You Can Talk to the ISS With Nothing But a Ham Radio

You’ve just got to time it right.

Adrian Lane of Gloucestershire, England, got in touch with the International Space Station the other day. Thanks to impeccable timing and a prime location under the ISS’s path above the Earth, Lane was able to have a brief conversation with space station’s crew via ham radio. It must be surreal to have a casual chat with humans who are floating up there in the void, but technologically, it’s really not even that hard….

This article is a fun read about a man in the U.K. who made a chance contact with an astronaut on the ISS. We are considering working local schools as we did with our HAB project to see if we can secure an ISS contact for a group of local students. If you are interested in working with us on this project, please contact me at via email at [email protected].

Sights From Field Day 2017

Field Day 2017 is but a memory for us now. Dave, K1DLM, our Field Day Chairman, and the entire Field Day team did a great job with putting together our Field Day operation this year.

We are still adding up our score and collecting pictures and video from everyone. I wanted to get something out quickly so that we could begin to enjoy some of the memories. So here is my quick Sights from Field Day 2017….

and our new 60 ft. tower was a sight to behold!

Field Day 2017 - 40M SSB Station
40M SSB Station

We built lots of stations – 3 SSB, 3 CW, a RTTY/PSK Digital Station, a GOTA station, a 6M Station with a new yagi, and a computer controller Satellite Station. We also setup a 2M/70cm Go Kit for talk-in and APRS demos. All totaled, we had 10 transmitters on the air! Our exchange was 7A NH.

We got our Solar-Battery bonus late on Saturday.

CW Ops – Dennis, K1LGQ

Our CW operators were amazing again this year. Here’s Dennis banging out CW QSOs. Dave, KM3T even operated SO2R for a period – calling “CQ” and working contacts on both 20M and 40M CW at the same time! Gene, W3UA brought his CW skimmer and we set up an OCF dipole to provide on-site CW spots.

Team Finchum was in high gear as always – here’s Abby, AB1BY operating with her brother Connor, KC1GGX. It seemed like Abby was on every SSB station that I looked at all weekend long…

New Digital Station For Field Day 2017
New Digital Station For 2017

Our new SDR powered Digital Station worked well and we had lots of digital contacts using the antennas on the new 60 ft. tower.

Field Day 2017 SDR GOTA Was Cool!
The SDR GOTA Was Cool!

The SDR-based GOTA station worked out super well. Ira, KC1EMJ was our GOTA coach and was busy on Saturday and Sunday introducing our guests and newly licensed members to “high-tech” Amateur Radio. We had many young people try Amateur Radio for the very first time on our GOTA station.

Field Day 2017 Remote SDR System
Remote SDR System

We operated the two SDRs for the Digital and GOTA stations remotely over a coax cable data link between the upper and lower fields. Pierce, K1FOP and Dave, K1DLM put together this high-tech setup and the underpinning data networking system.

John, W1SMN, and Desmond, WK1V Operating SSB

Did I mention that we operated hard making lots of QSOs?…

Field Day 2017 Drone Sighting

There were Drone sighting all weekend long…

and Desmond, WK1V got some amazing video from the air.

It was a lot of fun operating as N1FD, 7A NH!

Anita, AB1QB, our scoring chairman is still working on tallying up our score but it will be higher than last year.

Please take a minute and send me any photos or video that you have from Field Day 2017. We’ll be producing a video of all of the fun for the Field Day 2017 Recap at our club meeting on July 11th. Don’t miss it!

High-Altitude Balloon Project Update #3 – Launch!

Our High-Altitude Balloon made it to the edge of space! The image above was taken from our HAB at an altitude of over 90,000 ft!

After many months of work, raising funds to finance the project, teaching STEM sessions in local High Schools, and an open-house to test the Balloon Platform and to learn about Amateur Radio; our High-Altitude Balloon Project (HAB) Team finally got the chance to launch and track our Balloon. We launched our Balloon from the Elementary School in Winchester, NH.

Setting Up Our Gear On Site

Students, Teachers and Club Members came out to be part of the launch and to track our HAB. The first step was to move all of our gear to the center of the athletic fields at the school and organize all of our equipment.

Next, we attached the GoPro video cameras, satellite tracker and the battery pack for the Flight Computer and 2M APRS transmitter to the flight platform. We used an APRS capable HT to confirm that the flight computer and APRS transmitter were working.

We rigged the 40 ft. flight line which connected the HAB’s flight platform, recovery parachute, and the balloon.

High-Altitude Balloon Inflation

And then came the inflation of the balloon from the Helium tank. The winds were gusting to about 12 mph at this point which made inflating the balloon a little tricky. When filled, the balloon was about 6 ft. in diameter on the ground.

High-Altitude Balloon Launch!

With both GoPro cameras running on the flight platform, we were ready to launch. A 10-second countdown and the balloon was up and away!

Tracking Our High-Altitude Balloon
Tracking the HAB

We watched the balloon from the ground as it soared off into the clouds. The 2M APRS tracking system worked perfectly and we spent the next several hours at the launch site, at lunch, and in our cars tracking the HAB on aprs.fi.

Our HAB’s flight path took it across Massachusetts where it reached a maximum altitude of 91,700 ft. above sea level (ASL).

The balloon reached a diameter of approximately 30 ft before it burst. After the balloon burst, the parachute deployed and the payload descended to a landing in the northeast corner of Rhode Island.

A combination of the APRS transmitter data and the onboard sounder allowed the landing location to be pinpointed and the flight platform recovered with help from a local resident.

The onboard GoPro video cameras captured some awesome video during our HAB’s ascent! All of the media captured by everyone who participated in the launch as well as the APRS data allowed us to produce the video above. Turn up your speakers and give it a play in full-screen mode to enjoy the experience what we shared!

By the time we had launched, the school year was at an end so we will have to wait until the fall to work with the students and teachers who were part of our STEM project to analyze the data from the flight. All in all, our HAB project has been an amazing experience for all involved. We are planning another HAB STEM experience and launch with additional schools in the fall.

We want to especially thank all of our donors whose generous contributions made this project possible.
