Radio Waves: ABC Wage Freeze, A Titanic Radio, FCC “Tweaks” LPFM Rules, and Digitizing a DX-160 Display

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Michael Bird, Dave Zantow, David Korchin, and Alokesh Gupta for the following tips:


ABC must freeze wages, government warns (The Guardian)

The Morrison government has put the national broadcaster on notice that it expects the ABC to embark on a six-month wage freeze to bring it in line with other taxpayer-funded agencies during the Covid-19 crisis.

The warning follows the government’s decision in early April to defer general wage increases for commonwealth public servants for six months. The public service commissioner followed up that directive by writing to all non-public service agencies – including the ABC – informing them the government expected them to adopt the same practice.

With no clear response from the ABC to the 9 April missive, Guardian Australia understands the communications minister Paul Fletcher wrote to the national broadcaster this week flagging his expectation that the organisation would defer a 2% increase for all employees scheduled to take effect in October under the ABC’s enterprise agreement.[…]

Radio used by the Titanic to call for help can be salvaged, judge rules (CNN)

A federal judge has ruled that RMS Titanic Inc. can salvage the radio used to call for help by the fated ocean liner after it struck an iceberg in 1912.

To get to the radio, divers would need to remove a part of the ship’s deckhand to reach the room known as the Marconi Suite, which houses the device.

The ruling modified an order issued on July 28, 2000, that said that RMS Titanic Inc. could not cut into the wreckage or detach any part of it.

Virginia’s eastern district court amended that order “for a unique opportunity to recover an artifact that will contribute to the legacy left by the indelible loss of the Titanic, those who survived and those who gave their lives in the sinking,” Judge Rebecca Beach Smith wrote.

Experts in the case testified to the “significant deterioration” in areas above and around the Marconi room, according to the document, and photos showed the “increasing breakdown” in the deck above the suite.

The suite, made of steel, consisted of three areas: sleeping accommodations, an operator’s room and the silent room that housed the radio. Each area was separated by wood walls that officials believe have dissolved, according to court documents.

The Marconi device and the artifacts associated with it face “significant threat of permanent loss,” the judge said in her approval of the expedition.[]

FCC Tweaks LPFM Technical Rules (Radio World)

The FCC in April modified the technical rules covering low-power FM stations. It expanded the permissible use of directional antennas; permitted waivers of protections of television Channel 6 by a specific group of reserved channel stations; expanded the definition of minor change applications for LPFM stations; and allowed LPFM stations to own boosters. Read more about the changes here.

Michelle Bradley, founder of REC Networks, is an engineer and longtime LPFM advocate.

Radio World: What’s your overall assessment of the outcome and the scope of its impact in the LPFM community?

Michelle Bradley: While the FCC did not address three major issues that are impacting LPFM stations right now —the ability to address building penetration issues, the ability to reach “local” listeners in rural areas and the disparity in how LPFM stations protect FM translators vs. how translators protect LPFMs — the changes will benefit current LPFM stations by giving them more flexibility in moving locations, reduce the need for waivers and improve LPFM service in the southern border region. It will also open some additional opportunities for new LPFM stations in the next filing window.[]

RadioShack Shortwave Goes Digital (Hackaday)

If you spent the 1970s obsessively browsing through the Radio Shack catalog, you probably remember the DX-160 shortwave receiver. You might have even had one. The radio looked suspiciously like the less expensive Eico of the same era, but it had that amazing-looking bandspread dial, instead of the Eico’s uncalibrated single turn knob number 1 to 10. Finding an exact frequency was an artful process of using both knobs, but [Frank] decided to refit his with a digital frequency display.

Even if you don’t have a DX-160, the techniques [Frank]  uses are pretty applicable to old receivers like this. In this case, the radio is a single conversion superhet with a variable frequency oscillator (VFO), so you need only read that frequency and then add or subtract the IF before display. If you can find a place to tap the VFO without perturbing it too much, you should be able to pull the same stunt.

In this receiver’s heyday, this would have been a formidable project. Today, a cheap digital display will do fine.[]

Guest Post: Report from the 2019 Henry’s Island DXpediton

Many thanks to SWLing Post contributor, Sandipan Basu Mallick (VU3JXD), for sharing the following guest post:


Henry’s Island DXpediton 2019

World Radio day is observed by the UNESCO on 13th February every year. This year is the 8th year world day being celebrated with theme “celebrate radio and how it shapes our lives”.  In recent times there has been a sea change in radio listening and radio broadcasting. More and more radio broadcasters are shifting to FM which radiate over a small distances and require low power transmitters. Medium wave broadcasting and shortwave broadcasting which is used to reach audience over larger distances is gradually becoming less important with the growth of internet connectivity. Broadcasters are increasingly streaming their content over the internet to reach their audience via the PC, Laptop and now via the mobile phone.

DXing is the hobby of listening to the faraway and distant signals and the hobbyist are called DXers. DXers would switch on their radio set, connect it to the piece of wire which is the antenna and turn the dial to search and listen to the far away and sometimes feeble radio signals. For these radio enthusiasts challenge is becoming greater. The big names of yesteryear such as BBC, Voice of America, Radio Moscow and Deutsche Welle, the German radio are all gradually shifting their content from shortwave broadcasting to the internet. Now with data connectivity to the mobile phone available to everyone, the shortwave broadcasters find a more reliable and popular route to reach their audience through the internet rather than troublesome “bounce” through the ionosphere. Then with the rise of household electrical devices which radiate “radio noise” such as the LED bulb or the TV, the radio signals from distant lands have to rise over this local noise to reach the ear of the audience.

That is why a band of radio enthusiasts from all over India have travelled to the listening camp set up at a resort in Henry Island at Bakkhali in the state of West Bengal, India. This year the listening camp ran from 10th – 13th Feb, which celebrated World Radio Day and the hobby of radio. The dedicated radio enthusiasts who have been drawn into this radio listening camp, are drawn from different parts of country varying from New Delhi to Tripura. Kolkata the home of the Indian DX club International (www.idxci.in), has been promoting the hobby since 1980 has naturally most participants in this camp. They were very upbeat while worldwide radio enthusiasts have to cope up with bad news for the hobby. In the last few years, stations after stations have closed down and so have iconic radio clubs like Danish Short Wave Club and periodicals like Monitoring Times. Broadcasting mega corporations like VOA and DW have reduced their presence in the airwaves to a faint whisper compared to their former roar.

Sandipan Basu Mallick (VU3JXD) with Dr Supratik Sanatani (VU2IFB)

Sandipan Baus Mallick (VU3JXD), who is the principal in organizing this year’s DXpedition from IDXCI says that the appeal of radio is still there among the various age groups. These camps are set up in remote locations, which enable the radio enthusiast to come together with likeminded people to exchange ideas and experiment with their equipments and brush up their skills with conventional radio. People from various races of life participated in this years camp.

Among the participants Sudipto Ghose (VU2UT) who just retired from a job with the Ministry of Finance is drawn by the technical part of the hobby and toys with new radio receivers and accessories such as antennas and preamplifiers.

C K Raman (VU3DJQ) from Delhi whose job incidentally involved professionally monitoring broadcast stations, has narrowed his interest down to the medium wave stations and the tropical band stations such as stations from Brazil, Colombia and Indonesia and has come down looking for such exotic signals.

Suvendu Das (SWL), who professionally managed ship communications has suddenly become interested in the hobby of broadcast band listening.

Pradip Kundu (SWL) of Tripura who after retiring as a Principal has more time to pursue his childhood passion and is an avid QSL collector.

Babul Gupta (VU3ZBG) an interior designer still spends time to seek those rare signals at the wee hours and has to his credit listening to some of the most rare to hear stations from India such as Cross Radio, an evangelist radio station broadcasting from the Carribean.

Alokesh Gupta (VU3BSE) has flown in from Delhi for the radio camp is an avid enthusiast who also served to coordinate the Listeners association of Radio Taiwan and runs the website radioactivity.org which disseminates information related to radio broadcasting.

Kallol Nath (SWL) is among the newest entrants in the DXer squad. Armed with XH Data D-808 receiver, he logged a number of pirate stations on the MW band.

For Sandipan, a marketing professional worked to set up this camp and bring together radio enthusiast from various parts of India. He is also drawn by the technical aspects of the hobby and can flaunt many a radio gear just like his friend Debanjan Chakraborty (VU3DCH) who is a radio collector and has radio sets.

Accompanying them is Eye Surgeon Dr Supratik Sanatani (VU2IFB), who has key interest in home brewing various radio equipment, and a veteran in DXpedition also came together explore the airwaves from the Bay of Bengal.

Henry’s Island marked with a red location pin.

Henry’s Island is at the tip of the Bay of Bengal which for the radio listener gives a good opportunity to hear distant signals from Australia, New Zealand, Oceania, Indonesian archipelago and Papua New Guiniea.

DXpeditioners strung long wire antennas aimed in their favorite direction and then connect their modern digital radio receivers to try to catch the feeble signals from exotic radio stations. During their whole night listening sessions, some would exclaim at 2.30 am that the Phillipines medium wave station was opening with a greeting its local audience in the local language Tagalog–or someone might simply record the Maldivian medium wave station from Male ending its transmission with their national anthem. The fisheries ground also has the advantage of low noise from electrical devices. To run away from local noise, the hobbyist might even have to pitch a tent in the middle of nowhere and use their advanced radio receivers with battery power.

What is the pinnacle of success? Just like the bird watcher catching a glimpse of the rare migratory bird, for the DXers it is the thrill of listening to exotic signals such as from the American Forces Military Base at Diego Garcia to the barely audible Papua New Guinean station from Port Moresby. Then there are others like that Peruvian station Radio Tarma with excited football commentary which comes through to India only during a short window in the very early morning before day break and only on few days in a year. Even though the 11 year old solar sunspot cycle which influences radio transmission, is at its favorable “ low”, we can still confirm that DXing as a hobby is still alive and kicking!!!

DXers in Action


Thank you so much for sharing this report, Sandipan! It appears that you not only enjoyed some excellent DX on Henry’s Island, but you also strengthened friendships that will last a lifetime. Well done!
