KLog 0.9.1.1: Quick bugfix

As other times… Murphy arrives and just after the release I have found a small bug.

So, as I had my computer still on, I fixed it and released again.

(Download KLog)

The bug was only afecting satellite QSO and it is now fixed.

KLog 0.9.1: Managing several logs

Managing several logs is the main new feature of this release of KLog.

(Download KLog)

KLog can manage several logs at once an the user may add/edit/delete different logs. I.e one per contest or DX expeditions, years, … different calls, …

I have also made the ADIF compatible with LOTW when including satellite QSO and a minor improvement on DX-Marathon support.

This is the Changelog this time:

April-2015 – 0.9.1
– Bugfix: Fixed DataBase::getBandIdFromFreq it was not ansswering properly.
– Now checks if band & frequency are coherent before adding a QSO. Band wins.
– All Satellite QSO include the PROP_MODE ADIF tag to make it compatible with LOTW.
– Improved the DXMarathon code.
– GUI: Added basic Satellite support.
– GUI: It is possible to mark a QSL sent via bureau/direct & DX QSL as requested with one action from Search box.
– GUI: KLog request a valid QRZ and at least one first logtype to start using it.
– KLog supports the management of several logs, being possible to edit, remove and select the one to use.

Today, KLog is translated into Spanish & English. If you can help me translating into another language, please contact me.

 

Enjoy KLog, the Linux, OSX & Windows free hamradio logging software.

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.

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.

AO-73 satelllite Telemetry

Today I have used the latest AO-73 satellite pass to try to receive the telemetry is always broadcasting.

The equipment used today was the following:Satellite antennas

It is quite easy to receive the sounds from the space with this equipment…. I will try to receive it with less equipment and maybe a vertical antenna during next passes :-)

The result has been quite good as I have been able to read the data from the satellite and during the pass.
Data has been updated 2-5 times, being able, for example, to see how the temperature of the power amplifier was raising from 14 to close to 17 degrees, maybe because the transverter being used by several hamradio operators that were making many QSO at the same time.

The telemetry was received around 145.935 (+- doppler effect) BPSK.

This is how the Funcube-1 dashboard looks like with my received data:

AO-73 telemetry

It’s been a really interesting experiment!

SSTV from the ISS

Last friday I read a new post in the ARRL web site explaining that the ISS had scheduled some SSTV transmissions during the weekend.

Not having practice SSTV for several years and not even having my satellite antennas installed may have been a problem although it is known that it is quite easy to receive the ISS when is flying above us…

So no time for plans, I would use my installed equipment for this:Gpredict screenshot

(The GPredict screenshot is not from last weekend but comming from a previous post)

With this setup was not difficult to plan the reception of the images for the following passes of the ISS over Madrid. You just need to tune your receiver in 145.900MHz FM.

This is what I got:

201502011953 201501312049 201501312043

The lines you can see in the images are usually interferences, mainly in the third one, caused by voices of a woman, speaking, probably in Russian…
