Raspberry Pi 3b+ with RTL-SDR v4 connected to "3D Printed UHF QFH Antenna by surligas" (See Satnogs wiki) with Uptronics 440 CubeSat pre-amp and Minicircuits 400-510 bandpass filter. The QFH antenna's need about 15-20 degrees elevation. Updated RTL-SDR drivers for v4, pre-amp scripted to switch on/off automatically. Currently, due to position of antenna, near overhead or westerly passes are best heard by this station.
