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! 😀

Weekend Hamradio..

Sometimes you do get amazed by in what mysterious ways that nature works. This weekend has been on of those times when I get that “wow”-feeling while at the rig. One of my fascinations about this hobby is just the “nature” part of communicating with distance stations, the way we use nature and natural phenomenons to reach distance places. Combined with transmitting with low output power the fascination is, at least for me, complete.

As a preparation for the SSMS, Swedish Lakes activity, I have been working some JT9 with my FT-817 this weekend, letting the  IC-7410 rest in the shack. I just LOVE working the WSJT-modes with the FT-817 and QRP which makes it bit more of a challenge sometimes, especially when working JT65 on the more popular bands. While making some sporadic CQ:s on the 20m JT9 section I got a respons, and I did have to look twice to be sure,  from a YF3-station (Indonesia)! That is some 11200 km distance and with a nice reception report aswell! My setup was only 4-5 W into a (for the 20m-band tuned) GP-1500 vertical. Well, this was really a “Wow” for me! 🙂

As I am using the PSKreporter service quite frequently during my activity it’s even more intriguing to see this response for just airing your call for a couple of hours… 🙂

20m jt9Ham radio  really is a “World wide Hobby” in a sense..  😉

This weekend seems to have good propagations, especially towards the east of the US and east of Canada. For some reason the Canadian stations are generally hard to come by unless they are located in the eastern part, near the US.

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. 🙂

QSO with the creator..

No, im not religious and the gods haven’t started with Hamradio. At least not to my knowledge. 🙂

The creator in this case is K1JT who has created the digital JT modes and I had the privilege to work this gentleman using JT9 on the 20m band today. Actually he was the first caller to a CQ on the JT-modes after a week of practically no radio activity at all.

This was a fun way to start of the weekends radio activity. 🙂
