MultiFAX MF-R1 Weather Satellite Receiver

This is a high quality, low cost VHF Weather Satellite Receiver for capturing images from NOAA and Meteor polar orbiting satellites as well as WEFAX images from GOES and MeteoSAT geostationary satellites when used with a 1691-137.5 MHz downconverter.

• BANDWIDTH: MultiFAX started with an off-the-shelf scanner and completely re-engineered the filtering to optimize the receiver for weather satellite image capture. This is NOT the usual "remove the ceramic filter and put in a capacitor" patch but a true custom designed set of filters for the purpose of receiving the polar and geostationary weather satellites.

• FINE TUNING FOR GOES: To accommodate frequency output variations of typical downconverters, fine tuning around the output frequency (normally 137.5 MHz) is a must for a GOES/Meteosat receiver. Because of its synthesized tuning in 5 KHz steps, the MF-R1 is ideal for use with a 1691-137.5 MHz downconverter for GOES and Meteosat images.

  ---

• PREAMP POWER: A switched 12 VDC output is provided at the antenna input for powering an antenna pre-amp with no extra wiring! A low noise pre-amp is recommended for most APT antenna setups and 12 volt output at the antenna jack is perfect for many antenna/preamp configurations.

  ---

• AUDIO OUTPUT: The audio stage has been redesigned to provide two independently adjustable output audio amplifiers: one for the built-in speaker and one for the demodulator input. No extra amplifiers required for most applications.

  ---

• PROGRAMMABLE TUNING: The MF-R1 has 90 user programmable frequency channels - perfect for automatic scanning or manual frequency selection.

• PRICE: Because of the significant savings provided by starting with an off-the-shelf scanner, we can offer this high quality receiver at an incredible price: $249 (plus $6 S&H in US). DON'T LET THE LOW PRICE FOOL YOU! This is a serious, high performance weather satellite receiver capable of capturing very high quality images. The MF-R1 is warranted against manufacturing defects in parts and workmanship for a period of 90 days. NOTE: Because of the significant redesign of this unit, many of the original manufacturer's specifications (tuning range, selectivity) have been altered. The MF-R1 has a useful tuning range of 137.00 MHz to 138.00 MHz only.
