This week, my two satellite tracking stations achieved major milestones. Both has been operational for 4 years. The SatNOGS station receives telemetry on the 2-meter and 70 cm bands using a Raspberry Pi 3B with a RTL-SDR. Its dashboard can be found at https://network.satnogs.org/stations/1561/ The TinyGS station receives telemetry from satellites also in the 70 cm band but using the LoRa radio modulation technique. My station uses the Heltec WiFi LoRa 32 V2 single board computer containing a ESP32 CPU, LoRa radio and display. Its dashboard can be found at https://tinygs.com/station/KK6NOWPD@1236606575
