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.

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.

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.

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!

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.

SOTA/POTA and 6 Meters

I got really excited, when Jamey, KC1ENX set our Club’s first Summits On The Air (SOTA)/Parks On The Air (POTA) activation for the same day as the June VHF Contest! Jamey choose Pack Monadnock in Miller State Park here in New Hampshire as the site for our activation. With Jamey’s help, we put together a portable 6M SOTA station in preparation for the activation.

Portable 6M SOTA Station Equipment

The idea was to use an IC-7300 to create a 100W station and use a Solar/Battery combination to power the setup. Solar/Battery made us “legal” as a SOTA activation. We combined two 90W solar panels which I had with an MPPT solar charging system and two LiPo batteries to create the power system for the activation.

The antenna system for our 6M SOTA Station was built around an M2 Antenna Systems 6M3 Yagi and an 18 ft. push up mast from Max-gain systems.

All of this gear was carried to the site and setup in about an hour. A 25 ft. section of LMR-400UF coax completed the station. The mast was guyed with rings which allowed us to turn the mast/antenna combination to point the Yagi in any direction.

6M SOTA Activation

Between the SOTA/POTA activation and the June VHF contest, we made a little over 130 contacts on 6m. We did not have any real Es openings so most of our contacts were regional. Having the elevation provided by being on Pack Monadnock made us quite loud for the stations that could hear us. Several of our club members got on 6M and joined the fun. We did have a brief Es opening and managed to work a station in Alabama and one in Florida.

Mike, AB1YK has a much more portable 6M setup and used lower power to have some fun on 6M as well.

Al, KC1FOZ and Tom, KC1GGP put together a nice station and operated using battery power. Several other club members came out with a portable station or to watch and have fun as well.

Our first SOTA/POTA activation was a lot of fun and Anita and I are looking forward to the next one!

The Thirteen Colonies Special Event Begins Tomorrow – July 1

The Thirteen Colonies Special Event begins at 9 am Eastern Time (13:00 UTC) on Saturday, July 1st and ends on July 6th at midnight ET. The K2K NH team will have a full complement of top-notch operators on all bands and modes again this year including a dedicated QRP station. We’ve also designed a new QSL card for this year’s special event (above).

Take some time during the event and work K2K New Hampshire for your own copy of our new K2K QSL and don’t forget to send for your certificate. If you work a station from each of all Thirteen Colonies, your certificate will indicate a “clean sweep”. There will be two bonus stations that you can work as well. Check out The Thirteen Colonies Special Event Site for all of the details on the event.

This event is a lot of fun for all involved and may well be the largest special event in the world. The QSO count for the event last year was 139,772 contacts in about 6 days! We hope to hear from you during the event and DX stations are especially welcome!
