 Amateur radio Glowbug enthusiasts can often be heard communicating on the shortwave bands via CW using Morse code.Many vintage radio clubs sponsor special events and contests, such as the "AM QSO Party" sponsored by the "Antique Wireless Association", the "Heavy Metal Rally" sponsored by "Electric Radio Magazine", and the "Classic Radio Exchange".Such operating events are not traditional ham radio contests inasmuch as they are a night of friendly QSO’s using home-built, restored commercial ham, broadcast or military equipment.
