Tracking Weather Satellites
137.000 MHz
RTL-SDR
One of the
first antennas I built was a simple V-dipole to receive weather satellite data on
137.000 MHz, I was able to track and record the downlink of a Meteor-M N2
satellite. However, there was too much noise to demodulate the imagery from the
carrier, pehaps moving the SDR dongle away from the computer would solve this.
