I upload logs to eQSL.cc and ARRL Logbook of the World, during and after being active on the radio. I upload logs to www.qrz.com and clublog on a regular basis. I like paper cards via the QSL bureau so I send those out when requested or when I think the other party will appriciate one and I will respond when I receive a card. You can also request a card via the Log Search on clublog for PE4KH using the OQRS service. Notifying me via e-mail that you would like a card is also possible.
I appreciate SWL reports for QSOs and will respond.

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.
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.
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.
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.

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 PE4KHThis could be used to write a morse trainer program. For now I use it to test whether I paddle what I want.
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.
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.
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.
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: 0and now other contacts can be uploaded fine.
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.
