        The ABEM WADI™ VLF instrument has been the standard all over the world for many years. Now there is a modern Windows™ graphical download and analysis for WADI data: RAMAG

       In geophysical VLF work, it is the magnetic component of the electromagnetic field from distant VLF (15-30 kHz) radio transmitters that is used. RAMAG stands for radiomagnetics and it is software designed for the planning of a VLF survey and for the interpretation of recorded geophysical VLF data.

        RAMAG transfers data from the Abem Wadi and transforms field data into line graphs of original or filtered data in either single profile or multi-profile format. Graphs can be scaled to any size supported by the currently installed printer, A current density cross section can also be produced in color or grey scale.

        All graphs, except the multi-profile plot, can be completely customized by using the interactive editing tools that are built into the software. Graph components such as text labels and fonts, X and Y axes, axis labels and ticks, line attributes (thickness, color, solid, dashed etc.), spline smoothing, and data point symbols are examples of features that can be edited and changed by the user while the graph is on screen.

         The linear filtering process used is based on the Karous and Hjelt algorithm published in 1983, This filtering algorithm has been combined with a weighted running average smoothing function.

        The Survey Planner has input boxes for entering the latitude, longitude and local time zone of the proposed survey site. The program then searches a database and produces a listing of all transmitters within 7000 km radius. For each transmitter found, the listing provides the distance in km, the bearing relative to true North, the effective transmitting range and the off~air schedule in local time.
