2021-04-05 I participated in the EA RTTY contest 2021 1 month ago
RTTY Contest on websdr Last weekend was the EA RTTY Contest 2021 edition. I decided to participate because I appreciate the contests organized by the Unión de Radioaficionados Españoles.

Participation time was somewhat limited due to other things happening in the easter weekend. In the end I made 79 contacts and entered my log in the 'SINGLE ALL LOW POWER DX' category. As 'low power' is defined as 'below 100 watts' and my RF amplifier isn't working at the moment this is the fitting category.

Update 2021-05-05: Results are in: 71 valid contacts, 117 qso points and 51 multipliers: rank #225 of the single operator multiband low power DX category.

2021-04-04 New country in the logs: South Korea 1 month ago
Another case of having luck and being at the radio at the right time and frequency: I saw a few stations from South Korea show up in FT8. Tried making contact with more than one of them and the second or third station became stronger after a few minutes and with some trying the contact was made with HL5BLI.

It was a really short opening, five minutes later I saw no traces of stations from South Korea.

Update 2021-04-05: And the contact is confirmed on Logbook of the World too.

2021-03-29 A serious recumbent bicyle ride 1 month ago
GPX viewer result of my recumbent cycling trip 2021-03-29 I recently wanted to do some serious cycling to improve my mood and raise my maximum distance per day again. So I found a day off and set a goal of riding more than 100 kilometers. With a bit of planning on the map I decided that Utrecht - Hilversum - Bussum - Almere - Nijkerk - Utrecht was a good way to get about 105 kilometers cycling.

In the end the odometer stopped at 112.53 kilometers. And I do feel better.

2021-03-28 Chasing awards: the full set of SX1A .. SX9A in the log 1 month ago
With some alerts set to get the last of the Special Event Station series to celebrate the 200th anniversary of Hellenic War of Independence against Ottoman Turks in the log I now have the full set: at least one contact with each of the special event stations.

Which means the website will generate a nice digital certificate for me which I could print out and hang on the door of the room where I have my radio setup. But that door is already filled so I'll just keep the digital certificate and leave it at that.

It was fun chasing them! My thanks to the organization behind this.

2021-03-27 The paddle works on the radio too! 1 month ago
Making a video about my new paddle is one thing, actually using it with the radio is another. I have seen radio amateurs buy expensive morse gear and finding out that learning morse is hard.

I connected the paddle to the radio via the nanokeyer I built and called CQ in a part of the 20 meter band where I expect other users with slow speed.

After one CQ I got an answer from PA5ABW Ab. The same person who taught me morse code!

2021-03-27 I bought a secondhand morse paddle and made a video about it 1 month ago
For a while I had a notification set for someone selling a morse paddle. Finally one came along at a reasonable price so I bought it.

And.. I mentioned this detail to some people at work. Who had an idea of what a morse key is, but didn't know about morse paddles. So with my big mouth I said "I'll make a video about it". This was triggered by the fact that I recently learned about OpenShot non-linear video editor which is available for Linux too.

So I created a video. And found out making a video of 30 seconds is a lot more work than 30 seconds. I watched some tutorial videos about OpenShot first and thought about what I wanted to show. I haven't added spoken comments because I didn't feel like doing those too.

The video isn't great, I can see several beginner mistakes. But I get the point across of what a paddle does. There is a continuity problem because I used sunlight. Which isn't very constant. And I made several clips because I didn't think I would get everything I wanted to show right. But now there are changes in light and a bit in camera angle, even with using a tripod.

And our neighbours were busy hammering indoors, so that can be heard too.

2021-03-24 New country in the logs: Hong Kong 1 month ago
It is always good to have a bit of luck and get a contact with a new country. This evening I saw a call from Hong Kong pop up on my screen with FT8 traffic and made the contact with a bit of a hickup since it was hard for me to receive the transmissions. The signal report showed that my signal made it across easier, so I had confidence and the contact was made.

After that I saw a station from Ghana, which had more trouble decoding my signals, but after a few tries that contact was valid too. Ghana is not a completely new country for me, but it was new on the 40 meter band.

Now to wait for digital confirmation (both show they use Logbook Of The World) and see if I can get a QSL card.

Update: I just noticed I didn't write about a few new entities from recent months. In February I also got Anguilla in the log (an island in the Carribean) and confirmed. This was a case of turning on the radio on a non-standard time and seeing a new country and getting the contact. In March I saw notifications for activity from the UK bases on Cyprus (which are two British overseas territories housing military bases because of the strategic location of Cyprus) which I have been chasing for a while and the contact was made.

Update: All contacts mentioned above confirmed.

2021-03-17 Upgraded another system at home, now serving webpages with TLSv1.3 1 month ago
Encrypt all the things meme After the recent work on updating the TLS settings for the webservers at home there was one element missing: TLSv1.3 support.

This needed an upgrade of openssl and the 'easy' way to get there was a full upgrade of the server running the external facing proxy. So I took that step yesterday evening. Made a snapshot first and started upgrading devuan ascii to beowulf.

After the update a lot of things were broken: I defined a non-standard location for bind9 logging and AppArmor disagreed. Without a working nameserver a lot of stuff breaks internally! So after managing to get on the upgraded system with console I changed the AppArmor rules to allow it. After that things started again.

For the next time I manage to break the resolving nameserver: I should remember that avahi/multicast dns works on most systems even when DNS resolving fails. I checked and I can use .local names to get to the right equipment.

After checking how everything is running for about a day I threw out the old snapshot.

2021-03-14 I participated in the EA PSK63 Contest 2021 2 months ago
As a number of years before I participated in the EA PSK63 Contest 2021. This is a contest organized by the Spanish Amateur Radio Club Unión de Radioaficionados Españoles and I appreciate their work in this and other contests.

Contacts were made Saturday afternoon/evening and Sunday morning. I decided to go for both 20 and 40 meter band to improve my contest results.

In the end I made 148 contacts, 58 on the 20 meter band and 90 on the 40 meter band. To my surprise when I started Sunday morning there was very little activity on the 20 meter band, but the 40 meter band was already filled with noise, probably from nearby solar power installations. With a bit of timing and luck I could work around the noise peaks and make contacts with the stronger stations. Later in the morning there was a lot more activity on the 20 meter band and new stations rolled in.

It was good to see a lot of to me new Spanish callsigns in this contest. I guess amateur radio in general and contesting has grown in Spain.

2021-03-11 Sendmail 8.15.2 in Ubuntu 20.04 not even trying IPv6 2 months ago
I needed a virtual machine with ubuntu so I did the base installation and also configured unattended-upgrades and sendmail to get the results. But I noticed after a while I never saw any mail from that machine.

Problem soon found:
mailer=relay, pri=30131, relay=postbode.idefix.net. [82.95.196.202], dsn=4.0.0, stat=Deferred: Connection timed out with postbode.idefix.net.
The machine wasn't even trying to reach the mailserver over IPv6! On the internal network with servers it will fail over IPv4 because of the portforwarding rule for the port from the outside IP to the mailserver but I never expected an internal machine to try IPv4.

Somehow this seems default for sendmail 8.15.2 in Ubuntu 20.04. I could find someone else asking this: No IPv6 outbound from Sendmail starting with 20.04 but no answers how/why.

At first I suspected systemd-resolved as the old saying goes that all sendmail problems are caused by DNS. But disabling that didn't fix the problem.

I now have the IPv6 address hardcoded in the configuration, that works.
dnl FEATURE(`msp', `postbode.idefix.net', `25')
FEATURE(`msp', `[2001:980:14ca:1::23]', `25')
I also found out the option ResolverOptions=+WorkAroundBrokenAAAA was set but not causing this.
