He emigrated in 1884 to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed.

  • Radio Control System
    Radio Control System The Radio Control System consists of the control transmitter unit held by the operator and the receiver with its associated components in the robot. The Radio Control Transmitter converts movements of the control sticks and switches into a coded radio signal, which is transmitted by radio to the Radio Control Receiver within the robot. The signal is received and then decoded by the micro-controller, which is on the main circuit board in the robot. The micro-controller controls functions based on what was sent from the radio control transmitter. RADIO CONTROL OPERATING INSTRUCTIONS Refer to the diagram showing the radio control transmitter for the location of controls. Check all of the trim adjustments on the transmitter and make sure they are in their center position. Extend the Radio Control Transmitter Antenna 1/4 to 1/2 way. Turn the Radio Control Transmitter on first and then turn on the main robot power switch. It is necessary for the robot to always have an operating signal when it is on, if there is no signal you will not have full control of the robot. The right hand joystick controls movement of the robot's drive wheels. Pushing the stick forward will cause the robot to move forward. Pulling the stick back will cause the robot to move backward. Moving the stick to the right or left will cause the robot to turn to the right or left respectively. Movement is fully proportional so any variation or combination of movement is possible. The horizontal and vertical trim tabs to the left and below the joystick are for centering and should be adjusted periodically.

  • How to Configure Radios for Use with Repeaters
    Concept of How to Configure Your Handheld and Mobile Radio for Use on a Repeater System VA6RPL Peter LaGrandeur Calgary Amateur Radio Association 2015 Learning Conference Limitations of “Standalone” Radios such as Handhelds and Vehicle Mounted Mobiles. Short Range of Coverage Signal easily blocked by major obstacles such as mountains, valleys, urban infrastructure What is a “Repeater” Radio? A repeater is basically a two way radio that receives a signal on one frequency, and simultaneously retransmits it on another frequency. It can retransmit with much greater power than received, and can send over a much wider area. A good example is where users are scattered in various areas separated by mountains; if a repeater is situated on top of a central mountain, it can gather signals from surrounding valleys, and rebroadcast them to all surrounding valleys. Handy! From there, repeater stations can be “linked” together to connect a series of repeater radios, each in a different area. With this, every time a user transmits on his mobile or handheld, his call will be heard simultaneously over all the repeater transmitters. And, yes! Repeater stations can now be connected via the internet. This internet linking is called IRLP – Internet Relay Linking Project. For example, a repeater in Calgary can link, via the internet, with an IRLP repeater anywhere in the world. You can carry on a two way radio conversation with someone in a faraway land with the assistance of the internet. Locating of Repeater Stations The higher the better. Yes, there are even satellite repeaters for amateur radio. In places that afford the best coverage in as many directions as possible.

  • The FCC Filing
    Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC.

The system is composed of a drone charging station with multiple power transmitters and a receiver to charge the battery of a drone. A resonance inductive coupling-based wireless power transmission technique is used. With limits of wireless power transmission in inductive coupling, it is necessary that the coupling between a transmitter and receiver be strong for efficient power transmission; however, for a drone, it is normally hard to land it properly on a charging station or a charging device to get maximum coupling for efficient wireless power transmission. Normally, some physical sensors such as ultrasonic sensors and infrared sensors are used to align the transmitter and receiver for proper coupling and wireless power transmission; however, in this system, a novel method based on the hill climbing algorithm is proposed to control the coupling between the transmitter and a receiver without using any physical sensor. The feasibility of the proposed algorithm was checked using MATLAB.

  • What Can You Do with a Dip Meter? Quite a Bit! the Dipper Is One Piece of Test Equipment That Can Replace a Whole Shelf of Expensive Gear—If You Know How to Use It
    By Mark Bradley, K6TAF What Can You Do with a Dip Meter? Quite a bit! The dipper is one piece of test equipment that can replace a whole shelf of expensive gear—if you know how to use it. s radio amateurs we are often interested in resonance. What is the resonant frequency of that antenna I just Aput up? Is that trap resonant at the frequency I think it is? That crystal, the one with the strange markings, is it good for anything? Do I have an inductor in the junk box that will work in the next project? How do I find the value of those mica capacitors with the cryptic markings? Is that chunk of coax really a ¼ wavelength at the frequency I hope it is? These are all questions that can be answered by using a dip meter or “dipper” to measure resonance—just one of the instrument’s many uses. A dipper makes a very sensitive absorp- tion wave meter for measuring a signal frequency. Since a dipper is an oscillator, I have used it as a signal source to troubleshoot receivers, as well. Figure 1—Several common types of dip meters are shown with All this versatility comes at a price; a dip meter is not a their plug-in coils that determine the oscillator’s frequency. precision instrument. There are techniques to reduce errors to acceptable levels, which will be discussed later. In case you haven’t guessed by now I am a big fan of dip meters—mine its use as an absorption wave meter.

Digital Mobile Radio (DMR) was developed by the European Telecommunications Standards Institute (ETSI) and is used worldwide by professional mobile radio users. DMR is divided into three tiers. ◦ Tier I ◦ Tier II ◦ Tier III Tier I Tier I is a single channel specification originally for the European unlicensed dPMR446 service. It is a single channel FDMA 6.25 kHz bandwidth; the standard supports peer-to-peer (mode 1), repeater (mode 2) and linked repeater (mode 3) configurations. The use of the Tier I standard has been expanded into radios for use in other than the unlicensed dPMR446 service. Tier II (The Standard for Amateur Networks) Tier II is 2-slot TDMA 12.5 kHz peer-to- peer and repeater mode specification, resulting in a spectrum efficiency of 6.25 kHz per channel.
