Todo lo demás / Wimo ha comprado EAntenna
« Último mensaje por EA1DDO en Agosto 29, 2018, 11:38:32 am »
Hola,

Pues parece que Wimo no para.
Recientemente Wimo ya había comprado Ultra-Beam, como comenté en este mismo foro, pues ahora también han comprado EAntenna.
Al igual que con Ultra-Beam, se van a llevar la fabrica a Alemania, y desde allí seguirán haciéndolas, de hecho, Rod EA7JX se va para allá con su familia.

Como resultado de eso, HamRadio.es creo que se va a traspasar.

WiMo acquires EAntenna

Herxheim, August 24., 2018

Germany’s largest provider of amateur radio products announces the acquisition of the spanish antenna manufacturer EAntenna.
EAntenna

WiMo Antennen und Elektronik GmbH (Herxheim) will take over sales, service, manufacturing and the trademark of the Spanish manufacturer of short-wave antennas, ‘EAntenna’ from Brenes (Spain). EAntenna has been manufacturing a broad range of HF and VHF / UHF antennas, masts and accessories since 2010. The antennas are used internationally by radio amateurs and commercial radio services for worldwide voice and data communications, and are offered by 20 distributors worldwide.

Volkmar Junge, Managing Director of WiMo: “WiMo has been the largest distributor of EAntenna for a very long time now. Our sales and service teams know the entire EAntenna product portfolio. As we already have our own production lines for a wide range of antennas, we see great leverage in the consolidation of the Spanish production into our manufacturing in Herxheim. This will enable us to provide our customers with the premium support they are used to getting from WiMo’s own product range.”

The former owner of EAntenna, Rodrigo Herrera, EA7JX, will move to Herxheim with his family. Both he and his wife Angeles, who also has extensive knowledge of the EAntenna product portfolio, will continue to work for WiMo after the takeover. Rodrigo Herrera: “We now have the chance to develop the EAntenna product portfolio and take it to a totally new level with a very strong partner. We are very happy and excited to be able to work for WiMo in Germany.”

Volkmar Junge: “The fact that key personnel of EAntenna will continue to work for us is going to ensure that there will be a smooth transition of the production and customer orders can continue to be delivered on-time. At this point, we have enough EAntenna products on stock and lead-times should be below three weeks. In addition we can now offer Spanish, Portuguese and Italian support for our entire product portfolio and we expect to improve our presence in these countries.”

Production will move from Spain to Herxheim in September 2018.

    WiMo Antennen und Elektronik GmbH is Germany’s largest provider of amateur radio equipment, antennas and accessories. With more than 40 employees, the company location in Herxheim (Rhineland-Palatinate, district Südliche Weinstraße) is home to a production facility for antennas, cables and accessories. In addition, WiMo offers amateur radio gear from most well-known manufacturers plus a wide range of accessories with more than 4500 products.
    EAntenna is an owner-managed company in Brenes (Andalucia, Spain). With 6 employees, Rodrigo Herrara has been building up a renowned brand for antennas for almost 10 years.

Electrónica, equipos, técnica, etc. / GI46B en TL922
« Último mensaje por EA3KP en Agosto 21, 2018, 05:39:28 pm »
Hola,

Debido a la falta de la 3-500Z en el mercado ,se instala unas GI46B,pero pensar que la impedancia de entrada no es la misma,y el bias tampoco,hay que reajustar los circuitos.
Otro problema y es lo mas importante es la ventilación,hay que dirigir el aire de abajo a arriba ,la turbina original solo sirve para extraer el aire caliente,algonos montar turbinas por debajo de las válvulas pero hay que canalizar el aire parta que sea eficiente.
Las GI salen mas baratas pero al final la QB4  sale mas rentable,menos complicaciones.
Saludos

Todo sobre Antenas / WIMO ha comprado Ultra-Beam
« Último mensaje por EA1DDO en Agosto 08, 2018, 12:46:46 pm »
Hola,

Ayer he visto que WIMO ha comprado el fabricante italiano de antenas dinámicas Ultra-Beam.

Según dicen en su página, han comprado la marca y los detalles de fabricación para llevarse a Alemania la fabricación, distribución y venta de las antenas.

En Italia queda una distribución independiente solamente para los clientes italianos; www.antennahub.it

Aunque no tiene nada que ver con el Yaesu, también tiene derecho a ser comentado ya que se presentó al mismo tiempo.
El Nuevo Kenwood TS-890S



Parece un TS-990S que le han sacado uno de los receptores, por lo que ha quedado más pequeño, algo similar el FT Dx-101D.
Lo que ocurre es que Kenwood aún no se ha puesto con el SDR, y este TS-890S sigue siendo analógico, como su hermano mayor TS-990S.

Para ser honestos, el aspecto de éste TS-890S es muy logrado. Ofrece seriedad y elegancia.

Hola,

Pues tras muchos años de retraso (comparando con Flex, HPSDR, Icom, etc), por fin Yaesu acaba de presentar en Dayton su primera radio SDR, el FT Dx-101D.



De momento se sabe muy poco de ella, incluso en Dayton solo se podía ver, no tocar, ya que estaba dentro de una protección transparente.

A todo lo que ahí dice, se puede añadir que la versión europea llevará la banda de 4m (70 MHz).

Otros datos;
Medidas 420×130×320mm
Peso 12kg
Fecha estima de venta: Octubre 2018

Hola Borja,

Ese es interesante también y tiene buen precio.
Hay otro similar, a mitad de precio, aunque no es tan estrecho:

Habrá que pensarlo.

Gracias
