Hi, my name is Theo Bemelmans and this website is to tell you a little about my main interests.Hopefully you will find some of it fun and some of it informative.

I am licensed since 1984 (born in 1960) as ON4AEK and since 2006 we could achive a two by one callsign and now i use OT4A mainly use in cw.

Cw (fast) is my favorite mode and was almost my only mode for many years.

Modelling,building and of course using all my antennas and towers takes a lot of time of my hobby.

As profession i am a technical advisor in a technical school.
