Working FT-8 with WSJT-X and a smartphone

Posted by on 2018/09/18 No comments

Working FT-8 is usually really easy thanks to WSJT-X.

It doesn’t need to much actions from the operator… just double click and wait and all the QSO will be done more or less automatically.

This way of automatize the QSO may be sometimes a little bit boring as you don’t have to do many things but it also has some benefits.

I was looking for a way to practice some hamradio when I was not at home… I have tested several things but all of them required quite a lot of equipment and complex operations, a computer or whatever.

So, my target was to find a way to do something from my smartphone.

Remoterig has an android software that you can use, even for voice communications… it is not too bad but it is not the best to call a DX when you are on a public place like a supermarket, in an airport… anyway, digital communications came to my mind.

The first step is to make everything work locally:

Raspberry Pi with Raspbian and WSJT-X.

Once my radio is connected to the Raspberry Pi and it is possible to do QSOs, it is time to do it remotelly.

In the Raspberry Pi, install the realvnc-vnc-server package.

In my smartphone I installed also the VNC Viewer app.

Now I can connect my mobile to the VNC server in the Raspberry Pi.

To switch on and off the Raspberry Pi and the radio remotely I am using a RemoteRig WebSwitch and the Android app. It is a very basic app, not very fancy but it does what it is expected to do.

That’s all, just one additional comment to this configuration:

I don’t recommend to expose directly the VNC server in your home network to the Internet.

How to connect securely and configure a VPN to connect from the Internet to my home network so I can connect via VNC to my Raspberry Pi is out of the scope of this post 🙂

So, today I am able to do digital communications with my Smartphone, wherever I am, connecting via VPN to a Raspberry Pi at home.

It is great to feel the hamradio is situations that it would not be possible!

The following is a screenshot of my smartphone:

Enjoy!

EME: Raspberry Pi 3 + Spyserver + wifi

Posted by on 2018/03/08 No comments

Hace unas semanas que he decidido empezar una cosa nueva que no he probado aun: EME / Rebote Lunar.

Básicamente consiste en apuntar tus antenas a la Luna, transmitir y que tus señales reboten en la Luna para alguien escuche esos rebotes desde la Tierra.

Se usa la Luna como pantalla para reflejar esas señales y así conseguir una comunicación entre dos estaciones terrestres.

El tema ni siquiera suena sencillo al contarlo así de rápido pero nadie negará que sea un reto!

Ahorraré detalles técnicos, la web está lleno de ellos y merece la pena leer mucho antes de lanzarse a la piscina pero… en algún momento hay que lanzarse.

No tengo el equipo más apropiado pero sí un par de ideas para ver hasta donde puedo llegar… luego ya iré consiguiendo el equipo según haga falta.

La primera fase de este acercamiento a la Luna consiste en recibir señales con el equipo que tengo:

Con la idea de minimizar pérdidas he pensado conectar la Raspberry Pi directamente a la antena, con no mas de 10cm de cable.

Para ello he montado una Raspberry Pi 3, con Spyserver y una conexión wifi.

Eso me permitirá usar el SDR# desde el cuarto de radio, con el WSJT-X y reducir al máximo las pérdidas en el coaxial.

Instalar el software es trivial siguiendo este tutorial de Spyserver en Raspberry Pi y en un rato está todo funcionando.

Siguiente paso: Conectar la antena y apuntar a la Luna. Habrá que buscar el día propicio.

Es muy posible que no consiga escuchar nada, así que habrá que ir preparando un preamplificador… pero eso más adelante, de momento empezaré con este equipo mínimo.

I have just released KLog 0.9.2.7.

Now it is released… but it does not mean that it has no bugs… it is just that I have not found them yet! 🙂

KLog 0.9.2.5 Another bugfix release

Posted by on 2016/11/02 No comments

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

Posted by on 2016/08/18 No comments

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!

KLog 0.9.2.1: Quick bugfix

Posted by on 2015/09/15 No comments

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:-)
