6 rigswr - measure VSWR vs frequency using Hamlib.
7
9 rigswr [OPTION]... start_freq stop_freq [freq_step]
10
12 rigswr uses Hamlib to control a rig to measure VSWR vs frequency:
13 It scans frequencies from start_freq to stop_freq with a step of
14 freq_step. For each frequency, it transmits at 25% of total POWER dur‐
15 ing 0.5 second in CW mode and reads VSWR.
16
17 Frequency and the corresponding VSWR are then printed on stdout.
18
19 To work correctly, rigswr needs a rig that can measure VSWR and a Ham‐
20 lib backend that supports reading VSWR from the rig.
21
22 Keep in mind that Hamlib is BETA level software. While a lot of back‐
23 end libraries lack complete rig support, the basic functions are usu‐
24 ally well supported. The API may change without publicized notice,
25 while an advancement of the minor version (e.g. 1.1.x to 1.2.x) indi‐
26 cates such a change.

28 Please report bugs and provide feedback at the e-mail address given in
29 the REPORTING BUGS section. Patches and code enhancements are also
30 welcome.
31
33 This program follows the usual GNU command line syntax, with long
34 options starting with two dashes (`-').
35
36 Here is a summary of the supported options:
37
38 -m, --model=id
39 Select radio model number. See model list (use 'rigctl -l').
40 NB: rigswr (or third party software) will use rig model 1901
41 when using rpc.rigd.
42
43 -r, --rig-file=device
44 Use device as the file name of the port the radio is connected.
45 Often a serial port, but could be a USB to serial adapter. Typ‐
46 ically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc.
47
48 -s, --serial-speed=baud
49 Set serial speed to baud rate. Uses maximum serial speed from
50 rig backend capabilities as the default.
51
52 -c, --civaddr=id
53 Use id as the CI-V address to communicate with the rig. Only
54 useful for Icom rigs.
55 NB: the id is in decimal notation, unless prefixed by 0x, in
56 which case it is hexadecimal.
57
58 -p, --ptt-file=device
59 Use device as the file name of the Push-To-Talk device using a
60 device file as described above.
61 This is only needed if the radio doesn't have legacy PTT con‐
62 trol.
63
64 -p, --ptt-type=type
65 Use type of Push-To-Talk device. Supported types are RIG, DTR,
66 RTS, PARALLEL, NONE.
67 This is only needed if the radio doesn't have legacy PTT con‐
68 trol.
69
70 -C, --set-conf=parm=val[,parm=val]*
71 Set config parameter. e.g. stop_bits=2
72 Use -L option of rigctl for a list.
73
74 -v, --verbose
75 Set verbose mode, cumulative (see DIAGNOSTICS below).
76
77 -h, --help
78 Show summary of these options and exit.
79
80 -V, --version
81 Show version of rigswr and exit.
82
83 NOTE! Some options may not be implemented by a given backend and will
84 return an error. This is most likely to occur with the --set-conf
85 option.
86
88 rigswr -m 209 -r /dev/ttyS1 14000000 14290000 50000 > cswr
89
90 Scans frequencies between 14.000 MHz and 14.200 MHz with 50 kHz step on
91 a TS-850 and records VSWR measurements in file cswr.
92
93 After completion, cswr file contains the following lines:
94 14000000 1.50
95 14050000 1.31
96 14100000 1.22
97 14150000 1.07
98 14200000 1.07
99
100 Result could then be plotted with gnuplot:
101 gnuplot
102 set data style linespoints
103 set grid
104 plot "cswr"
105
107 The -v, --version option allows different levels of diagnostics to be
108 output to stderr and correspond to -v for BUG, -vv for ERR, -vvv for
109 WARN, -vvvv for VERBOSE, or -vvvvv for TRACE.
110
111 A given verbose level is useful for providing needed debugging informa‐
112 tion to the email address below. For example, TRACE output shows all
113 of the values sent to and received from the radio which is very useful
114 for radio backend library development and may be requested by the
115 developers.
116
118 rigswr exits with:
119 0 if all operations completed normally;
120 1 if there was an invalid command line option or argument;
121 2 if an error was returned by Hamlib;
122 3 if the rig doesn't have the required capabilities.
123
125 Depending on keyer/QSK setup, transmissions in CW mode may not be modu‐
126 lated thus possibly giving a wrong result. Please report this situation
127 if it happens.

131 We are already aware of the bug in the previous section :-)
