Recuperando un Microham MicroKeyer II

Hace unos dias, actualizando el firmware de mi MicroKeyer II tuve un problema y el proceso se quedó a medias, por lo que el dispositivo acabó convertido en poco más que un ladrillo, que no arrancaba ni era posible detectar desde el ordenador.

El uRouter no lo detectaba, y el icono de detección del microkeyer estaba en amarillo.

Lo que añado a continuación es el procedimiento que la gente de MicroHam me facilitó para intentar recuperar mi dispositivo y que funcionó a la primera:

Apagar el MicroKeyer II.
Conectarlo a un sistema MS Windows.
Arrancar uRouter.
Lanzar la actualización de firmware.
No más tarde de un segundo, encender el MicroKeyer II.

El dispositivo debería leer el firmware del ordenador y cargarlo correctamente.

Si el procedimiento fallara, probar de nuevo, tratando de acertar con el momento de encender el MicroKeyer.

En mi caso, el procedimiento funcionó a la primera y recuperé el MicroKeyer II en menos de 2 minutos.

Satélites: Trabajando el AO-7

(Este apunte estaba como borrador desde hace tiempo)

Acabo de realizar dos comunicados y medio[1] a través del AO-7, un satélite más viejo que yo, que fue lanzado en 1974 y sigue permitiendo buenos comunicados a los radioaficionados cuando está iluminado.

Como acabo de decir, el AO-7 u OSCAR 7 solo funciona cuando la luz del Sol ilumina sus paneles solares porque cuando está en zona de oscuridad (cuando la Tierra se interpone entre el Sol y el satélite) se queda sin energía y no es posible utilizarlo. Las baterías dejaron de estar operativas en 1981!

El AO-7 funciona en modo A, por lo que la subida (uplink) está centrada en 145.900MHz y la bajada (downlink) está en 29.450MHz… Esto quiere decir que, con un equipo que pueda recibir en 29MHz, en USB es posible escuchar el satélite.

Así que ¿Qué se necesita para trabajar el AO-7?

Emisoras:

  • Un transmisor de VHF con banda lateral (USB) (en mis pruebas con no más de 20W suele ser suficiente si el satélite no está cerca del horizonte). Yo uso un Kenwood TM-255.
  • Un receptor de HF (uno de 10m es suficiente) con banda lateral. Utilizo un Yaesu FT-950

Antenas:

Rotor: Hay que apuntar las antenas hacia el satélite según se va moviendo. La de HF evidentemente no se mueve pero la de VHF si no la apuntas bien al satélite no podrás excitarlo. Yo uso un Yaesu G-5500

Programa de seguimiento de satélites: Es necesario saber cuando hay un pase del satélite… de nava sirve tenerlo todo listo si el satélite está al otro lado del mundo. Yo uso GPredict y mantengo los “keplerianos” actualizados.

Un poco de práctica… Si te interesa este tema, echale un vistazo al apunte que hice hace ya algún tiempo titulado “Apuntar las antenas…


[1] El medio contacto ha sido con una estación francesa con la que no he podido terminar el comunicado al no escuchar el QTH Locator. Los otros dos QSO han sido con una estación española y otra alemana.

Interferencia en 21MHz

Dando una vuelta por la banda de 15m, 21MHz me he encontrado una señal desconocida. Concretamente 21.310MHz.

Una interferencia continúa, a base de pulsos y con una señal MUY fuerte que impedía el uso de la banda en frecuencias próximas.

Habrá que investigar qué puede ser.

CQ WW RTTY 2017

Hace unos días tenia lugar el CQ WW RTTY 2017.

Casualmente en un rato de radio que tuve, me llamó la atención el espectro en 14MHz donde se ve claramente la actividad RTTY que tenia el segmento de comunicaciones digitales completamente lleno.

Aquí dejo una captura hecha con mi IC-7300.

KLog 0.9.2.5 Another bugfix release

Yesterday, after checking some new QSL cards I had received I found a bug that causes the exported ADIF file not to show the right band and mode.

I quickly posted a Tweet about the bug so the users were aware… Luckily the bug was easy to fix (in a quick and dirty way, honestly) and here comes the 0.9.2.5 release that brings no new feature but the bug fix.

KLog 0.9.2.4 RC1

I have just uploaded the release candidate (RC1)of 0.9.2.4.

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!
