Input impedance of dvb-t’s tuner chip R820T = 75 ohms
Reason: The DVB-T USB is designed as TV Reciever, and TV’s defacto standard is 75 ohms.
For HAM Transmitter/Receivers, the defacto standard is 50 ohms.
As far as I know, the Flightfeeder, FR24 feeder, Kienetic Beast Receivers are all based on HAM standard and have 50 ohms impedance.
