Our HAB at the Edge of Space (GoPro Capture)

Our HAB at the Edge of Space (GoPro Capture)

We 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 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

Setting Up Our Gear

Students, Teachers, and Club Members came out to participate in the launch and 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.

Assembled Flight Platform

Assembled Flight Platform

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

Rigging the Flight Line

Rigging the Flight Line

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

Balloon Inflation

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

Launch!

Launch!

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

Tracking the HAB

Tracking the HAB

We watched the balloon from the ground soaring 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 the media captured by everyone who participated in the launch and the APRS data allowed us to produce the video above. Turn up your speakers and give them a play in full-screen mode to enjoy the experience that we shared!

By the time we had launched, the school 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.

Members of the Nashua Area Radio Club launched a High-Altitude Balloon (HAB) to the edge of space and back this past weekend. Our HAB carried a 2m APRS Transmitter and sent position and atmospheric telemetry to the ground during its flight. Our HAB was tracked by many folks using aprsi.fi during its flight via the N1FD-11 call sign.

You can see an amazing video of the flight, including footage taken during our launch and from the balloon while in flight above.

Our HAB launch was part of a STEM learning project that our club did in partnership with several High Schools in New Hampshire. You can read more about the project and our STEM work on our club’s Blog here.

Enjoy!

High Altitude Balloon At The Edge Of Space

STEM Learning via a High Altitude Balloon At The Edge Of Space

As some of you may already know, Anita and I have been working with our local Radio Club on a project to promote STEM learning and interest in Amateur Radio among young people in our area. The idea is to work with kids grades 7-12 to plan, build, launch and recover a High-Altitude Balloon carrying Amateur Radio. Our balloon should be able to reach an altitude of about 100,000 ft before it bursts and the payload returns to earth via a parachute system. The payload will include a computer, GPS, and a 2-meter APRS transmitter to record the balloon’s flight track, atmospheric data, and altitude throughout the flight. The balloon will also carry a video camera and will capture a video recording of the entire flight. You can learn more about our project here.

Project Team Members Will Analyze and Report On Scientific Data

Project Team Members Will Analyze and Report On Scientific Data

We are working with local schools to put together a team of young people to plan and execute our project. This will include designing the onboard science experiments, analyzing the data collected, and providing a presentation about what was learned to fellow students and others.

You can learn more about our project and view a video that shows what our balloon flight will be like on our Club website. This project is part of our Club’s ongoing program to promote interest in Amateur Radio among young people. The folks at HAMNation recently featured a video that included some information about our club’s activities for young people.

We are working to raise the necessary funds to enable the project to be completed during the current school year. We have set up a GoFundMe page to facilitate the fundraising aspect of our project. We know that we have many readers around the world who follow our blog and it would be wonderful if some of our readers could help us by contributing to funding our project.

Anita and I will continue to post information about our project here.

Best and 73,

2015 Dayton, OH County Tour

Planning a County Hunter’s Tour – 2015 Dayton, OH County Route

Anita (AB1QB) and I have been having a lot of fun with our Mobile HF station since we completed it several months back. We’ve been working quite a bit of DX, and we make contacts whenever we are doing errands or taking other trips. We are planning to attend the Hamvention in Dayton, OH again this year, and Anita suggested that we use the trip to activate some most wanted United States Counties along the way.

CQ US-CA Award

CQ US-CA Award

U.S. County Hunters are Amateur Radio operators seeking to work and confirm all 3,077 U.S. Counties. CQ Magazine has an awards program for U.S. County Hunters. Quite a few Amateur Radio operators work all U.S. Counties – some do this using multiple modes, and several have done it multiple times. To find out more about the US-CA Award, see the excellent County Hunter Dot Com site.

The Mobile Amateur Radio Awards Club (MARAC) is a support group for county hunting and mobile activities with members worldwide. This is a great organization to join if you are interested in County Hunting. MARAC provides additional awards center around County Hunting and mobile operating.

You can also view WY7LL’s video on YouTube for a nice introduction to County Hunting, MARAC, and the tools the group provides to help County Hunters.

Anita did the planning for our County Tour to Dayton, OH, and back. She began by looking at the County Hunter’s Web most wanted page to determine which counties lie along potential routes between our home and Dayton, OH were most needed by County Hunters. Based upon this information, she created the route shown at the beginning of this post. As you can see, we are taking different routes going to Dayton, OH and back to allow us to activate as many U.S. Counties as we can. We are also taking a few side trips off our route to activate a few of the most needed Counties near our route.

Planned U.S. County Activation Schedule

The table above shows the 86 U.S. Counties that we plan to activate on our trip along with a rough idea of our schedule.

County Finder App

County Finder App

We found a useful iPhone App (County Finder) that will tell us what County we are in at a given time. The County Finder App uses the GPS in our iPhones to provide our current location in real-time.

Ham Clock Grid Square App

HamClock Grid Square App

We will also be tracking and logging the current grid square that we are operating from. We will be using the HamClock App on our iPhones to determine our grid square of operation in real-time.

Mobile Logging

Mobile Logging

Anita and I will be taking turns operating and logging. We are planning to use a laptop computer running the DXLab Suite, and we will connect it directly to the IC-7000 Radio in our truck. This combination, plus the County Finder and HamClock Apps above, should allow us to log all of our contacts accurately. We will also be uploading contracts that we make to eQSL, LoTW, and ClubLog in real-time as we operate.

OpenAPRS App

OpenAPRS App

We will also be running an APRS station so that folks can see where we are located in real-time and follow our progress. We are using the OpenAPRS iPhone App for this purpose. Our APRS callsign with be AB1QB-15, and you can see our position and progress on aprs.fi at any time by clicking here.

N1FD Special Event QSL Card

N1FD – Nashua Area Radio Club QSL

Anita and I are the Nashua Area Radio Club members, and we will be operating using the Club’s call sign, N1FD/M, during the trip. In addition to the electronic QSL’ing methods mentioned above, we will also be able to provide paper QSLs using the Club’s QSL card shown above. All paper QSLs we send will note the correct County and Grid Square from which the QSL’ed contact was made. See N1FD on QRZ.com for QSL information.

Band County Hunters Net Frequency (SSB)
20m 14.336 & 14.271 MHz
40m 7.188 MHz
80m 3.901 MHz
17m 18.136 MHz
15m 21.336 MHz
12m 24.936 MHz
10m 28.336 MHz

County Hunters Net Frequencies

We plan to operate on or near the County Hunters Net Frequencies listed above. We will be QRV SSB on all of these bands, and we may also do a limited amount of operating on 160m SSB as well.

Scorpion SA-680 Screwdriver Antenna

Our Mobile HF Station

We hope you will take some time to work us during our trip. If you do and you read our Blog, please let us know. If we do not have other stations calling, we’d like to take a little time to say “hello” and get to know some of our readers better. We will also be attending the County Hunter’s Forum on Friday, May 15th, at this year’s Dayton Hamvention. If you are there, please introduce yourself, and we’ll have an “eyeball QSO”.
