FAQ

Why does it not show the station's strength ?

The tuner does not expose this information

Sometimes the Standby button does not work ?

This has been experienced with the C 425, manually powering it off and on seems te resolve the issue

RDS RT does not always work

The tuner does not seem to pass all the information all the time from the RDS decoder over the serial bus even though the tuner's display seems to show the correct text.

Standby toggling or changing the frequency will make the tuner send the RDS data once more.

NadSerial

This python package implements the serial handling required to communicate with NAD devices, this could be extended to include more NAD devices such as recievers and amplifiers which share the same protocol. However, more recent devices have switched to another serial protocol, which is not compatible with this package.
