DESCRIPTORS *Communication (Thought Transfer); Educational Innovation; *Educational Radio; Educational' Technology; Elementary Secondary Education; Interdisciplinary Approach; Language Arts; Self Esteem; *Student Motivation; ''Teaching Methods; *Vocational Education IDENTIFIERS *Ham Radio ABSTRACT Amateur radio is a technology and activity that offers great potential when integrated into academic or vocational curricula. Programs with electrical, electronics, and electromechanical content can benefit from the use of amateur radio, and can also enhance language and communications skills. The biggest value of amateur radio may lie in its ability to enhance a student's motivation and self-esteem. In addition to its specific vocational and technical applications, amateur radio can assist in teaching basic skills and in reducing the isolation of students and teachers as it promotes interdisciplinary education and cultural awareness. Amateur radio is distinctly different from citizens band, as it is a noncommercial service. Ham operators do not need an electronics background, although technical knowledge and skills are helpful. Several examples of the educational use of amateur radio illustrate its potential for academic and vocational education.
A Simultaneous Radiotelephone and Visual Range Beacon for the Airways

RP341 A SIMULTANEOUS RADIOTELEPHONE AND VISUAL RANGE BEACON FOR THE AIRWAYS By F. G. Kear and G. H. Wintermute ABSTRACT Increased use of the airway radio services by transport operators has resulted in a demand for continuous range-beacon service. At the same time the weather broadcast information has increased in importance and the interruptions to the beacon service have become more frequent. To eliminate difficulties arising from this conflict a transmitting system has been developed which provides simul- taneous transmission of visual range-beacon and radiotelephone signals. This system is designed to employ existing equipment so far as possible. By combining two transmitting sets into one the cost of buildings and antenna equipment is reduced. Continuous check on the operation of both systems can be obtained with less personnel than required at present. The transmitting set consists of a 2-kw. radiotelephone transmitter operating into a nondirective antenna system and an additional set of amplifier branches supplying power through a goniometer into two loop antennas. The two antenna systems are symmetrically disposed with respect to each other, and coupling effects are balanced out to prevent distortion of the space pattern. The phase of the currents in the different antenna systems is controlled by a phase shift unit and means for checking the adjustment of this phase relationship continuously is provided. The equipment on the airplane to receive this service is changed only by the addition of a small filter unit which keeps the low-frequency reed voltages from reaching the head telephones and the voice frequencies from the reed indicator.

Part 13 Restricted Radiotelephone (Including Commercial Radio Operator)

Part 13 Restricted Radiotelephone (Including Commercial Radio Operator) RESTRICTED RADIOTELEPHONE OPERATOR PERMIT WHO NEEDS AN RP? At least one person holding an RP is required aboard stations in the maritime and aviation services when: making international flights, voyages, or communications; 2) using frequencies under 30 MHz; 3) using a satellite ship earth station, or 4) operating a vessel subject to the Bridge to Bridge Act (including domestic operation). WHO DOESN’T NEED AN RP? For mobile stations: 1) On board a voluntarily equipped ship using only VHF frequencies on domestic voyages OR using a radar, EPIRB, survival craft, or on-board station; 2) on board an aircraft using only VHF frequencies on domestic voyages OR using radar, radio altimeter, transponder, or other automated radionavigation transmitter; or 3) at a domestically operated marine utility station. For fixed stations: 1) at shore radar, shore radiolocation, maritime support, or shore radionavigation stations; 2) at a coast station or aeronautical ground station using only VHF frequencies; or 3) at an aeronautical enroute station which automatically transmits digital communications to aircraft. You no longer need an RP to operate a Broadcast station (e.g., AM, FM, TV). This requirement was eliminated on 12/1/95 (Report and Order, MM Docket No. 94-130 released 10/23/95).

K. Embabi Duncan M. H. Walker (Member) (Member) _________________________ Chanan Singh (Head of Department) August 1999 Major Subject: Electrical Engineering iii ABSTRACT A Multi-Band Phase-Locked Loop Frequency Synthesizer. (August 1999) Samuel Michael Palermo, B.S., Texas A&M University Chair of Advisory Committee: Dr. José Pineda de Gyvez A phase-locked loop (PLL) frequency synthesizer suitable for multi-band transceivers is proposed. The multi-band PLL frequency synthesizer uses a switched tuning voltage- controlled oscillator (VCO) that covers a frequency range of 111 to 297MHz with a low average conversion gain of 41.71MHz/V. A key design feature of the multi-band PLL frequency synthesizer is that the VCO tuning switches are controlled only by the normal loop dynamics. No external control is needed for the synthesizer to switch to different bands of operation. The multi-band PLL frequency synthesizer is implemented in a standard 1.2µm CMOS technology using a 2.7V supply. The frequency synthesizer has a measured frequency range of 111 to 290MHz with phase noise up to –96dBc/Hz at a 50kHz carrier offset.

The heads of the dog-bone face In this paper, we present a detailed description of a two electrodes called the gate, over small gaps (g) of MEMS frequency synthesizer product, including the 200nm. The resonator is actuated electrostatically by a principle, processing, system architecture, and reliability combination of a DC voltage (VDC) and an AC voltage and characterization results. The synthesizer is based on a (vin) applied on the gate (Figure 1, right), which drives the MEMS piezoresistive dog-bone shaped resonator, having resonator into the extensional symmetrical resonance a resonant frequency of 56MHz, and a Q-factor of mode shape. To sense the vibration, a DC bias current >40,000. Using a specific temperature compensation (Id) is sent though the beams via the anchors, which are algorithm, the output frequency can be kept stable within also called the source and drain terminals. Thanks to the ±20ppm over an operating temperature from -20°C to piezoresistance effect, resistance of the beams is +85°C. Jitter over a bandwidth from 12kHz to 20MHz is modulated by their strain, which results in an AC signal typically 2.96ps.
