RADIO ASTRONOMY & SATELLITES - The 2026 season continues until the HamX convention in August.  See schedule below. 

This was a new workshop developed and taught by Worcester PolyTech (WPI) student Rye Hogan and several staff from NESciTech.  

From September 2026 through June 2027, this workshop will be taught in small, 3-week modules. Students will be able to sign up for topics of interest, skip over some weeks, and rejoin for later sessions. Keep an eye on the weekly Newsletter for updates.

A specialized activity for students who are members of NEST, we offer a hands-on introduction to digital radio, satellite communication and radio astronomy. Using Software Defined Radio (SDR), you'll explore the RF spectrum, and capture real signals from aircraft, satellites, and the galaxy. We'll start with the fundamentals, but go on to explore the deeper relationships between these topics.

In the various 3-week modules, you'll design and build working antennas (a dipole, helical, and horn antenna), use them to track airplanes in real time, receive images and data from space, and capture the 21cm hydrogen line emitted by our galaxy. You'll learn how scientists and engineers use radio waves every day for exploration and communication. If you've ever wanted an introduction to the world of digital radio, antenna design, satellite communication, or radio astronomy, these workshops will be a great place to start.
 
After the workshops end, students will be encouraged to evaluate their data and give a report at a radio conference in Marlborough in August. Students will be expected to achieve an FCC Amateur Radio License (beginner level) during this program.

These workshops are limited to 10 students. Students will be expected to work with others in teams. 

2026-27 SESSIONS 

Radio Astronomy & Satellites
Registration will open in May. 
(Must maintain membership for program duration)

ALSO: Student Permissions Form

Meetings are Saturdays, 9:30-11:30 AM from mid-SEPT to mid-JUNE.

Parents are encouraged to join their students in workshops.

We ask that students as a team present their projects and findings at the HamXposition in August.

Using a homemade antenna and a digitizer dongle, Jonathan demonstrates how Software Defined Radio (SDR) works. He is downloading image data directly from a weather satellite over New England.


New England Sci-Tech is grateful to ARDC for a grant that allows us to offer this workshop for almost no cost to students, to purchase the hardware that students can build and keep, and to pay for the students' admissions and meals at the Amateur Radio Convention in August.

ADDITIONAL INFORMATION

These dates are subject to change. On alternate and holiday weekend dates when the workshop does not meet, students are welcome to attend other clubs, such as rocketry, robotics, or battlin' bots, or to continue working on projects.

 

Because of traffic conditions and for your convenience, you are welcome to drop off and pick up for up to 30 minutes on each side of class time. Members may stay through the day during member open time.

 

If a class cannot meet in person because of severe weather, we may switch to online classes via Zoom.

 

*NOTE: Students must be a current member of New England Sci-Tech as a "Teen" or "Family" membership level. Having a club membership alone (radio or rocketry club) or supporting membership does not qualify a student for general NEST activities and programs like this.  Membership must run from at least November through April for class participation.

Please be aware of our Cancellation and Refund Policies. For questions, e-mail info@nescitech.org or call 508-720-4179.


In addition to registering for this workshop, please fill out the Workshop Student Permissions Form.
