Podcast #294 – Reading the PIRATE Act / FCC & the Supremes Pt. 2

The PIRATE Act was signed into law more than a year ago, but the rules governing increased fines for unlicensed broadcasting are about to go into effect on April 26. The Act is intended to give the FCC additional tools for tamping down pirate radio activity in hot beds like Boston and Brooklyn, NY, but there are reasons to be skeptical.

Brooklyn-based writer, post-production mixer and field recordist David Goren joins to help us tease out the real-world implications. Goren is also the creator of the Brooklyn Pirate Radio Sound Map and has been monitoring and recording unlicensed radio activity in the borough for decades.

Also joining the show is Dr. Christopher Terry from the University of Minnesota. A professor of media law, he helps illuminate some of the legal and bureaucratic elements that complicate the Commission’s efforts. He also catches us up on the latest development in the battle over media ownership rules, with the Supreme Court issuing a narrow unanimous ruling in favor of the FCC’s most recent changes, but not quite addressing the decades-long gridlock in that policy area.

WSPR May Hold The Key To MH370 Final Position (Hackaday)

The disappearance of Malaysia Airlines flight MH370 after an unexplained course change sent it flying south over the Indian Ocean in March 2014 still holds the mystery of the wreck’s final location. There have been a variety of efforts to narrow down a possible search area over the years, and now we have news of a further angle from an unexpected source. It’s possible that the aircraft’s path could show up in radio scatter detectable as anomalously long-distance contacts using the amateur radio WSPR protocol.

WSPR is a low-power amateur radio mode designed to probe and record the radio propagation capabilities of the atmosphere. Transmit beacons and receiving stations run continuously, and all contacts however fleeting are recorded to an online database. This can be mined by researchers with an interest in the atmosphere, but in this case it might also provide clues to the missing airliner’s flightpath. By searching for anomalously long-distance WSPR contacts whose path crosses the expected position of MH370 it’s possible to spot moments when the aircraft formed a reflector for the radio waves.[…]

Bob Fass, Pioneer of Underground Radio, Dies at 87 (NY Times)

His provocative “Radio Unnameable,” long a staple of the New York station WBAI, offered a home on the FM dial to everyone from Abbie Hoffman to Tiny Tim.

Bob Fass, who for more than 50 years hosted an anarchic and influential radio show on New York’s countercultural FM station WBAI that mixed political conversation, avant-garde music, serendipitous encounters and outright agitation, died on Saturday in Monroe, N.C., where he lived in recent years. He was 87.

His wife, Lynnie Tofte, said he had been hospitalized with Covid 19 earlier in the month, but he died of congestive heart failure.

Vatican Radio celebrates 30th International Marconi Day

The Dicastery for Communication marks the 30th International Marconi Day with a celebration at Vatican Radio’s historic broadcast station outside Rome.

International Marconi Day is held every year on the Saturday closest to the birthday of the inventor of the radio, Guglielmo Marconi, on 25 April 1874.

This year’s commemoration fell a day earlier, and saw dozens of radio stations exchange messages, including Vatican Radio, which Marconi himself helped found in 1931.

The 30th iteration of Marconi Day was celebrated at Vatican Radio’s broadcast center at Santa Maria di Galeria, outside Rome.

Day for those who love radio

According to Dr. Paolo Ruffini, the Prefect of the Dicastery for Communication, it was “a day spent in a family spirit” for those who love the Radio and the man who invented it.

He noted that the broadcast station forms both the center and periphery of Vatican Radio, since it is the place where radio waves are emitted which carry the Gospel and the words of the Popes throughout the world.

Marconi’s favorite Radio

The 30th Marconi Day falls within the 90th anniversary year of the founding of Vatican Radio.

The great Italian inventor’s daughter, Princess Elettra Marconi, who was present for the celebration, recalled that the station was her father’s favorite, though he had founded several others.[]

FCC Fines HobbyKing Nearly $3 Million for Marketing Unauthorized Drone Transmitters (ARRL News)

The FCC has issued a Forfeiture Order (FO) calling for HobbyKing to pay a fine of $2,861,128 for marketing drone transmitters that do not comply with FCC rules. An FCC Enforcement Bureau investigation stemmed in part from a 2017 ARRL complaint that HobbyKing was selling drone transmitters that operated on amateur and non-amateur frequencies, in some instances marketing them as amateur radio equipment. The fine affirms the monetary penalty sought in a June 2018 FCC Notice of Apparent Liability (NAL). The FCC said its investigation found that dozens of devices marketed by the company transmitted in unauthorized radio frequency bands and, in some cases, operated at excessive power levels. “Such unlawful transmissions could interfere with key government and public safety services, like aviation systems,” the FCC said.“We have fully considered HobbyKing’s response to the NAL, which does not contest any facts and includes only a variety of legal arguments, none of which we find persuasive,” the FCC said in the FO. “We therefore adopt the $2,861,128 forfeiture penalty proposed in the NAL.”[]

High School Marine Buoy Transmitter Now Active on 20-Meter WSPR (ARRL News)

Phil Karn, KA9Q; Randy Standke, KQ6RS, and members of the Mount Carmel High School Amateur Radio Club (MCHSARC) in San Diego have constructed and deployed an amateur radio marine buoy in the Pacific. The buoy, which transmits WSPR on 14.0956 MHz USB, has already been heard around the continental US, Brazil, Hawaii, Japan, Costa Rica, Australia, and South Africa.

“Over the past year, Randy and I have mentored the MCHSARC in designing and constructing a simple marine buoy that was deployed from the RV Sally Ride [on July 16], about 700 kilometers off the coast of southern California,” Karn said in a post on the AMSAT Bulletin Board. “It is up and transmitting WSPR on 20 meters using the call sign KQ6RS, and is being received all over the US and into Canada and Brazil.” Karn is blogging about the project with updates.

The electronics are the 20-meter WSPR version of the WB8ELK “pico tracker” that has been flown on long-duration balloons. “We removed the solar panels and substituted 21 ordinary alkaline D cells, wired to supply 4.5 V,” Karn explained. “We estimate battery lifetime will be 6 months.”

[…]The first reception report was on July 16 at 12:52:30 UTC from grid square CL89eu, although the current carried the buoy east into CL89fu at 20:32:30 UTC. The buoy (KQ6RS-1) can be tracked on the APRS and WSPRnet sites.[]

Stop Bad Laws Before They Start (Hackaday)

With everything else going on this summer, you might be forgiven for not keeping abreast of new proposed regulatory frameworks, but if you’re interested in software-defined radio (SDR) or even reflashing your WiFi router, you should. Right now, there’s a proposal to essentially prevent you from flashing your own firmware/software to any product with a radio in it before the European Commission. This obviously matters to Europeans, but because manufacturers often build hardware to the strictest global requirements, it may impact everyone. What counts as radio equipment? Everything from WiFi routers to wearables, SDR dongles to shortwave radios.

The idea is to prevent rogue reconfigurable radios from talking over each other, and prevent consumers from bricking their routers and radios. Before SDR was the norm, and firmware was king, it was easy for regulators to test some hardware and make sure that it’s compliant, but now that anyone can re-flash firmware, how can they be sure that a radio is conformant? Prevent the user from running their own firmware, naturally. It’s pretty hard for Hackaday to get behind that approach.[]

WSPR explained

Many thanks to SWLing Post contributor, Bill Patalon, who shares a link to the following article on Extreme Tech:

Last Tuesday at 1744 UTC (1:44 PM EDT) UR3RM, a ham radio station in Ukraine blindly sent out a message on 7040.138 kHz.  It was automated. It was text. Maybe someone would hear it. Maybe not.

The “maybe not” part is easy to understand because UR3RM’s transmitter was putting out one milliwatt, .01 watts. To put that in perspective, a Class 2 Bluetooth transmitter, the ones good for around 30 feet, run 2.5 milliwatts.

UR3RM was using a mode called WSPR for Weak Signal Propagation Reporting. Unlike most of ham radio, this is a one-way mode. Not only is there little expectation anyone will be listening, but there’s even less that the signal would make it back. Radio propagation isn’t always a two-way path.

WSPR’s biggest selling point is you can do it on the cheap. It’s easy to set yourself up for not much more than $100 and often a whole lot less. And, though a ham radio license is needed to transmit, anyone can put up a receiver. And the US ham license test is multiple-choice, all published and online.[…]

HAARP WSPR 80m transmissions July 30 – Aug 1

(Source: Southgate ARC)

Chris Fallen KL3WX will be using 80 kilowatts into the massive HAARP antenna array in Alaska for WSPR experiments in the 80m band from July 30 to August 1

Chris KL3WX tweeted:

WSPR experiments are tentatively planned to occur between 2300 and 2400 hours UTC on July 30, 31, and Aug 1. Most broadcasts will be at the 80m dial frequency default in WSJT, that is 3.5926 MHz with AM (3 dB loss) because HAARP does not have an upper side band (USB) mode yet!

Video: Lightbulb vs Radio Beacon by Thomas Cholakov (N1SPY)

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

My 11 year old son Tommy (N1SPY) completed a project where he compared a 1W lightbulb to a .25 W radio beacon that he put together and bet that the radio beacon can be heard around the world. I asked him to document his activities as he went along. The project took a couple of months but is now complete and we stitched together a video of his activities.

Wow–Tommy, you’ve done an amazing job here!

I especially like how you’ve taken time to explain the principles behind the various steps of the process. Brilliant job!

Tommy, your future videos are always welcome here. Keep up the good work and we’d love to hear how many new countries you’ve racked up on your WSPR system!
