NAME

       rigswr - measure VSWR vs frequency using Hamlib.

SYNOPSIS

       rigswr [OPTION]... start_freq stop_freq [freq_step]

DESCRIPTION

       rigswr uses Hamlib to control a rig to measure VSWR vs frequency:
       It  scans  frequencies  from  start_freq  to  stop_freq  with a step of freq_step. For each frequency, it
       transmits at 25% of total POWER during 0.5 second in CW mode and reads VSWR.

       Frequency and the corresponding VSWR are then printed on stdout.

       To work correctly, rigswr needs a rig that can measure VSWR and a Hamlib backend  that  supports  reading
       VSWR from the rig.

       Keep  in  mind  that  Hamlib  is BETA level software.  While a lot of backend libraries lack complete rig
       support, the basic functions are usually well supported.  The API may change without  publicized  notice,
       while an advancement of the minor version (e.g. 1.1.x to 1.2.x) indicates such a change.

       Please  report  bugs  and  provide  feedback  at  the e-mail address given in the REPORTING BUGS section.
       Patches and code enhancements are also welcome.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').

       Here is a summary of the supported options:

       -m, --model=id
              Select radio model number. See model list (use 'rigctl -l').

       -r, --rig-file=device
              Use device as the file name of the port the radio is connected.  Often a serial port, but could be
              a USB to serial adapter.  Typically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc.

       -s, --serial-speed=baud
              Set serial speed to baud rate. Uses maximum serial speed from  rig  backend  capabilities  as  the
              default.

       -c, --civaddr=id
              Use id as the CI-V address to communicate with the rig. Only useful for Icom rigs.
              NB: the id is in decimal notation, unless prefixed by 0x, in which case it is hexadecimal.

       -p, --ptt-file=device
              Use device as the file name of the Push-To-Talk device using a device file as described above.
              This is only needed if the radio doesn't have legacy PTT control.

       -p, --ptt-type=type
              Use type of Push-To-Talk device.  Supported types are RIG, DTR, RTS, PARALLEL, NONE.
              This is only needed if the radio doesn't have legacy PTT control.

       -C, --set-conf=parm=val[,parm=val]*
              Set config parameter.  e.g. stop_bits=2
              Use -L option of rigctl for a list.

       -v, --verbose
              Set verbose mode, cumulative (see DIAGNOSTICS below).

       -h, --help
              Show summary of these options and exit.

       -V, --version
              Show version of rigswr and exit.

       NOTE!  Some  options  may  not  be implemented by a given backend and will return an error.  This is most
       likely to occur with the --set-conf option.

EXAMPLE

       rigswr -m 209 -r /dev/ttyS1 14000000 14290000 50000 > cswr

       Scans frequencies between 14.000 MHz and 14.200 MHz with 50  kHz  step  on  a  TS-850  and  records  VSWR
       measurements in file cswr.

       After completion, cswr file contains the following lines:
         14000000 1.50
         14050000 1.31
         14100000 1.22
         14150000 1.07
         14200000 1.07

       Result could then be plotted with gnuplot:
              gnuplot
              set data style linespoints
              set grid
              plot "cswr"

DIAGNOSTICS

       The  -v, --version option allows different levels of diagnostics to be output to stderr and correspond to
       -v for BUG, -vv for ERR, -vvv for WARN, -vvvv for VERBOSE, or -vvvvv for TRACE.

       A given verbose level is useful for providing needed debugging information to the  email  address  below.
       For  example,  TRACE  output  shows  all  of the values sent to and received from the radio which is very
       useful for radio backend library development and may be requested by the developers.

EXIT STATUS

       rigswr exits with:
       0 if all operations completed normally;
       1 if there was an invalid command line option or argument;
       2 if an error was returned by Hamlib;
       3 if the rig doesn't have the required capabilities.

BUGS

       Depending on keyer/QSK setup, transmissions in CW mode may not be modulated thus possibly giving a  wrong
       result. Please report this situation if it happens.

REPORTING BUGS

       Report bugs to <hamlib-developer@lists.sourceforge.net>.
       We are already aware of the bug in the previous section :-)
