This breakout board contains two crystals (77.5kHz and 60.0kHz) which allow you to receive both DCF77 and MSF with the same hardware.
You can select the frequency with the BAND input pin. Additionally there is a LED which shows the pulses arriving which makes setting up of the device much easier.
The frequencies which are supported gives possibilities do receive both the DCF77 and the MSF time signals.
Additionally there is a LED which shows the pulses arriving from the time signal which makes localization much easier.
