May 2024 Meeting

For May 2024 we had Dr Paul Wilkinson, K6IG, present on “Ham Radio Use of Arduino and Raspberry Pi.” Dr Paul enlightened us on how to put these devices to work for our hobby.

We also learned that a Raspberry Pi has more computing power than the supercomputers of the 70s and 80s. Thank you Dr Paul for an informative and entertaining briefing.

Dr Paul’s presentation can be downloaded here (Google) and here (Apple).

“In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1.” Reference:

Dear DSES Members,

We are thrilled to announce that, once again, the Deep Space Exploration Society (DSES) has been invited to participate in the 2024 European Earth-Moon-Earth (EME) Contest sponsored by DUBUS and REF, set to commence on May 10 at 0000 UTC. This prestigious European contest, focusing on Continuous Wave (CW)/Single Side Band (SSB) communication, presents an exciting opportunity for our members to engage in Earth-Moon-Earth (EME) communication with the international community.
Date Begin:    Friday, May 10, 2024, at 6 PM MSTDate End:       Sunday, May 12, 2024, at 1 PM MSTLocation:       Paul Plishner Radio Astronomy and Space Sciences Center

                       9301 County Rd 20, Haswell CO 81045

Last year, our participation in the contest yielded remarkable results, with our members successfully contacting over 80 stations off the moon using our formidable 60-foot dish. In fact, our collective efforts secured us a remarkable 2nd place in this esteemed worldwide contest. Building upon this success, our goal this year is to surpass the number of contacts made and demonstrate our ongoing commitment to excellence in deep-space communication.

It’s important to note that the contest primarily occurs during daytime hours, aligning with the moon’s morning rise and facilitating communication with many European stations. Additionally, we anticipate Pacific and Asian EME contacts during the late afternoon and early evening hours. Moonset times are scheduled for 10:20 PM MST on Friday and 11:20 PM MST on Saturday evening, providing ample opportunities for engagement.

For those planning to join us, rustic overnight accommodation will be available in the new unfinished building. Please remember to bring your own sleeping bags and cot/air mattress. Alternatively, the Cobblestone Inn in Eads, CO, is available for those seeking more comfortable lodging. Reservations are necessary for accommodation at either location.

To facilitate our planning efforts, we kindly request interested participants to contact:Vice President Marketing Paul Sobon, NOØT

Also on Wednesday May 8, 2024 at 6:30 PM there will be a Contest Zoom call to confirm operators, times, operating preferences, guests attending, those with their own headphones and/or keyer paddles, refreshments and snacks, campers, RV’s. The Zoom will be open at 6:00 PM for those wishing to adjust their cameras etc.  Here is the Zoom information:

Hotspots and Digital Modes

Scott Broadribb, KD7NMO, briefed on January 8th at Fargo’s Pizza, attracting the biggest crowd we’ve had in 3 years. Scott peaked our interest in cutting-edge ham-radio technologies with which most of us haven’t yet experimented. But we will now, knowing the cost of entry is low and the capabilities are high.

Stay tuned to this website! If you missed the presentation, Tom Bonifas, KCØYVW, recorded it and we will post it here soon.

Nuclear Research and EMP

Bob Sayers, W0OFA, presented during our monthly meeting on December 4th, 2023. Q&A discussion revealed that many amateur radio operators will be ready to provide emergency communications in the event of an EMP attack.

Thanks Bob for sharing the insights from your first-hand experiences testing the effects of nuclear explosions.
