It all depends on what equipment is in service in space.<\/p>\n A typical ground station for contacting the ISS station includes a 2-meter FM transceiver and 25-100 watts of output power. A circularly polarized crossed-Yagi antenna capable of being pointed in both azimuth (North-South-East-West) and elevation (degrees above the horizon) is desirable.

Since then, amateurs from more than 22 different countries have launched over 70 satellites, exploring both digital and analog satellite technology. Many of the latest birds have been school experiments, training scientists and engineers. However, you don't need to be a rocket scientist to participate-- Some satellites operate FM and can actually be worked using a dual-band handheld transceiver.
