2020-11-25 New "country" in amateur radio: Jan Mayen 2 days ago
I still have a (short) list of European "countries" that I not yet have an amateur radio contact with. Jan Mayen was on that list and I set a specific alert in HamAlert to let me know when signals are seen from that part of the world. Today the alert fired and I had time to operate the radio. JX2US was active on 20 meter FT8. I joined the load of stations calling him and got an answer and a valid contact after trying for a while.

Jan Mayen is a very northern island belonging to Norway, but for amateur radio it is a separate entity. Jan Mayen has no permanent residents. According to the JX2US qrz page he does amateur radio in his spare time outside work in shifts.

2020-11-20 Ander VDSL modem van xs4all 1 week ago
Ik bleef er last van houden dat bij iedere activiteit met zenden op de radio het modem de verbinding verbrak en weer op moest bouwen. Eerder was dat een keer per week per band waarop ik actief werd maar de laatste tijd lijkt het bij frequentiewijzigingen of gewoon bij activiteit nog veel meer te gebeuren.

Ik weet wel een simpele oplossing: de aanbeveling in hoofdstuk 7.2.1.2 van ITU-T Recommendation G.993.2 uitvoeren: instellen dat alle amateur banden compleet overgeslagen worden en dat daar geen signaal aanwezig mag zijn (zogenaamde notches).
VDSL2 transmitters shall be able to reduce the PSD of the transmitted signal to a level below −80dBm/Hz in 16 arbitrary frequency bands simultaneously. An example list of frequency bands (the amateur radio bands) is shown in Table7-1.
In ITU G.993.2 zit een keurige lijst van amateur frequenties onder de 30 MHz die bijgewerkt is naar de huidige stand van zaken.

Dus ik had dit in een contactverzoek naar xs4all gezet. Maar zo makkelijk doen ze dat niet. Ze zien dat ik een ander modem gebruik (klopt, de Draytek Vigor 130) en dat het modem wat ik van hun heb verouderd is (klopt, een fritz!box 7360v1). Dus ze sturen eerst een nieuw Fritz!box 7590 modem op, daarmee kan ik dan testen wat de stabiliteit doet en dan weer contact opnemen als de problemen blijven.

Ik ben benieuwd. Ik zie veel meldingen van collega-zendamateurs dat ze notches laten instellen om zo van stabiliteitsproblemen af te zijn. Ik heb het idee dat in het afgelopen jaar ergens een update naar de DSLAM is gegaan die ervoor gezorgd heeft dat dit makkelijker onderbrekingen geeft, en bijvoorbeeld ook de samenwerking met de Draytek Vigor 130 met modem8 driver moeilijker maakte.

Verzoek in de doos is om het 'oude modem', dus de fritz!box 7360v1 te retourneren. Ik weet niet eens zeker of ik die in bruikleen heb van xs4all of dat dat toen nog een 'gratis' modem was maar ik ga er verder toch niets mee doen dus ze kunnen het modem terugkrijgen.

Update:

Na wat prutsen met de configuratie heb ik iets werkends met de fritz!box 7590. Eerst maar eens een standaard configuratie met de fritz!box 7590 zodat ik een firmware update kan doen. Daarna op zoek naar de gewenste configuratie waarbij ik de PPPoE sessie zelf afhandel op de server.

De fritz!box heeft wel de optie om PPPoE passthrough toe te staan maar als tegelijkertijd de PPPoE client in de fritz!box zelf een verbinding opzet is de PPPoE sessie al in gebruik en heb ik nog niet mijn gewenste verlegde eindpunt van de verbinding.

Oplossing: niet configuratie voor xs4all kiezen maar een onmogelijke configuratie gebaseerd op 'andere internetaanbieder' met vlan-id 6 en ik heb gekozen voor 'bridged' plus PPPoE passthrough. Nu mag ik wel de verbinding opbouwen vanaf mijn eigen router. En klaagt het modem dat het geen internet verbinding heeft.

De fritz!box onderhandelt wel impulse noise protection (G.INP) met de DSLAM en mag ook dynamisch de downstream snelheid aanpassen bij storing (Seamless rate adaptation). Met actief worden over diverse stukjes van de 40 meter band krijg ik het modem nog wel aan het verbreken maar uiteindelijk is de verbinding stabiel terwijl ik met de radio actief ben. De impulse noise protection valt me wel op: met de Draytek Vigor 130 was dit uitgeschakeld.

Het nadeel is dat de MTU van de verbinding nu weer 1492 is want de fritz!box ondersteund niet een ethernet MTU van 1508 voor PPPoE passthrough. Helaas. Het voelt als een beetje net-niet oplossing als zo'n detail niet klopt.

2020-11-08 RF knowledge helps fix completely different problems 2 weeks ago
For work I currently spent quite a bit of time in video conferences. I have an external webcam from work which gives a better image than the built-in webcam, but it regularly started giving problems in the image. Hickups or blinking images, suggesting some communications problem between the webcam and the computer.

Since the webcam, a Microsoft lifecam studio, is still being sold and advertised as works good with Windows 10 I thought it wasn't the age of the webcam or a problem with the drivers.

So I tried a different solution which is almost the standard solution of a radio amateur for interference problem: add more ferrite to the cables. The USB cable is thin which suggests to me there is not a lot of room for good shielding. Pulling the USB cable through a ferrite core twice right after the USB plug made the problems go away.

2020-11-03 New countries in amateur radio: Cuba and the Seychelles islands 3 weeks ago
For most Dutch amateurs the first countries they have HF contacts with outside Europe are in North and South America. For some reason my DX from home has a slant to the east, so a lot of the Americas is still on my 'wanted' list.

This weekend I was active on the remote radio which has a 10-12-15-17-20 meter band antenna and I heard a Cuban station on 15 meters phone. After a number of tries I had the contact so that was my first contact with a Cuban station.

I also heard a station from Vatican City (for radio this is a separate entity) making contacts but it had so many stations responding I did not get through even with trying for almost 20 minutes.

Update 2020-11-04: Another new country in the log: the Seychelles islands. A country name that I usually associate with bad corners of the Internet at work is now a positive development as I got S79KW in the log with a very marginal FT8 contact on the 20 meter band, but I saw his final '73' report so it should have been logged on the other side.

2020-10-26 I participated in the CQWW DX SSB Contest this weekend 1 month ago
This weekend was the CQWW DX SSB contest, which is one of the bigger contests on the amateur radio calendar. I had planned to participate, I made sure to get my contest software TLF completely configured and tested before the contest. But I didn't get around much to it most of Saturday. I only started Saturday evening to make some contacts on 40 meters which wasn't very successful from my home station.

Sunday afternoon things got a lot better when I tried the 20 meter and 10 meter amateur bands. Yes, 10 meter was open during the contest. This wasn't completely surprising as I made a number of 10 meter FT8 contacts earlier in the week.

The claimed results:
Band   160   80   40   20   15   10
QSO's    0    0    5   31    0   25

2020-10-10 The igate is igating 1 month ago
pi4raz igate running showing packet
pi4raz igate running showing packet
I dug into 'how to build code for the ESP32' and found Installing ESP32 Add-on in Arduino IDE (Windows, MacOS X, Linux) and since I have the Arduino IDE working enough for the previous project with a programmable microcontroller: the nanoKeyer morse keyer I did the steps to add ESP32 support.

I had to find the right settings for the specific ESP32 chip and since it is labeled "ESP-WROOM-32" I ended up at ESP-WROOM-32: Uploading a program with Arduino IDE and used the settings 'Board: FireBeetle-ESP32', 'Flash Frequency: 80 MHz', 'Upload Speed: 921600'.

The sourcefile to compile and upload to the ESP32 in the pi4raz igate is pa2rdk/APRS_IGate/APRS_IGate.ino.

I changed the definition of struct StoreStruct for a bigger wifi password (64 chars) and noticed that after uploading the updated code the last parts of the StoreStruct got mangled. I changed to #define EEPROM_SIZE 174 which seems to fix this.

I will admit to doing a bit of cargo-culting here: just following some google results and fiddling a bit until it works, with limited idea what I'm actually doing and what the effect of my changes is. The kind of weird results I got after growing the wifi password buffer suggested clearly to me that I was looking at some sort of buffer overflow, so I started looking for buffer sizes.

But the igate is now talking to the APRS network. First results visible at PE4KH-10 tracked on aprs.fi.

2020-10-10 Meer opties in de Draytek Vigor 130 gevonden, maar impulse noise protection inschakelen lukt niet 1 month ago
Vandaag actief met de radio met 40 meter en 20 meter morse en FT8, en heel regelmatig valt de VDSL link uit en moet opnieuw opgebouwd worden.

2020-10-06 Finished and tested the electronics of another project: the igate 1 month ago
After finishing the Raspberry Pi ntp server in the weekend I continued on a long-running project: the PI4RAZ igate I started working on in June (and ordered in September 2019). I dragged the soldering iron, the soldering mat and lots of parts downstairs to work on it on Sunday evening. Soldering lots of pins to an Arduino nano is hard work.

I finished the last soldering on Monday evening and had a long and hard look at all the connections and redid a few. I used a multimeter to make sure three really close soldering islands weren't connected, found two with 0 ohms between them in both polarities so I fixed that issue.

After that I took the plunge of actually powering up the print and it looks good. The display shows output and I can walk through the setup when I connect a usb cable to the ESP32 module.

I can't make it run yet: the space for the wifi password in the ESP32 module is only 25 characters which is not enough for our home network. So I will have to look into changing the code (it has an update anyway: Software update iGate - PI4RAZ) and find a working way to program an ESP32 from linux.

2020-09-29 I participated in the CQWW RTTY Contest 2020 1 month ago
RTTY Contest on websdr I was wondering until the last moment whether to do it or not but eventually I did participate in the CQWW RTTY Contest in the last weekend. Seeing other radio amateurs get ready on social media helped me decide and jump in.

I made 165 contacts on the 20 and 40 meter band. No new countries! I was seeing decodes from a station from Thailand but he did not decode my replies. It was also interesting to see how some stations that couldn't hear me at one time were almost easy to contact at other times. But not the one from Thailand, that one never came back.

I only worked search and pounce, looking for other stations available for contacts. Some stations had major pile-ups but coming back later helped.

Getting my log in a format that I could upload was a bit of an issue. I selected the CQWW-RTTY contest in the contest setup of fldigi, and it logged the CQ zone numbers and state in the right windows. But on the export to cabrillo there is no option to export those values. Workaround: select the right adif part of the log and use the CQ WW RTTY DX Contest ADIF to Cabrillo Convertor. I did have to fix my one US contact since the state wasn't exported correctly.

Update 2020-10-04: My raw score before log checking is 22579 points according to 2020 CQ WW RTTY Contest raw scores.

2020-09-16 My amateur radio activity versus the sunspot cycle 2 months ago
PD4KH start on HF bands versus the sunspot cycle
My start on the HF bands versus the sunspot cycle. Click for full graph with legend.
Recently the start of the new sunspot cycle is mentioned a lot in radio amateur news because the influence on ionospheric propagation is strong and the start of counted sunspot cycle 25 has started. Looking at the graphs I felt like I started just at the downward trend of the previous sunspot cycle.

So I looked it up at Solar Cycle Progression - NOAA / NWS Space Weather Prediction Center and zoomed in to the time when I made my first contacts making the screenshot in this article. And indeed, August / September 2014 was part of the last peaks of cycle 24, and it went mostly downhill from there. So my experience that I made my first HF contacts on 10 meter and soon had to go to lower frequencies to get any propagation matches those measurements.

2020-09-15 VDSL hikt als ik actief ben op de radio binnen het VDSL spectrum, maar ook er na 2 months ago
Dit weekend was ik weer eens behoorlijk actief met amateurradio en als ik ging zenden was dit eigenlijk iedere keer onder de 17 MHz, dus binnen het VDSL spectrum. Ik was actief net boven 14 MHz (20 meter band) en net boven 7 MHz (40 meter band). Iedere keer als ik naar een andere frequentie ging verbrak de VDSL de verbinding en moest die opnieuw opgebouwd worden, ook als ik binnen dezelfde band opschoof. Ook waren er in de nachten nadat ik actief geweest was nog onderbrekingen.

Dit keer ook opvallend: het 'geheugen' van de VDSL verbinding is veel korter. Een avond later kreeg ik weer een onderbreking als ik op dezelfde frequenties actief werd, ik was gewend dat dat bij meer dan een week was.

Al met al is de VDSL dus een stuk gevoeliger voor het soort storingen wat amateurradio veroorzaakt (korte storingen op wisselende frequenties). Ik dacht dat dat in DSL termen "impulse noise". Nu begrijp ik ook dat de firmware met 'optimized for KPN' modem driver die ik nu gebruik anders reageert op dit punt dan de versie die ik gebruikte voordat er problemen met rare verbroken verbindingen kwamen. Geen vooruitgang dus. Wanneer komt er glasvezel naar de huizen? Glasvezel veroorzaakt geen storing op radiofrequenties en het raakt niet verstoort van nabij radiogebruik.

2020-09-13 A weekend with some radio: first hand-paddled morse contact, a new country and data contacts 2 months ago
After lots of other things a weekend where I made time for amateur radio. I set up the endfed antenna and used a mast to raise the antenna at the end of the garden a bit, which hopefully increases the range a bit.

The big new thing was the last radio contact of the weekend: I decided to get on the air with the paddle as an exercise in morse. After looking for a contact at a reasonable speed where the exchange would be more than just callsigns and signal report I heard someone call CQ on the 40 meter band at about 20 words per minute. So to exercise my sending and not try to decode everything at 20 words per minute I cheated and used the computer to decode most of the morse code. I answered with my call and some basic information, with the printed CW QSO example in front of me. The other radio amateur had the patience to listen to my relatively slow speed (12 words per minute) and I had the contact. So I ended with a good - ..- which is morse for TU which is the abbreviation for "Thank You!"

Earlier in the weekend I made lots of FT8 and some FT4 contacts, just getting more calls in the log. I saw some for me new countries active. I managed to get French Guadeloupe as a new country in the log, and Saint Julia on a new band.

My notifications for the Bulgarian Saints showed me that LZ595IP was active in PSK31. I haven't used that mode in a while. I made the contact, so now I have that call in morse and PSK31, still looking for other modes.

2020-08-03 Trying a number of amateur satellite passes with a new radio and finally success 3 months ago
Saudisat 1c / SO-50 cube satellite
Saudisat 1c / SO-50
A few weeks ago I tried the Baofeng UV-5R on a satellite pass again to at least receive signal. It did receive something but kept closing the squelch during reception even at squelch level 0. This seems to be a common problem with this model radio.

I decided to put some money into a handheld radio that can do full-duplex. My original Wouxun seems to have developed serious issues receiving on the 2 meter side, but it has served me very well as a handheld radio over the years. So based on reviews about the Wouxun KG-UVD8D/KG-UVD9D models and how their full-duplex capabilities worked in combination with satellites I decided to buy one of these. The current model is the KG-UV9K which adds airband receive capability. I ordered one from bamiporto which came after a few days.

Based on the settings in AO-85 & Wouxun KG-UV9D - more testing I set mine up and tried a number of passes. The passes on satellites AO-91 (Fox-1B) and AO-92 (Fox-1D) all failed. The passes weren't too high and during busy weekends so there was a lot of competition for the uplink. With only 4 watts I am a bit limited there.

The difference between the Baofeng UV-5R and the Wouxun KG-UV9K in handling audio from satellites with the squelch full open is clear: with the Wouxun I only get an interruption when I let go of the transmit button.

Yesterday evening I tried a high SO-50 pass. A southwest to northeast pass, which gave me the option to stand in the front yard with radio, antenna and a smartphone with the W1ANT satellite tracker. I had trouble understanding some stations but could hear others fine who seemed to understand most stations fine, given the contacts I heard. In a gap I called F5ERS/P which turned into a good first contact and after that G0ABI called me and that was a good second contact.

2020-07-31 Letting the nanokeyer decode my morse attempts 3 months ago
I'm still trying to learn morse and I currently make too many errors while sending with the paddle at a reasonable speed (12 words per minute).

Digging into the documentation for the winkeyer protocol showed me the option to get the morse it thinks I sent back to the computer.

This is even a supported option in winkeydaemon, the -e option.
       -e     Turns  on  winkeyer's  'echo'  feature and makes the daemon echo
              transmitted CW to all active clients (see '-p').

              Test this feature with the  'netcat'  utility:  'echo  |  nc  -u
              127.0.0.1  6789'.  This creates an active, echo-only client ses‐
              sion.
And indeed I can test my work:
$ ./winkeydaemon -s 13 -e
$ echo | nc -u localhost 6789
CQ CQ DE PE4KH
This could be used to write a morse trainer program. For now I use it to test whether I paddle what I want.

2020-07-12 I participated in the IARU HF contest this weekend 4 months ago
Again this year one of the important radiocontests for me: the IARU HF contest was this weekend. I made both SSB and CW contacts on several bands.

I made 22 contacts in morse. I concentrated on SSB during the day, aiming to get some nice contacts in the log. There were good 10 and 15 meter openings which is always nice in a contest. I haven't done a lot of contesting on those bands so those enabled me to get more multipliers and a higher score.

In the end I made 159 contacts, with a claimed score of 343 qso points * 74 multipliers = 25382.

2020-06-29 Newish electronics project: an igate 5 months ago
Some time ago I saw announcements of an igate build project from PI4RAZ, the amateur radio club in Zoetermeer. An igate is a system that receives APRS messages and forwards them to the Internet aprs servers.

There is a distinct lack of APRS coverage here in Utrecht, so more places that receive those messages and pass them to the Internet are a good idea. A specialized repeater to repeat them on the air would be even better, but that needs a special radio license which is one step too far and expensive at the moment for me.

The electronics came in months ago, but time to pick up the soldering iron and start with the hard part wasn't available. I started this monday with that hard part: soldering a VHF module on top using something close to surface mounting. Just with a lot more space between the soldering islands than real surface mount. Still needed good light and a magnifying glass to check my work constantly. I only had to desolder one small blob of solder which went in the wrong direction.

After that I soldered the resistors. That went fine. After that my eyes were too tired, but the first step has been made.

2020-06-28 Future cycling goals (2) 5 months ago
As I mentioned before I have some future cycling goals which include some form of long-distance cycling journey, with serious influences from the book Computing Across America. Naturally amateur radio will play a part in such a cycling journey, just as Steven K. Roberts had on his trips.

Via the german amateur radio club DARC I found this bit in the "Deutschland-Rundspruch 24/2020":
DK3JB erreicht erstes Ziel auf seiner Funk-Fahrrad-Reise

Hans-Gerhard Maiwald, DK3JB, hat nach mühsamer und beschwerlicher Fahrt, teilweise auch wegen schlechter Radwege, am 15. Juni gegen 21 Uhr sein erstes Ziel, Kappel im Hochschwarzwald, erreicht. Dabei legte er ohne E-Unterstützung 580 km mit seinem 40 kg schweren Radanhänger zurück. Dem 72-jährigen OM geht es gesundheitlich gut. Hans-Gerhard gelang es, den weitaus größten Teil der Strecke permanent mit seinem TH-D74 in APRS aufzuzeichnen. Dabei hat sich der 1200 g schwere 12 V/20-Ah-Lithium-Ionen-Akku sehr bewährt. DK3JB hat zahlreiche Verbindungen in FM und D-Star vom Fahrrad aus getätigt. Durch Ludwigshafen wurde er von mehreren Funkamateuren gelotst und seine Route mitverfolgt. Hans-Gerhard bleibt bis Sonntag in Kappel und radelt danach vorerst an den Bodensee weiter.
And I found out more about the cycling tours between Siegen and Friedrichshafen in Germany via Funk-Fahrradtouren of DK3JB and it is very inspiring to me. There is also an article DK3JB wieder mit dem Fahrrad unterwegs nach Friedrichshafen - funkamateur.de with information about this tour in 2020 (all in German, which I can read but not really write). He has done this tour several years already, I found an article from the June 2008 trip: Mit Fahrrad, Zelft und FTM-10SE durch Süddeutschland (pdf).

After having read a book about cycling through Europe with the Rhine as one possible route, this confirms my earlier thoughts. Combining recumbent cycling, amateur radio and a nice ride through Europe is the direction I'm thinking.

2020-06-07 CQRLOG and repeater contacts 5 months ago
Friday evening I had a contact with PI4AA via the PI2NOS repeater. So I logged the contact with those parameters in CQRLOG.

After a number of other contacts I wanted to upload my new contacts to LoTW. In an upload, CQRLOG creates an ADIF file of the contacts and lets tqsl sign the resulting file before sending the signed file to LoTW. But tqsl doesn't want to include repeater contacts (those aren't valid for LoTW, so it interprets the rules correctly) and it gives a return status 9 meaning "some QSOs suppressed" which CQRLOG displays correctly. But as a result of that return code it doesn't allow for the other contacts to be uploaded at all, leaving me with a growing number of contacts not uploaded to LoTW.

I reported the bug to the CQRLOG forums: Propagation type RPT (repeater) should not be uploaded to LoTW - Forums » CQRLOG » CQRLOG - bugs with a suggestion for a program fix. From my experience, good bugreports for CQRLOG will be acted upon fast.

In the mean time as a workaround I mark all contacts with propagation type 'repeater' as already uploaded to LoTW to skip them. MySQL statement:
$ mysql -S /home/koos/.config/cqrlog/database/sock cqrlog002
mysql> update cqrlog_main set lotw_qslsdate=curdate() where prop_mode='RPT' AND lotw_qslsdate is NULL;
Query OK, 1 row affected (0.03 sec)
Rows matched: 1  Changed: 1  Warnings: 0
and now other contacts can be uploaded fine.

2020-06-03 I participated in the Dutch PACC 2020 in February 5 months ago
But I forgot to write about it, because I made a very minimal number of contacts: 6. I wanted to get the Veron A08 contest group using call PA0AA in the log and added some others. And on submitting the log I didn't set the category to 'checklog' so there is a result with a ranking.

I got reminded today because our friendly mail delivery person brought an envelope with the token of merit (het vaantje) which is very special for this contest.

The good part is all 6 contacts were valid, so 6 contacts, 6 points, 3 multipliers making a stunning score of 18, and not the last in my category! Ranking 117 (out of 122) in single operator all band low power ssb only.

2020-06-01 I participated in the CQ WPX CW contest 2020 5 months ago
After a number of recent morse contacts with special event stations I decided to participate in the CQ WPX CW contest during the weekend. Not for getting a big score, but to get experience with morse contesting.

Morse speeds in a contest like this are 25-30 words per minute which I can't decode, so I used fldigi to decode most of the morse. This means I have to enter my results as 'assisted'. And 'most' of the morse is the correct description because the important detail to decode are callsigns and serial numbers. The signal report is always 599 or 5NN which is usually sent faster than the rest of the conversation because it's a specific pattern a trained morse operator hears anyway.

I really didn't participate very long and still made 65 contacts. I'm not sure they all went correct, but it's a start. If I make 10 errors each of those is only 1 error for the other station. It's interesting how this approach to morse contesting gets me 65 contacts when serious participation in a digital mode contest will get me about 120 contacts.

But high numbers of contacts are quite normal in a morse contest. I have received serial numbers over 2000.

Logs are processed and the first confirmations via ARRL Logbook of the world are already coming in.
