Wilbur,

Stick to stuff you understand.
1. The VHF is on at a100% duty cycle so it's output is 25 watts as you
stated.
2. The RADAR has a pulsed output. The shorter the pulse the better the
resolution of the radar. I remember one 25KW radar I was repairing only used
5 watts for the magnetron.

Power consumed depends on the pulse width and the pulse repetition
frequency.
