Feed aggregator

.

SHEPHERDSTOWN, W. VA. — In late 2006 or thereabouts I was asked by a colleague to help him select an automation program to recommend to one of his client stations that was looking to automate its talk format. He presented me with literature from Arrakis Systems on the Digilink-Xtreme automation product. After thoroughly reading the literature and going online to investigate further, I was sold on the system.

We then commenced planning the installation and programming of the system. We of course got the satellite package since most satellite delivered programming was already provided with automation cues. I found the instruction manual to be complete and easy to understand. After some experience with the system I found it to be self-intuitive to program. I understand that the system continues to perform flawlessly at that station.

In 2008 I was asked to recommend an automation system to one of my clients and, of course, I recommended the Arrakis Digilink-Xtreme. Again as in the first installation, I was impressed as was the client, especially with the ability not only to automate their talk format but to automate pro baseball, pro and college football and basketball games and the ability to handle baseball rain delays without human assistance.

In 2016, I was asked by the folks at Shepherd University for a recommendation for an automation system to replace the existing system they had at WSHC(FM). I recommended the Arrakis Digilink-HD system because of the newer features included in the software.

The system was quite easy to install, just like Digilink-Xtreme and as easy to program. Fortunately, I was forward thinking and insisted that they order the package that included the Bridge Switcher, a hardware matrix box originally designed to interface with multiple satellite feeds. I figured WHSC should have the ability to place any of their three studios on air if need be. In 2017, they were able to make an arrangement with West Virginia Public Broadcasting to carry much of their programming.

In 2018 Arrakis Systems announced a new automation program called Apex that looked to be cost-effective, and offered more features than Digilink-HD and Xtreme. After talking to the company’s Melissa Freeman and Ben Palmer, I recommended to WSHC management that they transition to Apex. I am happy to say that Apex has been all it was supposed to be and more. The transition to Apex occurred in short order one afternoon while we aired programming from the satellite receiver through the studio console.

In less than an hour, we were back on the air with Apex software running the show.

Yes, we have had some minor problems arise from time to time. However, we have never been off the air due to an automation problem. When we have had an issue that we couldn’t resolve on our own, Arrakis Customer Support came to the rescue. I can’t brag enough about Arrakis Customer Support. They have been the nicest people to work with, extremely knowledgeable and in all ways very attentive to customer needs. Hats off to all the employees at Arrakis Systems.

The Society of Broadcast Engineers has announced that it has reached an agreement to provide spectrum coordination services for the Department of Defense in the 2025–2110 MHz/2 GHz range. That range is a slice of the Broadcast Auxiliary Service Spectrum. It also includes some civilian mobile,  military and other federal activities such as NASA communications.

The DoD is developing and deploying training systems that will be active in that range in a number of locations across the country. Since it is shared spectrum, the department wanted to avoid disruption of the services as well as disrupting civilian and commercial services also using that range.

That particular range is used by radio and TV stations, notably STLs/TLSes, auxiliary broadcasting such as translators, cable TV relays and more. After consultation with the SBE along with the National Association of Broadcasters the department has entered into an agreement with the SBE for the broadcast engineering association to provide nationwide frequency coordination services.

According to a release the SBE board of directors approved the agreement in April. The association has selected the broadcast consulting firm Technical Broadcast Solutions. Its principal is R.J. Russell, CPBE, a 20-year member of the SBE. He was most recently also SBE national vice president and chair of its Frequency Coordination Committee.

SBE President Jim Leifer said, “Part of the SBE’s mission is to create working alliances within the broadcast industry and with those who work in our space. Entering into this agreement serves to protect broadcaster’s use of spectrum and provides a needed service to our government. I am pleased that we are able to partner with the DoD’s prime contractor in this effort.”

A heavy monetary forfeiture in the amount of $15,000 has been laid at the doorstep of a Virginia AM station after a series of alleged public file violations.

The Federal Communications Commission said that Hubbard’s Advertising Agency Inc., which is licensee of station WLLL(AM) in Lynchburg, Va., violated two sections of FCC Rules by failing to prepare required quarterly issues/programs lists and failing to upload that information into the station’s online public inspection file (OPIF).

In response, the company said the oversite was not intentional. The company’s owner, 92-year-old Fletcher Hubbard, is not computer literate, the letter said, and did not understand how to access WLLL’s online pubic file “let alone how to upload documents to the file.”

The FCC recently reviewed its public inspection file rules, which state that commercial broadcast licensees must maintain a public inspection file that details community-oriented programs that the station has covered during a three-month period. That list must include a narrative of the issues that were addressed as well as the time, date, duration and title of each program. Those issues and program lists must then be placed in the station’s public file and be kept while the station’s license renewal application is being considered.

The filing system was modernized in 2016 when the commission voted to update the OPIF Rule so that all public inspection files were uploaded to an online database. As of March 1, 2018, all broadcast radio stations were required to post all public file material (except certain political file info) in that file.

As station WLLL began compiling information for its license renewal application, it answered “no” when asked if documents had been properly placed in the station’s public inspection file at the appropriate times.

“[Hubbard’s] adult children, who recently begun to assist him in the operation of the station, have searched for such issues and programs lists and were unable to find any,” the licensee said in an letter to the FCC. “Going forward the licensee’s children intend to make certain that the station complies with all FCC requirements including uploading issues and programs lists to the station’s public file when due.”

But the FCC expressed no inclination to be lenient. “Where such lapses occur, neither the negligent acts or omissions of station employees or agents, nor the subsequent remedial actions undertaken by the licensee, excuse or nullify a licensee’s rule violation,” the commission said in response.

The commission has established a base forfeiture amount of $10,000 for those stations that fail to maintain a public file and an additional $3,000 for failing to upload required information, although the commission has been known to adjust that forfeiture upward or downward after considering the gravity of the violation and any previous offenses.

The FCC decided that a $15,000 forfeiture was appropriate for the licensee’s failure to prepare and upload quarterly issues and programs lists — in part because the public file violations were “extensive and not remediable” and occurred across two successive license terms.

“Notwithstanding the licensee principal’s advanced age, it is a licensee’s responsibility to comply with commission rules,” the Media Bureau said.

But even though the licensee’s violations were deemed as “serious violations,” they do not rise to the point that the FCC decided to outright deny the station’s license renewal. The commission decided instead to approve a short-term license renewal to ensure the licensee complies with the public file rules moving forward.

As the FCC and other global organizations discuss the potential reallocation of C-band spectrum to assist with the deployment and performance of 5G technologies, the World Broadcasting Unions has released its official position on what any reallocation of the spectrum used for Fixed-Satellite Services would mean for TV and radio broadcasters around the world. In short, WBU believes it would be a significant issue.

“The recent regulatory inquiries by the U.S. Federal Communications Commission on the potential reallocation of some of the existing C-band downlink allocation (5G services) is a concern for the members of the WBU,” the organization’s position paper reads. “Given the ubiquitous use of C-band spectrum around the world and its potential to provide new services, such U.S. regulatory activity will likely be pursued by other administrations. Any subsequent proposals to globally harmonize the use of these frequencies above 3600 MHz for IMT, argued for on the basis of national reallocations, do not reflect the realities of global satellite service usage.”

[Read: NAB’s McFadden Warns Against Negotiating Available C-Band Spectrum]

Among the primary concerns of the WBU in the event of spectrum reallocation is the potential compromise of existing distribution and collection systems both domestically and internationally. It believes this could be particularly impactful in countries with equatorial geography and high rainfall, which often don’t have viable FSS spectrum alternatives to provide the same level of performance. WBU also contends that some direct-to-home services using C-band in these regions could be affected.

The WBU also worries that in the event of reallocation for the downlink C-band spectrum, the “twinned” uplink C-band frequencies may also be tapped at some point for reallocation.

“In all likelihood, harm will be done to existing C-band users and the solutions will compromise service reliability and increase the costs to the broadcast community,” WBU states.

“While improvements in satellite technology have made the use of C-band spectrum by broadcasters more efficient and effective for both content collection and distribution, there has been real C-band traffic growth over the years, which makes this spectrum crucial to broadcasters today as it was 50 years ago.”

The issue of media ownership is back in the headlines after a federal appeals court ruled that the Federal Communications Commission “overstepped” in its recent media ownership rule changes, failing adequately to consider the effect on women and racial minorities.

The decision by the Third Circuit Court of Appeals comes after a review of the FCC’s 2016 quadrennial review order on broadcast ownership rules.

Back in 2017, the commission voted along party lines to eliminate the ban on cross-ownership of newspaper and TV stations in major markets, to ease the process for media companies to buy additional TV stations in a market, to allow local stations to jointly sell advertising time, and to let companies buy additional radio stations in some markets.

But in a ruling Monday, the appeals said it would vacate and remand the bulk of the FCC’s actions, sending it back to the commission for further consideration.

Democratic FCC Commissioner Jessica Rosenworcel said the court was right to reject Republican-led attempts to loosen restrictions. “Media ownership matters because what we see on our screens says so much about who we are as individuals, as communities and as a nation,” she said. “But over my objection, the FCC has been busy dismantling the values embedded in its ownership policies. Today, the Third Circuit Court of Appeals agreed.”

The National Association of Broadcasters called the decision disappointing.

“The media marketplace has undergone massive changes over the past few decades, let alone since 2004,” said NAB Executive Vice President of Communications Dennis Wharton. “It’s shocking that the same panel of judges has supplanted Congress’ and an expert federal agency’s views with its own for more than 15 years.”

Commissioner Michael O’Rielly was of a similar mind and urged Chairman Pai and the Trump administration to take the case to the Supreme Court. “For too long, the U.S. Court of Appeals for the Third Circuit has abused the statute and defied common sense as it pertains to media ownership limitations. It is clear that no argument, formula or well-reasoned reform can satisfy the majority’s wrong-headed demands, guaranteeing the complete preservation of the broken and outdated status quo,” O’Rielly said in a statement. He called it “a classic case of judicial activism and legislating from the bench that further justifies the ongoing fight for reforming the judiciary.”

The ruling is the latest in a long-running series of skirmishes between the court and the commission.

FCC Chairman Ajit Pai today accused the court of blocking attempts to modernize regulations to match the “obvious realities” of the modern media marketplace.

“It’s become quite clear that there is no evidence or reasoning — newspapers going out of business, broadcast radio struggling, broadcast TV facing stiffer competition than ever — that will persuade them to change their minds,” he said in a statement, adding that the commission nevertheless plans to appeal.

Pai also noted dissenting views expressed by Judge Anthony Joseph Scirica.

Scirica said that while he joined his colleagues in their rejection of part of the order that relates to the FCC’s incubator program as well as parts that deal with the Local TV Rule, he does not share the conclusion that the current FCC orders are arbitrary and capricious.

“In my view, the FCC balanced competing policy goals and reasonably predicted the regulatory changes dictated by the broadcast markets’ competitive dynamics will be unlikely to harm ownership diversity,” Scirica said. “I would allow the rules to take effect and direct the FCC to evaluate their effects on women- and minority-broadcast ownership in its 2018 quadrennial review.”

That leaves the commission with a decision on how to proceed. The 2018 Quadrennial Review is underway, and that process relies upon much of the same analysis as the orders vacated by the court, said Commissioner Geoffrey Starks in a statement.

“The court here suggests that ‘new empirical research’ may be required to fully satisfy our rulemaking requirements,” he said. “I wholeheartedly agree. Needless to say, today’s decision will require us to go back to the drawing board.”

Don’t eviscerate EEO rules for broadcasters.

That’s part of the message to the FCC from a group of organizations that support equal employment opportunity rules.

The FCC invited comments on how to improve EEO enforcement in broadcasting. The Multicultural Media, Telecom and Internet Council submitted a set of five proposals on behalf of itself and 36 other organizations. But they emphatically argued against an idea put forth recently by a group of 82 broadcasters that would raise the current threshold at which EEO requirements kick in from five full-time employees to 50; the supporters told the FCC that this idea “would put an end to most broadcast EEO enforcement.”

“The 82 broadcasters declare that 50 employees is ‘the number regarded by the human resources profession as demarcating smaller from large for the purposes of hiring a human resources manager,’” the EEO supporters wrote.

[Read: 82 Broadcasters Want to Change the Definition of a Small Station]

“What the 82 broadcasters overlook is the fact that the amount of ‘paperwork’ the FCC requires that does not have to be done anyway as part of any business’ routine personnel functions requires far less time than a full-time employee’s 40 hours per week. In fact, it is exactly the same work that routine recruitment entails: maintaining an email list, hitting a key to send out job notices and posting the notices online — while also ensuring that the posts and job notices are widely accessible and that records of the postings are maintained in the (very rare) event of an FCC audit. This additional ‘burden’ requires more like 40 seconds per week than 40 hours per week.”

The EEO supporters argue that compliance is not arduous and that over five decades, “not a single broadcaster credibly claimed that it suffered any material financial hardship because of the need to comply with the EEO rule. Nor did any broadcaster ever claim that the rule was too dense for it to comprehend.”

They argue that few radio stations and only about half of all television stations employ more than 50 people full-time. “In several states, every radio and nearly every television station would be EEO-exempt. Nearly all noncommercial radio and television stations nationwide would be exempt.

The effect of exempting so many broadcasters from EEO compliance would be devastating, they wrote. “Many broadcast careers begin in small stations. Cutting off EEO protection at these points of entry would have a ripple effect on the rest of the industry. Large broadcasters that do not discriminate would have less diverse, and thus less talented pools of trained applicants from which to draw.”

Finally, they wrote, “the idea that a broadcaster of any size greater than ‘mom and pop’ should be exempt from EEO compliance is deeply flawed and troubling. Broadcast ownership is a privilege that necessarily includes EEO compliance; ownership coupled with nondiscrimination is not a ‘burden.’ Discrimination is a burden.”

The EEO supporters took no position on two other suggestions from the 82 broadcasters, one that would require online posting of all full-time job openings by all licensees of any size including those with fewer than the current threshold of five full-time employees, and another that would have EEO reports filed by “entities” cover entire markets, to avoid a practice by some broadcasters of creating several small entities, each with fewer than five employees.

The supporters listed five priorities of their own. They told the FCC that:

• EEO data should be gathered as necessary for research on industry trends and EEO program effectiveness.
• EEO data should be requested from licensees “found to have failed to engage in the broad recruitment (e.g., via internet postings) that is required by current FCC precedent.” They said that failure to do so means that a licensee recruited primarily by word of mouth, which “has been deemed to constitute a racially discriminatory scheme when performed from a homogeneous staff.”
• Renewal applications and EEO audits should include a certification that job postings occurred before hiring decisions were made; they said this certification is common in other industries.
• The FCC/EEOC Memorandum of Understanding should be updated to ensure that the FCC immediately audits employment units that receive EEOC probable cause determinations.
• And “the commission should open an inquiry … into the pattern of consistently very low representation of minorities in radio news.”

Among the organizations in the MMTC filing are the NAACP, National Urban League, American Indians in Film and Television, Japanese American Citizens League, League of United Latin American Citizens, LGBT Technology Partnership and Institute, and 30 other diversity-oriented organizations.

“Inasmuch as the FCC’s record on EEO enforcement has not been refreshed in detail since 2004, the 37 EEO supporters appreciate this long-awaited opportunity for the commission to complete the unfinished work from its 1998 proceeding on EEO enforcement,” they wrote.

Ken Beckwith is a field engineer with EMF based in Nebraska. Being a hands-on engineer, Ken has done his share of construction over the years. One of his projects was the construction of an octagonal-shaped AM loop EAS antenna using PVC pipe.

Fig. 1: The completed loop antenna.

Before you begin this project, check out the completed antenna, shown in Fig. 1. The visual will help you piece all the angled elbows and tees together.

Note that to improve the strength of the loop, Ken added a piece of conduit down its middle.

Construction starts with one tee, to which you attach two 4-inch pieces to the arms of the tee. The 2-1/4-inch piece attaches to the bottom of the tee. The 90-degree elbow attaches to the other end of the 2-1/4-inch piece, but save that step until later.

Two 45-degree elbows attach to the 4-inch pieces so they lay flat. This is so the “tail” of the tee is at 90 degrees, as shown in Fig. 2. The 9-1/2-inch pieces of PVC attach to the elbows next. Then, another set of elbows and another set of 9-1/2-inch pieces.

Fig. 2: Two elbows attach to the 4-inch pieces so they lay flat. The “tail” of the tee is at 90 degrees.

Continue with a third set of elbows, and the 9-1/2-inch pieces. Attach the 2-1/8-inch pieces to the last elbows. The “tee box” is connected to the 2-1/8-inch pieces, so the bottom of the tee sticks up parallel with the tee at the top of the antenna.

Attach the 23-1/4-inch piece to the 90-degree elbow, mentioned above, and then attach the other end of the elbow to the 2-1/4-inch piece on the top tee. Position it so the bottom end will connect to the remaining tee at the tee box.

Attach the 2-inch piece to the tail of the remaining tee, then connect it to the 23-1/4-inch piece so the 2-inch piece fits down into the bottom of the tee on the tee box, as shown in Fig. 3.

Fig. 3: The 2-inch piece fits down into the bottom of the tee on the “tee box.”

Attach the remaining piece of conduit to the other end of the tee, and attach the end cap to the end of that piece, to complete construction. Assemble the parts without glue, first. Once everything is fitted properly, use PVC cement to make a permanent bond.

After the glue is dry, fish a pull string through the conduit loop. A vacuum cleaner will make the job easier. Tie the Belden cable to the end of the pull string, and secure with electrical tape. Pull the cable through the pipe.

Strip the jacket off both ends of the cable and unwrap the shielding foil from each of the three pairs, and from both ends. Cut the shield wires off only one end of the cable. Join the ground wires at the other end together. Take the red wire next to the shields and lay it with the shields. It will be connected later. Take the other end of the red wire and connect it to the opposite end of the black wire paired with it. You’ll want to solder these connections, and cover them with a short piece of heat shrink or electrical tape. You will be making a six-turn coil using the multi-pair wires.

Now take the other end of that black wire, described above, and connect it to the white wire on the opposite side. The second end of the white wire connects to the black wire of the same pair at the first end. That black wire then connects to the green wire on the opposite side. The second end of the green wire then connects to the opposite end of the black wire it is paired with. The second end of the black wire connects to ground along with all of the shields.

Confusing? Fig. 4 gives you a visual of the connections.

Figs. 4a and 4b: A visual representation of the wiring connections to form a six-turn loop antenna, and a closeup identifying the wire colors.

Once the connections are made, connect the shields and the black wire from the opposite side to ground using a 3/8-inch ring connector. That is held in place using the nut securing the F connector barrel to the tee-box housing.

Fig. 5: All of the wiring connections, as well as the ground for the F-connector, are made in the tee-box.

The antenna has a broad coverage angle with a deep null when the antenna is broadside to the signal. Aim the “edge” of the loop toward the AM station you want to receive. The strongest signal will be received when the antenna end or edge is pointing to the signal source. The antenna can be mounted on a mast with U-bolts, hose clamps or whatever else works.

Here’s the construction parts list:

A 10-foot length of 3/4-inch diameter, schedule 40 PVC conduit cut into the following lengths:

2 – 4-inch
1 – 2-inch
1 – 2-1/4-inch
2 – 2-1/8-inch
6 – 9-1/2-inch
1 – 23-1/4-inch

Whatever is left over can be discarded, but before making your cuts, cut the flared end off, so all cuts are even.

1 –  3/4-inch 90 degree elbow
2 – 3/4-inch tee
8 – 3/4-inch 45 degree elbows
1 – 3/4-inch cap
1 – 3/4-inch tee box, plastic, with weatherproof gasket
1 – 7-foot piece of Belden 8777 or other three-pair shielded cable
3 – 7-foot single-pair shielded cables can substitute for Belden 8777

WOOFFERTON, England — Nestled in the beautiful Shropshire countryside, just a few miles from England’s border with Wales, is the tiny village of Woofferton. That name is synonymous with shortwave radio for millions of listeners around the world as just a short distance from the village itself, lays the United Kingdom’s last remaining public service shortwave transmitting station.

Antenna switches in the field feed the HF curtain arrays.

Now owned and operated by Encompass Digital Media, Woofferton recently celebrated its 75th birthday. Built in 1943, the station has a fascinating history; originally designed to bolster the BBC’s General Overseas Service (now the World Service) during the latter years of World War II, it was later partly funded by the United States and was used extensively by the Voice of America to broadcast into Eastern Europe and the former Soviet Union during the cold war years. Today, Woofferton transmits programs for the BBC and a number of other international broadcasters, reaching audiences across Europe, North Africa and the Middle East.

OPERATIONS

Woofferton near Ludlow in Shropshire is the U.K.’s last shortwave broadcasting station.

There are 10 high-power HF transmitters at Woofferton. They range from Marconi senders of various vintages, including two BD272 250 kW units that date back to the 1960s, to the more recent 300 kW B6124 solid-state transmitters, and four of the most modern RIZ 250K01 wideband systems, which are also capable of operating in Digital Radio Mondiale (DRM) mode. In fact, the BBC’s daily DRM transmission for Europe is broadcast from here.

Outside in the antenna field, there are 35 shortwave curtain arrays (aerials) supported by 25 masts. Most of the antennas can be operated in full or half-curtain mode, depending on the coverage required, and can be electronically steered (slewed) to beam transmissions in a variety of directions. This is done by varying the phase of the signal and feed points to the antenna, rather than by physical movement.

The Duty Room has visibility of all of the station’s transmission systems, and executive control of the broadcast schedule.

The Woofferton team numbers some 14 staff, comprising of broadcast engineers, maintenance technicians, mechanical and electrical engineers, riggers (antenna specialists) as well as providing an outpost for Encompass’ International Operations team. The station’s facilities and location make it an excellent logistical base for the testing, servicing and deployment of a wide range of satellite receivers and FM radio transmission systems which are installed at hundreds of BBC FM relays and partners around the world.

A Marconi BD272 250 kW sender, one the station’s oldest transmitters, is still in regular daily use.

Woofferton has one of most modern and flexible transmission control systems in the world, allowing the entire facility to be remotely controlled and monitored by Encompass’ MCR in London, over 150 miles away. At around 5 p.m. each evening, the Woofferton engineers handover control to the nightshift in London and until 8 a.m. the next morning, the whole operation is fully automated.

MCR engineers in London can take control at any time however and remotely power up and tune the transmitters and then switch the output to any of the available antennas in just a few minutes. This capability is particularly useful if another transmitter fails and an alternative resource is required at very short notice. This flexibility means that scheduled broadcasts from other international sites, such as from Ascension Island, the Middle East and even Singapore, can be “covered” from Woofferton, minimizing the impact on listeners if a breakdown occurs.

MAINTENANCE

A shortwave transmitter station is a complex mix of engineering disciplines — from high-voltage electricity and radio frequency and traditional audio engineering, through to modern computer processors, which run the station’s automation and control systems.

Throughout a typical day, the duty engineers coordinate any changes to the transmission schedule, which may be required to allow maintenance and repairs to be carried out.

Non-radiating towers support the latticework of HF curtain antennas.

Ensuring the safety of staff working inside the transmitter enclosures and outside on the antennas is essential: a safety lock out system is used to isolate the equipment to be worked on, with unique physical “keys” and interlocks needed to make sure systems cannot be used or become live until the engineers and riggers are safely clear of high voltages and radiating elements.

Surprisingly maybe, the middle part of the day is one of the “quietest” periods at the site, as most transmissions take place during the early morning and evening, due to the time differences between the U.K. and audiences in Africa and the Middle East. This is therefore the ideal time to carry out routine maintenance to the transmitters, some of which are still going strong after 40 years of service thanks to the skills and expertise of the Woofferton engineers.

One of the station’s four RIZ 250 kW transmitters that is used daily for the BBC’s DRM transmission to Europe.

They need a carefully planned regime of regular checks and preventative work to keep them on the air, as well as some tender loving care — something which is in no short supply at Woofferton. A myriad of maintenance tasks are carried out, which include checking the RF, modulator and water cooling systems, and testing individual components such as resistors and capacitors, and of course the valves themselves.

Any faulty components will be replaced with spares from stores, or as is sometimes required when items are obsolete, manufactured on-site by the station’s workshop. The mechanical and electrical engineers can fabricate bespoke metalwork and fittings which are no longer available, as well as carry out maintenance to the stations “heavy” equipment such as HV transformers, fan units, gas compressors and pumps.

MISSION-CRITICAL ROLE

At around 3 p.m. GMT each day, the station comes alive as the evening transmissions for Africa and Middle East start to ramp up and by 6 p.m. almost every transmitter is on-air, broadcasting in languages such as Arabic, French, Hausa, Amharic, Kurdish, Dari, Pashto and Russian, as well as English.

DT700 monitoring receivers analyze the parameters of DRM broadcasts from the station’s digital transmitters.

In recent years, Woofferton has also taken on a new role in being one of a few sites around the world where satellite carrier monitoring is carried out, to check and report on the performance of quality of satellite distribution of the BBC’s international TV and radio channels.

More than 75 years after its first broadcast to wartime occupied Europe, Woofferton continues to demonstrate the unique and enduring power of shortwave broadcasting — especially in parts of the world where media freedom and access to objective news is sometimes made deliberately difficult for international broadcasters to reach. And it’s still proud of its critical role in informing, entertaining and educating millions of listeners around the world.

On Sept. 22 in Bengaluru, ahead of the cricket match with South Africa, All India Radio hosted a public roadshow event designed to highlight DRM sets in cars that are receiving digital services from AIR.

The event followed the recent announcement made by Shashi Vempathi, the public radio and television Prasar Bharati’s CEO, who revealed that live cricket commentary would return to AIR and be broadcast on DRM for the first time.

According to the Digital Radio Mondiale consortium, the cricket matches, the most popular sport in India, serve as an ideal space for publicizing DRM’s features, including data reception. In addition to receiving sports updates participants in Bengaluru can also receive agricultural produce market rates.

This document amends the FM Table of Allotments, of the Commission's rules, by reinstating certain vacant FM allotments. These FM allotments are considered vacant because of the cancellation of the associated authorizations and licenses, or the dismissal of long-form auction applications. Theses vacant FM allotments have previously undergone notice and comment rule making. Reinstatement of the vacant allotments is merely a ministerial action to effectuate licensing procedures. Therefore, we find for good cause that further notice and comment are unnecessary.
