Home Satellite TV Receivers

The APT-06 was especially designed to receive Polar Orbiter Weather Satellites in the VHF frequency range. It feeds the received image data into the sound input of a PC or laptop computer for further processing so that an automatically operating weather satellite image reception station can be set up. Besides automatic operation, the APT-06 also offers manual control capability, which is helpful especially during setup and for experiments. Furthermore the APT-06 package comprises the Windows software program APT-CONTROL, which can be operated in a separate window besides the image decoding program. It allows detailed frequency- and other remote control functions on the APT-06.

An exactly matched receiver IF bandwidth of +/- 16 kHz together with an extremely linear phase-locked-loop-demodulator guarantees the superior image quality and precise temperature calibration WRAASE / WeSaCom Systems are well known for.

Considering its outstanding receiving capabilities, the APT-06 offers a very high price/performance value..

Satellite frequency Doppler shift is precisely compensated by a special AFC-circuit, which is fully active already when the satellite comes up over the horizon. This eliminates noisy reception periods when the satellite is quickly approaching from long distance. In addition, an active filter circuit carefully matched to the satellite subcarrier frequency is implemented to reduce remaining noise components.

In the input rf amplifier high-quality Hi-Q-filters with silver plated and shielded helical coils provide a very high immunity against interference from strong signals in the close-by aviation and ham radio bands.

Due to the low noise figure (typical 1dB) of the built-in rf-amplifier an additional antenna amplifier normally is not necessary. However, when a long antenna feed must be used, an antenna preamplifier or an active antenna is advantageous because it compensates for the cable loss and thus increases the reception range. For active antennas, like our MX-137 or KX-137, the DC supply voltage (9V) can be added to the antenna socket by simply placing a jumper on the rear panel ("ANT-DC").

At any time signal quality can be monitored by the built-in switchable loudspeaker.
