[Add Feature] Support for ALS162 (ex TDF) French NTP signal on 162 kHz #24

Hi,

Do you think you can add ALS162 ex TDF French NTP signal on the 162kHz frequency? See wikipedia for more information.

Many thanks.

Best regards

That signal is phase encoded so would require some very different way how we create the signal (which for the other simulated systems is just amplitude modulated). Might require some digging in the data-sheets of the pre-scaler we're using in the Pi to see if there would be a programmatic way to influence the phase.

It could be interesting indeed, but how to test it ? Is there any commercial clock which support ALS162 ?
