A Piece Of Ham Radio History – Do You Know What This Is?

Every now and again one comes across a piece of Ham Radio History. Anita and I had this experience recently during our vacation in Florida. For example, we can across an artifact that we had heard about from Charle, W1CBD but had never actually seen during a recent visit to Florida.

Pretty Basic HT Transceiver

This is a Motorola  MX-340.  This radio was a 5w UHF (or sometimes VHF) FM rig that was popular for commercial applications in the 1970s. You can learn more about the rig here.

A Very Special HT Transceiver

So I bet you are wondering “What makes this old HT so special? Why is it a piece of Ham Radio History?”. Well, here’s a hint – it flew aboard this:

Yup, the little HT flew aboard the Space Shuttle.  Here’s more about our little HTs role via an excerpt  from Wikipedia :

The Shuttle Amateur Radio Experiment (SAREX), later called the Space Amateur Radio Experiment, was a program that promoted and supported the use of amateur (“Ham”) Radio by astronauts in low earth orbit aboard the United States Space Shuttle to communicate with other amateur radio stations around the world. It was superseded by the Amateur Radio on the International Space Station (ARISS) program. SAREX was sponsored by NASAAMSAT (The Radio Amateur Satellite Corporation), and the ARRL (American Radio Relay League).

STEM Learning Through Space and Ham Radio

Ham Radio History - SAREX

Ham Radio has been a STEM learning tool for a very long time. An early example of this was the Shuttle Amateur Radio Experiment  (SAREX) program. SAREX was a partnership between NASA, ARISS, and the ARRL. Its success in bringing Ham Radio to schools and other educational venues led, in part, to the creation of ARISS.

How All Of This Effects NARS

And ARISS, of course, has provided NARS the opportunity to be part of bringing contacts with astronauts aboard the International Space Station (ISS) to schools here in New Hampshire, around the United States, and around the world.

There are many such examples of Ham Radio History that resulted in great things for many people. Perhaps you know of one? If so, please consider taking writing about it here on our Blog.

A Potential New Project – A Nashua Area Radio Society Club Station

We are currently considering a new project for the Nashua Area Radio Society – potentially building a club station for our members to use. We know that many folks, particularly new and recently upgraded Hams would likely use and benefit from a club station if we had one.

Why Build A Club Station?

A club station would provide many opportunities for our members to build skills and have fun with Amateur Radio. It would also provide an important emergency communications resource to members of our community. Some additional uses of a club station might include:

Space Needs

I wanted to share some ideas about what capabilities we are thinking about including in such a project. First, we’d certainly want to have a permanent space that our members could access and use to make contacts. This means that we’ need to find a location that could support 200 sq ft or more of space for equipment and operators. Space would need to be reasonably accessible to our members and have adequate power, light, heat, and Internet access available.

Possible Club Station Capabilities

Hex Beam Directional Antenna
Hex Beam Directional Antenna

A club station would be an on-going project that would likely evolve and grow with our club’s member’s interests and skills. Some capabilities that we might initially include would be:

  • A 100 w HF station for at least 40m – 10m
  • A combination of a wire (40m) antenna and a directional (Hex beam or a tri-band 20m-10m) antenna
  • An FM repeater transceiver and antenna
  • A computer for logging and other Amateur Radio activities such as Digital operations

HF Transceiver - IC-7300 - Club station radio

100W HF Transceiver Example – Icom IC-7300

Longer-term additions might include:

  • 6m and 80m capabilities
  • Ability to operate the station remotely from home and other locations via the Internet
  • A satellite ground station
  • A 500w amplifier for HF
  • Additional contesting capabilities

Getting Started – What Do We Need?

We are exploring the idea of a club station at this time. The first step in the project would be to find a suitable space that we could use. We’re looking for a location that is centrally located in the Nashua Area. A Loft or similar space at someone’s QTH or a space that is part of an existing business, educational facility, or other public space would make great potential candidates for a club station.

Perhaps you have or know of someone who has a loft or other suitable space that we might use. The benefit to someone who could help us in this way would be ready access to a top-notch Amateur Radio Station along with the satisfaction that comes from helping our members develop their skills and support our community in times of emergency.

If you know of a space that you think we might consider, please contact us at [email protected]. We are also looking for members who would like to help us with this project. We hope to find a space and undertake a club station project in 2020.

Winter Field Day 2020 Final Station Test

Winter Field Day 2020 is almost here! A few weekends ago, Jerry K1OKD, Jon AC1EV, Andrew NF1H, Anita AB1QB, and I got together at our QTH to complete the final station test for our planned 5O operation in Winter Field Day (WFD).

Portable Wireless Networking

In preparation for WFD 2020 and our test, I built a new Wireless Networking Pod. This unit was made possible by a very generous donation of a router with LTE wireless access capabilities by Dave, K1DLM.

The system consists of the following components:

Our Networking Pod will be used in a number of ways to support Nashua Area Radio Society activities including Youth Expos, Ham Bootcamps, Field Day Operations, Portable Operations, and others. It provides a wired and wireless (via WiFi) network capability including DHCP, DNS, Firewall and other IP services that can be used to network computers running the N1MM+ logger and other apps. It can also be used to provide wireless internet access via LTE in situations where we need this.

Station Testing

We had already assembled and tested our two Winter Field Day 2020 HF/VHF+ Stations during a previous station test so the final test was focused on the three planned HF stations and the networking of the N1MM+ Loggers that we’ll be using.

We set up the three HF stations and connected the associated laptop computers to the Network Pod for the test. Each of our HF stations includes:

We also tested our Triplexer and Bandpass Filtering system along with the radios.

160m All-Mode Station Main N1MM+ Monitor

A big part of this test was to get the N1MM Logger+ working with the radios and in a network configuration using the Networking Pod. Networking N1MM+ enables us to maintain a common log across the 5 stations in our Winter Field Day setup. All of the stations were also set up for SSB Voice, CW and Digital operation via N1MM+.

All of the station tests are complete and we are ready for Winter Field Day! Come on out and join us for what I am sure will be a lot of fun!
