WSJT-X – Extended

After using WSJT-X for the modes JT65/JT9 now for a couple of time and done more than 1000 contacts in these modes, one drawback occured to me: The Logbook function when you worked stations more than once on different band/mode slots.

When you worked¬†a station for example on 20m in JT65, the build in logbook will show you this call in green, meaning you worked it before, even if you are now on 15m in JT9. So the only meaning to this is yes, we worked before, but no chance to see where and in which mode ūüôĀ

As I’m running an online logbook at the idea was to make a lookup in this database for the stations calling CQ in WSJT-X.
The following shows the concept of a software written in C++.

WSJT-X logs every station activity in the ALL.TXT file, so the task was to write a piece of software which is able to scan the ALL.TXT for the latest CQ-calls in the actuall time slot and make a lookup in the MySQL-database at

Typical WSJT-X receive window, frequency was 10.138 MHz.

You see F4FSY calling CQ in JT65 mode, the call is in green colour which indicates we worked before.

My program showing the CQ-calls, and after a click at F4FSY, the result of the MySQL database query.

OK, F4FSY an me worked before, but on 14 MHz in JT9 mode, so no problem to work him on 10 MHz for a new band.

Another idea occured to me when calling CQ by myself on a quiet band. You constantly have to monitor the PC Screen if someone is answering your call, maybe you want to use your time for doing some other work while calling CQ.

So my little program was extended to scan the ALL.txt for incomming calls as well, giving an audio-alarm if there is a station answering my CQ.
Runing my station mostly remote, I desided to go for a Client/Server soloution, so the alarm can be heard on the RDP-Client instead on the PC in the shack running WSJT-X.

Client connects to the above program at startup, showing the call of the answering station an start an alarm tone.

Last but not least, why not automaticly updating the Internet-Log?
WSJT-X maintains an ADIF file where all the QSO’s were stored. So my software monitores any change of size of the file WSJT-log.adi, reads the last line of the file and calls a PHP file at my website which writes this data to the MySQL database. Done!

Next option to include is to scan the WSJT-X internal log when there is no internet connection¬†available. In this case you won’t see if you worked a¬†call before in CW or RTTY but at least where you worked him in JT65/JT9.


EX/DK7UY – Kyrgyzstan 1995

Where dou you go next?

That question was asked by Willi, DF8WS, during a meeting at the 1995 Ham-Radio in Friedrichshafen.
‘I don’t know yet’ I answered and Willi said ‘Why not go to Kyrghyzstan?

A former USSR republic? Sounds good.
I contacted my friend Helmut the next day ‘Why not, but where is Kyr.. what’s the name of this country???’ was his statement.
With Willi’s help, I got in touch with Serge, EX2A, who officialy invited us to visit his country, offered to stay at his home and promised to help us with the licence.

After some problems with the visas (The Fax at the foreign ministry in Bishkek was out of service…), bokking flights with Kyrghyzstan-Airlines (Yeah, an old Tupolev…) and not to forget an three weeks chrash course in Russian language, six weeks after the ‘Where do you go next?’ question, Helmut and I were waiting in front of the check in counter at Hannover airport.

‘What bussines are you going to do in Bishkek’ the German custom officer asked us and you could tell by the look in her face that she didn’t belive us a word, when we told her the story about beeing on a amateur radio mission and not on a bussines trip.

But finaly we boarded the good old Tupolev a had a lift of to Bishkek.

4U1ITU – I.T.U. Geneva 1988-1995

From 1988 to 1995 I had the honour to be one of the more regular operators of 4U1ITU, the station of the International Amateur Radio Club at the
ITU headquaters in Geneve, Switzerland.

Beside the 4U1ITU callsign I activated the following special calls:
4U3ITU (1988)
4U4ITU (1989)
4U5ITU (1990)
4U6ITU (1991)
4U7ITU (1992)
4U8ITU (1993)
4U9ITU (1994)
4U0ITU (1995)

Special thanks for making every stay in Geneve a pleasant one go to:

and of course to the crew at ITU headquarters
