Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


Turkey demands Deutsche Welle, VOA and Euronews apply for a licence (Broadband TV News)

Turkish media regulator RTÜK has given three international broadcasters 72 hours to apply for a licence or have their online content blocked.

Voice of America (VOA), Deutsche Welle (DW) and Euronews are including video on their websites and are seen as among the few independent news sources still available in Turkey.

RTÜK published a statement on its website Monday, signalling the start of the 72 hour period.

If the procedure for applying for a licence is underway, a broadcaster can continue on-air for another three months, providing the anticipated licence fee is paid to the regulator in advance. [Continue reading…]

Finding MH370: New breakthrough could finally solve missing flight mystery (60 Minutes Australia via YouTube)

Is the biggest aviation mystery of all time, the disappearance of Malaysia Airlines flight MH370, about to be solved? Yes, if you believe the man you’re about to meet. Richard Godfrey is no crackpot; he’s a respected British aerospace engineer and physicist who says he’s found the doomed airliner. If he’s right, he’ll provide desperately needed answers for the families of the 239 passengers and crew who were aboard the Boeing triple-seven when it vanished eight years ago. But knowing where it is isn’t the end of the story – Richard also has to convince authorities to resume the search that’s already cost hundreds of millions of dollars.

Retired electrical engineer, 85, has £15,000 collection of 200 antique radios that he has been building up for 50 years – including one of the oldest sets in the UK (The Daily Mail)

A grandfather-of-five has revealed his impressive antique radio and test instrument collection worth up to £15,000.

Richard Allan, a retired electrical engineer, has spent the last fifty years collecting antique transistor, valve and crystal sets and has now shown off his impressive collection of more than 200 pieces.

The 85-year-old from Norfolk, first fell in love with radios because of his father, Alexander William, who built his own transmitter and spoke to people all over the world through the airwaves.

In fact, Richard’s first – and favourite radio within his collection – is the one his father, a HAM, or amateur radio lover, played non-stop during World War II after purchasing in 1938.

Another notable piece within his collection is an E52b German military radio, captured in a vehicle at Foxhill, Bath, which was where his father worked in the Admiralty. [Continue reading…]

Joshuah says: “The Cross Country Wireless LAA++ amplifier rocks!”

Image Source: Cross Country Wireless

Many thanks to SWLing Post contributor, Joshuah, who writes:

Dear Thomas,

I recently dedicated some funding to rebuilding my shortwave listening station.

I had paid attention to new amplifiers  and became aware of some review data by an engineer at SDRPlay comparing amplifier performance that suggests the Cross Country Wireless amplifier, at a cost of only 80 dollars, had become a competitive design offering performance comparable to amplifiers costing 10 times that much.

I was hooked by the specific demonstrations showing that the LAA++ offered IMD characteristics more similar to a Wellbrook, with gain more similar to other high amplification designs. I had to have one.

I set up my station with the following components:

    • A used Icron Ranger 2304 USB over ethernet extender off eBay
    • A used Airspy Discovery off eBay
    • A Cross Country Wireless receiver protector(or similar ferrite + gas discharge diode isolator)
    • A custom ordered LAA++ amplifier from Cross Country Wireless built for 75 ohm with F connectors and a low pass filter at 14MHz
    • A power inserter from an W6LVP that wasn’t cutting the mustard
    • A pair of classic, solid transforming power adapter bricks
    • An unshielded ethernet cable
    • Some Fair-Rite ferrite snap ons with multiple turns

I obtained a weatherproof enclosure and some pex tubing and specialty cable glands and built an antenna housing. Inside the enclosure I mounted the amplifier, adding a large gauge copper wire for the antenna element, and used an affordable tri-shield RG11 with specialty connectors as the feedline for the antenna.

The antenna measures approximately a 2 meter diameter, and is mounted about 5 feet off the ground at the base of the antenna. It is located outside of a remote shed at the edge of my property, and the ethernet (alternatively, wireless repeating parabolic dish with router) mirrors the USB data back to the PC in my basement which serves as the shortwave receiving server host.

I have been overwhelmed both with the amount of new noise and new signal that this antenna picks up.

In shortwave, the other night, I was picking up stations around the world.

Tonight, I was able to very clearly make out CHLO. I am located in EM38, over 700 miles from the transmitter, which only operates at 250 watts during the night time.
I was also able to pick up some international NOAA NAVTEX alerts on 518kHz about a right whale slow zone in the Atlantic off the shore of New Jersey.

I would  highly recommend this antenna amplifier.

Yours sincerely,

Joshuah

Thank you so much, Joshuah, for allowing me to post your note here in the SWLing Post. I’m so glad you found such an affordable way to cobble together an effective antenna system to not only mitigate interference, but also afford you DX-worthy reception. 

I’ve only heard good comments about Cross Country Wireless as well. 

Again, thank you for sharing your impressions and details about your setup!

Jock shares: “A bit more about NOAA Weather Radio”

A bit more about NOAA Weather Radio

By Jock Elliott, KB2GOM

Okay, I’ll admit it: I’m a fan, an advocate, an evangelist for NOAA Weather Radio (NWR).

Why? Because, quite simply, if you live in the United States, it is one of the very best deals you are ever likely to get. NWR is the voice of the National Weather Service. It is the fastest and most reliable means of receiving alerts when hazardous weather approaches.

NWR includes more than 1000 transmitters, covering some or all of 50 states, adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands, and the U.S. Pacific Territories. Broadcasts are found in the VHF public service band at these seven frequencies (MHz): 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, and 162.550. Radios capable of receiving NWR signals may include consumer radios, ham radios, scanners, and dedicated weather radios.

For more information about coverage, check these:

NOAA Weather Radio is free. There are no commercials, you don’t have to wait for other programming to be completed to hear the weather forecast, and, because it is radio, you can listen and get a concise summary of what’s going on with the weather in your area while you are doing something else. Even better, the folks at the National Weather Service tell me that over 80 percent of the NWR transmitters have some form of backup or emergency power, many of which can continue to operate for 5-10 days while the main power is out. There is a wealth of information about NWR here: https://www.weather.gov/phi/nwrfaq scroll down to see details.

Why do you want a receiver that can hear NOAA Weather Radio? Short answer: because every state in the Union has some form of hazardous weather that could prove lethal. Early warning just might save your life.

In his excellent book Warnings – the true story of how science tamed the weather, Mike Smith points out how successful meteorology has been at saving lives. In the 1950s, with the beginning of the tornado warning system, the death rate from tornados was 1.5 deaths per million people. By 2009, the death rate was down to .068 deaths per million, a decrease or more than 95 percent. The investment weather radar, prediction techniques, and warning systems such as NWR has paid handsome dividends.

So what makes an NWR-capable radio good? First, sensitivity. Greater sensitivity increases the odds that the radio will be able to hear more NWR stations in your local area, which in turn raises the probability that you’ll be able to hear an NWR station with backup power when the lights go out.

Second, alert capability. An alert function – that is, the ability to put the radio in standby mode and have it automatically switch on when NWR transmits an alert tone is a great plus. You can go about your business, and the radio will wake up and alert you when you need to pay attention.

Third, advanced alert capability. Ideally, you would like to be alerted only when a hazard is close to your immediate vicinity. Some dedicated weather radios and advanced scanners offer Specific Area Message Encoding (SAME) that can be programmed by the user to only alarm for weather and other emergency events in specific, desired counties, thereby eliminating unwanted alerts for areas that are not of concern to the listener. In addition, some weather radios have a selectable alert option that can be programmed to alert only when certain hazard codes – ranging from Avalanche to Winter Storm Warning – have been selected by the user and are transmitted by the local NWR station.

With that in mind, here are some NWR-capable radios with which I have had personal experience. With each radio, I did a quick search from the same location to see how many local NWR stations it would receive, as a rough indication of sensitivity. The good news is that every single one of the radios below could receive at least two NWR stations in my local area and had basic alert capabilities.

Consumer radios with AM/FM receive

CC Skywave SSB

CCrane 2E –could hear clearly 3 NWR stations in my area, basic alert function, house mains and battery power (over 200 hours).

CCrane Skywave SSB – could hear 2 NWR stations clearly and one scratchy, basic alert function, battery power (over 50 hours).

Eton FRX3+ — could hear NWR 3 stations clearly, basic alert capability, power options include solar, hand-crank dynamo, and rechargeable battery (can also be recharged off house power with USB capable), internal battery can be used to recharge cell phone battery.

Ham radio hand-talkies

Icom V80 with aftermarket high-performance antenna – could hear 2 NWR stations clearly and one scratchy, basic alert capability.

Yaesu VX-6 with Diamond 77 aftermarket antenna — could hear 2 NWR stations clearly and one scratchy, basic alert capability.

Scanners

Uniden BC125AT with Diamond 77 aftermarket antenna – could hear 3 NWR stations clearly, basic alert function.

Uniden SDS200 with homebrew off-center-fed dipole antenna (see below) – could hear 6 NWR stations clearly, highly sophisticated programmable SAME and specific hazard alert functions, no battery power (the SDS100, handheld version of this scanner provides battery power); would require uninterruptible power supply or something similar if mains power goes off. Author’s note: while the performance is stellar, this is by far the most expensive option. With the stock antenna that comes with the SDS200, I could hear two NWR stations clearly.

Dedicated NOAA Weather Radio Receiver

Midland WR120 Weather Alert Radio – At the time I began this write-up, I did not own a dedicated weather radio receiver, so I reached out to www.midlandusa.com, and they were kind enough to send me this unit, which is built solely to receive National Weather Radio stations. With the built-in whip antenna extended, the receiver was clearly very sensitive. I could hear 4 of my local NWR stations clearly, and 2 more scratchy but copyable. If you are in a fringe area, there is a socket for plugging in an external antenna such as the one I describe below.

There is a little symbol on the box that says “EZ Progamming,” and I was pleasantly surprised that it was true. Between the MENU and SELECT keys, it is easy to walk through the setup. I thought that I would have to look up the SAME code for my location, but the WR120 has a built-in database of all the states and counties, so selecting my county was a snap. In addition to SAME programming, the WR120 has a long list of selectable alert options that you can choose to meet your needs. That list can be downloaded here: https://cdn.shopify.com/s/files/1/0531/2856/0817/files/SAME_List_of_Emergencies_Non-Weather_Emergencies.pdf?v=1636648846

The WR120 is powered by a tiny wall-wart transformer that plugs into house power, and the user installs 3 AA batteries to provide back-up power in case the lights go out. The manual does not say how long it will operate on battery power.

It seems to me that if you do not already own a device that will receive NOAA Weather Radio stations, the WR120 would be an excellent choice.

Boosting Performance

If you want to boost the performance of the radio you are using to listen to NOAA Weather Radio, I can highly recommend this antenna: https://wiki.radioreference.com/index.php/Homebrewed_Off-Center_Fed_Dipole .

I built the wire version, hung it inside in a corner of my radio shack, and with it attached to either Uniden scanner or my Icom V80 ham handi-talkie, I can hear six NWR stations from my location. This antenna offers a large boost in performance for a modest investment of time and money.

In his blog, Smith argues that each of us ought to have redundant means of alerting us to hazardous weather: an app on your smart phone, plus an NWR-capable radio with alert function at home, plus your local TV or radio stations. To which I say: darn good idea!
