Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares another example of his radio log art, this time for clandestine station, Republic of Yemen Radio.

Carlos notes:

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 Trevor R, Andrea Bornino, Wilbur Forcier, and the Southgate ARC for the following tips:

First radio transmission sent across the Atlantic Ocean (History.com)

Italian physicist and radio pioneer Guglielmo Marconi succeeds in sending the first radio transmission across the Atlantic Ocean, disproving detractors who told him that the curvature of the earth would limit transmission to 200 miles or less. The message–simply the Morse-code signal for the letter “s”–traveled more than 2,000 miles from Poldhu in Cornwall, England, to Newfoundland, Canada.

Born in Bologna, Italy, in 1874 to an Italian father and an Irish mother, Marconi studied physics and became interested in the transmission of radio waves after learning of the experiments of the German physicist Heinrich Hertz. He began his own experiments in Bologna beginning in 1894 and soon succeeded in sending a radio signal over a distance of 1.5 miles. Receiving little encouragement for his experiments in Italy, he went to England in 1896. He formed a wireless telegraph company and soon was sending transmissions from distances farther than 10 miles. In 1899, he succeeded in sending a transmission across the English Channel. That year, he also equipped two U.S. ships to report to New York newspapers on the progress of the America’s Cup yacht race. That successful endeavor aroused widespread interest in Marconi and his wireless company. Continue reading →

WRTH 2022: Two very important announcements…

15 Replies

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.

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 →
