MARCO Grand Rounds on the Air is a on-the-air 20m net, currently held on Sundays at 11am Eastern USA, with discussion of medical topics of interest to professionals, paraprofessionals, and patients. Discussion is led by a Net Control Station who works to overcome the vagaries of propagation and often requests relays. Livestreams by SDR are available at www.marcoaudio.net for those who cannot hear the transmitting station, a nice adjunct to make sure as many 20m participants as possible are heard. Be sure to look for blog posts about upcoming nets that will have Zoom simulcasts, and the sign-in info.
