fmrepeater -h<br />
<br />
Soundcard (oss) FM-Repeater with ctcss squelch, ctcss generator, filters,<br />
rogerbeep, beacon (wav file) and PTT (LPT, RS232, parport pins). Needs rx<br />
audio from 60Hz up (fsk out), same on tx if subtone needed.<br />
Use audio pipe from/to alsa, sdr ...<br />
<br />
-a <n> retry <n> times to open sound input (every 50ms)<br />
-B <s> <s> send wav every <s> if continous open else every <s><br />
-b <s> <s> <Hz> <level> rogerbeep <delay> <duration> <tone> <level><br />
-C <level> Clipp audio before lowpass (0..1)<br />
-d <filename> dtmf on and send to file or pipe<br />
-E <s> program exit after <s> squelch open (0)<br />
-e <s> program exit after <s> squelch close (0)<br />
-f <n> fill oss with quietness to repair underrun bug (0)<br />
-G <level> input gain before audio processing (1.0) (use with limiter)<br />
-H <Hz> highpass (filter out all subaudio band<br />
-h help<br />
-I <s> send wav every <s> if continous closed<br />
-L <Hz> lowpass (beware modulator from high audio frequencies<br />
-l <level> limit audio level<br />
-N notch out received subtone to tx<br />
-o <filename> oss devicename (/dev/dsp)<br />
-o <infilename>,<outfilename> /dev/stdin,outpipe (mknod outpipe p)<br />
or in/out-pipe from SDR, afskmodem -D or alsa interface<br />
-o <infilename>,- detect subtone, dtmf with no sound out<br />
-P <s> PTT hold time (1)<br />
-p <devname> <pttbit> pttport and bit to switch<br />
* /dev/ttyXX for serial<br />
* /dev/parport0 for parallel<br />
* gpio for kernel gpio-interface<br />
choose value for <pttbit>:<br />
* tty: 0=RTS, 1=DTR<br />
* parport: 0...7 / -0...-7 (inverted)<br />
-u close ptt-tty file between switch actions, may not work on USB tty<br />
-r <Hz> adcrate (22050) (8000..96000) (filters tested with 22050)<br />
-S <level> <level> sqelch threshold <open> <close> (0.3 0.5)<br />
more open: save stay close but needs exacter tone<br />
more close: stable open but longer noise tail<br />
-T <Hz> <level> tx subtone (67..254) (0.0..1.0) (0)<br />
-t <Hz> rx subtone (67..254) (88.5)<br />
-v Verbous<br />
-W <soundfile> <s> <level> play wav after <s> squelch close with <level> 0..1<br />
wav type pcm 8/16bit 1/2chan any sampelrate, best as -r<br />
