Agents operate on both coasts
Even as the Federal Communications Commission and Department of Justice prepped to take significant action against alleged pirate operators in Manhattan, it had its eye on other operations in New York, New Jersey and Oregon.
In early April, agents from the New York Office of the Enforcement Bureau investigated an unlicensed FM station operating on the frequency 107.7 MHz in the Orange, N.J., area. Using direction-finding techniques, radio signals were detected on the frequency 107.7 MHz from a property on 439 Main Street and found that the alleged station was being operated by Nicolas Ronald at a property owned by Sanjiv Jain of Orange.
Around the same time, agents from the Boston Office investigated a complaint of an alleged unlicensed FM station operating on the frequency 99.7 MHz in Brockton, Mass. Agents delivered a notice of unlicensed operation to Cayemite J. Edner of Brockton as the owner of the property on North Warren Ave. where the station was allegedly operating.
The month prior, agents sent a notice of unlicensed operation to John G. Pierre of Brooklyn after agents responded to complaints of an unlicensed FM station operating on the frequency 93.7 MHz. Agents confirmed by direction-finding techniques that radio signals on frequency 93.7 MHz were allegedly emanating from 1710 Carroll Street, and that Pierre was the operator of the station.
[Read: Feds Confiscate Gear From Alleged NYC Radio Pirate]
About 2,600 miles across the country in La Grande, Ore., agents from the Portland office of the Enforcement Bureau used direction-finding techniques to assess that radio signals on frequency 92.3 MHz were allegedly emanating from an antenna located in Room 8 at the Orchard Motel occupied by Thomas Eugene Barnes.
In each case, agents allegedly discovered that the stations were operating at a strength that exceeded the maximum permitted level of 100 microvolts per meter (μV/m) at 3 meters for nonlicensed devices.
Each were warned that operating radio transmitting equipment without a valid radio station authorization is a violation of Federal law, and that an operator may be subject to monetary fines and criminal sanctions. Each individual has 10 days to respond with evidence they have FCC authority to operate.

Hu Chaoran BG2CRY tests 435/2250 MHz dish feed for DSLWP ground station — Image credit Wei Mingcchuan BG2BHC
DSLWP is a lunar formation flying mission led by Harbin Institute of Technology for low frequency radio astronomy, amateur radio and education. It consists of a pair of 47 kg microsatellites launched from the Xichang Space Center into a lunar transfer orbit at 21:28 GMT on Sunday, May 20, 2018 and they will enter a 300 x 9000km lunar elliptical orbit. Onboard each satellite, there are two VHF/UHF SDR transceivers to provide beacon, telemetry, telecommand, digital image downlink and a GMSK-JT4 repeater. Onboard transmitting power is about 2 watts.
Update May 21, 2018: After deployment signals from the DSLWP satellites were received by Edson Pereira PY2SDR, Nicolás Castro CD3NDC, Robert Mattaliano N6RFM and many other radio amateurs around the world.

Wei Mingchuan BG2BHC reports the first launch window will open at about 21:28 GMT Sunday, May 20. The transmitters will be activated soon after separation. Satellite A will transmit 500 baud GMSK with 1/4 turbo code on 435.425 MHz and 250 baud GMSK with 1/2 turbo code and precoder on 436.425 MHz, and satellite B will transmit 500 baud GMSK with 1/4 turbo code on 435.400 MHz and 250 baud GMSK with 1/2 turbo code and precoder on 436.400 MHz, in every 5 minutes by default. Each transmission will last about 16 seconds. Radio amateurs in South America will have the earliest chance to receive the signals from the satellites, then North America, Oceania, Asia, Europe and Africa.
Harbin Institute of Technology Amateur Radio Club expects radio amateurs to join in this mission. We will prepare different QSL cards for different flight phase for amateurs successfully made QSO or received telemetry. Awards will also be given to the first 10 amateurs in each continent who successfully decoded the signals from the satellites, received the most number of packets, or received an image. Your participation will also help the team to get a better knowledge of the status of the satellites.
An open source decoding software based on GNU Radio to work with RTL-SDR and USRP is provided. Not difficult to change the grc files to support other SDR receivers. A small proxy software will send the decoded data to a server for real-time display.

Daily DXER ham radio news
In public, he is known as Harold Lloyd. On the radio waves, his call sign is W4OE.
For more than a decade, the Village of Glenbrook resident has donated his knowledge of being a ham radio operator to Sumter County Emergency Management.
“I’ve enjoyed being able to provide a service to the community,†Lloyd said.
In February, the members of emergency management recognized Lloyd for his work with Skywarn, a program of the National Weather Service in which ham radio operators relay information about severe weather in their particular area. While he is stepping away from working with Skywarn, he will continue to assist emergency management.
“He’s been our strongest supporter going way back,†said David Casto, director of emergency management in Sumter County. “We’re proud of him. He’s done so much for the county and others, and he’s still going strong.â€
Since 2002, Lloyd, who also is president of The Villages chapter of the Quarter Century Wireless Association, has done everything from being the emergency coordinator of the volunteers on several occasions to helping out with training and serving as one of the group’s technical experts.
“He can take something complex and make it simple for me,†Casto said.
Lloyd has established nets, or on-the-air gatherings of operators relaying information about any inclement weather in the area. Twice a week, Lloyd has led these nets as a communications drill to make sure everything is ready in case an emergency occurs.
When Hurricane Irma came through the state last year, Lloyd said, the volunteers were on duty for quite a few hours.
“We do what we have to do,†Lloyd said. “You’re never prepared enough. You can have all the training, but you’re doing something you’re not prepared for. You hope the training you had keeps you through that.â€
Ham radio comes into play when major forms of communication become overwhelmed. If cellphone towers lose their signals or if too many people try to use their phones at once, it causes the system to shut down.
Ham radio operators can plug their equipment into a generator to send out messages between individuals.
“We provide the communication,†Lloyd said.
Lloyd’s introduction to the world of ham radio switched on some 60 years ago.
When he was 14 living in Kirksville, Missouri, his family had a large Philco radio that picked up various bands. One day, Lloyd was pushing buttons and turning the dial when he came across people carrying on a conversation.
“I thought, ‘What is this?’†Lloyd said.
Lloyd’s father revealed that Lloyd was hearing ham radio operators.
In 1952, Lloyd got a novice radio license from the Federal Communications Commission office in Kansas City, Missouri, and jumped into the world of ham radio with both feet.
His first receiver was a National NC-101X, which he said was 76 pounds, what he called “a big one.†He thinks he may have made his first call to someone in Iowa.
He discovered learning the ins and outs of ham radio to be quite technical.
“There are a lot of terms you have to know,†Lloyd said. “There are a lot of electric principles. Algebra was a help.â€
Some 40 years later, when Lloyd was living in Canton, Georgia, he became an Amateur Radio Emergency Service coordinator for Cherokee County, thanks to a couple of members recruiting him.
“I volunteered without knowing what I was volunteering for,†Lloyd said.
After moving to Florida, he wanted to continue his newfound endeavor.
Whenever he is finished helping out with severe weather situations in the Sumter County EOC, Lloyd said he feels more tired than tense.
“You have to be alert,†Lloyd said. “There’s a feeling of accomplishment of helping. It’s something you look forward to.â€

China has launched two microsatellites into a lunar transfer orbit. They launched as secondary payloads with the Quequiao relay satellite on May 20, in conjunction with the Chang’e 4 mission to the far side of the moon. Once in lunar orbit, DSLWP-A1 and DSLWP-A2 (DSLWP = Discovering the Sky at Longest Wavelengths Pathfinder) — also known as LLongjiang-1 and Longjiang-2 — will test low-frequency raddio astronomy and space-based interferometry. They carry Amateur Radio and educational payloads, but not a transponder. The Chang’e 4 mission will be the first-ever attempt at a soft landing on the far side of the moon.
Following deployment, signals from the DSLWP satellites were received by radio amateurs in Brazil, Chile, and the US, as well as by many others around the world. Harbin Institute of Technology (BY2HIT) developed and built the DSLWP spacecraft and is overseeing that mission. The two microsats eventually will enter a 300 Ã — 9,000 kilometer elliptical orbit. Each satellite carries VHF/UHF SDR transceivers for beacon, telemetry, telecommand, and digital image downlink, plus a GMSK-JT4 repeater. Onboard transmitting power is about 2 W.
The astronomy objectives of the two spacecraft are to observe the sky at the lower end of the electromagnetic spectrum — 1 MHz to 30 MHz — with the aim of learning about energetic phenomena from galactic sources, using the moon to shield them from earthbound radio signals.
An open telecommand protocol on the spacecraft is designed to allow radio amateurs to send commands to take and download images. DSLWP-A1 downlinks are 435.425 MHz and 436.425 MHz; DSLWP-A2 downlinks are 435.400 MHz and 436.400 MHz. They will use 250/500 bps GMSK using 10 kHz wide FM single-channel data, with concatenated codes or JT4G. JT4 uses four-tone FSK, with a keying rate of 4.375 baud; the JT4G sub-mode uses 315 Hz tone spacing and 1,260 Hz total bandwidth.
The Queqiao communications relay satellite is required for the lunar far-side landing to facilitate communication with a not-yet-launched lander and rover because the moon’s far side never faces Earth, and some significant scientific measurements from the dark side of the moon require real-time contact with Earth. Queqiao was developed by the China Academy of Space Technology (CAST).
Harbin Institute of Technology Amateur Radio Club hopes that radio amateurs will get involved with the DSLWP mission, and QSL cards have been designed for different flight phases for amateurs who successfully receive telemetry or make contact.
