We Meet on the Air to Share

The MARCO organization is open to all licensed amateur radio operators who are healthcare professionals, work in a related field, or are interested in health related topics.  MARCO conducts a weekly Grand Rounds on the Air (20m) net to discuss health related or ham radio topics and stream the audio online at www.marcoaudio.net.  Zoom simulcasts are often used to allow members without HF equipment to participate.

YouTube videos are made from these Zoom sessions, produced for the public, located at
