Did a test last night with the Leila system, what I think is that the warning system is triggered by narrow banded signals in the SSB 2700 Hz window. Narrow banded in this context means that Leila performs the power measurement over a much narrower part in the window than the 2700 Hz (or so) that we use for SSB.
The consequence is that you can transmit with the same power, but that a poor equalization of the transmitted power will trigger Leila. Too much bass or treble and Leila goes off, Equalize the same power and Leila stays silent. Whistle in the microphone and Leila becomes active. Insert a CW tone with the same transmit power and Leila is triggered again.
I fully understand that we should stay at acceptable power levels but in the current implementation Leila is more of a power density monitor than a power meter. Power metering should consider what we use for SSB in my opinion. Otherwise you are penalizing users for poor modulation rather than excessive transmit power. What did the makers of the Leila system want to achieve? Where is the pass-band aspect in your power measurement? What does it mean, stay below the level of the beacon, in an acceptable SSB band or in a different band, what width are we talking about? Or did you also want to warn users that they are splattering?
Please don't start the full duplex discussion again, yes I do that myself in both my permanent and my portable setup. We see Leila and act and this is how you find out how we believe Leila works.
