rigsmtr — measure S-Meter vs azimuth using Hamlib
rigsmtr [OPTION]... [time_step]
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 publicised notice. Please report bugs and feedback at the e-mail address given in the Reporting Bugs section.
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.
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 Hamlib; 3 if the rig doesn't have the required capabilities.
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 :
- Result could then be ploted with gnuplot:
set angles degrees
set grid polar 15.
set style data line
set rrange [-60:60]
set xrange [-60:60]
set yrange [-60:60]
