HamSCIence Telecon - Rob Suggs NN4NT Meteor Scatter - 13 November 2025

This week, HamSCI presents one of the leading authorities on meteor scatter, providing context to our upcoming Meteor Scatter QSO Party event (12-13 Dec.). Our speaker will be Dr. Rob Suggs NN4NT. He has been a ham for over 25 years and, simply put, he enjoys hearing meteor pings! He is a semi-retired, prominent NASA astronomer at the Marshall Space Flight Center in Huntsville, Alabama. For many years, he ran the Meteoroid Engineering Office, working to protect astronauts and the ISS from potentially catastrophic punctures. Rob is actively involved in the amateur radio community and is known for his expertise in topics such as planetary atmospheres, meteor scatter communication and the Apollo communication system. Suggs specializes in meteors, their sources, and how they can be used for radio communication. He has given presentations at events like the Huntsville Hamfest and the GNU Radio Conference, on topics including the Apollo communication system and general HF propagation science. He will describe the science background for meteor scatter communications including the sources of sporadic and shower meteors, the scattered signal characteristics and frequency dependence, and the vagaries of the scattering geometry as part of the continuing HamSCI speaker series. A brief introduction to the WSJT-X software and its MSK144 mode will also be given. The program was recorded on Thursday, November 13th at 4PM Eastern (2100 UTC).
