Audio Settings

The default sample rate and sample type should be fine for “normal” use across an ethernet network, if you wish to access your radio remotely (over the Internet) then you may want to alter these settings if the Internet connection isn’t great.

Reducing the sample rate (default 48 KHz) can be a simple way to reduce the network bandwidth requirement. Changing this to 24 Khz will result in a barely \audible change but will ½ the required network bandwidth. Also using 8 bit audio rather than 16 bit, can ½ bandwidth requirements again. It is worth noting that 8 bit PCM will result in a significant drop in audio quality. 8 bit uLaw can be a good choice though as the audio quality shouldn’t be reduced that much.

This is all done at the client (wfview) end and it requests these settings when it first connects to the server (your radio).

If it is working for you then there is no real reason to change anything!


Install and setup on Windows

Go to and download the latest Windows version of wfview and export the zip file. Run the installation exe file then run teh application.

Open a "PowerShell" and type the following command:
This will continually print out the wfview logfile which is invaluable during the setup stage. Move the windows so the printout can be seen as wfview is being setup.

More information on logfile can be found here:
