Amateur radio (also called ham radio) is the use of designated radio frequency spectra for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. The term “amateur” is used to specify persons interested in radio technique solely with a personal aim and without direct monetary or other similar reward, and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government’s radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. According to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio.[1] About 830,000 amateur radio stations are located in IARU Region 2 (the Americas) followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about 750,000 stations. A significantly smaller number, about 400,000, are located in IARU Region 1 (Europe, Middle East, CIS, Africa).

RTL-SDR’S WITH THE R820T2 TUNER AND 2X TELESCOPIC ANTENNA

R820T2 RTL-SDRs on Amazon.com (currently for US customers only sorry!) and are currently running a $2 off promotional sale which will expire January 31, or until the first batch of stock runs out. Compared to the other choices our RTL-SDR Blog branded units come with several improvements which we list below.

  • Use of the R820T2 tuner which has been shown to have slightly better noise performance and give better SNR compared to the standard R820T chip.
  • Use of improved component tolerances which help the circuit to operate at its optimum.
  • Use of a surface mount 28.8 MHz oscillator instead of the “can” type. We believe this will reduce the PPM offsets to below 30 in most dongles, but note we can not guarantee this.
  • Improved “full braid” coax cable on the antenna base which has significantly lower loss compared to the coax used on other brand RTL-SDR stock antennas.
  • Comes with 2 x telescopic antennas. 1 x 9.5 cm to 31.5 cm telescopic antenna and 1 x 20 cm to 1.5 m telescopic antenna. Great for beginners to receive a wider range of frequencies without buying extra antennas.
  • No IR LED. The IR LED is useless for SDR operation and the long legs on the LED may pick up interference.

Motorola Solutions Files Patent Infringement Trade Secret Misappropriation

Motorola Solutions Files Patent Infringement and Trade Secret Misappropriation Complaints Against Hytera Communications


Patent Infringement and Trade Secret Misappropriation Complaints Filed in U.S. District Court

Motorola Solutions is Committed to Protecting its Valuable Intellectual Property Against Illegal Infringement and Copying

CHICAGO – March 14, 2017 – Motorola Solutions, Inc. (NYSE: MSI) (“Motorola Solutions” or the “Company”) today announced it has filed complaints in the U.S. District Court for the Northern District of Illinois against Hytera Communications Corporation Limited (SHE: 002583) (“Hytera”) of Shenzhen, China. The complaints assert that Hytera’s two-way radios, base stations, repeaters and dispatch systems, as well as its related commercialization and sales activities, are infringing patents owned by Motorola Solutions and utilizing stolen Motorola Solutions trade secrets.

Motorola Solutions believes that Hytera is intentionally infringing its intellectual property and misappropriating its trade secrets, which has enabled Hytera to compete unfairly by bypassing investment in innovation.

Mark Hacker, general counsel and chief administrative officer of Motorola Solutions, said, “Motorola Solutions has a long and distinguished track record of developing industry-leading products and technologies, reflecting our significant investments in research and our commitment to innovation. We are proud to have built an extensive portfolio of more than 4,000 patents, including the patents at issue in these lawsuits, which were developed by Motorola Solutions’ world-class engineers.”

Mr. Hacker continued, “We believe it is clear, and we are confident the Courts will agree, that Hytera’s product portfolio and marketing materials are based on Motorola Solutions’ proprietary intellectual property. Brazen copying and blatant, willful infringement of this sort create an unfair playing field and threaten the industry’s ability to innovate. We will use every means available to vigorously defend the Company’s valuable intellectual property, while continuing to drive innovation and technical excellence for the benefit of our customers around the world.”

Hytera’s illegal behavior was assisted by three engineers who resigned from the Company to join Hytera, where they had key roles in developing Hytera’s infringing products using misappropriated Motorola Solutions technologies and continue in senior-level positions today. In the period leading up to their resignations, through a series of serious misrepresentations and carefully planned illegal acts, these engineers maliciously accessed, downloaded and transferred more than 7,000 highly confidential files related to Motorola Solutions’ technologies, including confidential technical, marketing, sales, legal and other types of trade secret materials. Subsequently, Hytera began illegally manufacturing and marketing a line of products and technologies containing technologies invented, designed, developed and in some cases patented by Motorola Solutions.

Motorola Solutions is seeking to enjoin Hytera’s continued infringement and misappropriation by stopping its sales of key products in the United States and importation of those infringing products into the United States. The Company is committed to ensuring that its intellectual property rights are protected around the world.
