Auto compensating doopler effect on satellites

Post by m_a_x » Thu Nov 30, 2017 9:00 am

Hi, i use SDR# and receive many satellite downlinks on 145.800-146.000 but i have problems to keep them tuned even using an external knob, expecially for CW beacons.
What is the solution to compensate automatically the doopler effect?
p.s. Sometimes i receive 137MHz satellites and have the same problem but the bandwidth of the signal gives much more tollerance.

You can interface SDR# with satellite tracking software like Orbitron. Tutorial here for NOAA https://www.rtl-sdr.com/rtl-sdr-tutoria ... te-images/, but it should be easy to adapt it for other satellites.
