"The ATU does interrupt the amp key line when the bypass SWR is too high AND there is enough forward power to endanger ATU components. It’s a fault."
Dick, I'd like to understand that a bit better. Are you saying that, with a tuning solution that gives 1.6:1, and with that tuning solution being active, that the bypass SWR is being used in the logic that controls the interrupt line? I would not have expected the bypass SWR to be used in this condition. With the tuner in-line isn't the instantaneous SWR and reflected power what controls the interrupt? In other words - isn't the bypass SWR only a factor if/when the tuner is bypassed?
