Gayle Van Horn 

The annual release of the World Radio TV Handbook is always an anticipated event for worldwide radio listener’s, both the casual program listener, or an enthusiastic radio aficionado.

This year’s 73rd edition, begins with an editorial and preview by Nicholas Hardyman, Publisher. If you are in the market for a software-defined radio, two receivers will undoubtedly pique your interest. The recent release of WinRadio Excalibur Sigma has been awarded by WRTH as the best and most capable SDR on the market or perhaps the world.

If a budget-friendly hobby is required, consider the SDRPlay RSPDuro.In a lower price class, it was reviewed as a remarkable receiver for its functionality and would represent an excellent choice. Equally impressive is the review of the Airspy HF +, awarded Best Value in an SDR. Additional reviews include the Reuter RDR51 ‘Pocket’ receiver, and XHData D-808, an ‘ultra-portable’ radio, for its low-cost and small size AM and FM portable. Scanner fans in the market for a high-grade wideband hand-held scanning receiver, will find the Icom IC-R30 review, informative and recommended as a good contender to consider.

The Features section begins with HF Curtain Arrays. Written by former BBC Senior Transmitter Engineer, Dave Porter G4OYX, featuring a behind the scenes look at the history and development of classic HF broadcast antennas.

Freelance writer and active radio enthusiast, Hans Johnson, explores two radio stations entitled Broadcasting for Peace. Both stations, Dandal Kura Radio International, and Radio Ndarason International, share their goal to bring programming to a troubled region seeking peace.

YLE foreign news journalist and radio hobbyist Mike Mäkeläläinen, travels to the Marshall Islands national broadcaster, Radio Marshall Islands. The writer shares the latest from V7AB and the station’s future. Though a small station, Radio Marshall Islands transmits a very powerful voice which reaches far beyond the Pacific region.

A major new development in 2018, was the TWR Bonaire inauguration, as the most powerful radio station in the Western Hemisphere. Known as ‘Shine 800,’ the faith-based station broadcast from a new 440 kW transmitter. TWR Broadcast Engineer Dave Pedrsen outlines this massive project in the TWR Bonaire feature.

Closing the features section, is the annual round-up of digital broadcasting. This year’s edition investigates the distinctive characteristics of analogue and digital transmission systems. Predictions are that medium wave and FM broadcasting will remain viable to a world audience.

Ulf-Peter Hoppe, adjunct professor of physics, updates the annual HF Broadcasting Reception Conditions Expected During 2019. His predictions are for a good year of reception on the HF broadcasting bands.

The National Radio section includes domestic radio stations broadcasting to a national listening audience on medium wave, shortwave, FM and DAB. Listings are grouped by country and include frequencies, transmitter information, power kW, contact and website information.

The International Radio list the same information for international broadcasters, airing to a world listening audience.

Review: World Radio TV Handbook 2018


World Radio TV Handbook 2018 Review 
by Gayle Van Horn W4GVH
Teak Publishing

          As December nears each year, in addition to holiday activities, radio enthusiasts are reminded that the release of World Radio TV Handbook’s (WRTH) annual edition is also in our future. This year is not the exception. WRTH 2018 released their latest edition, to worldwide listeners during the latter part of December.

Nicholas Hardyman, Publisher, begins this edition with a brief synopsis of what is included in the book and some general comments. Equipment reviews follow, with a look at the ICOM IC-R8600, a wideband communications receiver, receiving rave reviews for it’s combination of a modern SDR (software defined radio), below 30 MHz coverage, and a conventional superheterodyne radio, referred to as “two separate receivers” in one.

Building on last year’s review of the SDRplay RSP, WRTH reviewed their new model known as SDRPlay RSP2. The newer receiver offers a considerably larger feature set and provides extended coverage down to one kHz. The reviewer notes, “the RSP2 is hugely impressive.”

Are you looking for a high-end portable radio? The Tecsun PL-880 is rated as Tecsun’s best product yet, owing to the excellent DSP filtering and good audio. In contrast, is the Tecsun S-8800, a larger, though considerably different transportable radio. An additional review of the AOR AR-DV10, a hand-held battery-powered scanning receiver, popular among scanner hobbyist is also included.

Antennas play a large role in your radio reception, and the Cross Country Wireless Active Loop, appears to be an answer to many antenna issues. The testers conducted test-runs both indoor and outdoor. The Cross Country Wireless loop is noted for its ease of assembly and disassembly, as well as being an asset for those faced with limited space for antennas.

Another SDR review in this edition was the Expert Electronics ColibriNano It gathered favorable attention from the WRTH reviewers. The Nano offers a bandwidth of 10 kHz-55 MHz, and can be extended to 500MHz with an external filter. Overall, the Nano received good reviews, comparable with the lower-cost RSP2.

In the features section, well-known New Zealand DXer, Bryan Clark, takes readers on an Antipodean Journey to Spain and Morocco. An antipodean consists of two places situated diametrically opposite to one another on the earth’s surface. Using this as a radio perspective, Bryan focused on his long-held fascination for this part of the world and the radio-scenes for medium wave and shortwave.

Freelance writer and active radio enthusiast Han’s Johnson latest journey, takes him to Radio Romania International in Bucharest. The station’s long history has covered the ravages of war and communist dictatorship to the vast broadcasting improvements of today. Radio Romania International retain a large multilingual voice to the world with big plans.

Has the issue of noise and interference continued to plague your listening area? The WRTH editorial staff revisits the subject and delves in-depth on issues of concerns voiced by reader feedback. Since noise and interference continue as an increasing problem, the WRTH staff has a few ideas to consider in combating it.

In March 2017, Voice of Hope, the first and only Christian radio station in Israel, began broadcasting on mediumwave 1287 kHz. Because of its mission and powerful coverage, the station is well-placed to reach their Arabic programming into Cyprus, Jordan, Lebanon and Syria, with nighttime coverage into areas of Egypt and Turkey. Founder and President of the Strategic Communications Group, John Tayloe describes setting up a new medium wave station on the southern shore of the Sea of Galilee.

Radio nostalgic fans will enjoy Dr. Martin Hadlow’s feature on exploring the history of broadcasting in Radio Voices from the South Seas. From the new ‘technology’ of 1923, perils of WWII, and present day international regulations, Solomon Islands Broadcasting Corporation remains a critically important role to listeners in the South Seas and beyond.

DRM (Digital Radio Mondiale) began as an experiment, with predictions as a major advancement in broadcasting, but has not by many observers, ‘caught-on’ with world listeners. Is there any future for this mode in this year’s feature Digital Update?

Ulf-Peter, adjunct professor of physics, updates his annual HF Broadcasting Reception Conditions Expected During 2018. During the year, he predicts a good year for reception on the HF broadcasting bands, recommending an excellent time for newcomers to join the radio hobby.

The National Radio section includes domestic radio stations broadcasting to a national audience on medium wave, shortwave, FM and DAB. Listings are grouped by country and include frequencies, transmitter information, power, contact and website information. The International Radio contains the same information for international broadcasters airing to a world audience.

Clandestine and Other Target Broadcast, contain stations broadcasting politically motivated programming, or those targeted at zones of local or regional conflicts. A one-page listing of Religious Broadcasters Cross Reference Table closes this section.

The Frequency List, covers by-frequency listing of world medium wave stations. The SW Stations of the World includes a by-frequency listing, followed by International Broadcasts in English, French, German, Portuguese and Spanish in UTC 24-hour format. DRM International Broadcasts is arranged by UTC hour. Closing this section is National Television listings
by country.

This edition ends with an extensive Reference section of country indexes and codes, world transmitting sites, radio clubs, organizations and institutes, selected Internet resources, WRTH abbreviations and symbols plus Transmitter Sites (location and decode Tables) for international transmitter sites, Domestic SW Transmitter Sites, Standard Time & Frequency Transmissions contain contact information and schedules for worldwide time and frequency stations.

The World Radio TV Handbook, 72nd edition, remains a gold-standard reference book for the global broadcasting audience. It still is the most comprehensive guide to broadcasting and a must reference in every radio listening-post. I highly recommend this excellent publication.
