Addition to the portable kit..

Last spring I completed my portable kit for digimodes on HF to be used during the summer of 2016. Unfortunately I didn’t got to use the kit as much as I wanted due to family activities and work, so the kit was mostly just in standby. However, I´ve promised myself to be more active this spring and summer. This because both me and the rest of the family need to get out more. That´s why I’m about to try to plan a number of outdoor activities together with the family this spring and summer and work some QSO:s with the portable kit. 🙂

Regarding the portable kit, the small Intel Atom computer I´m using for the kit is pretty slow when using it with WSJT-X 1.7. Also, the battery is not good to last more than 10 min and one hour the most on the battery bank for the radio. This made me thinking about a replacement of some kind that´s small, light and ultra portable. By accident my partner stumbled up tablet which seemed interesting.

The tablet was an Trekstor Wintron 7.0 tablet which seem to use Windows 10 Home instead of Android. This was particularly interesting as the chance that it would be able to recognize both the signalink and the CAT-adapter was quite higher than an android or Windows 10 Mobile tablet. The specs also seemed to match what I was looking for, 1.8GHz CPU and 1GB of RAM (WSJT-X requires 1.5GHz CPU as a recommendation).  The cost was only 60 Euros why I gave it a try! I ordered one online and a few days later I got the package.

dsc_1864The same night I got the package I started to experiment with the tablet. As the OS of the tablet was Windows 10 and the limited disc space of 16GB, I was afraid that it might not be able to support any of my external USB-devices. I was wrong! I also expected the Windows version to be a “sneak” version adapted for tablet use, but it turns out it really was a full Win 10 Home that was installed. It was able to handle the signalink directly to the USB port via the USB-adapter cable that came with the tablet. Since I wanted to connect more devices to the USB-port I then tried to connect a USB-hub with the signalink, CAT-adapter and a wireless mouse. This didn’t work good at first but after som tweaking in the device manager (energy saving properties) I was able to get it to work!

I then installed WSJT-X 1.7 and tried to run it monitoring the 40m band that normally has a lot of traffic during the evenings. My intention was to try to put some stress on the tablet as the decoding is the most critical point in running the JT modes. This regarding both time and processing power. It actually decode OK and the tablet could handle the extra CPU-load during the multipass decoding without any problems at all!

No need to say I was very pleased this had worked! Now it was time to give it a trial run before officially giving it a place in the portable kit! 🙂

I left it running, from fully charged, and managed to get about two hours of running time before the internal battery was depleted. An OK time! 🙂 I also made a couple of QSO:s on JT65 and JT9 and I’m more than satisfied with the solution! I also discovered that my protection case with integrated bluetooth keyboard for one of my older tablets also worked with the new one. This made the setup even more complete. 🙂

So now I have an updated portable kit, ready for this spring and summer adventures! 😀

Presentationer och föredrag, WSJT-X och digitala trafiksätt..

Från och med 2017 har jag beslutat mig för att öppet erbjuda olika föreläsningar, presentationer eller kurser gällande digitala trafiksätt. Målgruppen är främst amatörradioföreningar eller klubbar och sker helt ideellt utan kostnad.

Som start erbjuder jag förevisningar, kurser eller presentationer av WSJT-X för JT65 och JT9. Se sidan “Föredrag” för mer information. 🙂

Release of WSJT-X V1.7.0

wsjtx170Just a few minutes ago the new release of WSJT-X, V1.7.0, was released by K1JT, Joe on the WSJT-homepage. The new version contains a lot of new functions an modes but the most useful update for us using the software on the HF-bands is the new Franke-Taylor decoder. This decoder replaces the Koetter-Vardy decoder used in previous WSJT-X versions. The KVASD is no longer necessary to install. In addition to this there is now multi-pass decoding which is very helpful in the crowded JT65-frequencies. The function uses two decoding passes instead of one, increasing the possibility to decode overlapping transmissions or weaker stations buried in a crowded passband.

Download the installation package for windows now from the WSJT-X website or click here to start the download.

Installation packages for Mac and Linux is also available on the WSJT-X website.

The Swedish translation of the user guide is not yet ready for release but will be finished in the first quarter of 2017.
Have fun! 😀

Svensk manual, WSJT-X

Under en längre tid har jag haft som projekt att översätta den engelska manualen till WSJT-X V1.6.0 för att underlätta för dem som vill ha en handledning av programmet på svenska. Översättningen blev idag färdigställd och har nu även publicerats på WSJT-X officiella hemsida.

För den som vill ladda ner manualen direkt finns här en länk där du kommer direkt till manualen:

text_to_speech_app_icon wsjtx-main-1.6.0.se.html

Vill du spara manualen på din dator, högerklicka då på länken och välj “spara länk som”.

Manualen är mer eller mindre en direkt översättning med kompletteringar i vissa avsnitt. Detta för att förtydliga vissa funktioner och möjliga inställningar.

Jag mottar gärna kommentarer om förbättringar som jag kan ta med mig in i arbetet med manualen för den kommande V1.7.0. Ni finner kontaktinformation här på min blogg.

Translations and summer plans..

It seems like there’s some time between the updates in the blog right now and I do have my reasons for it. A hectic work situation with a number of new projects starting and an ability not to leave the thoughts about the project situations when you get home have rendered me some what exhausted. However I’ve done some progress with my latest undertaking, the translation of the WSJT-X user manual into Swedish. svmanJust this morning I’ve completed the basic translation work and I now have to proof read the entire manual to check for consistency and spelling errors. After this, then additional content for WSJT-X V 1.7.0 has to be inserted.

The manual however is more or less a complete translation for the V 1.6.0 but as it has elements of the coming version in the texts it may be some what confusing to read in certain sections. There are also elements in the translated material that seems hard to change and are probably related either to the ASCIIdoc markup language or in the maner that the documentation is built. For example I can’t find out were to change the text “Table of Contents” in the left margin into Swedish as this is the only text that can’t be changed in the entire document, unless you change it in the compiled html-file. 🙂

Well, I guess I just ned to do some more digging to solve it I guess. 🙂

Thank’s to some work related circumstances I might get the chance to do some portable work on the Swedish West coast this summer. Even though it might be more work than play, I will try to find some time to make som QSO:s on digital and voice with my potable kit. The QTH is in the archipelago outside Gothenburg and I will probably be there for at least two weeks. Lets hope for the best! 🙂

New year, new projects..

I´ve just realized that it´s been a couple of months since I updated the blog and it almost seems a bit empty when there are no updates made to it. Honestly I´ve not really had the time or the inspiration for it the last months as my work and family life have been taking up the most of the time. Even the HAM-radio activities have been on the low side. Since it´s a new year now (2016 already!!) I´m looking in to what kind of new projects I might want to take on this year.

As you may already know I´m a big fan of the JT9/65 modes on HF and my activities are, except for the SJ7SOP activity, almost only digimode in HAM radio. This interest in JT made me sign up to the WSJT development e-mail reflector to get more insight in the development of the WSJT-X software. Also, I got the opportunity to try a number of development versions of the software through the WSJT-X user group on Facebook. Thanks to the helpful and kind work of Udo (DO1IP) who made the devel-versions available for testing in the limited user group, I was able to follow the development of the WSJT-X software and also witness the amazing progress that have been made with the JT65 decoder.

text_to_speech_app_iconI decided to give something back to the WSJT project and since my skills in programming is quite limited I´ve instead looked at the possibility to make a translation of the WSJT-X manual in to Swedish. The initiative seemed to be appreciated among the developers why I´ve started to learning the Asciidoc markup language and how to build the user manual. I´m quite excited about this undertaking which will not only put my translation skills to the test, but also gives me an opportunity to learn a new way of documenting.

A new release candidate is not far away for the WSJT-X software and the translation work will probably start when It´s released. 🙂

Another interesting thing that just recently started up here in Sweden is the Svenska Sjöar or Swedish Lakes Competition, SMSS, (homepage only in Swedish) which is a competition involving making QSO:s from as many Swedish lakes as possible. This is a good way to activate HAMs, showing the fun of portable operation, running QRP and of coarse enjoying the beautiful Swedish nature. Some of the club members in my local club, SK7JC, has decided to join the competition and is about to arrange a club meeting to exchange experiences with QRP and portable operation. I will certainly also be a part of it, however I would like the temperature to be at least on the + side before I make a trip outside. 😀

Meanwhile, waiting for the mercury to crawl upp, I´ll make some plans for spring activation of the SMSS competition. 🙂

New dev release for WSJT-X..

I discovered today on a JT65 facebook group that there is a new development release of WSJT-X available. This version, V1.5.0, is told to have some improvements  regarding decoding and computer optimization why it can be worth trying.

I’ve installed it on my own station computer along with the new release of JTAlert 2.6.0.

Also there is a new function regarding the colors shown in the Band Activity and Rx Frequency window which allows you to change the colors of the received messages. The pink one really added some color to the software! 🙂
