Jamey, AC1DC Presenting in the ARRL Forum at Dayton 2019

The ARRL gave the Nashua Area Radio Society a Forum at the Dayton Hamvention(R)this past year to talk about how we approached Growing and Modernizing our club. The ARRL has produced a video of our Dayton Forum presentation. You can view the Video along with a copy of the presentation via the link which follows…

Dayton Hamvention(R) 2019 ARRL Forum – Growing and Modernizing Your Amateur Radio Club

The Nashua Area Radio Society has grown from about 35 members to over 225 members in less than 4 years. The presentation contains ideas and programs that have worked for the Nashua Area Radio Society’s (NARS) as part of our efforts to modernize and grow our club.

We have been sharing this presentation via the Internet with other Amateur Radio Clubs. All that is required is an Internet connection capable of streaming video and an associated computer with a projector and speakers. We would like to invite our readers who might want us to do a similar presentation at one of your club meetings to reach out to us via an email to ab1oc@arrl.net.

Anita and I have been working to grow the Amateur Radio Service through our work at the Nashua Area Radio Society. The Nashua Area Radio Society is a 501c(3) public charity whose mission is to:

  • Encourage and help people to become licensed and active in the Amateur Radio Service
  • Spark Interest among Young People in STEM Education and Careers through Ham Radio
  • Provide training and mentoring to enable our members to improve their technical and operating skills and to be prepared to assist in times of emergency
  • Sponsor on-air operating activities so that our members may practice and fully develop their operating skills and have fun with Ham Radio!

The Nashua Area Radio Society has created many programs designed to provide STEM learning experiences and training through Amateur Radio. Some of these include:

To carry out our mission, we have formed close relationships with several schools. This helps us develop and deliver effective, high-quality programs that bring learning through Amateur Radio to young people. You can read more about what we’re doing via the link at the top of the page.

We provide many of these services either free of charge or at a very modest cost. We count on the generosity of our members, friends, and the Amateur Radio community to raise funds to support our work.

We hope that our readers will consider supporting our work at the Nashua Area Radio Society by using Amazon Smile and designating us as your favorite charity and/or by making a donation to our current fundraising campaign (click on the badge below).

We have been working on project to scale our open house activities to provide an opportunity to learn about Amatuer Radio and to showcase some of the modern, “hi-tech” aspects of the Amatuer Radio Service. This project was debuted at the NETT event at NEAR-Fest. We used our Portable Satellite Station, Remote Operating Gateway, and our Mobile HF Stations as part of this activity. There might be some ideas here that you can use to create an exciting operating activity at you local club or Ham Fest.

Upgrading our 2.0 Satellite Station for ARISS Contacts

by

0

We have been working with Hudson Memorial School near Nashua, NH to prepare for a possible ISS crew contact. The ARISS folks work with schools and their Ham Radio helpers to prepare for these contacts. ARISS provides recommendations for ground station equipment to help ensure a good experience for the students. The ground station recommendations provide a solid set of specifications to support communications with the ISS on the 2m band. The recommendations include things such as:

  • A requirement to build both a primary and a backup ground station
  • Radio and power specifications (a 200W amp is recommended)
  • Antenna specifications including recommendations to provide for switchable LHCP and RHCP
  • Computer controlled azimuth/elevation positioning of antennas to track the ISS
  • Use of a receive preamplifier at the antenna
Portable Satellite Station 3.0 Antenna System

Portable Satellite Station 3.0 Antenna System

We have recently completed construction and testing of our Portable Satellite Station 3.0 which was built specifically to meet the primary station requirements for our ISS contact.

Our plan is to add some upgrades to our Portable Satellite Station 2.0 to create a Portable 2.1 Station which meets the backup station requirements. These upgrades will include:

All of the equipment needed to upgrade our 2.0 Portable Station to 2.1 is either here or will arrive shortly. Here’s some more information on the planned equipment.

Icom IC-910H Transceiver

The Icom IC-910H was Icom’s flagship Transceiver for Satellite work before the IC-9100 was released. It’s a very nice satellite radio! Dave, K1DLM graciously lent us his IC-910H for use in our backup station.

Green Heron RT-21 AZ/EL Rotator Controller

We already have a Green Heron Az/El Rotator controller setup for the Yaesu Rotator system on the 2.0 Antenna Tower and we will be reusing it for the 2.1 station.

M2 Antenna Systems recently added a new 2M polarity switch, the PS-2MCP8A, designed for use with the 2M antenna in their LEO Pack which we are using in our 2.0 Antenna System. We will be installing this relay as well as a PS-70CM polarity switch relay for the LEO pack’s 70cm antenna as part of the 2.1 Antena System upgrade.

DXEngineering EC-4 Control Box

We will add another DXEngineering EC-4 BCD Control Console to control the polarity switching relays on the upgraded antennas.

The final new component in our 2.0 to 2.1 upgrade is the addition of a 200W RM ITALY LA 250 power amplifier. We have opted for the version of this amplifier with the cooling fans. The unit is very well made and we are anxious to see how it performs on the air.

Some of our readers might be wondering what we are planning to do with all of Portable Satellite Ground Station equipment in the long run? We plan on keeping the 1.0 Portable Station for grid square activations and demonstrations. Its simple, battery-powered approach and small antenna make it ideal for this sort of work.

The upgraded 2.0 Portable Station with its enhanced polarity switching will become our transportable station for License Class and Field Day use. It will be converted at the end of 2018 to use our Icom IC-9100 Transceiver that is currently part of the 3.0 station.

We plan to use the Portable 3.0 Station through the year (2018) to support the planned ARISS contact, Field Day, and some demonstrations at local Ham Fests and schools. Once these are complete, we plan to permanently install it here at our QTH and it will become our main satellite ground station at our home QTH.

You can view all of the articles about our Portable Satellite Stations via the links below.

We will begin construction of the 2.1 upgraded station once a few remaining components arrive here. We plan to share some more about the construction and initial testing of our 2.1 Portable Station here.

The Nashua Area Radio Society is planning to launch another High-Altitude Balloon (HAB) this coming Saturday, October 28th at 15:00z (11 am Eastern Time) from Winchester, NH USA. Our Balloon will carry a 2m APRS transmitter operating on 144.390 MHz and will be using the call sign N1FD-11. You can also track our HAB via the Internet using aprsi.fi. We expect our HAB’s flight to last about 2 1/2 hours and reach an altitude of over 105,000 ft. The balloon will also be carrying two video cameras to capture near-space video during the flight.

Our HAB launch is part of a STEM learning project with local High School students here in New Hampshire. You can read more about our project and see a video from our previous HAB launch and flight on our website here. We hope that you’ll track our HAB!

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 include 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 here in New Hampshire. You can read more about the project and our STEM work on our club’s Blog here.

Enjoy!
