Welcome to my channel. My name is Ralf and I have been a radio amateur since I was 14 years old. After passing the exam, I was assigned the amateur radio call sign “DH3KR”. It sounds cryptic when you read or hear it for the first time, but with the help of these letters and number combinations, radio amateurs worldwide recognize each other, and the call signs are usually registered to the person for life. I report on my interests, activities and hobbies and would be happy to take you along with me. If you are interested in technology, travel and the outdoors, then there might be something for you too. When I travel, my shortwave station is always on. Sometimes I also combine my bike trips with shortwave radio. I look forward to your comments, suggestions and questions. I would like to thank you for my contributions by subscribing to my channel and a 👍 - now let's go!
