Morse code… a passion that never fades. No matter what life brings, it’s always there — steady and comforting. Today, you can see me working CW on my double-contact paddle, fully immersed in the rhythm of dots and dashes. A moment outside of time… just me, the key, and the signal travelling across the world. Morse never fails. It connects, it calms, it unites. And as long as my fingers dance on this paddle, this passion will live on. — 73 from HB9HBY ✨ #HamRadio #CW #MorseCode #HB9HBY #DoublePad
