GDO sensitivity

Am planning to build the GDO described by SM0VPO at
http://web.telia.com/~u85920178/use/gdo.htm using a BF245 FET (BC245
mentioned is a typo). What parameters determine the sensitivity of a GDO?
Will the sensitivity go up or down when increasing the gain in the
oscillator stage? Intuitively I would say the gain has to be just high
enough to guarantee a steady oscillation, but maybe I'm totally wrong.
