NAME

       rigsmtr - measure S-Meter vs azimuth using Hamlib

SYNOPSIS

       rigsmtr [OPTION]... [time_step]

DESCRIPTION

       rigsmtr uses Hamlib to control a rig to measure S-Meter vs azimuth:
       It rotates the antenna from minimum azimuth to maximum azimuth.	Every second or time_step if specified in seconds, it retrieves the signal
       strength.
       Azimuth in degree and corresponding S-Meter level in dB relative to S9 are then printed on stdout.
       To work correctly, rigsmtr needs a rig that could measure S-Meter and a Hamlib backend that is able to get it, mounted  on  a  Hamlib  sup-
       ported rotator.

       Keep in mind that Hamlib is still BETA level software.  A lof of stuff hasn't been tested thoroughly, and the API may change without publi-
       cised notice. Please report bugs and feedback at the e-mail address given in the REPORTING BUGS section.

OPTIONS

       This program follow the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is  included
       below.

       -m, --model=id
	      Select radio model number. See model list provided by rigctl.

       -r, --rig-file=device
	      Use device as the file name of the radio to operate on.

       -s, --serial-speed=baud
	      Set radio serial speed to baud rate. Uses maximal rig speed as default.

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

       -C, --set-conf=parm=val[,parm=val]*
	      Set radio config parameter. See -L option of rigctl for a list.

       -M, --rot-model=id
	      Select radio model number. See model list provided by rotctl.

       -R, --rot-file=device
	      Use device as the file name of the rotator to operate on.

       -S, --rot-serial-speed=baud
	      Set rotator serial speed to baud rate. Uses maximal speed as default.

       -N, --rot-set-conf=parm=val[,parm=val]*
	      Set rotator config parameter. See -L option of rotctl for a list.

       -v, --verbose
	      Set verbose mode, cumulative (BUG, ERR, WARN, VERBOSE, TRACE).

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

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

RETURN VALUE

       rigsmtr exits with: 0 if all operations went fine; 1 if there was an invalid command line option or arg; 2 if an error was returned by Ham-
       lib; 3 if the rig doesn't have the required capabilities.

EXAMPLE

       rigsmtr -m 209 -r /dev/ttyS1 -M 202 > csmtr

       Collect S-Meter readings on a TS850 while an EasycommII rotator makes a full 360o, and record measurements in file csmtr.
       After completion, csmtr file contains for example the following lines :
	 0 -47
	 30 -40
	 60 -22
	 90 -3
	 120 10
	 150 1
	 180 -11
	 210 -24
	 240 -35
	 270 -42
	 300 -48
	 330 -51
	 360 -49

       Result could then be ploted with gnuplot:
	      gnuplot
	      set angles degrees
	      set polar
	      set grid polar 15.
	      unset border
	      unset param
	      set style data line
	      set rrange [-60:60]
	      set xrange [-60:60]
	      set yrange [-60:60]
	      plot "csmtr"
