Conductivity is a stand alone program that receives measured field strength data as input and then it automatically fits the field values to a ground wave curve. The program therefore, provides an accurate way of handling AM station field strength readings to ultimately determine a derived ground conductivity in a given direction for a given station. The program has many uses including providing a quick and accurate way of determining real ground conductivity which may be less than the FCC's M3 ground conductivity curves and can therefore be used in increasing the stations radiated power in a given direction.
Conductivity was thoroughly beta tested by a group of AM consulting engineers who each had input to the final program's design.

The screen shown below is the input screen. Data can be input by keyboard or it can be loaded from CSV (comma delimited) files.
Conductivity can select a station from the FCC's AM database or the station's parameters can be entered from scratch.
Once the measured data is entered, Conductivity can produce a new antenna pattern based on the measured data.
Conductivity can handle multiple databases along each radial, for example the user may want to enter the DA and the omni single-tower measurements in separate database files. The program can provide the ratios between such databases.
The "conductivity" screen is shown above. Once the measure points have been entered, the program will automatically determine the conductivity breaks along the given radial. In the screen above, the 30 degree radial was examined and the inverse field was calculated.
The window above allows the user to easily select between measured radials to be graphed. The program users a complete (What you see, is what you get.) WYSIWYG interface with the graph . The user can create text boxes, text and arrows on the graph surface to provide easy to read legends.
The program's "Export" function will save the measured/finalized ground conductivity values to a "transmitter" file that can be directly loaded into V-Soft Communication's premier AM allocations and mapping program AM-Pro.
Conductivity is the ideal program for working with AM station measured field data. Call us for more information about this exciting new V-Soft Communications program. 800 743-3684.
