A Raspberry Pi Video Player for Ham Expo Displays

Dave, K1DLM recently prototyped a simple Raspberry Pi Video Player for use in our Ham Exposition Displays. We’ve built a number of these players to play video content at our upcoming Ham Expo Display at HamXposition at Boxboro in September. The article below shares information on the hardware and software we used to put these players together. The information should provide a useful start for many other Raspberry Pi projects.

Simple Raspberry Pi Computers have many useful applications in Amateur Radio. They can also be used to create a nice general purpose computing platform for many applications.

The hardest part of using the Raspberry Pi is getting the basic hardware and software components together to create a working system. This article explains these basic steps for a simple video player application that we use as part of our Ham Radio Expo Displays. I hope that this information is useful to others who might want to use the Raspberry Pi.

Video About Growing and Modernizing Your Amateur Radio Club

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.

GPS Time Server

GPS NTP

GPS Controlled Time Server

There are many reasons to have an accurate time source in your station. Getting the best performance from WSJT-X modes like FT8 requires your computer clock to be synchronized to within a second for example. You can set your clocks accurately using NTP servers on the Internet. This is the most common way that most stations set their clocks.

What if you are portable and don’t have Internet access or what do you do if your Internet connection goes down? One way to solve these problems is to use a GPS controlled NTP time server in your station. We recently installed one from Leo Bodnar in our station.

GPS NTP

GPS Antenna

This device is simple to install. It just requires an Ethernet connection to your network and a GPS antenna. The antenna is included with the unit. The antenna will need to be outdoors with a reasonably clear view of the sky.

GPS NTP

GPS Satellite Lock Screen

After a minute or so after it is installed and powered up, the unit will synchronize to the visible GPS satellites in your location and report its coordinates. This indicates that you have a good GPS system lock and that the clock in the unit is accurate to within a microsecond.

GPS NTP

NTP Summary Screen

The unit gets its IP either from DHCP or via a fixed IP address that you can program. Once the unit is set, you use its IP address as the NTP server in your software to set your clocks. You would set you NTP server in a program like Dimension 4 to accurately set your computer’s clock for example. You will want to disable your computer’s normal Internet clock setting function to avoid conflicts with Dimension 4. Once this is set up, your computer clock will be synchronized to the GPS system and will be very accurate and you will get the best performance from WSJT-X.

13 Colonies Special Event Begins Today!

K2K New Hampshire 2018 QSL

K2K New Hampshire QSL

The 2019 Thirteen Colonies Special Event begins today! There are stations in each of the states that grew from the original Thirteen Colonies plus two bonus stations – WM3PEN in Philadelphia, PA and a GB13COL in the United Kingdom. We have a great team of operators for the New Hampshire Colony this year. You can check them out here. You can find where the event stations are operating by using the 13 Colonies Spotting cluster.

2019 Thirteen Colonies Special Event Certificate

In addition to collecting the QSL cards from each of the state and bonus special event stations, there is a very nice certificate available for working one or more of the 13 Colonies stations. See the event website for details.

K2K New Hampshire will be operating from a number of locations in the great state of New Hampshire including from AB1OC/AB1QB. We will be operating SSB, CW, Digital (FT8 and RTTY), and on Satellites! We will have a QRP station operating as K2K/QRP and we are going to spend some time on 6m and perhaps 2m and 70cm if we have some Tropo openings. I hope that our readers will take some time and participate in the 13 Colonies Special Event this year. Its great fun for all involved. Happy July 4th the United States of America!

Final Field Day Station Test

What goes into an 11A Field Day? Well, for starters, 13 stations! We got together at AB1OC/AB1QB’s QTH a couple of weekends ago to set up ALL of our Field Day stations at once and test them together. Here’s a rundown of our final Field Day Station Test…

Source: Final Field Day Station Test – Nashua Area Radio Society

The Nashua Area Radio Society does a pretty big Field Day Operation each year. We will be 11A for Field Day 2019 with 4 towers up. Did you ever wonder what goes into pulling off a Field Day this large? Well, it’s all about planning and preparation. Take a look at the article above to see some of the preparation that we are doing for Field Day 2019.

Satellite Station 4.0 Part 8 – GPSDO Frequency Locking

Remote Gateway Rack with Satellite Additions

Frequency accuracy and stability become more challenging for transceivers that operate at 400 Mhz and above. Our 4.0 Satellite Stations operate at frequencies approaching 1.3 GHz and we want to be sure that their operating frequencies are accurate and stable. Our Flex-6700 SDR includes a GPS Disciplined Oscillator (GPSDO) so the radio and all of the transverters associated with the radio use the radio’s GPS disciplined 10 MHz output for frequency synchronization.

Portable Satellite Station 4.1

We wanted to add GPSDO frequency control to the Icom IC-9700 Transceiver in our Portable Satellite Station 4.1 station. Icom just released a version 1.11 firmware update for the IC-9700 which makes this possible.

Leo Bodnar GPSDO Kit

We choose a GPSDO from Leo Bodnar. The unit is compact, USB powered, and comes in a nice case which includes a GPS antenna and a USB cable. The unit has two GPS disciplined frequency outputs which can be configured for a wide range of frequencies and levels via a Windows application.

GPSDO Connected to an IC-9700

The GPSDO is connected to the 10 MHz reference input on the back of the IC-9700 with a BNC to SMA cable and the GPSDO is powered via a USB connection to our iMac. We configured the GPSDO output frequency to 10 Mhz and for an output level of +7.7dBm (drive setting 8mA). We also added a 20 dB pad in line with the GPSDO output to better match the drive level requirements of the IC-9700’s 10 MHz input.

Locked GPSDO

The GPSDO will lock in a very short period of time (less than 1 minute) once GPS antenna and power connections are made the unite t. The unit has a red LED on each of its outputs and the unit is GPS locked when the LEDs are on and not flashing.

Configured and 10 MHz Input Locked IC-9700

The last step in the setup process is to configure the IC-9700 to sync its reference frequency to the 10 MHz input. This is easily done in the IC-9700’s Set/Function Menu.

It was pretty easy to add GPSDO locking to the IC-9700 and the arrangement described here works well. While this upgrade is not essential for satellite operation, it’s nice to know that our satellite transceiver frequencies are accurate and stable.
