RDMW 2022 Launched!
North American broadcast mapping tool & database
We are proud to announce the launch of the latest edition of RDMW-2022. Now in its 9th year, RDMW comes with many new features and updated station data ready for 2022.
Radio Data Medium Wave (RDMW) allows you to see and map the coverage area of all medium wave (AM/MW) broadcast stations in North America including the USA and Canada.
If you’ve ever wondered why a radio listener would be interested in the coverage patterns or maps of radio stations then you can find out more here.
New developments for 2022 include:
- The latest callsign and technical data for all US and Canadian MW stations
- Expansion to cover Mexico, Bahamas and the Caribbean for the first time
- Expansion to cover 490kHz – 1700kHz; now includes MW Navtex stations
- Addition of real-time night/day terminator (greyline)
- “Click+Save” setting of your receiver location
- Easy tuning control added to control bar
- Easy daypart selector added to control bar
- Ray tracing control added on a per station basis.
- In-screen “Help” button
Knowledge drawn from RDMW has been fundamental in helping DXers further their craft and enjoy their hobby. It can help you plan your listening and help you target stations broadcasting from particular areas. Intelligence displayed by RDMW has helped European DXers plan and hear US stations over great distances – including so-called “daytimer DX” and transpolar propagation. The RDMW maps will also help you determine which stations you might hear on a particular channel, and which might be rather more elusive.
Drawing on the latest data from official sources, club sources and topped off with many days of extensive data checking and validation RDMW probably has the most comprehensive and up to date dataset for AM/MW broadcasting stations in North America. This data is combined with complex geophysical data and propagation modelling to provide you with extremely detailed coverage maps for both daytime groundwave and nighttime skywave coverage for around 5000 radio stations.
RDMW 2022 has been developed and tested by Bill Scott and Steve Whitt and is exclusively available from the Medium Wave Circle.
