I dunno about the HAM crowd, but on CB, we throttled people who had those,
other than for skip QSO.

Anyone knows a circuit for this ?

More info, but no diagram http://history.nasa.gov/alsj/quindar.html

Rv!

Try a search using "Tone Burst Curcuits"

You should be to find something you can use.

...but anyway I still need a circuit to create a tone
on PTT push and release!

Time to play with a PIC? Use this for PTT delays and the
two tones system or to generate timing and a CTCSS tone.
I prefer the latter. Of course this could be done discretely
for CTCSS using many forms of oscillator and logic.
