SYNOPSIS
dcf77 [-a hw:0,0] [<options>]
-h --help
This help
--config [~/]<path to config file>
Give a config file to use. If it starts with '~/', path is at home dir. Each line in config file
is one option, '-' or '--' must not be given!
-v --verbose <level> | <level>,<category>[,<category>[,...]] | list
Use 'list' to get a list of all levels and categories. Verbose level: digit of debug level
(default = '3') Verbose level+category: level digit followed by one or more categories -> If no
category is specified, all categories are selected
-v --verbose date
Show date with debug output
-a --audio-device hw:<card>,<device>
Sound card and device number (default = '')
-s --samplerate <rate>
Sample rate of sound device (default = '192000')
-b --buffer <ms>
How many milliseconds are processed in advance (default = '50') A buffer below 10 ms requires low
interval like 0.1 ms.
-T --tx
Transmit time signal (default)
-R --rx
Receive time signal
-F --fake
Use given time stamp: <year> <month> <day> <hour> <min> <sec>. All values have to be numerical.
The year must have 4 digits.
--feierabend
--end-of-working-day
Use fake time stamp that equals 5 O'Clock PM.
--geburtstag
--birthday
Use fake time stamp that equals birth of the author.
-W --weather <weather> <extreme> <rain> <wind dir> <wind bft> <temperature>
Send these weather info for all regions / all days. See -L for infos on values. weather = 1..15
for common day and night weather. weather = 1..15,1..15 for specific day and night weather.
extreme = 0..15 for extreme weather conditions. rain = 0..100 for rain/show probability. (closest
is used) wind dir = N | NE | E | SE | S | SW | W | NW | 0 for wind direction. wind bft = <bft>
for wind speed in bft. (closest is used) temerature = <celsius> for common min and max
temperature. temerature = <celsius>,<celsius> for specific min and max temperature.
--beach-party
Beach weather, equivalent to -W 1 0 0 0 2 35,20
--santa-claus
--muenster-2005
Deep snow, equivalent to -W 7 1 100 E 3 1,-1
-A --at-region <region> <advance minutes>
Alter time, so that the weather of the given region is transmitted. To allow the receiver to
sync, give time to advance in minutes.
-L --list
List all regions / weather values.
-C --city <name fragment>
Search for city (case insensitive) and display its region code.
-D --double-amplitude
Transmit with double amplitude by using differential stereo output.
--test-tone
Transmit a test tone (10% level, 1000 Hz) with the carrier.
-r --realtime <prio>
Set prio: 0 to disable, 99 for maximum (default = 0)
--fast-math
Use fast math approximation for slow CPU / ARM based systems.
Press 'w' key to toggle display of RX wave form. Press 'm' key to toggle display of measurement values.
