Finding the Kookaburra on Shortwave—Past and Present

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

Hi Thomas

I still have warm memories of tuning into Radio Australia on 9580 kHz at sunrise during my early days of shortwave listening. They would sign on with their Waltzing Matilda interval signal and the sound of the kookaburra bird.

While doing some listening on the SDR of my friend Ken (VE3HLS) who has retired to northern Thailand, I have discovered you can still hear the kookaburra on shortwave by tuning into Reach Beyond Australia. Their broadcast to Myanmar in Burmese from 1500 to 1530 UTC on 11900 kHz can be very well heard on this Kiwi. There is a brief English announcement at sign and sign off, as well as a few seconds of “kookaburra chatter.”

Attached are two recordings, the first at sign on (March 7, 2025) and the second at sign off (December 1, 2024).

Radio World: NRSC Studies RF Noise on Various Roadway Types

Many thanks to SWLing Post contributor, Dennis Dure, who shares the following item from Radio World:

NRSC Studies RF Noise on Various Roadway Types (Radio World)

Radio World asked Cris Alexander to read the report and comment

The National Radio Systems Committee recently published the results of a study on AM band noise.

The report, principally authored by John Kean, is titled NRSC-R102, “Measurement of AM Band RF Noise Levels and Station Signal Attenuation.” It was released in January.

The study consisted of several measurement series conducted along roadways both in urban and rural areas, measuring the signal strength of three different Baltimore/Washington 50 kW AM stations as well as the RF noise on three different unoccupied AM band frequencies.

Measurements were made across five environments: rural, rural-suburban, suburban, urban and dense urban. The results were mostly as one would expect, but there were a few surprises. [Continue reading…]

Blackout in Chile: A Reminder of Radio’s Role When All Else Fails

Many thanks to SWling Post contributor Carlos Latuff, who writes:

Good morning, Thomas. I just translated this article from Chilean radio station “Canal 95”, published on February 26. Original in Spanish here: https://www.canal95.cl/magazine/apagon-redes-sociales-rinden-tributo-radio-pila


After the blackout, social media pays tribute to battery-operated radios

Social media users highlighted the importance of battery-operated radios as the only reliable source of information in emergencies, while critics pointed to the fragility of the current system.

After a large blackout left much of Chile without electricity last Tuesday, millions of people were affected and left without communication. All due the fact that the telecommunications and internet antennas service completely collapsed.

In this scenario, and in the absence of real-time information, social media users began to highlight the importance of having battery-powered radios to access news in emergencies such as, for example, the decision to declare a curfew.

“Will we have to go back to copper wire telephones? Cell phones ‘died’ in the emergency. Explanations are useless in the face of a serious incident. Earthquake, tsunami, flood, or power outage like yesterday. Totally incommunicado. Only the battery-operated radio worked ,” remarked the renowned journalist and radio personality, Sergio Campos.

Many also recalled that this device has been key during earthquakes and other disasters in the country, although there was no shortage of jokes.

“Serious question: does everyone really have a battery-operated radio?” asked one user of the X platform. “It’s always good to have one. My mother-in-law has one and it’s super old, but it works. And the radio too,” joked comedian Luis Slimming.

Although some users admitted not having a functional radio at home, implying that they had not previously considered it necessary due to the outdated technology, other users reinforced the importance of having one of these reliable devices that allow them to stay in touch.

The work of radio stations that continued to operate during the emergency was also highlighted. There was no shortage of criticism of telephone companies and the widespread use of smartphones that do not have integrated FM radio.

“I want to give a round of applause to Chilean radio stations. We would still be going around in circles if it weren’t for the fact that they continued to broadcast and report on what was happening. Every Chilean home should have a battery-operated radio ,” wrote @satoruswft .

It remains to be noted that Chile has historically faced natural events that disrupt basic services, but the current dependence on the Internet and cell phones has created a gap in preparation for blackouts.

So, keep this in mind: a battery-powered radio is still a must-have in an emergency.
