Field-Day Kick-off Meeting

I am really excited to be leading the field day effort for the Nashua Area Radio Club this year.  Since this is my first time, I will be relying on the club members to help me make this a success.

It is rapidly approaching, and with this in mind, I’ve scheduled an initial “kick-off” meeting for Sunday, March 5th at the Nashua Library in the Hunt Room from 1-3 PM.  I’d love to see all team leads from last year, as well as anyone interested in participating this year to please attend.  My intention is to identify a planning team at this meeting to start working through all the details.

The first item on the agenda will be to identify potential locations for this year.  With this in hand, we will create a site survey crew to evaluate the options and decide which site best fits our needs.  Ideally, the site will be centrally located to Nashua, and allow for public access.  In order to accommodate the towers, we will need a field between 600-1000 feet long North to South, and at least 120 feet wide.   A 1000-foot site would allow us to erect 3-towers.  It would also be ideal if there are restroom facilities, and potentially access to a kitchen / cafeteria.  This is especially important if there is inclement weather.

We also need to decide what type of station we should run this year, and what type of antennas are needed.  Last year, we erected a V-beam array for 40-meters which was very effective.  We may want to consider adding a second one.  Other questions remain open, such as should we have more digital operations, a VHF station, or perhaps an enhanced satellite setup?

We also need to determine what class and entry strategy we want to use this year.  In 2016, we operated as a 7-Alpha, as this seemed to be a sweet spot.

It takes a village to pull this event together, but as the old adage goes “many hands make light work”.   I hope to see you all on the 5th.

Our January Visit to MakeIt Labs!

The highly publicized event — the event of the month — went off with a bang! On Jan. 28th, the Nashua Area Radio Club paid a visit to MakeIt Labs to promote Amateur Radio with maker folks. It’s a natural union if you think about. Technologists/scientists/engineers/self-taught DIY’sters and amateur radio folk are essentially one in the same beast. So why shouldn’t they be interested?

We had a super great turn out from many in the club and those external to the club or from MakeIt Labs itself. Representing the Nashua Area Radio Club, we had Fred (AB1OC), Anita (AB1QB), Jamey (KC1ENX), Abby (KC1FFX), Connor (KC1GGX), Brian (AB1ZO), Mike Struzik (AB1YK), Bill (W1TWO), Mike Ryan (K1WVO), Mike Rush (KU1V), and Tom (AB1NS) (Forgive me if I forgot you).

The idea was to set up the every-popular GOTA station, but also demonstrations of other amateur radio technology to hook the masses with. As a result, we had Fred’s digital amateur TV station, a tabletop satellite station, and Mike Struzik brought along his home-brewed BitX20 transceiver complete with plans, schematics, and a demo keyer. (Talk to Mike for further details/websites. He’s awesome about answering questions and exposing people to what they need to do to get started.)

We spent a solid 6-7 hours at the facility, even roping in some new interest from folks who happened to see our advertisements for the event both online and in stores/businesses around Nashua. It’s clear that word is spreading about the work that the Nashua Area Radio Club is trying to do; we are engendering interest slowly, but steadily. Essentially, the trend is upwards.

We hope that down the road, we can enjoy a lasting partnership with MakeIt Labs and encourage more members of our club to drop in, see the facility, hang-out for a bit, and explain to new folks about how this hobby is damn close to one of the best hobbies out there!

So, until next time, and until my next posting (and hopefully that one will be a bit witty’er — didn’t have enough coffee today), make sure you eat, sleep, “repeat”! (That’s what my t-shirt says that my wife bought me)

Our Latest “Tech Night” – A DSO138 Oscilloscope Kit Build

Our latest Tech Night became a Tech Day this past weekend. We got together on Saturday afternoon to build another kit – the DSO138 Oscilloscope. We had a great turnout with over 15 kit builders and helpers present.

Finished Oscilloscope Kit

Brian, AB1ZO choose this really cool kit for us to build. Here are some specifications for the finished DSO138 Oscilloscope kit:

  • Analog bandwidth: 0 – 200KHz
  • Sampling rate: 1Msps max
  • Sensitivity: 10mV/Div – 5V/Div
  • Sensitivity error: < 5%
  • Vertical resolution: 12-bit
  • Timebase: 10us/Div – 50s/Div
  • Record length: 1024 points
  • Built-in 1KHz/3.3V test signal
  • Waveform frozen (HOLD) function available

The kit came with all Surface Mount parts pre-installed.

The kit included a very nice case to finish off the project. This was a pretty big project to complete in a single afternoon but quite a few of our builders completed their kits and got them working!

The gallery below contains more pictures from our kit build. Everyone was very focused on the building process as we all wanted to get our kits to work in the time we had together.

Some folks did not quite get their kits completed and are planning to finish them at home. The following are some links and videos to help.

Here are some videos which show the assembly of the kit and its enclosure and the operation of the completed scope. The first video shows the kit in operation.

 

 

 

 

I know that Brian is planning to do more kit builds throughout the year so be sure to keep an eye on our Tech Night page to see what is coming!
