Re: [Discuss-gnuradio] help -- how to implement transmitting periodic on/off tones

One would think something like this would work, but I've noticed that even if you're sending 0's to your usrp sink, the transmitter still puts out some amount of power (plenty strong enough to be detectable via a spec-an). This power goes away if you disable the transmitter via software. Does anybody know anything about this phenomenon?
