// Status=review Start {wsjtx} and Select Configuration from its Setup menu. Enter the following information: - *Call Sign*: - *Grid*: - *PTT method*: choose from RTS, DTR, CAT, VOX, or None. - *PTT port*: if you will use RTS or DTR, choose a serial port, - *PSK Reporter*: check to enable sending reception reports to the {pskreporter} mapping facility. - *CW ID*: Check to send your callsign in CW after sending 73. - *CW Interval*: set the time interval for sending your CW identification. Default is 0 (never). {wsjtx} does not implement full transceiver control, but it provides a way to ensure that {wsjtx} can read and set the radio’s dial frequency. If you want this capability: - Check the box Enable CAT - Select your radio type from a drop-down list - Select a CAT port (not the same port selected for PTT control) - Set port parameters for your radio - If you use {dxlcommander} by DX Lab or {hrd} to control your transceiver, you can configure {wsjtx} to communicate with the radio through that program. Entries for these programs appear at the end of the drop-down list of supported radios. [[X11]] image::images/r3563-config-screen-80.png[align="center",alt="Configuration Screen"] For now you should leave *Split Tx* unchecked. If you are using CAT control, most radios will allow you to set *PTT method* = CAT. Some radios support two types of PTT assertion via CAT control: one takes audio input from the Mic connector, the other from a rear-panel Data connector. The simplest CAT configuration sets *Polling interval* = 0 (no polling the radio for dial frequency). {wsjtx} will then be able to set the radio’s frequency, but the program will be unaware of subsequent changes made using the radio’s panel controls. TIP: If you need an additional item in the list of devices for the CAT port, edit the configuration file wsjtx.ini and add your requirement as CATdriver=yourdriver (for example, CATdriver=/dev/ttyUSBserial ) in the group of entries marked [Common]. With most radios you can set *Polling interval* to a small number (say 1 – 3 s) and the program will follow any frequency changes made at the radio. Note that you may not be able simultaneously to control your radio from {wsjtx} and from another program. Some experimentation may be required, and you may need to refer to the documentation for your rig-control software and your radio. It is best to have the radio and any interface equipment turned on and connected before starting {wsjtx}, and to exit the program before turning your equipment off. - Click the *Test CAT Control* and Test PTT buttons to see that you have established the desired control of station functions. _ Select the devices you will use for Audio input and output. - Click OK to dismiss the Configuration window. - {wsjtx} expects your sound card to do its raw sampling at 48000 Hz. To ensure that this will be so when running under recent versions of Windows, open the system's Sound control panel and select in turn the “Recording” and “Playback” options. Click on Properties, then Advanced, and select “16 bit, 48000 Hz (DVD Quality).” CAUTION: If you are using a sound card that is also the default device for Windows sounds, be sure to turn off all such sounds so they are not transmitted over the air.
