Gerry Thomas of Radio Plus is Silent Key

I’ve just learned via Paul (N0CTF) that Gerry Thomas of Radiosplus passed away on June 19, 2020. Many of you are likely familiar with Gerry’s excellent antennas and accessories, especially the Quantum Loop series and Q-Stick.

Gerry was always very kind to work with and obviously a very talented engineer.

He will certainly be missed.

Listener Post: Mike Stutzer’s love of radio began with a Hallicrafters S-120

Many thanks to SWLing Post contributor, Mike Stutzer, who recently shared the following listener post:

I started SWLing as a teenager. My favorite uncle gave me a Hallicrafters S-120.

My dad hung a longwire under an eave and through a casement window frame into my bedroom. I marveled at all the AM international stations broadcasting in English, listening to everything from BBC cricket coverage on Saturday morning to hysterically unbelievable Albanian political news coverage.

After college I could afford something better, so I upgraded to a “boat anchor” Hallicrafters SX 110. It had a useful crystal filter to improve selectivity, but it was still nigh on impossible to decipher a Ham on SSB.

Many decades later I bought a house on a steep foothill. Realizing that it was a perfect QTH for a Ham station, I got licensed and now am President of the local ARC. Here is a loving look at the original SWL receiver that got me hooked.

Reminder: Help record the 2020 BBC Antarctic Midwinter Broadcast today (June 21)

Every year, the BBC broadcasts a special program to the scientists and support staff in the British Antarctic Survey Team. The BBC plays music requests and sends special messages to the small team of 40+ located at various Antarctic research stations. Each year, the thirty minute show is guaranteed to be quirky, nostalgic, and certainly a DX-worthy catch!

After successful listener events from years past, I’m once again calling on all SWLing Post readers and shortwave radio listeners to make a short recording (say, 30-60 seconds) of the BBC Antarctic Midwinter Broadcast today and share it here at the Post.

Important: Time and frequencies

There has been some confusion about the broadcast time.

Trusted DXers have reported the time as 21:30 UTC–this is the time when the broadcast has taken place in years past, no doubt coinciding with events at the BAS bases in Antarctica.

The BBC website has reported the broadcast time as 21:30 BST which would equate to 20:30 UTC.

I will listen at both times, but perhaps this is when the BBC are to broadcast the stream online? Likely a mistake on their part.

Many thanks to SWLing Post contributor, Richard Langley, who confirms the three frequencies the BBC plan to use this year:

  • 5790 kHz from Woofferton UK
  • 7360 kHz from Woofferton UK
  • 9580 kHz from Ascension Island

Recording the Midwinter Broadcast has become an SWLing Post community tradition! Read our previous post for more details. We will also publish a reminder on June 21, prior to the broadcast.

I’m especially fond of this broadcast as it always falls on my birthday and–this year–Father’s day as well!

If you would like to participate in our BBC Antarctic Midwinter Broadcast recording event, please read our original post which includes all relevant details.

Building the EA3GCY DB4020 Dual-band 40 and 20M QRP SSB Transceiver Kit (Part 1)

Many thanks to SWLing Post contributor, Frank (ON6UU), who shares the following guest post:


Building EA3GCY’s DB4020 QRP Transceiver kit

by Frank Lagaet (ON6UU)

In May, I discovered via a newsletter that a new kit was available from Javier EA3GCY in Spain.  I was immediately sold as this was a kit from my favourite kit producer and it has 2 bands–it will also be able to do CW and there also will be a CW filter.

After building 2 MFT’s from Javier which work without problems, I needed to have the DB4020.  The MFT’s are for 20 and 40 mtrs and do DSB (double side band).  I did put them in a not-so-graceful box but they do what they are intended for which is QRP phone (SSB).   They came together without problems so I expected the same for the DB4020–I knew for sure when I saw the board:  all through-hole components (except for some capacitors which are factory soldered) and a lot of space on the board.   The board has been silk-screened with clear indications on where all components have to come and the manual has very clear instructions where each component has to be soldered with referral to a quadrant.  The manual provides a 252 quadrant page so it is a piece of cake to find where each piece goes.

What do you get?

Javier provides you with all components which need to be installed on the board and, of course, the kit board.  The components come in small marked plastic bags and all is well-wrapped up in bubble wrap.  The board is wrapped separately and that is put together with the component wrap which is then again wrapped up in bubble plastic.  All goes into an envelope.  Very well packed I must say.

Here’s a picture of the bags with components:

The silk-screened board:

I started with the resistors since that’s the easiest way. After that, I did the capacitors.  I like to solder in all flat components first, so next were the diodes and IC sockets followed by the elco’s.  The transistors were next together with all relays.  As you solder in the transistors one also has to mount the cooling heatsinks,  these cooling sinks are high and are ideal to protect the coils one has to make,  they also protect the polystyrene caps (which I always find vulnerable) when the board is upside down.

Many kit builders are afraid of winding the toroids in kits–don’t be!  It is easy.  Just take your time and follow the instructions given by Javier in the construction manual.  In this kit the builder has to wind 8 toroids:  6 are a single wire which goes through the toroid body,  1 is a toroid with 2 different windings, and 1 has a twisted pair which goes through the final toroid.  Be sure to measure the wire you need per toroid as instructed in the manual.  Javier gives some spare, so you can be sure.  You will also see that on next picture where the legs of the toroids have not been trimmed yet.  Once done I still had some centimetres of wire leftover.

Picture of the toroids ready to be soldered in:

Finally all other parts and pin headers went in,  jumpers were immediately put on where needed.

As I’m using a military-grade plastic box, I have to break-out some components like the display,  tuning encoder,  volume and rx control from the board.  I also have put an on/off switch on the box and already have the CW KEY connector ready installed. I also installed a loudspeaker in the box.  The SI5351 board and the Ardiuno Nano are the final components which go into the board after installing all wires.

Picture of the board:

I intend to attach a CW paddle to the box made out of a relay.  A HWEF tuner (from EA3GCY) which I was planning to incorporate in the box is I think a bit overkill. That HWEF tuner is already in a nice little box and would be a pity to dismantle,  also I’m running out of space in the box…  Maybe I can fit in a 9-1unun which would then give me good results on both bands…?

Maybe I will install a battery pack in the same box.

The box with board installed:

The box completed front side:

Mind you,  it still needs some additional switches for the CW part of the transceiver.

Brilliant, Frank! I really appreciate the video as well–sounds like the kit produces smooth audio and should serve you well. No doubt, that military box enclosure will survive even the roughest field conditions!

Radio Waves: Chelmsford Radio at 100 Years, First Broadcast Station Site, Alfred Vail, and News Executives Purged from VOA

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!

Many thanks to SWLing Post contributors John Hoad, Bruce Atchison, and David Korchin for the following tips:


Chelmsford celebrates 100 years of radio with a play (Radio Today)

The city of Chelmsford is celebrating its status as ‘the birthplace of radio’ 100 years ago today with a special live stream of a new play about the Marconi Company tests of 1920.

Britain’s first ever radio entertainment broadcast took place on 15 June 1920, and featured two arias by Australian operatic tenor Dame Nellie Melba, one of most famous singers of the late Victoria era. The broadcast from the Marconi Factory was heard all over Europe and picked up as far away as Canada.

To mark the milestone, Chelmsford City Theatre is streaming a radio play The Power Behind the Microphone: The First Live Radio Entertainment Broadcast about the original broadcast, 100 years to the minute at 7.10pm this evening. International opera star Anna Steiger will recreate the concert given by Madame Melba as part of a radio play based on the story of that fateful night and the breakthroughs that made it possible.[]

Site of the World’s First Radio Broadcasting Station (Atlas Obscura)

Three plaques mark the spot where the “forgotten father of broadcasting” worked.

CHARLES “DOC” HERROLD WAS A pioneer. After founding his College of Engineering and Wireless in 1909 inside the Garden City Bank building at 50 West San Fernando Street in San Jose, California, he launched the world’s first radio broadcasting station, which beamed music, news, and notably, advertising to listeners on a regular basis.

Herrold and his team at Station FN, which included his own wife, the world’s first female disc jockey, epitomized the mantra of many a Silicon Valley startup today: “move fast and break things.” His early transmitting devices burned out one after the other, and Herrold had to use a water-cooled microphone. He stole wattage from San Jose’s street car line to power his innovative “Arc Fone” transmitter, and cut a deal with a local store to play records on a Victrola that he would point at the microphone.[]

Morse’s Partner Argued He Invented Famous Code—to No A-Vail (HistoryNet.com)

Alfred Vail came up with dots and dashes, but Patent Office gave credit to Samuel Morse, the better known inventor

In 1887, 18 years after his father’s death, Stephen Vail took up metaphorical arms to claim Alfred Vail’s place as a key figure in communications history. Starting a war of words that would last decades and end with a declaration carved into stone, the younger Vail bombarded newspaper editors with letters. Alfred Vail’s son insisted that his dad had invented the dot-and-dash system used in telegraphy and known to all, and most gallingly to the younger man, as “Morse” code.

Before telegraphy, the United States had been more a collection of outposts than a nation—when a treaty ended the War of 1812, word from peace talks in Europe between Britain and the United States took so long to creep across the Atlantic that two weeks after the signatures on the peace treaty had dried British and American troops were fighting the Battle of New Orleans. Until telegraphy arrived for good in 1844, information traveled no faster than horses could gallop, trains could roll, or ships could sail. News from Boston reached San Francisco and vice versa by traveling aboard vessels that had to round South America’s southern tip. Only dreamers spoke of rails crossing North America or a canal traversing the Isthmus of Panama. []

Trump administration purges news execs from U.S. agency meant to counter disinformation, leaving staff fearing more to come (CBS News)

The overnight purge of top news organization officials at the US Agency for Global Media (USAGM) has raised concern among its federal government employees and reporters that their jobs, immigration status, and editorial independence may soon be at risk following the arrival of new CEO Michael Pack.

Pack, who is a conservative filmmaker and close ally of one-time Trump adviser Steve Bannon, and had just stepped into the job after being confirmed by the Republican-led Senate earlier this month, did not respond to a request by CBS News for comment or explanation.

“Pack uses deep state language. Is Bannon calling the shots?”

A USAGM source said this is the question being pondered by executives and journalists inside the organization now.

Four news division heads were removed from their positions, including Middle East Broadcasting Network chief Alberto Fernandez, who is a former US Ambassador, Radio Free Asia’s Bay Fang, Emilio Vazquez of the office of Cuba Broadcasting, and Radio Liberty’s Jamie Fly. Replacements have yet to be named.

Steve Capus, the former CBS and NBC News executive who had been serving as a senior advisor, was also dismissed. Earlier this week, the top director and deputy director at Voice of America resigned as did the head of the Open Technology Fund Libby Liu, which promotes global internet freedoms.[]
