mark VK6PY. Mike K0FYR shot a great video covering the second weekend of the contest: ARRL EME 2024.
Alex K6VHF provided a detailed breakdown of the contacts made during the contest: Contest Results. Highlights include 163 contacts, of which 9 were CW, the rest were Q65 Digital. There were 31 countries worked, across 5 contents and 18 zones. This included an amazing contact with Martin PJ4MM in Bonaire who was running 10 watts into a 63-element antenna. We were the first US station to work him. See the photo below that shows an in-person exchange of QSL cards at Alex’s house.
Over 50% of the contacts were to Europe. With a score of 1,536,800 points, we likely finished in the top 5 worldwide. If we had been able to operate on the first night in October, we would have done even better!
Equipment used include the DSES 60-foot dish, Icom 705 and “Dianne” – a 1296 MHz transverter with 300 watts of power. Various software programs include WSJT-X, Win4Icom, N1MM+, Splashtop (for remote access) and the DSES custom built antenna tracking software.
Thanks to everyone who participated and cleaned up after the event.
Bill Miller, DSES VP, has written a great report on the DSES Open House that was held on October 5, 2024. It was a very successful event with over 100 attendees enjoying the new building and other activities.
The first DSES SSTV EME Party was held on Saturday September 28, 2024. Successful image transmissions were made to several EME stations in Europe and the United States. See the report including screen shots of received images.
The activity was conducted from the new DSES operations building at our Haswell Colorado site. Here is what the Dish operations console looked like during the event:
NRAO’s Ham Radio-Related Online Courses are Open for Enrollment.
National Radio Astronomy Observatory (NRAO)Funded by a grant from ARDC, the National Radio Astronomy Observatory (NRAO) has developed two no-cost, self-paced online courses on the SuperKnova platform that introduce amateur radio-related fundamental concepts. These courses were created in an effort to not only get learners licensed, but to also grow the amateur radio community, contributing to the hobby’s longevity.
If you’re interested in becoming a ham, if you’re already a ham and need a refresher, or if you’re simply interested in the fundamentals of the electromagnetic spectrum as it applies to your career, check out the below links to enroll in one of these courses:
As mentioned at the recent EME Conference in NJ, K0PRT will be having the first Fall SSTV EME QSO Party on Saturday September 28th on 23cm. K0PRT will be in operation with the 60 foot dish and about 350 watts. Moonrise in Colorado will be at 3:00 AM (09:00 UTC) so we will be up very early to work EU. Moonset for us is 5:30PM or 23:30 UTC. We encourage as many stations as possible to get on SSTV that day. We will be using YONIQ Improved SSTV software – for those new to SSTV, YONIQ is not a new program, but a continuation and an update of the wonderful work done by JE3HHT called MMSSTV. So, it’s simply a version of the original software, which shares its GNU license as is the desire of its legitimate creator Makoto Mori.
The latest version of YONIQ is 1.13.3 and can be downloaded from YONIQ v1.13.3 (Thanks to Grupo Radio Galena). There is an English language UI version option in the software dropdowns.
Stations that hear K0PRT – please send us the pictures that you copy (also, if you can capture the audio file, please send that as well) to Paul Sobon sobonpaul(at)gmail.com. We will post as many of these pictures received as we can on the DSES web site.
We will be coordinating on HB9Q Logger. Suggested frequencies between 1296.120 – 1296.140
The Deep Space Exploration Society (DSES), a 501 C(3) non-profit (K0PRT) is working to save a 30-foot EME dish which was built and used by Bruce K0YW who passed away last year. The 30-foot Kennedy EME dish is located in a remote area of SW Colorado near Ignacio and is scheduled to be torn down for metal scrap this July so that the property can be sold by Bruce’s XYL.
DSES is trying to raise donations to help pay for a crane and then transport the antenna 330 miles to their location near Haswell Colorado in SE Colorado and reinstall the dish. All donations received will help fund this dish removal, which includes crane rental, transportation, lodging and any associated cost in the reassembly process and re-mounting this dish back on the 25-foot tower secured to a large concrete foundation at the DSES Plishner Site in Southeast Colorado.
No amount is too small and DSES really appreciates your support. The plan is to rebuild and reinstall the dish late this year or early in 2025.
