Not Your Grandpa’s Ham Radio
Dennis W6DQ displayed his Flex 1500 software defined radio with 10 GHz and 24 GHz transverters. There were many questions about SDRs and many visitors were surprised to learn ham radio operators have this technology. But this is another example of what radio hams are using these days. The system Dennis showed is actually three systems in one: The SDR, which is being used as the “intermediate system,” and transverters (transmitter-receiver-converters) for 10 GHz and 24 GHz microwave ham radio. The posters briefly explain the transverter system:
APRS: Automatic Packet Reporting System – and High Altitude Ballooning
Someone asked if it would be possible to track a high altitude balloon using ham radio. It is possible to track a vehicle, aircraft or person using the amateur radio application called APRS, the automatic packet reporting system. Basically, the system consists of a two-way radio (usually for the 2m ham band), a GPS receiver, a modem to interface/control the data to and from the GPS, and an antenna for the radio and the GPS.
By coincidence, I am collecting parts for such a system, see the photo above. The radio antenna is on the left – it is a piano wire dipole for the 2 meter ham band. On the upper right is a Byonics Tiny Trak SMT – the interface between the two-way radio and the GPS. Inside the orange plastic box is an old 2m handie-talkie, with its cabinet parts and battery pack removed. Not shown in the picture are the other ingredients, which include a tiny GPS module and the video cameras for Amateur Television (ATV).
Here are some links I used in my research.

The 2014 Bay Area Maker Faire is now history.
One of the Maker Faire team members, Brian Yee, W6BY, was not able to join us – we are all hoping Brian recovers quickly from his injury.
Dennis Kidder, W6DQ and Marty Woll, N6VI (ARRL Southwestern Division Vice Director) – along with several University of California, Davis engineering students and their faculty advisor, Professor Leo Liu, displayed and demonstrated their projects to the Maker Faire crowd. Estimated attendance: 120,000.
Here’s a two minute “drones eye view” of the Maker Faire 2014
Highlights during setup day included meeting Anouk Wipprecht, the fashion designer; Tenaya Hurst, the Arduino Woman; and the paella dinner, sponsored by Liquid Wrench.
This year, I included a handout of frequently asked questions about Amateur Radio, and it turned out to be useful. However, we quickly ran out of copies, so I am pasting the text here:
What Are We Doing at Maker Faire 2014
Not Your Grandpa’s Ham Radio
Thank you for your interest in our Maker Faire display. We are radio communications experimenters using the microwave Amateur Radio (ham) frequencies.
Who are we?
We are licensed Amateur radio operators (“hams”).
Is this like CB?
Yes and no. Ham radio is similar to CB because we use two-way radios to talk to each other, but hams can communicate using Morse code and computers in addition to voice, and we even have our own satellites. Ham radio requires a license issued by the Federal Communications Commission (FCC) in the USA.
How far can you talk?
We can communicate with other ham stations around the corner or across the globe, depending on a variety of factors that affect the way radio waves travel. The equipment we are using here operates on frequencies that generally follow line-of-sight paths. However, through experimentation, we find that signals can be reflected against objects such as buildings, trees, islands and mountains, to extend the range. Using these techniques, we are able to contact other stations hundreds of miles away.
What kind of radios are you using?
No commercially-built, “off-the-shelf” equipment for these frequencies exists, so we must build our own equipment, or modify commercially-made equipment meant for other services, such as cell phone, wireless links and radar systems.
How much does this equipment cost?
Like any other hobby, people spend as much or as little as they can afford. Most people involved in ham radio spend as much as any serious stereo enthusiast, amateur photographer or woodworker.
Where can I get more information?

This is our third consecutive appearance at the Bay Area MF, and continues my theme of showing how some ham radio operators continue the tradition of “teaching, mentoring, making, modifying, repairing and improving” radio and radio-related technology. Read my post about ham radio and the Maker movement.
Today’s ham radio operators have an incredible amount of exotic surplus material that can be converted into everyday use on the ham radio bands. Grandpa certainly never heard of surface-mount technology, talking on homemade 47 GHz transmitter-receiver systems or pocket-sized, satellite navigation systems (GPS). But he sure did mentor, make, modify, repair and improve the equipment in his bedroom radio station…..

Dutch fashion designer Anouk Wipprecht – who mixes high fashion with microprocessors and fiberoptic fabrics, is scheduled to present “Robotic Fashion and Intimate Interfaces” on Saturday May 17 at 11:30 AM on the Center Stage at Maker Faire Bay Area.
Anouk made the microprocessor-controlled fibre optic and LED costumes for the Black Eyed Peas for the Super Bowl XLV half time show.
I met Anouk at a Crash Space meeting in 2011 – she is fascinating!

The big show is coming soon. Last year, over 120,000 people attended this science-art-food-engineering-fun-educational event.
This year, my team (Dennis Kidder W6DQ, Brian Yee W6BY and Marty Woll N6VI) will bring their newest ham radio projects to show. We will continue with my original theme called “Not Your Grandpa’s Ham Radio.”
A group of University of California, Davis (UCD) engineering students will join us to demonstrate their experiments and projects. These new engineers are getting a great head-start by doing hands-on, practical experiments and projects that go beyond their lecture and textbook learning.

The First San Diego Mini Maker Faire Takes Off!
A Mini Maker Faire makes its debut in San Diego at the Del Mar Fairgrounds. Despite the sometimes heavy rain, most all of the exhibitors (Makers) showed up. San Diego Mini Maker Faire organizers kept the weather forecast updates on a positive note: “…Forecast: 100% Chance of Great Exhibits” – an excellent promotional phrase.
There were around 5,000 tickets purchased, amazing for a first run in inclement weather. Another positive indicator of interest in San Diego area “Making” is the number of Learn to Solder kits that were made during the event – all 350 of the blinky LED boards were built on Saturday.

In addition to visitors from our own radio clubs (Rein W6SZ and his XYL, Larry K6HLH and his XYL, Ed W6OYJ, Michelle W5NYV and Paul KB5MU) many other San Diego area hams stopped by. As in previous exhibits, there is a pattern: Those who have a callsign but are not on the air, those who have callsigns and are active on the FM repeaters but not much else.
But this is one of the reasons I developed the Maker Faire theme called Not Your Grandpa’s Ham Radio – I want to show something new to licensed (active as well as inactive) hams, and I want to expose those not familiar with ham radio to what some of us are doing with twenty-first century technology in our hobby – we are embracing and doing hands-on experiments with microprocessors/microcontrollers, GPS, micro- and millimeter-wave construction techniques and other exotic radio-related technologies. We are having fun while learning new skills and expertise.
I hope this idea spreads to other active ham radio groups in other locations – surely there are other hams like us who are doing something more interesting than just talking to strangers, friends and family, right? If you are a ham radio operator and are involved in doing something interesting, let me know and we should join forces to help each other increase interest and participation in this concept – since – as most all hams know – being a Maker is certainly not a new idea!
Here are some pictures from the San Diego Mini Maker Faire. I have two videos posted on my YouTube channel: Walt’s Radio Wave Demonstration and The Electric Giraffe
Map showing the KH6WZ APRS beacon location. The location is approximate, I had to simulate the GPS coordinates since signals were blocked in the steel and concrete exhibit hall.

Despite the rain, there was a constant crush of people in, near and around the Not Your Grandpa’s Ham Radio booth at the 2013 San Diego Mini Maker Faire

Not Your Grandpa’s Ham Radio at the San Diego Mini Maker Faire – We were lucky there was a no-show next to us, so we combined the empty space with ours at the end of an aisle – good show!

A visitor (striped shirt and black hat) tries some of the hands-on microwave physics demonstrations made by Walt

Dennis brought his 10 GHz / 24 GHz dual band station with software defined radio and notebook computer. The “waterfall” display is used to visually indicate very weak to very strong signals across the receive band. The digital signal processing in this system can improve signal reception

Two more projects by Dennis – On the left, a transmit/receive sequencer, used to turn on or turn off circuit modules (or functions) in a specific order. To the right is a circuit under construction/proof of concept receive system using direct synthesis.

Jason W6IEE brought his airplane IFF detector. I will get a better description of his display in a later update.

Here’s one of Kerry’s gadgets – a surplus QualComm microwave diode being used to generate a wideband microwave signal. Intended to be used to detect a microwave signal to verify transmitter operation, it can also transmit a signal for voice communication – in this case, to my 10 GHz transverter system shown in the background.

Here are three of my projects. On the far left, is a microwave field strength detector, this is used to demonstrate vertical or horizontal polarization, the KH6WZ unit in the middle is an APRS beacon, transmitting GPS coordinates (this unit generated and transmitted the GPS coordinates used to generate the location on the APRS locator map at the top of this page) and at the far right is my distance record-setting 10 GHz microwave transmitter-receiver system.

Visitor’s to Not Your Grandpa’s Ham Radio at the San Diego event were able to see some vintage 1960s microwave ham radio units – like this “Synplexer” built by Ed Munn W6OYJ. A pair of these units were on display so we could demonstrate full duplex wide band communication on 2.4 GHz (2400 MHz)

It’s great to see young ladies get excited about technical things. There’s a San Diego area high school program that includes a robotics class and competition

Quadcopters seem to be trendy with Makers. Maybe this is where Jeffery Bezos got that idea for small package delivery?

MakerPlace – a place where fellow Makers can gather and make, share and borrow tools and ideas to make things. Funny, it sounds like what a good and active ham radio club should be
