In the version 22.1 of the DRM-Log Plotter the Maidenhead Grid Locator can be written to "My Locations" in the DRM-Log Plotter. Goto SetUp / Receiver Coordinates / Change which opens the My Locations window. Write the Maidenhead Grid Square Locator in the "Add Location" field. The locator should be of the format "AB12cd". Press the "Convert" button and the Latitude / Longitude coordinates will be added automatically. This way you will get the actual distance and azimuth to the transmitter site.
