A typical ARISS ground 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 (N-S-E-W) and elevation (degrees above the
horizon) is desirable. But successful contacts have even been made with
verticals and ground plane antennas. Commercial and public domain software is
available to help track when a shuttle or the ISS will be in range of your
station, and where to point your antenna.
To work ISS from your home, you should have at least the following Amateur
Radio equipment. A 2-meter radio with an output rating of 5 watts or more.
While it's possible to operate with an omni-directional antenna and even a
whip, a small beam antenna similar to the Arrow antenna works much better and
will increase your chances of success. If you plan to operate in packet mode a
standard 1200 baud AX.25 TNC should be used and connected to a computer running
APRS or other packet communications software.
