NAME

SYNOPSIS

DESCRIPTION

It scans frequencies from start_freq to stop_freq with an optional increment of freq_step (default step is 100 kHz). All values must be entered as an integer in Hertz (cycles per second).

Note: rigswr assumes that start_freq is less than or equal to stop_freq. If it is greater, rigswr will exit without doing anything.

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 radio that can measure VSWR and a Hamlib backend that supports reading VSWR from the radio.

Keep in mind that Hamlib is BETA level software. While a lot of backend libraries lack complete radio support, the basic functions are usually well supported.

Please report bugs and provide feedback at the e-mail address given in the BUGS section below. Patches and code enhancements sent to the same address are welcome.

OPTIONS

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 connected to the radio.

Often a serial port, but could be a USB to serial adapter. Typically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc. on Linux, COM1, COM2, etc. on MS Windows. The BSD flavors and Mac OS/X have their own designations. See your system's documentation.

-s, --serial-speed=baud

Set radio serial speed to baud rate.

Uses maximum serial speed from radio backend capabilities as the default.

-c, --civaddr=id

Use id as the CI-V address to communicate with the radio.

Only useful for Icom and some Ten-Tec radios.

Note: The id is in decimal notation, unless prefixed by 0x, in which case it is hexadecimal.

-C, --set-conf=parm=val[,parm=val]

Set radio configuration parameter(s), e.g. stop_bits=2.

Use the -L option of rigctl for a list of configuration parameters for a given model number.

-p, --ptt-file=device

Use device as the file name of the Push-To-Talk port using a device file as with the -r option above.

This is only needed if the radio doesn't have CAT PTT control and requires a separate device port to key the transmitter.

-P, --ptt-type=type

Use type of Push-To-Talk device.

Supported types are RIG (CAT), DTR, RTS, PARALLEL, NONE.

-v, --verbose

Set verbose mode, cumulative (see DIAGNOSTICS below).

-h, --help

Show a 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.

DIAGNOSTICS

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

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.

EXAMPLE

$ rigswr -m 2009 -r /dev/ttyS1 14000000 14200000 50000 > cswr

After completion, cswr contains the following lines:

14000000 1.50
14050000 1.31
14100000 1.22
14150000 1.07
14200000 1.07

The result can be plotted with gnuplot(1):

$ gnuplot
set data style linespoints
set grid
plot cswr
