I haven't done anything with NFC in ages. Almost three years ago I dug up my knowledge again and learned about UID changeable cards and before that the last real digging into RFID was 11 years ago: Interesting development with the magna carta rfid card.

Anyway, my interest is renewed due to several factors, with "just looking for something to learn about and enjoy the process" as main one. As a first step I dug up my trusty touchatag reader and the collection of RFID tokens/cards. The touchatag reader still doesn't see any of the collected ski passes so I guess those are for other frequencies.

The collection of RFID tokens includes a number of one-use public transport tickets. Those are based on Mifare Ultralight "MF0ICU1" according to NXP TagInfo. The little bit that annoys me is that NXP TagInfo manages to list the transport company and the transaction date/time while I can't find any listing of the fields in a Mifare Ultralight for transport use online on a first search. Later searches (see below) give a lot more!

So I have to do some digging myself. And maybe get a few more recent one-time-use public transport tickets to get an idea.

As the UBA PSK63 is the first radiocontest I participated in after the start of my HF career in 2015 I decided not to miss it this year and get some contacts going. My first article about the UBA PSK63 contest: Playing in a radio contest.

Last weekend was the 2022 edition of this contest and I participated on Saturday and Sunday. The bands didn't seem as full with PSK63 signals as I have seen them in other years. Most remarkably the PSK63 traffic seemed gone late Saturday evening. When I tried again Sunday end of the morning the traffic was back. Returned serial numbers suggested stations with more time and/or better reception could get enough contacts in the log.

In the end I made 74 contacts. I started on the 20 meter band on Saturday afternoon, switched to 40 meter after dark. Late in the evening I tried to make a few more contacts but saw only a few other stations on 40 meter. On Sunday I resumed in the 40 meter band and made a number of contacts there. In the last hour of the contest I switched back to 20 meter in the hope of finding a lot of new calls there but only one new call showed up, the rest was in the log already. So I squeezed out a last few contacts on 40 meter before the end of the contest. I may have switched back to 40 meters a bit too fast according to the rules of the contest, I'll see what happens.

Anyway, a good contest. I see a few things to improve in how I participate in digimode contests that aren't really huge: better timing, especially trying to get more contacts during daylight hours on higher bands.

Ik ben al heel lang bezig met morse leren, en de nieuwste ontwikkelingen zijn dat het niet gaat lukken om de 'CW not included' op het pasje van Agentschap Telecom wat me identificeert als gelicenseerd zendamateur om te laten zetten in een 'CW included'. Dat was even een zware tegenvaller, maar ik heb die energie omgezet in een artikel met onze ervaringen. Misschien dat het nog ergens tot gevolg heeft dat er toch een route komt om dit op te lossen.

En daarnaast is het wel leuk om te schrijven merk ik. Misschien moet ik over meer onderwerpen die me bezig houden schrijven.

De illustratie bij het artikel van de 'CW not included' en 'CW included' op de pasjes heb ik zelf gemaakt (samenstelling van foto's van pasjes), de illustratie met de certificaten heeft Frank van der Pol PE2A gemaakt.

Het artikel is verschenen op België-route voor “CW included” niet meer mogelijk - Veron A08 Centrum en ook in sociale media gedeeld: België-route voor “CW included” niet meer mogelijk @pi4utr. Ook op het zendamateur.com forum: Morse examen in België niet meer mogelijk. Daar is een antwoord gekomen dat de stap via het Belgisch instituut voor postdiensten en telecommunicatie (BIPT) overgeslagen kan worden, dus die route gaan we proberen.
