SSTV Fiesta 2022

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

For those who’d like to try receiving SSTV images and also get into the holiday spirit, there is an annual SSTV Fiesta from December 12, 2022 to January 6, 2023. The Fiesta is sponsored by the Azteca DX’ers. The frequencies are 14.230 MHz in the 20m amateur band and 27.700 MHz, just above the US Citizen’s Band.

An excellent decoder is MMSSTV available free on line.

I’ve monitored 27.700 MHz the past week and have decoded the images below using an Airspy HF + Discovery, 31 foot ground mounted vertical, MMSSTV software and VB cable for piping the audio from the Airspy to MMSSTV.

Note that you have to set your receiver to USB. With MMSSTV you can set your receiver on the frequency of choice and just walk away like I did and the software will store any images received. Image clarity depends on propagation, just like other modes.

Good luck, thanks go out to the Azteca DX’ers for this enjoyable event and 73’s.

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!

Defined By Scandal At Voice of America, CEO Resigns At Biden’s Request (NPR)

Michael Pack resigned Wednesday as the CEO of the federal agency over the Voice of America and other federally funded international broadcasters after a turbulent seven-month tenure. He leaves the U.S. Agency for Global Media with a Trumpian legacy of ideological strife, lawsuits and scandal, his departure effective just two hours after the swearing-in of President Biden, who requested him to leave.

Biden has named senior VOA news executive Kelu Chao as acting CEO.

Pack came to lead the U.S. Agency for Global Media with the support of former President Donald Trump; his appointment was delayed more than two years in the U.S. Senate by lawmakers who feared he was too ideological and also who questioned his finances. The soft-spoken conservative documentary maker proved to be an ideological warrior in the mold of his patron, taking to one conservative news outlet after another to denounce his own staff, all in the name of fairness.

In his resignation letter, Pack said he was “solely focused upon reorienting the agency toward its missions.” And he attacked the request for his resignation as “a partisan act,” saying the leadership of the agency and its networks “is meant to be non-partisan, untethered to alternations in the political regime.”

He added, “I had no political agenda coming into USAGM, and I still do not have one.”

NPR conducted scores of interviews over the controversies Pack’s actions engendered. And few at the agency or its broadcasters agreed with Pack’s characterization of his mission or performance, instead characterizing him as seeking political control over their coverage. Just last week, a VOA reporter’s insistent questions to then-Secretary of State Mike Pompeo and VOA Director Robert R. Reilly over the siege on Congress after a public event led to her demotion and an investigation.

Pack routinely accused journalists of anti-Trump bias, sought to fire top executives as part of a “deep state,” ominously accused the networks of being receptive to foreign spies and denied requests for visa extensions from his own staffers who are foreign nationals.[]

FCC Issues Enforcement Advisory: Radio Users Reminded Not to Use Radios in Crimes (ARRL News)

The FCC has released an Enforcement Advisory for licensees and operators across radio services.

[Complete text of FCC Enforcement Advisory follows.]

FCC ENFORCEMENT ADVISORY

TV Detector Vans Once Prowled The Streets Of England (Hackaday)

The United Kingdom is somewhat unique in the world for requiring those households which view broadcast television to purchase a licence for the privilege.

Initially coming into being with the Wireless Telegraphy Act in 1923, the licence was required for anyone receiving broadcast radio, before being expanded to cover television in 1946. The funds generated from this endeavour are used as the primary funding for the British Broadcasting Corporation.

A typical TV licence invoice. Separate licences for black and white and color sets still exist, with 6000 B&W licences issued in 2019.

Of course, it’s all well and good to require a licence, but without some manner of enforcement, the measure doesn’t have any teeth. Among other measures, the BBC have gone as far as employing special vans to hunt down illegally operating televisions and protect its precious income.

THE VAN IS COMING FOR YOU

To ensure a regular income, the BBC runs enforcement operations under the TV Licencing trade name, the entity which is responsible for administering the system. Records are kept of licences and their expiry dates, and investigations are made into households suspected of owning a television who have not paid the requisite fees. To encourage compliance, TV Licencing regularly sends sternly worded letters to those who have let their licence lapse or have not purchased one. In the event this fails, they may arrange a visit from enforcement officers. These officers aren’t empowered to forcibly enter homes, so in the event a homeowner declines to cooperate with an investigation, TV Licencing will apply for a search warrant. This may be on the basis of evidence such as a satellite dish or antenna spotted on the roof of a dwelling, or a remote spied on a couch cushion through a window.[]

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!

Ham radio operators honor legacy of Mars Hill company (Citizen Times)

During the 1950’s and ’60’s, when the Hammarlund Manufacturing Company had a factory just west of Mars Hill College, the town could have been considered a world center of advanced electronic technology. With a company motto of “Quality Without Compromise,” almost 90% of American WWII wartime military electronic equipment employed Hammarlund capacitors. They also built U.S. Navy search radar installed on aircraft carriers, battleships and cruisers.

Hammarlund was one of the three leading brands of radio communications equipment at the time, along with Hallicrafters and Collins Radio. These three companies dominated in providing state of the art electronics equipment to the U.S. military, large and small corporations, and to private individuals who had the means and taste to own the very best.

Hammarlund Radio initially operated out of New York City starting in 1910, in the early days of radio. They began consolidating all of their operations in Mars Hill in 1951, in a newly constructed facility that spread out to over 100,000 square foot on Hammarlund Drive — now named Hickory Drive. The site employed hundreds from around the area and their work lives on today. []

FM Radio From Scratch Using An Arduino (Hackaday)

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more culturally relevant.

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage conversion that isn’t necessary with AM. For this build, [hesam.moshiri] uses a TEA5767 FM chip because of its ability to communicate over I2C. He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a small LCD screen which displays the current tuned frequency. With the addition of a small 5V power supply, it’s a tidy and compact build as well.[]

2016 Report Confirmed Problem of Political Bias At Voice of America (USAGM Watch)

by Dan Robinson

Trump USAGM CEO Michael Pack Was Attacked For Attempts to Focus on Problem

It was May of 2016 and Amanda Bennett was only a few weeks into what would become a nearly four year stint as director of the Voice of America, among the “plum” jobs in Washington, D.C.

Bennett was just getting her feet wet, and at the time was dependent on a group of longtime embedded VOA managers that she would at one point describe as a “fantastic leadership team.”

She had received fair warning, from former VOA employees and extensive reporting by the independent watchdog website BBG and USAGM Watch, of disturbing issues at VOA, located in what has long been one of the most dysfunctional of federal agencies.

Some VOA journalists were using their taxpayer-funded positions to engage in self-promotion and campaign for political causes, a fact little known to most Americans. VOA’s website and digital operations were plagued by failures in breaking news coverage, and inaccuracies in content.

Both VOA and what was then called the Broadcasting Board of Governors (BBG) were increasingly seen by U.S. lawmakers as moribund. A Republican-led and eventually bipartisan effort in Congress proposed major restructuring – there was little patience left on Capitol Hill where the agency was increasingly considered to be “broken,” “rudderless,” and “worthless.” President Obama signed the reform legislation in December 2016 to create a powerful agency CEO position and to make the BBG Board purely advisory.[]

ARISS Slow Scan TV event (Southgate ARC)

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) for late December. This will be a special SSTV event to celebrate the 20th anniversary of ARISS.

The event is scheduled to begin on December 24 and continue through December 31.

Dates are subject to change due to ISS operational adjustments.

The Geminids – a reminder (Southgate ARC)

The Geminids are a prolific meteor shower caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid with a “rock comet” orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet.

They are the biggest meteor shower of the year, and normally occur between 4 December – 17 December.

The peak is expected on 14 December.

Expect FM “pings” and hopefully interesting dx opportunities.

Mike

Bill recommends Slow Scan Radio

Many thanks to SWLing Post contributor, Bill Hemphill (WD9EQD), who writes:

I have enjoyed listening to Scow Scan Radio SWL Program.

I used a WebSDR to receive it.

http://www.slowscanradio.com/

But it has been off the air for the past weeks due to some minor health issues. The program was interesting in that besides Slow Scan photos, he also did other digital modes using FLDigi.

Some of the test included multiple digital signals in the same waterfall.

When I went to website today to check to see if there were any updates on when it might return to the air, I discovered that he is doing a podcast: Daily Minutes Podcast. Following is podcast feed:

https://dmpodcast.net/feed/

This podcast is a combination of new items as well as some re-runs of earlier Show Scan Radio programs. They also are a combination of English & Dutch. The June 13 & 14 podcasts are about off-shore radio. Very interesting and enjoyable.

The Jun 12 & 14 podcasts include a re-run of an earlier Slow Scan Radio Show in the last thirty minutes of the podcast.

[The screen shot at the top of the page is a] sample of the start of the digital portion.

Very cool! Thank you for sharing this, Bill!

April 9th – 23rd, 2019: Transmitting Reykjavik Museum of Photography glacier images via HF SSTV

One of the images to be transmitted: Image 1 ~ 1955-1970, Þórsmörk. A lightly dressed elderly man looks at Eyjafjallajökull glacier

Many thanks to Lucy Helton (KD2MFV) who writes:

Dear Thomas,

Between April 9th – 23rd 2019, I’m artist-in-residence at SIM, in Reykjavik, Iceland, to partner with Jón Þ Jónsson, TF3JA, an Icelandic Radio Amateur and member of Icelandic Radio Amateurs ÍRA, to transmit images via SSTV . The images, appropriated from the Reykjavik Museum of Photography’s collection, are of Icelandic glaciers photographed in a time before we knew climate change existed. I’m asking HAM radio operators who receive my long-range image transmissions, to print out the images received and mail them back to me, using instructions on my website (www.lucyhelton.com). I will be updating the blog daily.

In exchange, when I have assembled the printed pieces to reconstruct the whole image transmitted, I will make QSL postcards of the completed images and mail them back to the participating HAMs. The resulting artwork will be a collaborative fine art example of long-range communications between humans, concerning accelerated environmental change.

I would greatly appreciate it if you could please notify HAM’s of the existence of this project by announcing it on the blog?

Transmissions

Each single transmission consists of 12 x SSTV images. I will be transmitting 5 different glacier images over 15 days.

SSTV calling frequency and daily transmission times are (the frequency will be + / – 5kHz):

20 meters: (USB) 14.230 MHz @ 1pm / 6pm / 11pm GMT

International Space Station SSTV Event Feb 15-17

(Source: Southgate ARC)

Space Station Slow Scan TV Event Feb 15-17

ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events from the International Space Station on February 15-17

Transmissions on 145.800 MHz FM are scheduled to begin Friday, Feb. 15 at 08:45 UT and run through Sunday, Feb. 17 at 17:25 UT.

SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using Twitter or Instagram.

When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.800 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.

Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.
wordpress.com/
). In additional, four ARISS commemorative images will also be included.

Once received, Images can be posted and viewed by the public at
http://www.spaceflight
software.com/ARISS_SSTV/index.php

In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the ARISS Twitter feed @ARISS_status or the AMSAT Bulletin Board

The SSTV images will be transmitted in PD-120 on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.
