Once wfview has been downloaded, you will need to set up the radio and the program.
Set the radio to the default CI-V address. Enable CI-V Transceive.
For radios with ethernet or wifi: Set a known username and password, and enable Network Control. Make a note of the radio’s ip address.
For radios with Serial or USB: Set the baud rate to the highest supported rate, and make a note of the rate. Here is an in-depth guide to IC-7300 radio settings.
Press  “Settings” and then press  “Radio Access”. Select  either Serial (USB) or Network.
For Serial (USB) radios:
- Select the  Serial Device
- Select the  Baud Rate
- Do not manually set the CI-V address or Model ID unless your radio is quite vintage.
For Network (ethernet or wifi) radios:
- Type in the  IP address of the radio or radio server. If you know the hostname, you may supply the hostname instead.
- Enter the  Control Port. The default is 50001 on most radios.
- Enter the  username as set on the radio.
- Enter the  password
- Select the  audio output device you wish to use. Typically this is your headset or speakers. Linux users may simply select “default” for their desktop environment’s default audio choice.
- Select the  audio input device you wish to use. Typically this is your microphone. Linux users may simply select “default” for their desktop environment’s default audio choice.
Next, for both types:
Press “Connect to Radio” (bottom of the window). If successful, the radio model number should appear in the window title bar and the lower-right corner of the window. Once working, press “Save Settings” (bottom left of the window).
