A great day to celebrate the Intl. Amateur Radio centenary in Paris. Welcoming messages from the Doreen Bogdan-Martin CEPT and Comisión Interamericana de Telecomunicaciones. The Doreen Bogdan-Martin presented IARU with an original copy of the 1927 Radio Regulations that first defined the amateur service and allocated 80,40,20,10 and 5 meters

April 27 marks #MorseCodeDay, honoring the birthday of Samuel Morse, the inventor of Morse code. Though now considered primitive, this groundbreaking technology paved the way for innovations like the telephone, radio, microwave communication, computers, and even space satellites.

🚀 Open source is awesome! Just one day after open-sourcing the LiteX WR NIC for SPEC-A7, we’ve got a PR from Mimil25 adding the missing piece for the LiteX Acorn Baseboard Mini: White Rabbit support without the specific VCXOs! 🎉 This will also unlock WR support on the LiteX

It's important that the amateur radio community reports interference to their local amateur radio organizations and authorities!
