Important news:

The ko4bb.com site will be moving to a new home. The traffic has slowly but surely increased over the years and our current home is simply not big enough.
I have been advised that this site could be shut down without notice, so I have temporarily suspended manual downloads until the new site is up (you will get a 404 Page not found when trying to download).
Do not be concerned, none of the manuals will be lost in the process (they have already been transferred to the new site). However, it would be appreciated if you could delay uploading new material until the transition is complete, in a week at the most.
For a quick look at how the site has evolved over the last 7 years, check the Statistics page.
Thank you for your patience.
Didier KO4BB, sysadmin.

Tone Generator

Go To Download Page Now!


This program is designed to generate audio tone(s) using your sound card.

It can generate one or two tones, and/or pink noise, simultaneously if desired.

Generating two tones simultaneously can be useful to check intermodulation distorsion in audio or radio equipment.

The performance is completely driven by the sound card you are using.

This program uses DirectSound (a Windows component) to generate sound.
