Amateur radio is not just about frequencies, antennas, propagation, equipment, or technical performance. Beyond all these, there is a deeply human side—perhaps the most valuable of all: friendship. Those sincere connections born on the air, between people who may never meet face to face, yet come to know, respect, and truly appreciate one another.
For me, YO2BTW, and for my wife Felis – YO2MGI, amateur radio means exactly this: people, emotions, the joy of communication, and the creation of international friendships—without barriers, without prejudice, without borders.
QSOs That Stay in the Heart
Over time, we have had many beautiful QSOs, but every now and then, a truly special one comes along. Recently, we experienced such a memorable QSO with Ulli – DF3SM. It was the kind of contact that goes far beyond the exchange of signal reports and technical details. We talked about our shared passion for radio, about life, about nature, and about the joy of being radio amateurs.
As always, Felis – YO2MGI was right beside me. We share the same vision of amateur radio and the same emotion when we feel that, somewhere far away, another radio amateur is on the same wavelength as us—both literally and figuratively.
More Than Just a QSL in the Mailbox
Some time after this QSO, a moment came that deeply moved us. The QSL cards arrived by post. The joy of receiving a physical confirmation of a QSO is well known to every radio amateur. But this time, the surprise was much greater.
Along with the QSL cards, there was also a beautiful handwritten letter, written straight from the heart. In it, Ulli (DF3SM) spoke about friendship, about the joy of sharing emotions, and about how meaningful these radio-born connections truly are. Every line conveyed sincerity, respect, and an authentic passion for this unique world of amateur radio.
Perhaps for those who have grown up in the age of modern technology, a letter may not seem like much. But when you read someone’s personal testimony about their way of life, written on a simple sheet of paper, folded to fit an envelope bearing both your address and the sender’s, you experience a LIVE, ORGANIC connection to this wonderful form of human communication: the letter.
The one we received from Ulli stopped us in our daily routine and made us smile deeply. We were truly happy. Such gestures remind you why you chose this hobby, why you love it so much, and how important it is to preserve the beautiful traditions of classic written communication—with postage stamps, postmarks, and the subtle “scent” of the distances traveled.
Classic QSL Cards in the Digital Era
We live in a time when digital confirmations through LoTW, eQSL, and other online platforms have become fast and extremely practical. We use them and appreciate them. However, classic printed QSL cards sent by mail hold a special value. They are not just confirmations of a QSO, but physical memories—objects that carry a story.
A traditional QSL card can be held in your hand, revisited years later, placed in an album or displayed on a wall. And when it is accompanied by a few heartfelt handwritten lines, it becomes something far more meaningful than a simple “confirmed.” It becomes a tangible human connection that stands the test of time.
Amateur Radio as We Love It
For us, amateur radio is not about “how many QSOs we’ve made,” “how many countries we’ve worked,” or “what ranking we’re in.” These things matter too, but they are not our priority. For us, it is about people—about friendships built over time, about the emotion of every contact, and about mutual respect among radio amateurs, regardless of call sign or country.
It is about turning on the station with joy, listening carefully, speaking calmly and with passion. It is about knowing that, somewhere in the world, someone answers you not only with a radio signal, but with a part of their soul.
Friendships Without Borders
Amateur radio has this unique gift: it brings together people from all corners of the world. It builds bridges between cultures, languages, and different ways of thinking. It creates friendships that can last a lifetime. A simple call on the air can become the beginning of a sincere relationship, based on respect, shared passion, and the joy of communication.
This is the side of amateur radio that we love the most—me, Adrian (YO2BTW), and Felis (YO2MGI). And it is the side we wish to promote and share further.
A Final Thought
Thank you, Ulli – DF3SM, for this special QSO, for the QSL cards, and especially for the letter that went straight to our hearts. Moments like these give true meaning to this wonderful hobby and motivate us to move forward, to be better, and to remain open-hearted.
Amateur radio is, at its core, about friendship on the air. And when that friendship also arrives in your mailbox, in the form of a letter written from the heart, you know you are part of something truly special.
73′ and best friendships to all,
Adrian – YO2BTW & Felis – YO2MGI


Dear Adrian,
what you wrote in “Friendship on the Air” is the best and most emotional definition of our common hobby that I have ever read! Thank you so much!!! I was really glad to meet you and Felis and I hope we will have many more QSOs in the future! 73, Ulli DF3SM
