Guest Post: Peter’s FM CB Update

Many thanks to SWLing Post contributor, Peter Laws, who shares the following guest post:


Thomas – Still Famous

by Peter Laws

We’re getting closer to the first legal FM CB on the market in the USA.  President Electronics  USA has announced that the President Thomas FCC CB radio will hit dealers in early 2022.

When first reporting on this, the assumption was that the Thomas FCC was going to be an FCC-spec Thomas ASC, a somewhat long in the tooth European multi-norm set.  As the release date has approached, and President has released marketing collateral, it’s apparent that this new product is, in fact, a rebranded President Barry II, a current-production state-of-the-CB-art AM/FM European multi-norm model.

Richard, G0OJF, a pipe organ restoration and two-way radio expert from Lincolnshire, England, runs a wonderful YouTube channel “UK FM CB radio servicing”, where he restores old UK-spec CBs and then tests them on air.  He also tunes up newly-released UK-spec CBs … and occasionally demonstrates restoration of 150-year-old pipe organs.  He recently covered the Barry II so if you are curious about the Thomas FCC you are strongly encouraged to watch his video about its European counterpart.

Your humble reporter, who, perhaps surprisingly, has not followed the CB radio market since, (checks notes), 1977 or so, was amazed to see that the MSRP will be $109.  In 1976 terms, that’s just under 25 bucks and had CBs been that price then, your reporter would have bought three because he’d been saving his pennies and that was the amount he’d saved!

Undoubtedly, the reduction in cost is from using components that are readily assembled by robots.  If you watch G0OJF’s video above, you’ll note that the unit is almost completely made of surface-mount components.  Remarkable.

Watch for dealers to begin offering these in the next few weeks.  Your reporter plans to buy one and will be hanging out on Channel 31 FM once it’s installed in his radio room.  Presumably, President (and other vendors) will be watching to see how these units sell in order to make plans for releasing other CBs that include FM.  An AM/FM/SSB CB would be quite versatile!

Let’s play a game:  Spot the differences!

WRTH 2022: Two very important announcements…

If you’ve been reading the SWLing Post for long, you’ll know that I’m a huge fan of the annual World Radio TV Handbook (WRTH). If you’re a fan of WRTH as well, I’ve got some good news and some…well…less than good news.

Good News: WRTH 2022 is Shipping!

The new 2022 edition of the WRTH has been printed and is shipping.

Purchase your copy of WRTH 2022 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) , Amazon.com (US),  or the Book Depository (international).

Bad News: WRTH 2022 will be the final edition by WRTH Publications

WRTH’s publisher, Nicholas Hardyman, shared the following announcement today:

Having produced this book for the past 24 years we are very sorry to announce that WRTH 2022 will be the final edition of World Radio TV Handbook produced and published by WRTH Publications. This was a hard decision to make and one we only made after a lot of discussion. We know that many people rely on WRTH and greatly enjoy getting the new edition every year. We realise that this news will be disappointing for many people.

We want to thank you all for your loyal support over the years.

I know this must have been a very difficult decision for the WRTH team. While it is disappointing news, I wish everyone at WRTH the very best. I’ve gotten to know this team, especially Nicholas, over the years and it’s been an honor to work with them and even write a few of their reviews.

What now?

I believe WRTH will maintain an online presence for years to come. I would encourage you to keep their website bookmarked. Of course, we’ll announce any changes or updates to the WRTH site.

My advice? Don’t hesitate to buy the 2022 Edition!

Seriously. I can’t tell you how many readers over the years have told me they regretted not purchasing the final edition of Passport to Worldband Radio when it was new. Many didn’t realize that particular year would be the final edition and missed the opportunity.

In this case, we now know the 2022 edition of the WRTH will be the last. We have to assume the company printed roughly the same amount of books that they did last year since the decision was made after the book had gone to print.

In other words, the supply will be similar to last year, but I predict demand will be much higher with readers knowing in advance that this is the final edition.

My advice would be that if you want the 2022 edition, I would bite the bullet now instead of waiting.

Purchase your copy of WRTH 2022 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) , Amazon.com (US),  or the Book Depository (international).

Again, here’s wishing everyone at WRTH Publishing the very best! Thank you for so many years of bringing our amazing international radio world into print.

Guest Post: Pavel’s Homebrew “Monster” Drain Pipe FSL Antenna


Many thanks to SWLing Post contributor, Pavel Kraus, for the following guest post:


Building a Drain Pipe FSL Antenna

by Pavel Kraus

Hi, I greet all DX fans and the entire SWLing Post community! I enjoy reading reading this blog and the diversity of contributions from our authors and contributors; many thanks from me for so much useful information.

The following are the construction notes of my FSL antenna, which I designed thanks to the suggestions of GaryDeBock, and other FSL designers.

The antenna is a classic design featuring 60 ferrite rods 200x 10 mm, which are placed on a plastic sewage pipe.

Pict 3: Pipe with ferrite rods and windings

Pict 4: Pipe with ferrite rods and windings

In addition, sewer pipe sections are used for the entire antenna cover. I assume that this material can be obtained in other countries as well. Continue reading

Dan compares the Chameleon CHA RXL to the Wellbrook and W6LVP Loops

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post and review:


Chameleon CHA-RXL:  Is This Pro-level Loop A Worthy Competitor To Wellbrook and W6LVP?

by Dan Robinson

At the end of summer 2021, I took up an offer from Chameleon to test and review their CHA – RXL loop antenna.  The company describes this as a “new design high-performance” LF, MF, and HF receive-only loop perfect for mobile RV and apartment situations and with low noise characteristics.

This is not a cheap antenna, like the Chinese-made MLA-30, but a heavy duty professionally-built unit designed to, as the old TIMEX watch commercial said, “take a licking and keep on ticking”.

Price for the CHA RXL is around $500, though the company dropped the price at to $382 – but only for the two section loop rather than the single piece antenna advertised on its site.

You can see the Chameleon on the company’s website here, but it’s also sold by Gigaparts, DX Engineering and other radio suppliers.  Chameleon lists features as:

Highly directional, balanced input preamplifier to eliminate environmental noise and ground loops, receives on new 2200m and 630m ham bands, flexible mounting and power options, and a stealthy [36 inch] Navy gray loop [that] fades into the background sky.

The built-in preamplifier, says Chameleon, “will enable clearer reception than many large horizontal wire or vertical antennas.”  Weight of the amplifier is given as 7 lbs.  The large pre-amp box is made of heavy metal, with a rubber gasket seal. Continue reading

Radio Preservation Task Force announces partnership with the Shortwave Radio Audio Archive and Radio Spectrum Archive

I’m honored to announce that the Shortwave Radio Audio Archive and the Radio Spectrum Archive are now partners of the Radio Preservation Task Force.

Click here to read the official press release.

To say that I’m enthused would be an understatement:  the Radio Preservation Task Force has, as of today, officially partnered with the Shortwave Radio Audio Archive and Radio Spectrum Archive.   

When I learned that the Library of Congress’s National Recording Preservation Board created the Radio Preservation Task Force (RPTF) in 2014, I became an enthusiastic contributor early on, having started a modest preservation project myself only a few years prior.  Then, a partnership like the one created today would have been one of dreams.

As many of you here know, I’m not only passionate about technologic innovations in our radio space, but also preserving our past.

Shortwave Radio Audio Archive

It was in 2012, in response to a round-table discussion at the Winter SWL Fest, that I created the Shortwave Radio Audio Archive (SRAA). Many of us in the radio community were concerned about the number of original, made-from-home, off-air shortwave radio recordings (airchecks) that we knew were in existence, yet were simply disappearing with the passage of time. We were well aware of members of our community who had either passed away or downsized, and many of their recordings––some of pivotal world events––were being tossed out by well-meaning loved ones or friends who simply didn’t understand their relevance. In addition, many of these recordings were captured on magnetic tape, which becomes brittle with time; we knew these recordings were literally turning to dust.  I felt I had to do something.  The SRAA was that something.

Fortunately for me, the SRAA’s mission has really resonated within our radio community. Today, we have thousands of off-air recordings, all freely available to everyone. The recordings can be downloaded directly from the archive, but many listeners simply subscribe to the SRAA Podcast and receive each recording automatically, as it is published.

Turns out, the archive also attracts the interest of individuals outside of our radio world including historians, musicians, and filmmakers. Indeed, the archive has even been reviewed in The Wire Magazine by a music critic as an audio resource for electronic musicians. At time of posting, the SRAA is the inspiration for artists in the latest Cities and Memory project Shortwave Transmissions.

The archive is not, nor has ever been, monetized; it has no commercial sponsorship, and is completely funded by its contributors. It is free and open to everyone.

I’m exceedingly grateful to our many contributors who continue to unearth absolutely amazing off-air recordings. Our SRAA contributors are true champions of preserving our radio heritage in a space that will long outlast us.  We’ve taken measures to ensure that multiple archivists have full access to the site, so its existence isn’t dependent on any one individual. We also actively seek organizations and educational institutions who can house redundant copies of the Archive.

And still it grows.

Radio Spectrum Archive

Compared with the SRAA, the Radio Spectrum Archive (RSA) is still in its infancy.  But it, too, is growing, and the reason for this steady and growth is the existence of its contributors and other supporters.

Of course, while audio recordings––like those in the SRAA––are relatively small (often between 2 – 120 MB), spectrum recordings are larger by orders of magnitude.

As you might imagine–even in 2021/2022–it is not a simple task to digitally archive and share/move 20GB to 2 TB collections. We are incredibly fortunate in that the Internet Archive supports the RSA and gives us valuable real estate on their servers to preserve and share recordings.

With time, this collection will grow and become a resource for everyone. Our hope is that we may even be able to built a web interface (much like those used by Web SDRs) to play back recordings without having to physically download them.

My wholehearted thanks…

Of course, none of this would have been possible without the many contributors from within our radio community. Thank you all so much for being a part of a movement that archives our amazing, and amazingly diverse, radio history. You have made this possible.

Finally, I’m so grateful to the Radio Preservation Task Force––not just for this empowering partnership and what it means to us today, but for the future potential it represents.  It’s clear that we’ve only just begun.

Thank you––thank you––thank you, all.
