On January 13th a nice type II burst was observed by more than 15 stations of the e-Callisto network worldwide. Here some nice examples of the event. These plots can be used to improve instrumental quality or they can be used to derive the speed of the CME.
Signals of both antennas are first amplfied by ~20dB, then fed into a Wilkinson-power combiner. The combined signal is fed into an S-band down-converter (KUHNE-Elektronik Germany). The IF output of the converter is fed via a long 50 ohm coax into the observatory and to a Callisto spectrometer.
