PROGRAM:
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').
NB: rigswr (or third party software) will use rig model 1901 when using rpc.rigd.
-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.
