From 
"...VF technology has become for me the HORSE that determines where I will go. And you can believe me that I have had a good ride in my life so far. There were times when I worked on the railway as a train driver and even on those machines I used to have a radio. On the roof of the locomotive there was an antenna for VKV a již se vesele vysílalo jako “Lokomobil”.“, takto charakterizoval svoj vzťah ku HAM Karel OK1DNH.
He certainly helped many radio amateurs in repairing equipment or building converters, which he also did professionally in his company AMA-CB Service. Unfortunately, Karl's short earthly journey has come to an end... Please give him a silent memory.
