KLog RC1

I have just uploaded the release candidate (RC1)of

As any other Release Candidate (RC), this is a RC version so no final.

I am releasing it for you to test, if you want to do some testing and report the bugs.

I will not add more functionalities in this version and I will release the final version in a couple of days, if nobody reports a serious bug.

You can find the packages here:

Please BACKUP ALL your data before upgrading.

Although I have done some tests on my computers, it may happen that this version (as any other) brings a bug… so please test.

My recommendation is that you backup the logbook.dat and the klogrc files.

Export also your log to an ADIF file before you update any KLog version.

Thanks for testing!

KLog now in Japanese and with an icon

I am happy to announce the release.
Download KLog from the Download Page.

KLog – Translations are working

This minor release of KLog is bringing some major-release items althought it was originally though as a minor / bugfix release.

(Download KLog)

One important point of this KLog version is that translations seems to be properly working now and we are bringing one additional language thanks to the great help of EA3NM who translated into Catalan. (Thank you Luis!).

KLog is now able to import Aether ADIF logs…

I will not use so much words explaining this version… as you can look the Changelog file:

KLog Quick bugfix

I have decided to implement a test-plan to do some specific tests before deploying any version.

I always do some tests before I deploy a new version of KLog but not on a sistematic approach, not always the same tests and it may happen (as this time) that I forget to test important functions of KLog.

Because of that, KLog 0.9.2 had an important bug that it is already fixed. KLog was not peoperly saving the band & mode information of new QSOs.

Please update KLog as soon as possible and sorry for the inconvenience O:-)

Otro satélite meteorológico: Meteor M2

Hoy he conseguido decodificar por primera vez una fografía del Meteor M2, otro satélite meteorológico, METEOR M2 2015esta vez ruso, a diferencia de los NOAA americanos.

El Meteor M2 fue lanzado en julio de 2014 así que es mucho más moderno que los NOAA que he recibido algunas veces y eso se nota en la definición de las fotografías que se pueden recibir de estos satélites.

El procedimiento de recepción de imágenes de este satélite no es tan directo y sencillo como los NOAA de APT, pero tampoco es especialmente complejo.

Teneis el tutorial que yo he usado aqui: tutorial de recepción METEOR-M2.

Esta ha sido la primera fotografía que he recibido y si pulsais en ella, podreis ver el detalle que ofrece. La foto está capturada en la mañana del día 2015-04-12.

Es interesante ver la nieve sobre los Alpes o los Pirineos.

El equipo utilizado es el siguiente:

  • X-Quad antena VHF.
  • SDR RTL comprado en eBay.
  • El software especificado en el tutorial del que hablaba antes.
  • Ordenador con MS-Windows.

APT = Automatic Picture Transmission (Satélites meteorológicos)

Esta vez APT no tiene nada que ver con seguridad informática (APT = Advanced Persistent Threat) sino de nuevo, con radioafición y satélites.

Aprovechando un día de vacaciones me he entretenido en cambiarle el conector a mi SDR RTL y ponerle un pigtail con un SMA, de forma que pudiera, con un adaptador, conectarle a través de un PL 259 a mis antenas de satélite.

El objetivo, poder decodificar las imágenes del satélite METEOR M2, un satélite meteorológico ruso con el que nunca he jugado hasta ahora y que fue lanzado al espacio en junio de 2014.

El cambio de conector muy sencillo, un chorro de aire caliente con el soldador de unos segundos y 2-3 minutos más para soldar el pigtail y el receptor está actualizado.

La recepción del satélite requiere que este pase por encima de nosotros para poderlo escuchar… así que con GPredict, como he mostrado otras veces, se pueden calcular los pases.

Para probar que todo iba bien, antes de apuntar al METEOR M2, he querido probar con uno de los satélites meteorológicos clásicos, con los que ya tenía experiencia, para asegurarme de que todo iba bien y que por suerte, tenía un pase muy pronto.

Gracias a WXtoImg he podido decodificar la siguiente imagen:

Es una imagen con una calidad media, sobretodo en la parte sur, pero hay que tener en cuenta que la he grabado directamente a través del micro del ordenador… mientras con el GQrx recibía las señales del satélite y las reproducía a través del altavoz… así que entre el ruido ambiental y las propias condiciones de recepción de una imagen de este tipo, este ha sido el resultado. He reducido el tamaño de la foto para ahorrar espacio, así que la original tiene algo más de definición.

20150306 NOAA-15 wxtoimg


Como me gusta indicar el equipo que uso cuando publico una cosa de estas, paso a detallar el equipo utilizado:

  • X-Quad VHF antenna (the big one in the photo) 🙂
  • SDR RTL comprado en eBay.
  • GQrx para la recepción de las señales.
  • WXtoImg para la decodificación de las imágenes.
  • Ordenador MacBook con OSX.

Siguiente paso, recibir las imágenes del METEOR M2.

Montando un Kit de Software Defined Radio

[Este apunte lo tenía escrito, como borrador desde hace unos meses]

Hace tiempo que perseguía la web de KB9YIG con la esperanza de comprar un Kit de SDR. Salen de vez en cuando 10-30 unidades y a las pocas horas, días como mucho, se agotan así que hay que estar atento.

Un anuncio en el foro de URE me dió la alerta y conseguí un “SoftRock RXTX Ensemble Transceiver Kit”: Un transceptor de 1W, que puedes montar para que funcione en un conjunto de bandas de HF: 160m, 80m/40m, 40m/30m/20m, 30m/20m/17m or 15m/12m/10m.

Así que tras unos días de espera (unos 10-15) me llegaron dos sobres con los componentes, la placa de circuito impreso, los conectores, …

Hay unas instrucciones de montaje en la web de WB5RVZ que son bastante sencillas de seguir.

El kit se monta por bloques que se van probando antes de pasar al siguiente.

Ensemble RXTX

La mayoría de los componentes son componentes discretos, convencionales aunque también hay algunos componentes de montaje superficial: condensadores y circuitos integrados.

Para los SMD necesitas un poco más de experiencia con el soldador ya que algunos son especialmente pequeños; hay que tener una buena punta en el soldador y buen pulso!!

Además, hay que cablear bobinas y transformadores así que hay un poco de todo.

En resumen, un buen kit, de momento el montaje es entretenido y va funcionando aunque aun no he llegado ni a la mitad!

Un puzzle recomendado para los aficionados a la electrónica.
