2017-02-24 Seeing the same amateur stations in contests 6 hours ago
As I process the eqsl confirmations that come in after the Russian Worldwide PSK contest 2017 I start to notice some callsigns are showing up regularly in (digimode) contests. My highest number of confirmed contacts via eqsl which are related to contesting come from YO9AGN, S58X, S51AF, RA3GZ, HG3FMZ, EA3HKa, 9A4FS.

But the number one callsign I have confirmed via eqsl is not a contest station but the Veron club station PI4AA where I try to call in to the net almost every month.

2017-02-23 Ok, not using the available wind meter readings in the neighbourhood 21 hours ago
Today is very windy in the Netherlands, with storm with wind gusts of up to 65 km/h and average windspeed of 36 km/h. But the readings shown by the weather station readings shared in the neighbourhood show quite different values:
2017-02-23 21:49:14 :   HIDEKI Wind sensor
        Rolling Code:    15
        Channel:         4
        Battery:         OK
        Temperature:     4.9 C
        Wind Strength:   15.29 km/h
        Direction:       337.5 °
So I don't think those will help a lot for my Weather station Utrecht Overvecht.

2017-02-20 I participated in the Russian Worldwide PSK contest 2017 3 days ago
This weekend I had time to use the radio and after trying to get some more contacts on the 30 meter band Friday evening I decided to participate in the ongoing digimode contest in the weekend. This was the weekend of the Russian Worldwide PSK contest 2017 (https TLS certificate is broken at the moment).

I had fun doing it, had 124 contacts in the contest. I now have two new countries in the log: Kuwait and Suriname. And Kuwait already confirmed via Logbook of The World. I just uploaded the log (with the last contact rejected as it was too late):
Band  QSOs Dupes Points Mults
160      0     0      0     0
80       0     0      0     0
40      52     0    320    28
20      71     0    223    33
15       0     0      0     0
10       0     0      0     0
======================================
Total  123     0    543    61
Claimed score is 33123 points
Comparing it to my results in the Russian WW PSK contest 2015 I did a lot better. At that time I still had limited access to the 40 meter band which limited my options for PSK traffic.

2017-02-15 JT65/JT9 on 30 meters, even getting a new US contact 1 week ago
Today I threw out the longwire antenna and tuned it for the 30 meter amateur band (10.100 - 10.150 MHz). I first tried the PSK part of the band but that was completely silent. I tried the JT65/JT9 part, and that part was buzzing. And beeping, and other sounds. I made several contacts in Europe in the morning which was as expected. But in the evening the computer/radio was still running and I noticed some US callsigns, and answered one, and had a JT9 contact with K8SIA.

After that it was time to get the longwire antenna back in the house again. All in all another good experience with the 30 meter band.

2017-02-12 Rising number of amateur radio contacts 1 week ago
I noticed recently the number of radio contacts made by my new callsign PE4KH which I started using in March 2016 was getting close to the number of radio contacts made by my previous callsign PD4KH between March 2013 and March 2016. A typical rise in contacts, mostly due to my skills improving and participating in contests. So I wanted to view the rise per month and did some searching how to ask the cqrlog databases and plot the results.

Oh, and now PE4KH has more contacts after a few new contacts logged in PSK31 mode on the 20 meter band today.

2017-02-06 I participated a bit in the Vermont QSO party 2 weeks ago
Vermont counties map
Vermont Counties map, from Vermont county map - Wikimedia
I still try to make radio contacts to far away places even with current radio propagation at low levels. At the moment the last hours of the afternoon before sunset seem to give options towards the west (USA and Canada).

Last week I got home early one day, fired up the radio for PSK31 on 20 meters and saw K2EQ again.

This Sunday I saw in the fldigi screen:
CQ Vermont QSO Party K1VMT K1VMT
and answered with my call without having any idea what the Vermont QSO party is about, but having Vermont in the log would mean a new US state.

The exchange was made and I dug up from the noise that the answer included LAMoille which is a county in Vermont. It all made a lot more sense when I viewed the Vermont QSO party website. I kept an eye open for CQ's from other Vermont stations but never saw any. So I entered my log with one entry for the Vermont QSO party.

2017-02-06 Squeezing a bit more powersaving from Linux 2 weeks ago
The c't magazine this month had a few tips on linux powersaving. I tried them on the homeserver and saw indeed a very slight reduction in power use as logged by the UPS.

For powersaving in sound card(s):
# echo 1 > /sys/module/snd_hda_intel/parameters/power_save
This can cause plopping sounds on some sound cards.

For powersaving in disk communication:
# cd /sys/class/scsi_host/
# for i in host*/link_power_management_policy; do echo min_power > "$i"; done

2017-01-27 Nice neighbours sharing their weather readings 3 weeks ago
A posting about reading 433.920 MHz signals triggered the idea I had ages ago to decode those signals and see what weather stations are available nearby. The original posting 433,92Mhz ontvangen (Dutch) was about receiving remote controls (KlikAanKlikUit) and had a screenshot of some Linux software for receiving those signals but no name of the software (that would be useful information).

But a simple google search found me rtl_433 on github which receives and decodes all kinds of signals on 433.922 MHz.

I downloaded it on the raspberry pi for radio experiments, and it is working fine receiving weather information from probably nearby weather stations. At least one outside temperature and humidity sensor, one inside temperature and humidity and one wind and temperature sensor. This last one could be nice for my weather station!

2017-01-23 Ontbrekende stukje grotere MTU met VDSL op DrayTek Vigor 130 en Ubuntu 1 month ago
Ongeveer een jaar geleden ging ik over op het Draytek Vigor 130 VDSL modem om weer een configuratie te krijgen waar ik maximale controle heb.

Het nog openstaande punt is dat ik de ppp configuratie graag naar een MTU van 1500 bytes wil. En dat dat toen niet lukte in Vigor VDSL modem in gebruik en Xs4all VDSL met DrayTek Vigor 130 VDSL modem en PPP eindpunt op Linux (ubuntu) server.

Wat ik al goed had was de MTU van de ethernet interfaces hoger en het vinkje op de Draytek aangepast. Maar als ik de mtu/mru hoger forceerde in de ppp opties ging het mis.

Nu kwam voorbij in xs4all.general over dit onderwerp:
> 1500 wordt ondersteund door Xs4all en je test eerst bij 1492 welk pakket
> via ping erdoor gaat zonder in stukken gebroken te worden.
> Daarna zet je de MTU naar 1500 en kijkt of je inderdaad 8 bits meer door
> router kunt drukken zonder dat die gebroken wordt.

Wel zorgen dat het apparaat waar je de PPPoE termineert RFC4638
implementeert.
Die moet dan in de PADI een extra tag plaatsen (PPP payload is 1500
bytes), en de BRAS zet dat ook weet in zijn PADO antwoord.
Zo maar een grotere MTU gebruiken gaat niet werken...
De PPPoE sessie komt bij mij vanaf de thuisserver met rp-pppoe. Even zoeken leverde mij op dat voor rp-pppoe met MaxPayload onderhandeling ik minstens 3.11 nodig heb, en bij de huidige ubuntu versie zit nog 3.8. Tijd om een nieuwere versie te testen.

Update: Daarvoor moeten zowel de pppoe binary als de rp-pppoe.so plugin voor pppd bijgewerkt worden, en dat lukt me op dit moment even niet. Gelukkig had ik de oude pppoe binaries expres klaar staan en kon ik dus heel snel terug.

2017-01-22 En nog even over stadsverwarming 1 month ago
In Geluidsoverlast van vliegtuigen had ik het vooral over het opsporen van het vliegtuig om de klacht te kunnen melden, maar er was nog een extra detail: het vliegtuig vloog om deze tijd en bij deze lage temperaturen (het vriest momenteel ook overdag) om warmtelekken in de stadsverwarming te vinden.

Ik kan zo wel vertellen dat de stadsverwarming een groot warmtelek is, er zijn keurige strepen hier door de wijk waar het nooit vriest omdat de leidingen er onder liggen. Erg aardig van Eneco, maar degenen die veroordeeld zijn tot stadsverwarming betalen er wel de hoofdprijs voor.

Mijn ervaring met stadsverwarming is dat het voor hetzelfde warmtegebruik veel duurder is dan aardgas of electriciteit en dat het met een bijzonder lage efficïentie getransporteerd wordt. In mijn vorige huis (een flat) had ik stadsverwarming die zoveel warmte lekte op allerlei manieren dat ik de hoofdkranen ervan tot het minimum had dichtgedraaid en dan ergens in November wel eens het raam dichtdeed omdat het toch wel fris begon te worden. Maar omdat het blokverwarming was (een stadsverwarmingsaansluiting voor het hele gebouw en een verdeelsleutel voor het warmtegebruik per appartement) betaalde ik wel meer dan 100 euro per maand voor de warmte die ik zo snel mogelijk afvoerde.

Toen ik van een appartement naar een woonhuis ging was ik ineens een stuk minder per maand kwijt voor warmte omdat dat woonhuis een hoog rendement verwarmingsketel heeft.

Van een andere gebruiker van stadsverwarming momenteel weet ik dat die een absurd hoog bedrag betaald om het een beetje redelijke temperatuur te krijgen.

2017-01-21 Geluidsoverlast van vliegtuigen 1 month ago
Het gebeurt van tijd tot tijd dat we hier extra lang en veel herrie van een vliegtuig of helikopter hebben. Vanavond weer iets waarvan we ons eerst afvroegen of het een helikopter of een vliegtuig was, maar wat wel heel hardnekkig in de buurt bleef vliegen.

De website van de rijksoverheid met de vraag Waar kan ik terecht met klachten over geluidsoverlast van vliegtuigen? is niet heel behulpzaam:
U kunt klachten over geluidsoverlast van vliegtuigen melden bij het vliegveld waar die vliegtuigen opstijgen of landen.
Het onhandige is alleen dat standaard niet zo goed aan een vliegtuig te horen of te zien is van welk vliegveld dit is opgestegen.

Maar, ik heb meestal dump1090 draaien om transpondersignalen van vliegtuigen te ontvangen en daarin zag ik meer informatie: geen latitude/longitude (altijd verdacht) maar wel hoogte (hardnekkig 1600 voet = 625 meter). En ook de ADSHEX code: 458D73 waarmee ik het vliegtuig en de vlucht snel kon vinden: Romaero BN-2-A-21 (OY-CKS) - planefinder.net wat aangaf dat het vanaf vliegveld "Rotterdam the Hague airport" komt. De website van dat vliegveld is vooral voor passagiers en niet voor meldingen geluidsoverlast, maar met wat zoeken kwam ik terecht bij Veel gestelde vragen over klachten rond vliegverkeer Rotterdam-The Hague Airport met een keurige verwijzing naar het klachtenformulier wat zelfs heel modern de optie heeft om de vlucht op de kaart te vinden aan de hand van mijn postcode. Daar heb ik de klacht ingediend, want het was echt langdurige herrie.

En dan blijkt er uitleg te zijn via een andere bron: Eneco vliegt dit weekend boven Utrecht en Nieuwegein met de mooie bewering:
Het is de eerste keer dat Eneco een inspectievlucht boven deze regio maakt. Het gaat om een klein en stil vliegtuigje, zegt Eneco, maar de vluchten kunnen wellicht voor enige geluidsoverlast zorgen.
Ze vliegen met een propellorvliegtuig uit 1978, dat is wel klein maar absoluut niet stil.

2017-01-20 APRS on the Raspberry Pi: trying to decode APRS packets 1 month ago
So the mobilinkd is now connected to serial over bluetooth on the Raspberry Pi, but now to get APRS data into aprx.

So far aprx does start but I see absolutely no data coming in, even when aprsdroid will see traffic. Something strange.
koos@joy:~ $ sudo aprx -v
2017-01-20 22:05:10.593 aprx start - 2.9.0
2017-01-20 22:05:10.594 TTY /dev/rfcomm0 opened
2017-01-20 22:05:20.624 CONNECT APRSIS aprsc.pa4tw.nl:14580
^C
2017-01-20 22:18:06.115 aprx ending (SIG 2) - 2.9.0
2017-01-20 22:18:06.116 aprx ending (SIG 2) - 2.9.0
It's a good thing aprsc.pa4tw.nl has an IPv6 address as this Raspberry Pi is only configured for IPv6.

Testing with minicom on /dev/rfcomm0 does show the startup messages from the mobilinkd but absolutely no APRS data in KISS format,,,
== BeRTOS AVR/Mobilinkd TNC2
== Version 2.0.1.571
== Voltage: 4019mV
== Starting.
Switching the mobilinkd between the Raspberry Pi and the smartphone with aprsdroid does seem to confuse something, it's not always showing data in aprsdroid either.

Installing the Linux ax25-tools and using kissattach and configuring aprx to use that interface doesn't help either.

Back to the KISS over serial port over bluetooth config I changed the setting 'bluetooth tracking' on the mobilinkd, which is advised for digipeater setups. And now I am seeing something:
koos@joy:~ $ sudo aprx -v

And the results are showing up via the aprsc dashboard on aprsc.pa4tw.nl. Almost all packets I receive and forward are rejected as duplicate packets, but I have seen some packets accepted. So I guess I'm not really needed as an I-gate.

2017-01-20 APRS on the Raspberry Pi: talking to the mobilinkd 1 month ago
So I want to run APRS on the Raspberry Pi. My ultimate goal is to announce the meeting of our local radio club over 2 meter APRS but I will start with just playing "I-gate" which means I receive messages over the air and forward them to the nearest APRS server on the Internet which will then probably reject them because I'm not the only one receiving them.

The first step is to link the Raspberry Pi to a radio. The easiest way is (in my opinion) to link using the mobilinkd which uses serial over bluetooth, something the Raspberry understands.

I looked up how to use bluetooth on the raspberry and found Installing Bluetooth - Raspberry Pi Projects but using the suggested graphical tools requires a lot of packages:
koos@joy:~ $ sudo apt-get install bluetooth bluez blueman

I don't need the whole graphical environment (I run my Raspberry Pi headless, so it doesn't have a graphical environment).

So I searched some more and found the command bluetoothctl which does pairing in text mode, exactly what I want. It took some trying:

So I have to set 'scan on', 'pairable on' and 'agent on' to get in a state where a 'pair' command will start the bluetooth pairing process and ask for a pincode.

Now we have a pairing, and I could add a serial connection over this. By hand this can be done with commandline rfcomm:
koos@joy:~ $ sudo rfcomm connect /dev/rfcomm0 30:14:11:xx:xx:xx
Connected /dev/rfcomm0 to 30:14:11:xx:xx:xx on channel 1
Press CTRL-C for hangup
And in another terminal:
koos@joy:~ $ cat /dev/rfcomm0 


== BeRTOS AVR/Mobilinkd TNC2

== Version 2.0.1.571

== Voltage: 4045mV

== Starting.

So there is communications possible! Now to get aprs data from the mobilinkd. This should happen via the KISS protocol, but at this time I have no idea what that would like.

2017-01-19 (Does anybody have experience with multi-operator logging with fllog from fldigi, especially in digital...) 1 month ago
Google+Koos van den Hout : Does anybody have experience with multi-operator logging with fllog from fldigi, especially in digital-mode contests?

In a discussion about digital-mode contesting I looked at fldigi and fllog, but searching for experiences in contests with fllog I find nobody who writes about their experiences (negative or positive).

http://www.w1hkj.com/FldigiHelp-3.21/html/ui_configuration_log_server_page.html#logbook_network_address

I'm a reasonably satisfied user of fldigi in digital-mode contesting but I haven't run a multi-operator digital-mode contest yet.
2017-01-16 Living in two timezones 1 month ago
PyHamClock Radio amateurs who make contacts over the borders constantly live in two timezones: both their local timezone and the UTC timezone. Logging contacts with UTC timestamps ensures the timestamps align across different parts of the world.

To help with this logging programs for amateur radio like CQRLOG will show the current time in UTC and log in UTC.

But I also like having a desktop clock in Linux with both the local time and the UTC time. One of the reasons is with WSJT-X: in this mode transmissions start at second :00 and end at second :50 so I have to check the WSJT-X screen every minute between seconds 50 and 00 (or every second minute when I'm in a contact). This gets tedious and I get distracted when there is 50 or 110 seconds to just wait.

There are hardware 'amateur radio' clocks like the CK-2 LED Digital Dual Time Zone Clock which is over 200 US dollars and looks like it would fit into a missile launch command center. Or from MFJ: MFJ-148RC dual time LCD clock, atomic W/GMT ZONE, id timer at nearly 60 US dollars.

I decided to just look for some software for this task and after a few searches I ended up with PyHamClock which is now running on my amateur radio desktop system.

2017-01-15 I participated in the UBA PSK63 prefix contest 2017 1 month ago
I had the UBA PSK63 prefix contest in my planning again this year. This year I set up the antennas in advance, checked the contestmacros and I was ready. Some things at home delayed the start a bit, so I did not fire of a CQ UBA PSK63 PFX TEST right at 12:00 UTC but I managed nicely.

In the end I made 133 contacts. I started on 20 meters but that 'dried out' soon especially after the sun started to come down. I switched to 40 meters and this was the first time in this contest that I had access to the part of the 40 meter band below 7.050 MHz, which is where all my 40 meter contacts were made. Late in the evening 40 meter started showing some more distant stations, I saw Indonesia and Surinam callsigns but they did not hear my reply (which was not for lack of trying).

Total 133 contacts, 59 on the 20 meter band and 74 on the 40 meter band, so I entered as SOAB (single operator all band). A simple script counts 65 prefixes on 20 meter and 52 prefixes on 40 meter so that would make my total score 15561 points.

Looking at my contesting results the rates of contacts are improving (even with radio propagation getting worse) so I think I am doing fine.

2017-01-11 Debugging a crashing cqrlog 1 month ago
This morning cqrlog crashed soon after I started it. On a restart it crashed instantly without even giving me any option to select anything.

Since there was some mysql corruption in my system anyway I decided to completely wipe out the databases/configuration, start over, import the backups again and be on my way. I never got that far, every time shortly after initializing cqrlog it started crashing. So I started testing what could be causing this and ended up with the DXCC update being the cause. So I did not do this update, loaded my logs from the backup, improved some things in my configuration and reported my findings via mail to de cqrlog developer. I can live with the DXCC tables being somewhat outdated, I have contacts with stable countries here in Europe.

I hope an update comes out soon for cqrlog. Also noted in the cqrlog forums where at least one other user has seen the same workaround. I haven't posted it on the forum yet as I wasn't registered there.

Update 2017-01-12: During the day an update for cqrlog was made available which fixes the problem. Applause to the developers of cqrlog for responding this fast.

2017-01-09 I participated in the ARRL RTTY Roundup 2017 1 month ago
This weekend I wasn't planning on radio contesting but some other plans got changed and in the evenings the 40 meter band around 7.040 MHz was filled with the deedle deedle of RTTY signals. It was the ARRL RTTY Roundup so I participated some hours. Given the limited time and the not so optimal propagation I did not expect a top score.

In the end I made 62 contacts. Better than my score in the ARRL RTTY Roundup 2016 where I made 24 contacts (after logs were checked).

2017-01-05 Outdoor and cold amateur radio 1 month ago
Today I had time for outdoor amateur radio but it was a bit cold. So I took the car to recreation area "De Leyen" near Groenekan again, which I also did in April 2015 with warmer weather.

This time it was cold enough to stay in the car and still get cold after a few hours. I tried and worked 20 meter PSK31 and SSB, and again had the luxury of the environment there being almost free of radionoise on 20 meters. On 40 meters it was quite different, the only thing I heard from the radio was the typical noise of electrified wire nearby.

No loads of contacts, PSK31 wasn't very busy. I had the advantage of hearing stations a lot better on SSB (voice) but they did not hear my reply over the pile-up of other stations trying to contact them. I heard VP8LP which is impossible for me to hear at home, but he did not hear my replies.

The interesting contact was with A70X which is a radio expedition to Al-Safliyah island in Qatar.

2017-01-04 Reviewing my 2016 amateur radio resolutions, and the new ones for 2017 1 month ago
Mobile radio for 2m/70cm in radio shack, CC-BY-SA Again on reddit /r/amateurradio there was a thread HNY! What are your 2017 Amateur Radio resolutions? so I checked the results for My 2016 Amateur Radio resolutions and thought about what I want to do in 2017 with amateur radio.

So, first to review what I hoped to do in 2016:
  • Pass the exam for the full license on 2 March
Passed.
  • Participate in "Mills on the air" in May
Prepared, and failed: antenna wasn't working and by the time things were fixed the 40 meter band wasn't cooperating.
  • Making amateur satellite contacts when the weather permits
No contacts made, I got an antenna rotor and built a holder for the arrow antenna on that rotor, but I only used it to receive SSTV from the ISS.
  • Participate in a few digimode contests 'seriously' (preparing, using an outside antenna, optimizing score). Sofar I usuallly go 'oh there is a contest I'll throw in my call and see if I can score some points'
Done: did better in a few contests compared to my 2015 scores. Also worked on and improved my contest macros. I even did a little voice contesting.
  • Bring some radio stuff on summer holiday (a full license makes this possible in a lot more countries around here)
Brought the radio and an endfed antenna on a holiday in northern England. Found out the endfed gets into problems when cold (which was probably also the reason "Mills on the air" failed first). And by the time the weather was nice enough for the endfed to work again the battery of the radio was drained.

So, for 2017:

2017-01-01 DAB services scan 1 Januari 2017 1 month ago
DAB+ logo Ter ere van het aanzetten van de zender Lopik te IJsselstein voor de regionale multiplex Randstad een nieuwe scan. Van de regionale multiplexen komen 6B Oost-Noord NL en 7A Zuid NL ook goed genoeg binnen bij een scan met een antennelocatie zo hoog mogelijk aan huis.

Condities zijn duidelijk anders dan bij de DAB services scan 11 November 2016: dit keer zijn de regionale multiplexen 6B Noord-Oost Nederland en 7A Zuid NL goed genoeg om te kunnen luisteren, en zijn de andere MTVNL multiplexen niet eens gezien.

2017-01-01 Leaped into 2017! 1 month ago
Jan  1 00:59:59 greenblatt kernel: [2538111.748198] Clock: inserting leap second 23:59:60 UTC
I usually distribute the leap second file to all servers I control to make sure there are no strange problems around it.

I wish everyone a good 2017!
