The Shepparton transmitter site of ABC/Radio Australia

Developments in the Australian domestic HF broadcasting scene

by Nigel Holmes

Radio broadcast on HF (high frequency or shortwave) has a solid role to play in the pantheon of media in the Australian and pan-Pacific context. It might be off the radar for the urban masses, but HF radio is the proven, economical alternative to satellite and cable for communication over continental or oceanic distances. Our commercial airlines use HF radio every day. So do our mining companies and emergency services. People holidaying in our remote areas buy or rent HF transceivers for their cars. Australia has the largest number of civilian users of HF radio in the world.

For thirty years a simple system of three HF transmitters quietly provided Australian Broadcasting Corporation (ABC) radio to remote populations across inland Australia, the Northern Territory (NT). Centered on Alice Springs, Tennant Creek and Katherine each transmitter reached out nominally 450 km, covering an area of nearly 2 million square kilometres. In practice the area serviced was larger, extending into Queensland and Western Australia. Such is the utility of this versatile medium. The audience was small, only a couple of hundred thousand, living or moving through the most remote places in Australia, but this was their lifeline.

During the cyclone season, storm alerts and flood warnings would reach people in the inland beyond the call of AM and FM networks. Yes, such people do exist in Australia and elsewhere in the Pacific.

Like many marginalised communities the HF radio listeners of the outback struggled to make urban elites understand their very real world. So in 2016 when the ABC announced the closure of the domestic HF transmitters in order to fund its DAB+ radio rollout in Canberra and Hobart, the backlash from the remote communities was shrugged off and the closures proceeded in 2017. ABC pointed at its satellite as an alternative, but had no answer when asked how to equip a jillaroo’s horse, a dusty 4WD or an offshore tinnie with a fragile satellite dish, an expensive receiver and the power point to run it all.

People who are used to an effective service tend to take its loss badly. So it has been in the NT. Politicians were pursued by the inland listeners wanting a better deal. The matter has culminated with the main opposition Australian Labor Party pledging to restore the HF distribution of ABC within Australia if it wins the forthcoming the federal election.

Let’s hope political expediency at the federal government level and within ABC doesn’t foul this up. We don’t want a half-baked resurrection as a sop to fend off critics of the ABC or to let politicians grandstand.

The three domestic HF sites in the NT cost a lot more than AUD$1.9 million p.a. to run. That was a figure bandied about by ABC after criticism of its DAB+ expansion costs. But for a sum in the order of half that, plus re-establishment costs, a service can be implemented which would have greater coverage, better reliability and lower outgoings. What’s not to like? The key is the former Radio Australia HF station at Shepparton, Victoria.

The cost of electricity at the NT sites was horrendous. Apart from feeding three thirsty 50 kW tx, huge air conditioning plant was required at each site to pull out waste heat and combat 50°C summer temperatures. Maintenance costs were savage. On-air availability was lousy (worst in the ABC network) because of environmental challenges and long maintenance travel times.

So here’s a plan: re-locate a near-new Continental 418G HF 100 kW transmitter from Tennant Creek to Shepparton. Electricity is much cheaper and more reliable at Shepparton. It’s a cooler site and has permanent, trained staff. The consolidation of spares and expertise with the other Continental transmitters at Shepparton makes engineering and economic sense. Re-locate the two small 6-12 MHz HR2/2/0.4 and HR2/2/0.6 aerials from the former RA station at Brandon. Erect them both as AHR2/2/0.4, align one on a boresight of 000°T and the other one on a boresight of 320°T. Feed both aerials from the transmitter via a splitter, run the transmitter at 80 kW so each array receives 40 kW. Run a 5.9 MHz channel at night and a 9 or 11 MHz channel during daylight. Bingo. You now have a two-frequency network covering the sector between 020° & 300° at a range of 1500 km -> 3000+ km. What a great conduit for cyclone/flood alerts, quality news and entertainment and if the ABC can manage that then it might just get back to meeting its charter obligations to all Australians.

On Thanksgiving, WPAQ will replay a 1948 Mount Airy H.S. Football Game

1 Reply

Many thanks to SWLing Post contributor, Kim Elliott, who shares this fascinating story from WBUR:

For the past 70 years, WPAQ out of Mount Airy, North Carolina — population 10,000 — has broadcast bluegrass and old-time string music.

But music isn’t all you’ll hear on WPAQ.

“If folks call in and say they’ve lost an animal or they’ve found an animal, we will be happy to announce that,” says Brack Llewellyn, a part-time announcer who’s worked on and off at the station since the ’80s.

[…]Kelly Epperson took over WPAQ from his father, Ralph Epperson, who died in 2006. A few weeks ago Kelly was digging around his father’s old office.

“My dad, he held onto everything — it drove my mom crazy,” Kelly says. “And actually in the corner, I saw a box that was sort of halfway open. And I kinda kicked at it a little bit — just to make sure there were no snakes around, ‘cause we have a lot of black snakes up here. But anyway — it was heavy. And I opened up the lid. There were some records in there. And I looked at the label and I couldn’t believe it. It said: ‘Mount Airy vs. Laurinburg. Football. Nov. 25, 1948.’ ”

It was the state championship game, held on Thanksgiving Day.

Kelly didn’t have the equipment at WPAQ to play the records — they’re old lacquer discs — but he took them to a woman who did.

[…]The 2018 Mount Airy Bears had a bye week coming up. There was a Friday night open on WPAQ’s calendar.

So on Sept. 28 at 7:30, when residents of Mount Airy, North Carolina, turned to 740 on their AM dials, they heard this.

“N.W. Quick — co-captain and right tackle of the Laurinburg Scots from Scotland County — the Fighting Scots they’re called — will be kicking off for Laurinburg on the 40-yard line.”

Kelly and Brack say they started hearing from listeners right away.

“We went about as viral as you can in this area with our broadcast,” Brack laughs.

“And I’m trying to concentrate — I was running the board — and I was getting all these messages,” Kelly says. “They were blowing up my phone. I couldn’t handle it. Saying, ‘This is unbelievable! I’m hearing my dad play. I never thought I could ever do this. My dad is playing a football game.’ “

Brack says he heard from one friend who grew up in Laurinburg and recognized the name of a player on the Scots roster.

“And the player whose name he heard grew up to be the doctor who delivered him,” Brack says.

[…]I’d tell you how the game ends, but I don’t want to spoil it — because you’re going to get another chance to listen. WPAQ is rebroadcasting the game one more time, this Thanksgiving Day at 2 p.m. ET.

“So who wants to watch the Detroit Lions when they can hear the 1948 North Carolina 1A State championship game?” Kelly laughs.

Many thanks to SWLing Post contributor, John Figliozzi, who writes:

I figure you’re the best source to get word of this out. Heartland America (1-800-229-2901) (www.heartlandamerica.com) is selling refurbished Grundig Executive Satellit receivers for $129.99 (MSRP $229.99).

The ad states “Factory serviced to meet original quality standards – may have slight cosmetic blemishes”.

It is Item No. 1Z-94828.

I have one of these I bought earlier this year on a similar deal from Heartland America. It works and plays perfectly and if there is a blemish, I’ve yet to find it. This is an excellent portable at a bargain price.

Excellent, John! Thanks for the tip!

SpaceX’s Falcon 9 payload includes the HawkEye 360 radio-wave emission seeker

Many thanks to SWLing Post contributor, Balázs Kovács, who shares the following:

Hi Thomas,

Just found: the launch of the SpaceX’s Falcon 9 rocket was delayed today, part of the load is a new radio-wave emission seeker satellite system the Pathfinder from HawkEye 360:
https://www.businessinsider.com/spacex-to-launch-70-satellites-radio-tracking-2018-11

Some parts from the article:

“An unprecedented rocket mission for SpaceX, called SSO-A, will launch 71 small satellites at once on Monday. Three of the satellites belong to HawkEye 360, a startup that aims to “see” radio-wave emissions all over Earth. HawkEye 360’s software will identify each unique radio signal and use it to track “dark ships” that may be trying to hide illegal activities.”

[..] The antennas of Pathfinder can detect a wide range of radio signals above about 1 watt in power. [..] This means the cluster can triangulate normally hard-to-pinpoint signals from satellite phones, push-to-talk radios, and marine radar. [..] In the future, they aim to launch five more three-satellite clusters, which will create a constellation that can map Earth’s radio signals once every 30 to 40 minutes. [..] Another planned use of Pathfinder is more down-to-earth: The technology could detect improper use of the radio-frequency spectrum, including interference between cell-phone towers.”

Thank you for the tip, Balázs!

I also discovered the following short video which introduces and describes the system:

Sounds like an amazing system although it certainly does feel a little “big brother”–!

If elected, Labor commits to provide $2 million to restore ABC shortwave radio

Many thanks to SWLing Post contributor, Ian P, who shares the following story and interview via ABC News Northern Territory Country Hour. I strongly suggest listening to the full seven plus minute interview via the embedded audio player below:

If elected next year, Federal Labor says it will provide the ABC with $2 million in funding to help re-establish shortwave radio services across the Northern Territory.

The ABC controversially switched off its shortwave service in January 2017, and defended the decision by saying it would “only affect a very, very small amount of people” and save taxpayers up to $1.9 million.

The decision was heavily criticised by industry groups such as the NT Cattlemen’s Association (NTCA) and the NT Seafood Council.

NTCA president Chris Nott welcomed today’s announcement by Labor and said the ABC’s decision was short-sighted.

“What people take for granted in the cities is a luxury for those of us in the bush,” Mr Nott said.

“We rely on the HF shortwave radio transmitters because we don’t have mobile and data coverage for AM and FM radio stations.

“The ABC can expand its modern day platforms all it likes but the truth is we don’t all have access to it and the ABC did not care at all about the impact of its decision.”

Federal Member for Solomon Luke Gosling, said the axing of shortwave had angered a lot of people and community groups.

“Many thousands will benefit from this [bringing back shortwave],” he told the Country Hour.

“I was lobbied by a really large cross-section of the community that spends time in remote areas and when shortwave was cut there was a lot of angst, so it will be a good thing to bring it back to keep people on the land and waters connected.”
