Description

Generates a 1004 Hz test tone.

By default, this application does not provide a Milliwatt test tone. It simply plays a 1004 Hz tone, which is not suitable for performing a milliwatt test. The m option should be used so that a real Milliwatt test tone is provided. This will include a 1 second silent interval every 10 seconds.

Previous versions of this application generated a constant tone at 1000 Hz. If for some reason you would prefer that behavior, supply the o option to get the old behavior.
