The idea and design of the detector is from the book "Software Defined Radio Tranceiver" T41-EP by AC8GY and W8TEE
I adapted the design for use with Raspberry PI 4B. On the PCB there is a Tayloe mixer FST3253 / SN74CBT3252 and a Si5351 oscilator.
A SN74HC74 is used to devide the clock by 4 and deliver 90 degree phase shift.
The SoapyHifiBerry driver work with my SDR software SDRBERRY, I did not test it with other SDR software and all is an experiment.

SoapyHifiBerry will create config file HifiBerry.cfg Si5351 correction can be configured and audio adc/dac alsa device name set
[si5351]
correction = "50000"

[sound]
device = "snd_rpi_hifiberry_dacplusadcpro"

ToDo:
- phase correction (if necessary)
