Since making it known to the world last weekend about the release of "Carrying on the Practical Way" from PW written by G3RJV since August 1996. That particular Blog was proved to be the most eye catching article I have written so far, with Hundreds of hits over the first couple of days of it's issue. I also guess the tills have been busy ringing down at Practical Wireless HQ, at one stage it was marked as SOLD OUT but they soon pressed the restock button and reset this. Does this mean I get a Christmas card from them this year, or George gets a few extra Royalties to help his pension along?

What it does prove though is what I have said before and made well known to PW several years ago, that the G3RJV's series is very popular, and well liked in our circles, and will always be the anchor for the Novice to find a good reference point and solid footing into our hobby. Another way of putting George's work, is like a fine Wine that matures with age, or a Matt Monro recording that never fades, that is of course if you appreciate Matt Monro?
 
I have now printed some of my missing early parts out and bound them up into a folder, allowing me to read it when I have a boring moment:




One or Two contacted me to ask if this will be available as a book? I just don't know, but judging by the intense interest of traffic, over to you Practical Wireless!

​D​iscovering Vintage Transistor Radios
By Michael Jack

Although today’s chips may house billions of transistors, the average consumer is not familiar with the term ‘transistor’ any longer. And, while all of our devices depend on transistors to this day, the pocket transistor radio was the first ubiquitous device to introduce the world to solid-state technology. Michael Jack takes us on a visual tour of the history of the transistor radio through beautiful examples of the art of transistor radio production. He also tells us how to spot potential finds and restore these solid-state gems.

Monitoring Joint Warrior 15/2 and Russian Air and Sea Activity
By Tony Roper

In October 2015 there was the second of the large-scale exercises that take place every year off the north and west coasts of Scotland under the exercise “Joint Warrior” name, as well as exercises involving ballistic missile defense ships that took part in Joint Warrior and which took place in the danger areas at sea, off the west coast of Scotland. Tony shows how to monitor these twice-yearly exercises as well as how to keep track of Russian air and sea activity involved in their activities in Syria, much of which is found on HF frequencies in SSB and CW.

RTL-SDR Dongle: Your Eye to the Wireless World
By Mario Filippi N2HUN

The RTL-SDR dongle has garnered much popularity over the last several years as an inexpensive and effective broadband receiver for the radio enthusiast. Now Mario shows us how the RTL-SDR can be pressed into serving in other ways: as a rudimentary piece of test equipment to explore those countless wireless devices that power our world and make life convenient. You can use it when restoring vintage radios, doing frequency analysis, antenna analysis and a host of troubleshooting activities you may never have thought of.

ATSC Off-Air Local TV: Doing it Right
By Mike Kohl

Part of his continuing series on cord-cutting, Mike shows us how to use online tools to find out what’s available in your area for Over-the-Air (OTA) TV reception; what antennas work best; when to use and not use antenna amplifiers and how to configure your OTA-TV system without needing to use an antenna rotator. What are the TV reception limits in the area in which you live? You can learn how to get the most out of OTA signals wherever you live without having to spend a fortune on equipment or for cable and satellite-TV subscriptions.

VHF and Above: Aurora Propagation
By Joe Lynch N6CL

If you have spent any time on HF you are somewhat familiar with the effects of aurora, particularly on 10 meters. Those watery sounding signals you may have heard are signals affected by aurora. However, those funny-sounding signals are only one small aspect of auroral propagation. This month Joe shows us how to anticipate aurora propagation by monitoring WWV broadcasts. He also takes a look at the interesting world of High Altitude Ballooning. Joe says, “There is nothing more exhilarating than watching a helium-filled balloon take off and then chasing it using the signals being transmitted from its payload!”

This is a very exciting episode of Linux in the Ham Shack for us. It's so special, that it's a double episode! That's right, it's like getting two episodes in one. Your hosts (one of them new to the program) discuss winter field day, WxBot, the origin of Debian Linux, SSTV using Linux, OpenSSH security concerns, solving the Rubik's Cube with Linux and a whole lot more. Hope you enjoy, and please welcome our new host!

This week we installed a new Yaesu Fusion DR-1X repeater at a very nice site in Central Illinois. One of the things I’m a big fan of is controlling supply power via the web. This ability to remotely control the repeater is great – even if the controller goes belly up, you can turn the entire system off or just remotely power cycle it. I’ve used the Digital Loggers data center type power strips before, but they are a bit expensive – over $100. So for this site, I used the Iot Relay – Enclosed High-power Power Relay for Arduino, Raspberry Pi, PIC or Wifi, Relay Shield also from Digital Loggers. At under $20 from Amazon, it’s a great deal. It’s a relay connected to four outlets, enclosed in a very nice plastic case. Hooked to a Raspberry Pi, this little box provides me the ability to power cycle or turn off any equipment via the web. How do I get the from the web to the remote repeater site? Well through AREDN ham mesh software running on 5GHz equipment of course!

Since I had an extra Raspberry Pi on the shelf, this quick hack made for a fun project. I’m also going to add a temperature and humidity sensor so that we can monitor the environmental conditions in the repeater building. Here’s a short 3 minute video I made explaining the code and the connections. Have fun! Put the Amateur back in Amateur Radio!

An engineer turned UFO researcher is hoping to launch a low-earth orbit CubeSat to search for evidence of extraterrestrial life. Canadian Dave Cote has assembled a seven-person team to design, fund, build and launch the project that he hopes will provide some answers about the origins of recent unidentified object sightings across the globe.

“We have had astronauts, military personnel, police officers and the former Defence Minister of Canada come forward stating that extraterrestrial UFOs are real, and that we are being visited,” says Cote. “How can this be ignored and brushed off as nonsense?” Concerned that the public isn’t getting straight answers, the group has turned to crowdsourcing the project on Kickstarter.

Measuring roughly the size of a shoebox, CubeSats can pack a lot of science equipment into a small space. They have also made satellite deployment much more affordable, in some cases costing less than the price of a lower-end automobile. Sites like CubeSatShop.com have taken much of the complexity out of ordering needed components.

Cote says they’re a “go for launch” already but are looking for more funding so they can pack it with as much science equipment as possible. They aim to include image, infrared, electromagnetic, and radiation sensors. This would give them the capability of not only verifying visual data, but also correlating it with other events such as electromagnetic and radioactive fluctuations.

The team plans to measure ionized radiation with a scintillation counter and two cameras will capture a near 360-degree view around the CubeSat. They plan to remove the infrared filters on the cameras to cover more of the visual range.

Cote hopes to use amateur radio frequencies to transmit the data back to earth and a worldwide network of ham volunteers to receive it.

“We are planning to use the ham frequencies to send data down from the CubeSat to earth in hex or datafax protocol,” says Cote. “From what we understand, we should be able to send a 100kB packet every few minutes and this will enable us to send image thumbnails from space, along with some basic EM data.”

While the details of the transmissions have yet to be determined, Cote hopes to assemble a worldwide team of hams willing to receive and log whatever data the satellite captures.

“We need help from the ham community, in capturing the data and relaying it to our site,” he says. “There will be a 15-minute window for download from the CubeSat, and then another volunteer would be needed for the next 15-minute time window.”

Cote is cautiously optimistic that the satellite will provide corroboration of UFO reports from eyewitnesses on Earth. But even if the satellite doesn’t capture evidence of faraway visitors, he’s hopeful that it will record interesting natural phenomenon like meteors and solar flares.

“We can only hope that those who would like to know the truth will step forward and help,” he says.
