LTSpice can create the wave file with any sampling freq, number of bits,
and with complete control of ramp up/down times, duty cycle etc.

I have talked with the developer of Ham Radio Deluxe about adding a
two-tone test audio file in their software.
If anyone has access to COOL EDIT PRO , ADOBE AUDITION , or similar
broadcast editing software, it should be easy to create any sort of
two-tone, three-tone, or four tone .... pulsed or unpulsed audio file
in .wav format to tune amps under lower duty cycle conditions.
Quoting "Gary H. Harmon, Jr." <gharmon@idworld.net>:
As I recall, there is some kind of device that is used to tune an
amp. It
acts like a telegraph bug sending dots.
