Channel ping

I would need to broadcast continuously on a channel, from turning on the radio when the radio was switched off. The idea is to send an on / off, is it possible with Devention?

What do you mean by "broadcast continuously"? AFAIK, every protocol we currently support sends every channel in every packet, which is what I think "broadcast continuously" means.

Possibly I don't understand what you mean by "channel" here as well?

Thanks for the answers and sorry for the bad English. I have a "Discovery Buzzer" and can connect it before any servo, but if I'm working on the plane with the connected battery every 2 minutes I have to move the servo! By connecting the buzzer to a receiver's free channel and generating a square wave on the radio over that channel, the buzzer will not turn on until I turn off or lose the connection to the radio.

With Fabien's Signal Generator I solved the problem, thanks again ...
