The receiver 134 – 141 MHz in execution Professional is placed in a ”luxury” box made by BOPLA and it has moreover another electronic circuit for recognition of presence of the signal WEFAX 2400 Hz, which collaborates with the system of automatic search of current passage of the satellite NOAA and stopping of the mode SCAN at the current frequency in the band 134.00 MHz – 141.00 MHz.
Front panel contains control push-buttons for selection of working frequencies, working mode of the receiver and a switch for selection of antenna, from which the received signal will be processed.
Rear panel of the box contains two
antenna connectors for independent connection of signal from converter LNC1700
and signals from antenna Turnstile for polar satellites. Rear panel also
contains 2 connectors CINCH for connection of speaker and for cable from the
computer sound card. The fifth connector serves for connection of power supply
+ 12 V. The set comprises also power supply +12 volt / 500 mA. The
receiver in execution PROFESSIONAL is ready for reliable operation in
continuous mode on professional worksite.

The RX137141MHz receiver (old model) has already been produced since 1998 and I have been gradually implementing various improvements of its technical parameters. The most recent modification of the service properties of the receiver consists in a possibility to connect it to a PC via the USB interface.
was initiated by the interest of the WXtoIMG decoding program http://www.wxtoimg.com/hardware/
users. The WXtoIMG program has outstanding properties for decoding of the APT
signals and it enables a completely automated operation and optionally also an
automatic sending of the decoded image to the chosen web page. The WXtoIMG
program sends a special code into the receiver shortly before the rise of the
satellite to the horizon, which will trigger the setting of the receiver to
one of the following 10
present I have started the production of a new model of the RX134141MHz
receiver with an extended range that was inspired by the needs of users of the
converter 1700MHz made in Italy,
the output frequencies of which are 134.00 a 137.50 MHz. The new model of the
receiver embodies all good properties, which were confirmed during a
six-year-long practical use by numerous users in many countries.
