Receiver Control Window (Top Right). Each receiver has a customized control window. Features include instant recall of recently used frequencies, priority scanning and signal display. Clicking on "Find" looks up the frequency in the database. ERGO can profile a block of frequencies, do frequency-to-frequency scanning, and manage receiver memories.
Map Window (Lower Right). ERGO provides a traditional Mercator projection, as well as a customized Azimuthal-Equidistant projection centered on your location. The maps display the signal path, terminator/grayline, sun location, and auroral ovals (optional, to assist evaluation of polar paths).
Propagation Window (Lower Left). Propagation is evaluated between the transmitting and receiving locations and displayed as either MUF/LUF, Signal Strength or Signal-to-Noise graphs. You can use the Map and Propagation Windows in real-time with the currently tuned station, or in Forecast Mode to evaluate conditions for any level of solar/geomagnetic activity on any date and time. Notice the peak in signal strength associated with grayline conditions at sunset in Western Canada. Ergo runs on Windows 95, 98, ME, NT4.0, 2000 and XP. The minimum recommended system is a Pentium with 1024 by 768 video. PC cable and CT-17 are also required [not supplied]. [Click here to view a full size screen].
