To
receive APT (Automatic Picture Transmission) pictures from polar
orbiting satellites is easy. Normally in a 24 hours period four passes
from each of the NOAA satellites are available. Presently NOAA 12 and
NOAA 15 are transmitting on 137.500 MHz and NOAA 17 frequency is 137.620
MHz. A simple crossed dipole will give good results. It is recommended
to use a pre-amplifier between the antenna and receiver to increase
sensitivity so that low passes can also be received. A good quality
coaxial cable should be used from the pre-amplifier to the receiver.
