📡 QSL Cards (Amateur Radio)

I still appreciate and actively use traditional paper QSL cards.

If you send me a paper QSL card, I will usually reply with a confirmation card via the same method.

I am a member of the Deutscher Amateur-Radio-Club (DARC), local chapter P24.

I especially appreciate QSL cards from fellow operators and from amateur radio enthusiasts who may have built or tested one of my projects.

🚫 Note: I do not respond to digital QSL systems (eQSL or similar services).

🧭 Note

I’m not a typical social media communicator, but I usually respond to messages when time allows.

🤝 Final Thoughts

Many things in the world of technology happen by chance, shared interests, or simple collaboration between like-minded people — everything else tends to fall into place naturally.
