Calibration KerberosSDR

These switches use PE4259 SPDT High Power UltraCMOS ®10 MHz–3.0 GHz RF Switch. Each switch uses a 3.3V control signal from GPIO  LED-s noise source KerberosSDR to select between antenna port 1 or an internal 50 ohm load. This set is intended to be used to automate the Kerberos SDR calibration procedure. It eliminates the need to manually disconnect the antennas for the calibration process.
