Graybeard: The WX700 has a peak output of 10 kW, if even the standard kitchen microwave magnetron has a kilowatt of power (and can do plenty of damage) I surely do not want to be in front of any weather radar when its operational.
In any case, the critical point is that it often enough takes less than 12 seconds from setting takeoff power to reaching 80 knots before the first warnings are inhibited.
