Many thanks to SWLing Post contributor, Pete Eaton, who writes:

Don’t know if you are familiar with this project, a full blown 5 watt HF SDR Transceiver for less than $300!

No sound cards, DUC/DDC architecture.

Here’s the project description by Steve Haynal via YouTube:

The Hermes-Lite is a low-cost direct down/up conversion software defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. It is entirely open source and open hardware, including the tools used for design and fabrication files. Over 100 Hermes-Lite 2.0 units have been successfully built.

Court Finds RM Broadcasting Must Register as a Foreign Agent

Many thanks to SWLing Post contributor, Ed, who shares this update regarding RM Broadcasting:

Court Finds RM Broadcasting Must Register as a Foreign Agent

U.S. District Court Judge Robin L. Rosenberg has ruled that a Florida-based company, RM Broadcasting LLC (RM Broadcasting), was acting as an agent of a foreign principal and must register as such under the Foreign Agents Registration Act of 1938 (FARA).

The Department of Justice contended in a civil counterclaim that RM Broadcasting has been acting as an agent of the the Federal State Unitary Enterprise Rossiya Segodnya International Information Agency (Rossiya Segodnya), a Russian state-owned media enterprise created by Vladimir Putin to advance Russian interests abroad. The litigation marked the first FARA civil enforcement action since 1991. Assistant Attorney General for National Security John C. Demers and U.S. Attorney Ariana Fajardo Orshan for the Southern District of Florida made the announcement.

“The American people have a right to know if a foreign flag waves behind speech broadcast in the United States,” said Assistant Attorney General Demers. “Our concern is not the content of the speech but providing transparency about the true identity of the speaker. This case shows that the Department can and will utilize all of its tools to bring transparency to efforts by foreign entities to influence the American public and our government, and demonstrates our renewed effort to enforce FARA rigorously.”

“While the right to free speech remains paramount to our democracy,” U.S. Attorney Ariana Fajardo Orshan said. “FARA ensures that the American public is fully cognizant of the true source of the messages broadcast in the United States. Armed with full information, Americans may properly evaluate the value of the speech they hear. As such, FARA is a fundamental tool in our continuing efforts to defend our democracy.”

In November 2017, RM Broadcasting and Rossiya Segodnya entered into a services agreement pursuant to which RM Broadcasting would provide for the broadcast of Rossiya Segodnya’s “Sputnik” radio programs on AM radio channel 1390 WZHF in the Washington, D.C. region. Under this agreement, RM Broadcasting could not alter Rossiya Segodnya’s radio programs in any way. As the services agreement established Rossiya Segodnya’s direction and control over RM Broadcasting, the FARA Unit of the National Security Division informed RM Broadcasting that it was acting as a publicity agent and an information-service employee of Rossiya Segodnya and was required to register as an agent of a foreign principal.

RM Broadcasting initiated the proceeding in the Southern District of Florida seeking a declaratory judgment that it did not have to register as an agent of a foreign principal. The Department responded by filing a counterclaim seeking an injunction to require RM Broadcasting to register. Earlier this week, the court granted the Department’s motion for judgment on the pleadings. A final judgment directing RM Broadcasting to register under FARA is expected.

This case was handled by Assistant U.S. Attorney Matthew J. Feeley and Trial Attorney Nicholas Hunter of the National Security Division’s Counterintelligence and Export Control Section.

About FARA

The purpose of FARA is to protect the national defense, internal security, and foreign relations of the United States by requiring public disclosure by persons engaging in political activities and other activities for or on behalf of foreign governments, foreign political parties and other foreign principals so that the Government and the people of the United States may be informed of the identity of such persons and may apprise their statements and actions in the light of their associations and activities.

Cyclone Fani: How Ashok prepared for this powerful storm

Category 4 Cyclonic Storm Fani was the strongest tropical cyclone to strike the Indian state of Odisha since Phailin in 2013.

Many thanks to SWLing Post contributor, Ashok Shankar Das, who shares the following post from his blog SWLDAS:

The extremely severe cyclonic storm #Fani recently visited Odisha. It is Peculiar to have a Cyclone in this time of year. Though history says earlier there are some cyclones hit Odisha coast during this summer season.

[…]I have seen several Cyclones including #1999SuperCyclone . Though Super cyclone has done a lot of damage, this one is no less. Wind speed of 200kmph with gust 220 to 250 kmph ripped everything in its path. major damages to infrastructures like power grids, cell towers under construction buildings are name a few.

My Preparedness

The CountyComm GP5-SSB

See this SWLING article–I was runner-up in that challenge. My preparation for Cyclone Fani was as per I have described. Well Not all. I have charged emergency light, arranged candles and lantern. Stocked Biscuits and Flat rice. Stored around 15Liters of drinking water. Emergency medicines and fully Charged 3 Baofeng Walkie Talkies.

The GP5SSB I got as a gift from SWLING Post, put new battery in it. I have downed external antennae for HF and VHF. Baofeng handys are quite good as scanner. I monitored HAM band so I could know the situation in surrounding area and also if situation arises I could give a distress call to Nearby monitoring person. But that situation didn’t arise.

HAM volunteers from WBRC started their communication service since 5th May. They Have setup a VHF in state control room at Bhubaneswar, ADM office Puri and Khurda.
Since 5th may onward I was monitoring and in QSO with VU2IPL(Suresh). VU2FTP VU2XRY VU3YDA and VU3OXI are handling the communication between Puri, Khurda and Bhubaneswar.[…]

Thank you for sharing this, Ashok and we’re very pleased that you made it through this extremely dangerous storm well-prepared. It sounds like your community has a good ham radio communications network at the ready as well.

Ashok, you are reminding me that it’s time to dream up another Virtual Radio Challenge along with an enticing prize. I’ll start putting one together! Perhaps I can find a prize at the Hamvention this week. Stay tuned…

Photo Tour: The Edward R. Murrow Transmitting Station

Yesterday, I posted a photo and asked if you guess where I was when I took the shot.

Those of you who guessed the Edward R. Murrow Transmitting Station (formerly, “VOA Site B”) near Greenville, North Carolina, were absolutely correct!

My buddy, John Figliozzi, gave a presentation about NASWA and the Winter SWL Fest at the NASB (National Association of Shortwave Broadcasters) which was held in the Raleigh area, May 9th and 10th. Due to a conflict, I was not able to attend the NASB meeting this year, but I did arrive at the conference hotel late Thursday where I met a handful of attendees. I had previously invited John to join me on the station tour, and he was quite happy to do so!

Macon Dail (WB4PMQ), the transmitting station’s Gold Medal award-winning Chief Engineer, made time to give us a tour Friday, May 10, 2019.

And now, on to the photo tour of this remarkable facility.  My inclination is to caption each photo…but I know if I attempt this, I won’t post this gallery for several months!  Instead, I’ll roughly divide the photos by the various sections of the site. Note, however, that there are more than one hundred photos in this detailed post––to decrease its length, some of the photos have been placed in clickable thumbnail galleries. Those of you who receive the SWLing Post as an email digest, I would strongly encourage you to view this post directly on our website, so all of the gallery images will appear.

Enjoy!

Station entrance, lobby, and library

The Front Lobby

In this photo, Macon is showing John one of the notebooks, which is chock-full of reception reports from listeners. This notebook, as you can see, is prominently displayed in the front lobby.

We found our friend Rich D’Angelo in the stack of reception reports.

In a mezzanine above the control room, there is a space that houses a library, a presentation/classroom area, and even a small workout/fitness room.

View into the control room from the mezzanine.

Tubes glowing in the active GE transmitter!

Very high voltage in this power room for the GE transmitters.

Installing new transmitters

Macon and his team are in the process of installing modern transmitters sent from other IBB sites. As you might imagine, this is a tedious process, and requires highly-skilled technicians.

 

 

Power

Antenna switching bay and feed lines

In this photo, we’re looking straight down a 50 kW feed line in conduit which leads to the switching bay. Normally, this would not be accessible, but this line is being built for a new transmitter.

The antenna switching bay is truly massive…

View from the observation tower

Wow, what a tour…

John and I enjoyed our in-depth tour of the Edward R. Murrow Transmitting Station! The staff, as always, were incredibly welcoming and accommodating.

I believe this was my fourth tour; nonetheless, I still discovered new things, and it’s no wonder. The staff of the station are constantly upgrading, updating, and tweaking the performance of their equipment. This is the reason their signals are always full-fidelity and crystal-clear on the air.

I’m simply amazed by all they accomplish.  Keeping this station running is certainly a labor of love.

Of course, this won’t be my last visit to the station.  I fully intend to return, if not later this year, at least next, to check out the new transmitters in operation.  Stay tuned! To this active VOA station.
