is it from the modulator?

Most positive feedback linear oscillators depend on some sort of random noise at start-up to be amplified 'around the loop' at whatever frequency the loop is tuned to. Klystrons are no different. Any small variation will cause the secondary cavity to generate a very small signal at its' resonance. This is fed back to the primary cavity and amplified by velocity modulating the beam which, in turn, excites the secondary cavity further. This is called 'oscillator start up'.

It's actually from the noise... A little known fact.
