KLog 0.6.1 – released: Another bugfix release

Posted by on 2013/06/20 No comments

As I told you some months ago, I keep rewriting a new software… but my free time is close to zero 🙁 sometimes code some lines but my time in radio is mostly spent in the radio 🙂

However… yesterday I was DXing in 50Mhz and I noticed that the bearing was not correct and the coding-virus made me fix the bug ASAP.

So … here is the data of this new release:

DOWNLOAD:
Download KLog 0.6.1 from:

The Debian package has been already uploaded to the Debian servers.

This releases has the following Changelog:

June – 2013 – 0.6.1

  • Bug fixed: Locator was not properly calculated due to a sign difference management from KLog and CTY.DAT.
  • GUI updated: The cursor position management of the QRZ box has been improved to ease the operation.

As always, KLog is available in English, Spanish, Portuguese, Brazilian Portuguese, German, Serbian, Galician and Swedish.

Thanks for your help and I hope you find KLog useful.

Reparando el display de un Kenwood TM-255

Posted by on 2013/04/06 No comments

Hace algun tiempo compré un Kenwood TM-255 de segunda mano para mi estación de satélites.
Es un buen equipo y me permitiría completar mi estación para poder trabajar en full duplex y así acceder a los satélites con transpondedor lineal: FO-29, AO-7 y VO-52.

El único problema que tenía ese equipo era que la iluminación del display no funcionaba. Un problema menor, el equipo funcionaba perfectamente salvo ese tema.

Display apagado

Tras algo de investigación por Internet vi que el problema del display era más que habitual y decidí solucionar ese problema.

KLog 0.6.0 released… 10 years of KLog and some news…

Posted by on 2013/01/30 No comments

KLog is now 10 years old!! Wow time goes really fast! 🙂

Last release of KLog was one year ago… and this release is not adding many things… Bug fix as last one.
However… does it mean that KLog is dead?
Not it is not. 🙂

During this time I have been rewriting ALL KLog and now, the new software can be compiled for Windows and (probably) OSX (although I have still not tested OSX).
Of course… the new code will be released for Linux, as today !!
The idea behind this is making available the free software I am doing for more hams.

Lanzamiento del ARISSAT-1

Posted by on 2011/08/02 1 comment
SuitSat-1 tras su liberación

SuitSat-1 tras su liberación de la ISS

Hace ya unos años (en 2006) se lanzó SuitSat-1, un experimento en el que se introdujo un pequeño equipo de radioaficionado en un traje de astronauta viejo y se liberó en el espacio desde la Estación Espacial Internacional (ISS) (recordad el apunte en el que decía que la ISS es visible desde la Tierra).

Aquel experimento fue un éxito y mañana miercoles 3 de agosto de 2011 se procederá a la liberación del SuitSat-2, que ahora se llama ARISSAT-1 (y esta vez no va dentro de un traje real de astronauta sino en una mecanización más acorde con un satélite), también desde la ISS. La liberación se hará a las 14:00 GMT (a las 15:00 hora peninsular española) por lo que podremos seguirlo en directo a través de NASA TV.

El ARISSAT-1 es un satélite más complejo, pero con la misma filosofía: un “traje” de astronauta, relleno de equipos de radioaficionado y alguna otra cosa. Read more »

Apuntar las antenas…

Posted by on 2011/01/30 3 comments

Hace unos días instalé, para unas pruebas, una antena yagi de VHF y UHF en un mástil con un rotor pequeño que tengo para las salidas al campo en los concursos de VUHF con la idea de hacer algunas pruebas de comunicaciones vía satélite de radioaficionado.

Ayer pude trabajar una estación de Salamanca a través del SO-50 y hoy he trabajado una estación de Segovia y otra de Baleares a través del AO-51.

Gpredict screenshot

Además, he seguido un pase al HO-68, un satélite chino, pero no he escuchado nada… no se si estará apagado o en mantenimiento o simplemente no llegaba con la fuerza suficiente en este pase.

Los contactos de radioaficionado a través de satélite son una actividad divertida pues exige el control de varios parámetros de forma simultanea:

  • La orientación de la antena. El satélite hace un pase alrededor de la Tierra y tienes que apuntar la antena hacia el satélite e ir ajustando la orientación (tanto en acimut como en elevación) según va avanzando el pase.
  • La frecuencia de recepción. Debido al efecto doppler producido por el desplazamiento del satélite la frecuencia en la que se recibe al satélite varía a lo largo del pase, primero se encuentra más alta de la frecuencia “real” y según el satélite se aleja, la frecuencia va bajando y tienes que estar ajustándola continuamente en el dial si no quieres perder la señal.
  • Polaridad de la antena… aunque lo recomendable es poder variar la polaridad de la antena para ajustarse a la que utiliza el satélite, mi antena actual es de polaridad horizontal. Una polaridad circular a derechas (RHCP) es generalmente lo más frecuente.

Así que, además de tener una mano en el rotor y otra en el díal de la emisora, debes manejar el micrófono para hablar y apuntar bien a mano o bien con un ordenador los datos del comunicado (generalmente indicativo del corresponsal y locator).

Los pases son cortos, de 2 a 10 minutos ¡pero son 10 minutos de actividad frenética!

Hoy me he dado cuenta de que no tengo la antena bien orientada… he visto que la antena está unos cuantos grados desorientada por lo que las señales que estaba recibiendo eran bastante malas y a duras penas podía escuchar a mis corresponsales.

Utilizar un satélite de radioaficionado es el siguiente paso, tras ver la Estación Espacial Internacional ISS, desde la puerta de mi casa.

Tendré que subir al tejado, brújula en mano, a reorientar la antena. 🙂

Nota: El programa de seguimiento de satélites que hay en la imagen es GPredict. Un programa de software libre que corre en Linux, Windows y MACOS.

KLog 0.5.7 released

Posted by on 2010/11/12 No comments

It’s time for another KLog release.

KLog 0.5.7 is not a very big release… but it comes with some additions that may be nice for some of you. As I was announcing in my previous post about KLog.

I have added a very basic function capable to export all the needed QSO that has not been QSLed to a file… that can be imported to a label software to create the labels for the QSLs. I will continue working in the label generation feature of KLog for next releases.

The Changelog for this release reads as follows:

November-2010 0.5.7
– New feature: Added the Export needed QSL that allows to create an ADIF file with all the QSO with new ones and new bands still not confirmed that has not been QSLed.
The objective is to export it to a QSL or label printing software (until KLog implements that feature).
– Updated translations: SV by SM4ABE.
– GUI improved: Added sliders to be able to move panels.
– GUI improved: Changing the band combobox changes the TX Freq box and viceversa.
– Minor fix: The PROGRAMVERSION tag in log was not properly formated.

You can download KLog 0.5.7 from the mainsite.
You can also have more information in the main page of KLog or following the KLog’s tag in this blog.

KLog is free and open software and you can join the KLog’s team if you wish to help the development.
Please, send me all the bug reports and suggestions you have to improve KLog!

I hope you will like KLog.

KLog updates

Posted by on 2010/07/26 No comments

It’s been a long time since I published new information about KLog in this blog but KLog’s development has not been quiet.

Since the bug warning of KLog 0.5.3 I have released once each two months.

KLog 0.5.4 came during March as you can see in the announce of KLog 0.5.4.

It was mainly a bug-fixing release as you can see the the changelog:


March-2010 0.5.4
- Small fix to initialize a variable before using it.(realTimeLog in klog.cpp)
- Fixed a bug that caused KLog to crash of no cty.dat file was found (bug #016917)(TNX KA6MAL)

During April I released KLog 0.5.5 with a two interesting features (yes, the changelog shows three but for the user it would seem as just two):


April-2010 0.5.5
- New feature: If cty.dat file is not found, KLog offers to download from the web.
- New feature: New tool to update the update the cty.dat file from the web.
- New feature: QRZ font color changes to red if has been worked previously. (Proposed by KE7TDY)

I think it will improve the easy of use of KLog. Next phase would be to check if there is a new version of the cty.dat file and propose to download it.

And we get to July, when I released KLog 0.5.6, a minor release in terms of usability, not important KLog’s sources bugs solved, but definitely an important release as it has improved the way it manages how the compilation process manages the hamlib sources, and has ended with KLog in Fedora 🙂


From the Changelog:
July-2010 0.5.6
- Fixed the hamlib compilation scripts (CMakeLists.txt, FindHamlib.cmake). (TNX AB4BD).
- Fixed one bug that causes some architectures not to compile.
- Fixed some permisions and other warnings for Fedora packaging. (TNX N3LRX).

Now I am working in KLog 0.5.7 and I hope it will be ready for release soon. I am working in a new tool of KLog that will export the QSOs that are still needed and we still have not sent the QSL card so that log can be imported in a label printing software to print the labels and send ALL the QSL cards easily.
I will export an ADIF file and maybe a CSV file to be imported into GLabels.

The proper way to go would be to create a label printing feature but it is a longer process and I wanted to speed up my own QSL card process 🙂

While new release is ready: download KLog
