Many thanks to SWLing Post contributor Alan, who shares this Radio World piece which explores the fascinating world of long-distance FM reception via sporadic-E (E-skip), including rare double-hop events: Double-Hop Dreams and the Mystery of Long-Distance FM

A great read for anyone interested in the world of VHF propagation!

Alan also shared these resources:

Australian Bureau of Meteorology – Propagation Modes: Learn about various propagation mechanisms, including transequatorial propagation.
HeyWhatsthat.com Path Profiler: Calculate great-circle paths, view terrain profiles, and check Fresnel zones. Ideal for evaluating DX paths and terrain obstructions.
FCC FM Query: Look up FM station data, including transmitter location, ERP, and HAAT—helpful for assessing potential reception range, even for low-power stations.

Thanks, Alan!

Who are these new players, and what exactly do they plan to transmit?

Many thanks to SWLing Post contributor, Alan, for his recent article in Radio World titled “The Modernization of Broadcast Radio.” In it, Alan argues that the proposed “AM Radio for Every Vehicle Act” in the U.S. should go beyond preserving legacy systems and instead embrace Digital Radio Mondiale (DRM) as the future of terrestrial broadcasting. Drawing comparisons with digital transitions in countries like Norway, Switzerland, India, and China, Alan highlights the potential to reduce transmission costs, increase coverage reliability, and enhance emergency communications — all while offering a path to modernize U.S. broadcasting infrastructure.
