The frequencies for the time signals are 4996, 9996 and 14996 kHz. There 
are three frequencies because the signal strength changes over the day 
because of ionospheric effects. The less strong signal most likely is 
caused by lower sun activity in the last years, causing lesser signal 
reflection in the higher atmosphere.
