Automatic calibration KerberosSDR

Post by UB9MAS » Thu Apr 15, 2021 5:12 am

Hi everyone!
I present my version of implementation of automatic calibration of receiving channels.
Switching to a load of 50 ohms occurs when the noise source is turned on. Doesn't require scripts or anything. Only solder three wires to large PAD-s.

Very nice! Have you managed to confirm DFing after adding those switches? No phase distortion?
