_WSJT-X_ offers CAT (Computer Aided Transceiver) control of relevant
|
||
features of most modern transceivers. To configure the program for
|
||
your radio, select the *Radio* tab.
|
||
|
||
image::RadioTab.png[align="center",alt="Radio Tab"]
|
||
|
||
* Select your radio type from the drop-down list labeled *Rig*, or
|
||
*None* if you do not wish to use CAT control.
|
||
|
||
** Alternatively, if you have configured your station for control by
|
||
*DX Lab Suite Commander*, *Flrig*, *Ham Radio Deluxe*, *Hamlib NET
|
||
rigctl*, or *Omni-Rig*, you may select one of those program names
|
||
from the *Rig* list. In these cases the entry field immediately
|
||
under _CAT Control_ will be relabeled as *Network Server*. Leave
|
||
this field blank to access the default instance of your control
|
||
program, running on the same computer. If the control program runs
|
||
on a different computer and/or port, specify it here. Hover the
|
||
mouse pointer over the entry field to see the required formatting
|
||
details.
|
||
|
||
** Select *Omni-Rig Rig 1* or *Omni-Rig Rig 2* to connect to an
|
||
_Omni-Rig_ server installed on the same computer. _Omni-Rig_ will
|
||
be started automatically by _WSJT-X_.
|
||
|
||
+
|
||
|
||
* Set *Poll Interval* to the desired interval for _WSJT-X_ to query
|
||
your radio. For most radios a small number (say, 1 – 3 s) is
|
||
suitable.
|
||
|
||
* _CAT Control_: To have _WSJT-X_ control the radio directly rather
|
||
than though another program, make the following settings:
|
||
|
||
** Select the *Serial Port* or *Network Server* including the service
|
||
port number used to communicate with your radio.
|
||
|
||
+
|
||
|
||
NOTE: A special value of *USB* is available for custom USB devices
|
||
like those used by some SDR kits. This is not the same a virtual
|
||
serial port provided by USB connected transceivers and CAT
|
||
interfaces, for those use the COM or serial port name that
|
||
refers to them.
|
||
|
||
** _Serial Port Parameters_: Set values for *Baud Rate*, *Data Bits*,
|
||
*Stop Bits*, and *Handshake* method. Consult your radio's user
|
||
*guide for the proper parameter values.
|
||
|
||
+
|
||
|
||
NOTE: CAT interfaces that require handshaking will be non-responsive
|
||
until the correct *Handshake* setting is applied.
|
||
|
||
** _Force Control Lines_: A few station setups require the CAT serial
|
||
port’s *RTS* and/or *DTR* control lines to be forced high or
|
||
low. Check these boxes *only* if you are sure they are needed (for
|
||
example, to power the radio serial interface).
|
||
|
||
* _PTT Method_: select *VOX*, *CAT*, *DTR*, or *RTS* as the desired
|
||
method for T/R switching. If your choice is *DTR* or *RTS*, select
|
||
the desired serial port (which may be the same one as used for CAT
|
||
control).
|
||
|
||
+
|
||
|
||
NOTE: When using a proxy application for rig control, *CAT* is usually
|
||
the correct option for _PTT Method_ assuming the proxy
|
||
application is capable of keying your transceiver independently.
|
||
|
||
* _Transmit Audio Source_: some radios permit you to choose the
|
||
connector that will accept Tx audio. If this choice is enabled,
|
||
select *Rear/Data* or *Front/Mic*.
|
||
|
||
* _Mode_: _WSJT-X_ uses upper sideband mode for both transmitting and
|
||
receiving. Select *USB*, or choose *Data/Pkt* if your radio offers
|
||
such an option and uses it to enable the rear-panel audio line
|
||
input. Some radios also offer wider and/or flatter passbands when
|
||
set to *Data/Pkt* mode. Select *None* if you do not want _WSJT-X_
|
||
to change the radio's Mode setting.
|
||
|
||
* _Split Operation_: Significant advantages result from using *Split*
|
||
mode (separate VFOs for Rx and Tx) if your radio supports it. If it
|
||
does not, _WSJT-X_ can emulate such behavior. Either method will
|
||
result in a cleaner transmitted signal, by keeping the Tx audio
|
||
always in the range 1500 to 2000 Hz so that audio harmonics cannot
|
||
pass through the Tx sideband filter. Select *Rig* to use the
|
||
radio's Split mode, or *Fake It* to have _WSJT-X_ adjust the VFO
|
||
frequency as needed, when T/R switching occurs. Choose *None* if
|
||
you do not wish to use split operation.
|
||
|
||
When all required settings have been made, click *Test CAT* to test
|
||
communication between _WSJT-X_ and your radio. The button should turn
|
||
green to indicate that proper communication has been established.
|
||
Failure of the CAT-control test turns the button red and displays an
|
||
error message. After a successful CAT test, toggle the *Test PTT*
|
||
button to confirm that your selected method of T/R control is working
|
||
properly. (If you selected *VOX* for _PTT Method_, you can test T/R
|
||
switching later by using the *Tune* button on the main window.)
