# "For six minutes each half hour, from 10–16 and 40–46 minutes past each hour,
|
||
# one-minute frames are replaced by a special extended time frame. Rather than
|
||
# transmitting 35 bits of information in one minute, this transmits 7 bits
|
||
# (time of day and DST status only) over 6 minutes, giving 30 times as much
|

# energy per transmitted bit, a 14.8 dB improvement in the link budget compared
|

# to the standard one-minute time code." (wikipedia)
