El establecimiento satisfactorio de enlaces HF entre dos o más estaciones depende de varios factores: la destreza de los operadores, los equipos y antenas utilizados y la selección de una frecuencia o conjunto de frecuencias adecuado. Para que un enlace de HF entre dos puntos tenga posibilidades de establecerse, ha de respetarse la regla fundamental de trabajar en una frecuencia que esté por debajo de la máxima frecuencia utilizable (MUF) existente para la geometría del enlace entre esos dos puntos concretos. Ha de tenerse en cuenta que la MUF será diferente para cualquier otra pareja de puntos distintos, hecho a tener en cuenta en la planificación de frecuencias para mallas de HF en las que participen más de dos estaciones.
New Amateur Radio Product to be Exhibited Prior to Worldwide LaunchJVC KENWOOD Corporation is proud to announce that the prototype of a state-of-the-art Amateur transceiver scheduled for worldwide launch under the KENWOOD brand in the winter of 2012 will be unveiled as a reference exhibit at Dayton Hamvention 2012 to be held in Dayton, Ohio, USA (May 18-20). It will also appear at events in Germany and Japan.
Reference exhibit model: TS-990 HF/50 MHz Transceiver
Featuring a dual TFT display and dual receiver, the TS-990 is a top-of-the-range flagship model in the KENWOOD Amateur radio line-up. Prior to the launch of the TS-990, a prototype will be displayed as a reference exhibit at Dayton Hamvention 2012 in Dayton, Ohio, USA (May 18-20), at HAM RADIO 2012 in Friedrichshafen, Germany (June 22-24), and at Ham Fair 2012 in Tokyo, Japan (August 25-26).

Endlich geht es los: Die kleinen und feinen Software-defined Radios (SDRs) bekommen langsam aber sicher auch einen Sendeteil. Der ZS-1 aus dem russischen St. Petersburg ist nicht nur der erste dieser Klasse, sondern er setzt gleich Maßstäbe, wie Nils Schiffhauer, DK8OK, herausfand.
Ahora las USB TV stick con chipset Realtek RTL2832 se pueden utilizar con programas como HDSDR y WRPlus
Hasta ahora, teniamos una amplia selección de opciones para la recepción SDR, desde la serie Softrock , pasando por el Dongle Funcube Pro hasta el USRP . Todos ellos varían en capacidad, por lo general más o menos de acuerdo a su precio, pero ahora aparece un nuevo chico en escena: El DVB-T sintonizador de TV digital.
Looking for some hardware to learn about SDR? This project may be just what you need to explore this hot topic!
This article describes the design and the theory of operation of an HF radio receiver operating in the 3.5 to 18 MHz range. The receiver architecture is based on software defined radio techniques and incorporates a Cypress PSoC CY8C3866 device that contains both analog and digital circuits, thus decreasing the receiver's component count. This part is far more than just a microcomputer; it also contains software configurable analog and digital peripherals on a single chip. Cypress calls the family a PSoC in reference to it being a programmable embedded system-on-chip. The newest series of parts, which Cypress calls the PSoC 3 family, contains a 67 MHz 8051 class microcomputer, an analog to digital converter fast enough and with enough resolution for an SDR receiver, and other valuable functions that are desirable in a receiver design.
SOS ... SOS ... Titanic!In 1910, the government required all ships to have a wireless telegraph. Yet by 1912, fewer than 400 ships were equipped with Marconi wireless. It was the Titanic disaster, just off the coast of St. John's, Newfoundland, which finally proved the value of wireless to the world. This article is about the Titanic´s fateful day and the two wireless operators, John Phillips and Harold Bride, who performed their duties with valor and honor.
