(June 30, 2016) The Society of Broadcast Engineers (SBE) has had concerns about increases in ambient noise, especially in the AM broadcast band, and have received a response from the FCC. As reported earlier, on June 15, 2016, the Commission issued public notice DA 16-676 announcing that its Technological Advisory Council (TAC), an FCC advisory group, will investigate … [Read more...]
FAA Releases Commercial Drone Rules
(June 21, 2016) The first operational rules for routine commercial use of small unmanned aircraft systems (UAS or “drones”) has been finalized by the Department of Transportation’s Federal Aviation Administration. “We are part of a new era in aviation, and the potential for unmanned aircraft will make it safer and easier to do certain jobs, gather information, and deploy … [Read more...]
Juno Makes Successful Orbital Maneuver Around Jupiter
(July 4, 2016) Launched from Earth in 2011, the Juno spacecraft performed a successful orbital burn July 4th and will study the giant planet from an elliptical, polar orbit. Juno will repeatedly dive between the planet and its intense belts of charged particle radiation, coming only 5,000 kilometers (about 3,000 miles) from the cloud tops at closest approach. According to … [Read more...]
South African EMC Compliance Outlined
Manufacturers and importers of electronic equipment can expect a “transparent, predictable and efficient process” when applying for Electromagnetic Interference/ Compatibility (EMI/EMC) Certificates of Compliance (CoCs), South African Bureau of Standards (SABS) CEO Dr. Boni Mehlomakulu said.A memorandum of understanding (MOU) between the SABS and the Independent Communications … [Read more...]
New Affordable Pulse Generator
The AIM-TTi TGP3100-Series are pulse generators that can replicate the capabilities of traditional pulse generators while adding many additional facilities such as pulse modulations. The instruments can also act as high performance noise generators and as function/arbitrary generators. Some of its features include: pulse waveforms from 1mHz to 50MHz [25MHz], with minimum rise … [Read more...]

Russia Seeks Invisible Air Defense Missiles
(June 16, 2016) Recently the Russian newspaper, Izvestia, reported that Russia wanted to hide its most sophisticated air defense missiles from U.S. spy satellites and spy planes by using containers that block the emission of electromagnetic pulses caused when operating electronic equipment. Citing an anonymous Ministry of Defense source, the Russian newspaper said the S-400 … [Read more...]
FCC Takes First Steps in Approving Wireless Medical Body Sensors
(June 21, 2016) U.S. healthcare facilities are getting closer to making Medical Body Area Networks (MBANs) a reality. A new website has been launched so hospitals can formally register their deployments of MBANs, which support wireless patient monitoring to transmit patient health data over a short range at low power levels. The U.S. is the first country to allocate spectrum … [Read more...]
FCC Wants Your Help Understanding Spectral Noise Floor
(June 15, 2016) The US Federal Communications Commission is trying to figure out exactly how much trouble is being caused by product emissions that effectively raise the overall noise floor over the frequency spectrum. Among the amateur radio and shortwave listener communities, the noise floor in the radio spectrum has obviously been rising as the number of devices in use that … [Read more...]
