1) How did you get involved in Ham-radio and how many years are being a ham now? 
My first encounter with Ham-radio was at an exhibition where the "Jonge Onderzoekers" ("Young Investigators") had a stand. This must have been in 1970 or so. It also included ham radio. Jaap, PA0OOS, was the operator. I was completely impressed by the equipment and the fact that you could talk wireless with others far away. After a year or so I became a member of VERON and PA0LPN and others helped me to learn the theory while I got CW lessons in a club course by Charles, PA0TY. At the end of the course I could copy 18wpm.
I passed my ham exams in 1973 at the age of 17. In those days you were not allowed to have a license before the age of 18. So, after a full year of waiting I finally became active as PA0ERA (1974). In 1998 I changed my call in PA5EA and in 2003 again to PF5X. From Oct 2004 to June 2006 I was active as 9V1CW in Singapore.
2) What attracted you the most in being a Ham-radio operator? 
Being able to make worldwide contacts on shortwave with the power of a light bulb.
3) What is your favorite mode and/or band? 
30m/CW, 6m.
4) What equipment do you use?
FT-1000MP, IC-736 (for 6m), 3ele SteppIR (20-6m), Rotary dipole for 30/40m, Inv. vee for 80m, Inv. L for 160m.
Micro-KEYER and Begali Signature paddle.
N1MM and DX4WIN logging software
5) Do you hold DXCC and what is the score?
DXCC Mixed Honor Roll (328, meanwhile 332 cfmd)
6) What has been your most memorable story related to Ham-radio so far?
27-Mar-2000. Checking OH2AQ at work, I saw that KH7R was reported on 6m in the South of Germany (around 0900utc I guess), longpath. After a while the spots gradually "moved North". I called Willem, PA0HIP. He was just awake and was not yet aware of this. He quickly called me back after 20 mins or so stating that he could hear him. After 15mins he called again yelling through the phone that I should go home immediately because he just worked him and he was LOUD .... So, I quickly decided whether driving home (approx. 15mins) would be short enough to take advantage of this unique opening which undoubtedly would be short. After 1 sec of thinking I ran to my car on the carpark and drove home. I was lucky there was no police who saw me nor any radar camera as I would have lost my driving license for sure (120km/h in the 50km/h zone is not entirely save ...). After 10 mins I arrived at home, rushed to the shack, switched on the rig and turned the beam SSE and.... noise over the entire band ! AAARGH ! I quickly called Willem, who shouted "140 and QSX 5 up". Tuning to that frequency he just came out of the noise. I shouted blindly my call on 50.145  (I am sure the whole street could have heard this) and to my complete excitement he came back to me. We quickly exchanged reports and the QSO was in the log at 11.08utc! Wow, KH6 on 6m long path !!! My heartbeat must have been close to 200. The nice thing was that I personally knew Ken. I had met him while preparing for N9NS/KH5K on Hawaii in 1993.
7) Do you think CW had it's best time since you don't need it anymore to get a license.
The best is yet to come .... ! CW ruled, rules and will always rule. Get on 6 or 160 and you will discover why (provide you want to work some real DX).
8) How would you explain our hobby to someone not familiar with Ham-radio? 
A many faceted hobby concerning communication and transmitting/receiving techniques and operating practice. Using shortwave radio waves which reflect against the ionosphere so that you can make long distance contacts. But also experiments at radar waves are possible, contact using satellites and reflection against the moon. It is always about experimenting and challenging yourself to get the most out of relatively simple equipment and antennas using standard or abnormal/sporadic propagation modes.
9) Do you have other hobby's besides Ham-radio?
I play tennis, golf, listen to jazz music, scaffolding in the house and enjoy family life.
10) Any final words to the people reading the interviews?
Like any other hobby, you have to be a little crazy to do this.
