Near-Real-Time F2-Layer Critical Frequency Map
- This map can be used to determine the frequencies that will always be returned to the Earth. Transmitted frequencies higher than the indicated contours (which are given in MHz) may penetrate the ionosphere, resulting in lost power to space.
The map shows the radio auroral zones as green bands near the northern and southern poles.

Meter Mate - SWR Graph Software
- Meter Mate is a companion utility for your directional watt meter that allows you to calculate the SWR reading when the forward and reflected power readings are measured. In addition to calculating the antenna system SWR Meter Mate will also plot the SWR curves of all of your antennas onto graphs that may be printed out.
