RIGSMTR(1) RIGSMTR(1)
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 supported
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 360°, 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"
