WRTH 2021: A look inside the 75th Anniversary Edition!

Last week, I received a long-awaited Christmas gift: the 2021 World Radio TV Handbook. Normally, I’d receive this annual guide in the December time frame, but because of delays in international postal services due to the Covid-19 pandemic, I took delivery a few weeks late.  

I always look forward to receiving this excellent staple radio reference guide–and this is their 75th edition! As I say each year, the WRTH has never disappointed, so my expectations are always quite high.

Once again, the WRTH lived up to my expectations.

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

The first article always features a WRTH contributor:  this year, they feature Stig Hartvig Nielson. His path to becoming a WRTH contributor began in his childhood when he said he was “tall enough to reach the radio tuning knob and tune away from dull Radio Denmark.”  His love of radio lead him down the path of becoming a broadcaster. Many of us know him via his station, Radio208.

WRTH Reviews

The second set of articles is always my favorite: WRTH receiver reviews.

This year, WRTH begins with an in-depth review of the AOR AR5700D wideband communications receiver–a radio I’d likely never touch in real-life, so it’s wonderful to take such a deep dive.  Next up is a review of the Bonito NTi MegaDipol MD300DX antenna which gets high marks for high gain, low noise, and good dynamic range. The following in-depth review is of the benchmark Icom IC-7610 general coverage transceiver. This was the first time I’ve read a review of this SDR transceiver with radio listeners in mind. WRTH then review the Bonito NTi CCMC30 common mode noise filter–a tool that can help radio enthusiasts mitigate RFI.

A review of the SDRplay RSPdx follows and the review speaks to the performance improvements included with the new HDR mode. The next review is actually one I authored of the Tecsun PL-990 portable radio–it’s always an honor to be in the pages of the WRTH!

The final review is of the Valent F(x) KiwiSDR; a little web-connected SDR receiver that has certainly transformed the nature and accessibility of remote listening.

WRTH Features

The first feature article, written by none other than Dave Porter, focuses on the development of HF broadcast transmitters. This article adds to the one he authored last year which focused on broadcast antennas. Dave is amazing because he has such an extensive history in the world of HF broadcasting and his experience and expertise are obvious in all of his writing. This is a must-read for those who want to know more about the “business side” of an international broadcast signal!

Manfred Rippich’s feature, Radio in Bhutan, explores the story of broadcasting in one of the most mountainous countries in the world where communities–including the capitol–are not easily accessible. Radio broadcasting plays an important role in this amazing country.

The following feature, Coastwatchers & the AWA Teleradio 3BZ written by Dr Martin Hadlow, takes a look at the importance of portable radios in the Pacific War. An absolutely fascinating piece for those of us who love radio history.

The final feature was written by Alan Pennington and explores the dynamic Scandinavian Weekend Radio.  It’s hard to believe SWR has celebrated 20 years on the air as of 2020. Pennington’s article explores the grassroots energy of this unique broadcaster!

The final article–a tradition–is the WRTH  HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read especially as we continue to work our way out of a long-term solar slump.

The 75th is another fantastic edition of the World Radio TV Handbook. As I say every year, I’ve never been disappointed with WRTH. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2020 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) , Amazon.com (US),  or the Book Depository (international).

Any experience with the Tecsun TU-80 enthusiast-grade FM tuner?

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

Hi Thomas -I hope you’re keeping well.

[…]I have had my eye on the Tecsun TU-80. However, I seem to find no videos on its use and no reviews. Perhaps it’s because it’s new.

I wonder if any of the SWLing Post readers have some info about it.

Post readers: If you have any experience using the Tecsun TU-80 FM tuner, please comment. I am not familiar with it. Very curious if it might be a great dedicated FM DXing receiver. It is pricey ($530 US on eBay).

An update from Radio Kahuzi

Drawing of the new studio building for Radio Kahuzi

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

SWLing Post readers have no doubt been wondering, along with the rest of us, about the status of Radio Kahuzi, the religious missionary station in Democratic Republic of Congo.

The station has been off the air for months, following a lightning strike in 2020 and various ongoing problems with power supply there in DRC.

Now, a note from Richard McDonald, founder of Radio Kahuzi, who says that they hope to be back on the air soon, though no timeline is provided.

For those who are not familiar with the station, it used a slightly off frequency of 6210.2 kHz in the 48 meter band. This was within the area of European pirate stations, and various broadcasters transmitting to North Korea and Iran, but propagation was usually such that Radio Kahuzi could be heard at European SDR sites in the hour or so before station sign off in the 1800 to 1820 UTC range.

Unclear from the note sent by McDonald is what power the station will be using when it does
finally return to the air. Previously power was in the 500 to 750 watt range. McDonald provided a drawing of what appears to be the new studio building for Radio Kahuzi [see image at top of page].

Hi Daniel and our faithful Dxers !

Thank you for your interest and encouragement for Radio Kahuzi and BESI ! The Lord is GOOD and we are recovering from the malaria and the yearly flu; finding another Normal !

We received the repair parts Monday 1 Feb 2021 DHL from Mike Axmon and Son Set Solutions that we were not able to find locally, to repair our SW Transmitter, after a Lightning Strike that took out four Radio Stations the same day.

We hope the partial repair will now be complete to bring back the functions that thus far were uncontrolled after initially replacing the six transistors, etc. !

At the same time, SNEL is being converted to a Cash Power system at the Studio, and our Antenna will be re positioned Next Door.

A New Prime Minister will be installed soon, as the government is being transitioned, while we are all still in Lock Down with little changes being made backward and forward, locally and world-wide !

We trust you are all well and making progress where ever you are !

Keep Looking UP !

In His Love and Care,

Richard and Kathy McDonald, Directors

BESI / Radio Kahuzi / Bukavu, D R Congo

Many thanks, Dan, for the update!

Video: How the UK shipping forecast is made

Many thanks to SWLing Post contributor, David (G4EDR), who writes:

I know that you and many of your readers of the SWLing Post (myself included) have a fascination with the UK Shipping Forecast so thought you may be interested in this YouTube video showing how the Met Office prepare the forecast for broadcasting.

Thank you, David! Yes, indeed, I love the shipping forecast. I must admit that I’m pleased (and not terribly surprised) to see that forecasts are not based purely on computer models, but on the expertise of experienced meteorologists.

Thank you for sharing!

Listen to a live ARISS contact on Friday, February 2021

The number of ARISS (Amateur Radio on the International Space Station) has been lower during the Covid-19 pandemic due to so many schools being closed and relying on remote instruction. Many thanks to SWLing Post contributor, Bruce Atchison, who notes that there will be an ARISS contact tomorrow (February 5, 2021) in Canada.

Listening to an ARISS contact is actually quite easy as long as you’re within the footprint of the ISS during the pass. Almost any radio–a scanner, handheld radio, etc.–that can receive 145.8 MHz can tune in. Click here to read a previous post describing how to listen.

Check out the RAC news item below with full details:

ARISS contact with Ottawa Carleton Virtual Online School: Friday, February 5

Ottawa, Ontario

ARISS Event: February 5, 2021 – As part of the Amateur Radio on the International Space Station (ARISS) program, NASA Astronaut Mike Hopkins, KF5LJG, will connect with students from the Ottawa Carleton Virtual Online School in Ottawa, Ontario  and answer their questions (see below), live from the International Space Station (ISS).

The ISS call sign is scheduled to be NA1SS event and the will take place on Friday, February 5, 2021 at 17:41:04 UTC 40 deg via AB1OC. It is recommended that you start listening approximately 10 minutes before this time.

The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and AB10C which is located in New Hampshire:

Ground Station Coordinates:
AB1OC New Hampshire Latitude 42.712N; Longitude 71.590W; Elevation 110m

The contact should be audible over the USA and Canada (Eastern regions) and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

Steve McFarlane, VE3TBD, ARISS Central and Northern Canada representative, is the Mentor for the event and Brian Jackson, VE6JBJ, ARISS Western Canada Mentor, is the Moderator.

ARISS is an international program aimed at inspiring students worldwide to pursue interests and careers in science, technology, engineering and mathematics (STEM) through Amateur Radio communications opportunities with the ISS crew.

Multipoint Telebridge Contact via Amateur Radio

As mentioned above, members will ask their questions to Astronaut Mike Hopkins, KF5LJG, via an adapted telebridge link which will use a multi-point system in which they are connected to the conference call centre from their own homes.

The concept requires three things:

  • the ARISS telebridge radio ground station – a satellite Amateur Radio station with special equipment that an ARISS team member uses for teleconferencing
  • the astronaut on the International Space Station using the ARISS Amateur Radio station
  • students at their homes here on Earth

The telebridge radio operator links to the astronaut at the ARISS radio mic, and each youth then connects from home via their telephones. Their families can listen along with school faculty and the public from home.

ARISS invites the public to view the livestream of the upcoming ARISS contact at: https://youtu.be/Ery1JYmk72o
