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. dcf77(1)
