Raspberry Pi 5 with RTL-SDR v4 connected to "3D Printed UHF QFH Antenna by surligas" (See Satnogs wiki) with Minicircuits 400-510 bandpass filter on the front end before the pre-amp, Uptronics 440 Mhz CubeSat filtered pre-amp (427 - 450 Mhz with >=16dB gain) The QFH antenna's need about 15-20 degrees elevation. Pre-amp scripted in satnogs-config to switch on/off automatically. Currently, due to position of antenna, near overhead or westerly passes are best heard by this station.
