Ham Radio Aviator Departs for Round The World Flight

 

FOR IMMEDIATE RELEASE

Ham Radio Aviator Departs for Round The World Flight

Brian Lloyd WB6RQN Flight Commemorates 80 Years Since Earhart

Miami, Florida, USA, June 1, 2017 – As pilot Brian Lloyd propels his single-engine plane named “Spirit” into the sky on a solo round-the-world adventure, he commemorates Amelia Earhart’s famous flight eighty years ago on this date in 1937. He is communicating live via radio with Ham operators while flying. The two month flight will follow Earhart’s historic route to circumnavigate the world at the equator, which starts in Miami, skirts the chain of Caribbean islands, then along the coast of South America, crosses the Atlantic eastward, and then onward around the world.

Prior to departure from his home airstrip in Texas, USA, Brian Lloyd said, “I am driven by the spirit of historic flights. It is important to remember the aviation pioneers like Amelia Earhart, and their contributions to aviation. Their bold actions made today’s air travel possible for all of us.”

While he is in the air, using the call sign WB6RQN, Brian encourages Ham radio operators to contact him on the following frequencies: 14210.0 kHz USB, 14346.0 kHz USB, 18117.5 kHz USB, or 7130.0 kHz LSB. His HF (High Frequency) radio is a Mobat Micom-3 transceiver, with a maximum power of 125 Watts, and an antenna under the fuselage. He also utilizes ALE (Automatic Link Establishment) on the Amateur Radio HFLINK frequencies http://hflink.com

Brian Lloyd’s radio schedule is posted on the project’s website http://projectameliaearhart.org/ham-radio

“I’ve been a ham radio operator since 1976 and enjoy radio communications very much. The plane is set up with HF radio for aeronautical purposes with the normal pilot headset controls. The flight route has some very long legs, so I will have plenty of opportunities during June and July to talk with ham operators while flying over the world’s oceans,” Brian said.

Commercial airliners fly long distances every day, but non-stop ocean flights are quite difficult for small propeller planes, which have limited range. To make it possible, Brian Lloyd modified his 1979 Mooney airplane to carry 150 gallons more fuel, then equipped it with modern navigation equipment, long range radio, and satellite communications. Still, the flight is not without risk, and special safety gear must be taken along. The public can track his flight on the web, social media, as well as Ham radio.

About: Brian Lloyd, 62, is a pilot, flight instructor, engineer, educator, and radio operator.  He lives near San Antonio, Texas, USA. The commemorative flights are co-sponsored by The Classic Aircraft Aviation Museum, a non-profit in Texas, and many other individuals who contribute to supporting the flights through donations.

Dayton Hamvention Military Radio Check Ins 2017

Yep thats me on 6m

Year #1 is in the record books for the Dayton Hamvention at its new
venue in Xenia OH. Despite rain and mud in the flea market area, most
comments I’ve heard have been positive, and you have to give a round of
applause to the Hamvention volunteers who were faced with a Herculean
task and yet rose to the occasion.

For many of us, the three Saturday nets are a highlight of the
Hamvention and this year was no exception. I’d prepared a bit of a
surprise which performed very well – I used a homebrew 2 watt 75 meter
handheld transceiver to check into the 3885 AM Net. I plan to write
this rig up in an article for Electric Radio as I think it contains some
circuit ideas that will be of interest. It is not a clone since it
incorporates hybrid circuitry and only one tube, but it is my tribute to
the BC-611 and those who designed such a compact radio using the
technology available at that time.

As usual Joe WA4VAG conducted the Old Military Radio Net in fine
fashion, assisted by KB0SFP. The net control station this year will be
of particular interest to this group – Joe used a complete U.S. Navy
ARC-5 set, run from dynamotor power, as can be seen here:

A list of check-ins for the 3885 AM net, 17 meter HF Pack Net, and the
51.0 Mhz Cold War Net follows.

Dayton Hamvention 2017 Arrow Communications BUS Buildathon – QRPme RF Probe Kit W1REX

 

Dayton Hamvention 2017  BUS – QRPme No Solder RF Probe Kit W1REX

52 happy hams got to smash a world record for a QRP kit buildathon on a BUS coming back from Dayton with the Arrow Communications club. I was the only VE3 (actually the chosen ONE – hihi) on the ride and I volunteered to help out with the build. No soldering required and no parts lost.

This is an excellent club project night kit, scouts kit or a beginners kit.

Often we wish to examine an RF voltage to see if a circuit is “alive,” and perhaps to adjust it. An RF Probe is an important tool to have for electronics and radio troubleshooting. You can measure RF voltage in your solid state circuits, and trace RF through your new designs or malfunctioning circuits. They allow you to probe into different parts of circuits to find where you do or do not have an HF/VHF/UHF signal. With this information, you can find where your signal disappears. In turn, this suggests where there is a bad component or solder joint in the device you are troubleshooting. Do not exceed 50V and will not be useful for Tube based circuits due to High Voltage. You will be able to detect RF voltages in the range of .25v to 50v

Building the kit is easy once you have figured out the colour code. Pay special attention to the polarity of the diode. I would recommend to actually solder it once tested and install in a small pill bottle with a thick wire for a probe element. This is a perfect tool for troubleshooting your next qrp kit from QRPme.com

Thanks to Joyce, Jim WD8RWI and Shawn KD8YMV for acting as superstars

52 happy builders 10 minutes later – really its that simple

So, how do we use this thing? As per N5ESE

RF Probe is to connected the banana-plug end to the +/- jacks of your DC Voltmeter: (not AC).

To use the RF Probe for signal tracing in a malfunctioning RF circuit or a homebrew circuit, connect the alligator clip to a convenient “ground” or “common” point in your circuit. Often this is the chassis. Most of the time, you’ll be probing at the base/gate, emitter/source, or collector/drain of a transistor, one either side of a coupling capacitor or transformer, or at the input or output of an IC. Because the circuit’s RF must overcome the diode’s barrier potential (of 0.25V, for our 1N34A), voltages much less than that won’t read at all, and voltages less than about a volt won’t read very accurately. Typically, RF and post-mixer-amps in receivers don’t have enough RF voltage, unless you inject a very strong signal at the input.

I recently used my RF probe to troubleshoot my dead TenTec Scout, which had suddenly quit transmitting in mid-QSO. I connected the rig to a dummy load, then keyed it while probing. Using the probe, I was able to follow a steadily increasing RF signal through the transmit chain, from the oscillator through the transmit mixer, to the pre-driver, and the driver. The actual voltage measurements weren’t important, just that they were increasing from stage to stage where expected. Then, (whoops!) the driver’s base circuit had 6 Volts, but the collector circuit only had only 0.1 Volts! The driver transistors had gone south!

You can also use the RF probe to measure RF power with reasonable accuracy, up to about 50 watts in a 50-ohm circuit. By 50-ohm circuit, I mean a 50-ohm antenna system at 1:1 SWR (higher SWRs are not 50 ohms), or a 50-ohm dummy load. Assuming the resistor in your RF probe is sized to match your DC Voltmeter’s input impedance (as explained above), you will get quite reasonably accurate measurements using the following formula:

rfprobe5

For example, I want to measure the power out of my TenTec 1340 40-Meter QRP transceiver. I place it on a 50-ohm dummy load, and key down. I generally use a BNC-Tee adapter to gain access to the output line, but I could as easily pop the cover off. Using the RF probe (alligator clip to chassis ground), I measure 12.2 Volts (DC) (and the same RF RMS Volts). Plugging this into the formula above I have PWR= (12.2 + 0.25) * (12.2 + 0.25) / 50 = 3.1 Watts. The rated power for this rig is 3 Watts, so I’ve verified everything is hunky-dorey.

We’ve added the potential barrier to the measured voltage above, but that little trick doesn’t work so well when you get down around a volt, and for voltages less than about a volt, the measurement accuracy suffers greatly. Also, the diode’s response is severely non-linear below the barrier potential, and will generally read much less than expected in circuits where the RF voltage is less than 1/4 volt. So if you see tiny readings in circuits where it’s normal to have voltages less than 1/4 volt RF, don’t get too spun-up about the low readings… it may mean everything is normal. My rule of thumb for guessing at this is as follows: For collector/drain circuits in oscillators or transmit-chain amplifiers in key-down, expect RF Voltages about 20-50% of the applied DC (supply) voltage. This depends on the circuitry, of course, but it’s a reasonable gesstimate. Base/gate and emitter/source circuits will generally be much less, maybe 5-10%. Circuit impedance will affect this too.

HamRadio360 – Workbench Mini PowerPole Power Strip PCB

I finally got to meet and shake hands with the HamRadio360 gang in person at Dayton Hamvention 2017- Cale K4CDN, Jeremy KF7IJZ and George KJ6VU

One of the kit pcb’s I picked up was the PowerPole Power Strip

More details at http://hamradio360.com/index.php/workbench/

These guys have a fantastic builders and non-appliance operator  podcast in conjunction with Cale’s excellent show.

Takes 15 minutes to build but super useful

I bought the Anderson Poles from the good people at Debco that also had a booth at the show

Happy Building and melting some solder

NOTE: in the hurry to get the PCB ready for Dayton Hamvention the 4 mounting holes will short out if metal screws and a metal cabinet are used. Use plastic screws. I ran some velcro on mine so i can affix it to various field rigs and power units
