Chronology

1. First version V1_CD4066B (Fail)

Use as keys chip CD4066B. After assembly, it turned out that the key passband is small, see the picture \V1_CD4066B\pic. There is also a problem with impedance, a few Om units required, ~ 1 kOm (for two keys connected in series, and 500 Om for one). There were other errors as well.

2. Second version V2_FSUSB30(Success)

Use as keys chip FSUSB30.
