Imagine tuning in to your favorite radio shows only to be greeted by crackling static and fuzzy reception—frustrating, right? That's been the reality for Perth residents listening to ABC Radio on the AM band for over a century. But get ready for a game-changer: in 2026, these stations are making the leap to FM, promising crystal-clear sound and a smoother listening experience. But here's where it gets controversial—is this shift a savvy upgrade or a shortsighted farewell to a broadcasting tradition that still has its loyal fans? Let's dive in and unpack the details.
Nearly 102 years after ABC Radio burst onto the scene in Australia, Perth's audience is on the cusp of a significant audio enhancement. The network's trio of AM stations—ABC Radio Perth, Radio National, and News Radio—are set to transition to FM frequencies starting in 2026. This eagerly anticipated change stems from a decision by the Australian Communications and Media Authority (ACMA) to adjust the radio licensing plans for Perth and the remote Western Australia areas, paving the way for this fresh start.
ABC's managing director, Hugh Marks, described it as a thrilling chance to elevate the service quality for Perth's listeners. "We've been grappling with the hurdles of AM reception in this city for ages," he shared. "Switching to FM means our audiences will relish superior audio fidelity and more dependable transmissions, keeping them hooked on the content they cherish." Expanding on this, think of it like upgrading from an old vinyl record player to a high-definition streaming device—suddenly, every nuance in the music or dialogue pops with clarity.
Building on that, ABC's director of audio, Ben Latimer, emphasized that the FM migration isn't just about better sound; it also brings substantial financial perks. "These fresh FM licenses will offer top-notch audio quality at a fraction of the cost, delivering greater taxpayer value as AM's popularity wanes in major cities," Latimer explained. "This move underscores our dedication to refining radio offerings and ensuring top-tier broadcasts nationwide." To put this in perspective for beginners, imagine AM as an old-school bicycle that's reliable but limited, while FM is like a sleek electric scooter—faster, more efficient, and easier to maintain.
The exact switchover timeline and the new frequencies for the stations will be revealed early next year. But why has AM been such a headache in Perth? The root cause ties into how AM signals are sent out and a quirky local fact: Perth's sandy, arid soil.
While we talk about radio waves in the "air," AM actually depends heavily on ground waves for transmission. "AM broadcasts originate from specific locations chosen for optimal signal spread," clarified Gavin Bowman, ABC's manager of transmission contracts. "These waves travel effectively along the earth, so we select spots with excellent ground conductivity." He added that AM thrives on moist, damp soil to extend reach, which is why transmitters are often placed in swamps or near rivers. Perth, however, rests on the Swan coastal plain, famous for its parched, sandy terrain that can go rainless for months. This dry environment hampers ground wave propagation, leading to weaker signals. For those new to this, picture AM as a swimmer who needs a pool of water to move swiftly, but Perth offers only a dry sandbox—inefficient at best.
And this is the part most people miss: the sheer space AM demands in urban settings. Since 1939, the ABC Radio Perth AM transmitter has occupied a vast bushland reserve in Hamersley's northern suburbs, complete with a restricted area around its towering 180-meter mast. FM broadcasts, by contrast, rely on hilltop masts using line-of-sight propagation, needing far less real estate.
"The visible mast is just a fraction of the AM setup," Bowman elaborated. "A key component involves burying extra wires into the ground to effectively lengthen the antenna electrically. These radial wires radiate the signal along the earth more powerfully than a mast alone. Consequently, we require enormous tracts of land—think multiple acres." Not only does this consume significant space in bustling cities, but each AM mast supports only one or two channels, meaning every station needs its own "paddock." FM and TV, on the other hand, can share infrastructure on a single hilltop site, spreading costs across numerous services. "This shared setup allows for efficient resource use that AM simply can't match," he noted. As a beginner-friendly example, compare AM to building separate garages for each car, while FM lets multiple vehicles park in one shared lot—much more economical.
But here's where it gets controversial: critics might argue this shift prioritizes cost savings over preserving AM's unique, broad-reaching capabilities for emergency or rural listeners. Is abandoning AM in cities a smart evolution, or does it risk marginalizing older technologies that still serve niche needs? As if Perth's sandy soil and land use weren't challenges enough, the 1990s expansion of the railway network—running north and south through the Mitchell and Kwinana freeways—added insult to injury. The electrified tracks generate interference, making AM radio reception in cars on these highways virtually unbearable.
"When a train passes by while you're tuned to AM, it severely degrades your listening experience," Bowman pointed out. For countless daily commuters, this has meant habitually switching off AM stations during freeway drives, opting instead for clearer alternatives.
This transition marks the close of a chapter for ABC Radio Perth, originally launched as 6WF (later 720), which began airing just over 101 years ago on June 4, 1924. Interestingly, it wasn't an ABC initiative at first. Instead, it was a commercial venture by the Westralian Farmers Co-operative (now Wesfarmers), aimed at combating loneliness for rural folks. Wesfarmers' archives recount how John Thomson, a wheat department leader, conceived the idea after a stranded car incident on a remote wheatbelt road near Bruce Rock. Stuck with two flat tires and waiting hours for help, he pondered the profound solitude of countryside life and saw emerging radio technology as the answer. Despite diverging from Wesfarmers' core business, Thomson convinced superiors to pursue Perth's first radio license. The station adopted the 6WF call sign, reflecting Wesfarmers' initials. Four years later, tired of the radio enterprise, Wesfarmers offloaded 6WF to the Commonwealth government, which integrated it into the ABC's local network.
Latimer reassured that the Perth FM shift won't disrupt regional radio or emergency broadcasting. "We're lucky to have robust AM transmitters in surrounding regions, ensuring emergency alerts reach everyone outside Perth's metro area previously served by the local AM signal," he stated.
So, what do you think? Is the ABC's move to FM a progressive step forward, or should we hold onto AM for its historical significance and potential future utility? Does this change excite you as a listener, or do you worry about losing access in certain scenarios?
