Another new radio from Icom based on their SDR platform. This looks like a great radio for Satellite and EME use. We’re going put in a pre-order for this radio and will plan to include it in our Portable Satellite Station. I’ll post more here as details become available.

Our planned route is shown above. We are planning to operate while we are moving. Also, we plan to stop on County Lines and activate multiple Counties at the same time. wherever possible.

You can find the rules and information about the NHQP here. We hope to work you this weekend!

Portable Satellite Station Design and Operation

Building and Operating a Portable Satellite Station Presentation

Portable Satellite Station Design and Operation Presentation

Anita and I attended the New England Regional Hamvention this past weekend. We gave a presentation on Portable Satellite Station Design & Operation there. You can view a copy of our presentation here.

The Videos from our presentation follow below –



We did two additional talks about the Nashua Area Radio Club’s activities including one on our High-Altitude Balloon Project. You can view those presentations here.

Also, we are planning to have our 2.0 Portable Satellite Station setup at the Nashua Area Radio Club’s upcoming Technician License Class on Sept. 30 – Oct. 1. If you are in the area and would like to see the station in operation, please contact us at activities@n1fd.org to arrange for a visit. If you’d like to register for one of our license classes, you can do that here.

Spark Day at the Nashua Academy for Science and Design – Spring 2017

Explaining Amateur Radio to ASD Students

Explaining Amateur Radio to ASD Students

John Keslo, W1MBG, Jamey Finchum, KC1ENX, and I (all members of the Nashua Area Radio Club) recently had the chance to again visit the Academy for Science and Design (ASD) in Nashua, New Hampshire to provide an Introduction to Amateur Radio for the students there. ASD’s goal is to be a world-class school that specializes in science, engineering, mathematics and design for students in grades 6-12.

ASD periodically holds SPARK (Symposium Promoting Advancement of Real-world Knowledge) conferences, which enable ASD students to learn about areas which might help them to develop careers in Science, Technology, Engineering and/or Math (STEM).

The students at ASD are extremely bright and are highly motivated to develop STEM careers. We had about 65 students elect to attend the two sessions that we presented and the kids showed a lot of interested in our presentations.

Explaining Our High-Altitude Ballon Project

Explaining Our High-Altitude Ballon Project

We began each session with some classroom time where we explained what Amateur Radio is about and some of our club’s Amateur Radio  projects. We talked about and showed components of our High Altitude Balloon Project, our Satellite Ground Station and our Field Day activities. The interest level among the kids was high and lots of questions were asked.

We also put together an HF GOTA station in the lobby of the school. This gave the kids a chance to get on the air and experience Amateur Radio first hand. After the kids got over the usual “mic-fright”, they had a lot of fun.

We are looking forward to our next opportunity to participate in ASD’s SPARK Day in the fall. This is one of the most enjoyable events of the year for me.

High-Altitude Balloon Launch and Tracking

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 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

Setting Up Our Gear

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.

Assembled Flight Platform

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.

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 the balloon.

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.

Launch!

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 the HAB

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 on-board sounder allowed the landing location to be pinpointed and the flight platform recovered with help from a local resident.

The on-board 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, 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.

Portable 6M Station for SOTA and Contesting

Fred, AB1OC and Curtis, N1CMD Operating

I got really exited, 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 station in preparation for the activation.

Solar Panels

Solar Panels

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 a MPPT solar charing system and two LiPo batteries to create the power system for the activation.

6M Antenna Going Up

6M Antenna Going Up

The antenna system was built around a M2 Antenna Systems 6M3 Yagi and a 18 ft. push up mast from Max-gain systems.

Portable 6M Antenna

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 guy’ed with rings which allowed us to turn the mast/antenna combination to point the Yagi in any direction.

Anita, AB1QB and Curtis, N1CMD Operating in the June VHF Contest

Anita, AB1QB and Curtis, N1CMD Operating in the June VHF Contest

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 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!
