  The paper presents results of a numerical simulation of the stochastic
dynamics of magnetic flux in an RF SQUID loop with a Josephson point (ScS)
contact driven by a mix of band-limited Gaussian noise and low-frequency
small-amplitude sine signal, at finite temperatures $0<T<T_{c}$. A change in
the gain of the stochastically amplified weak signal with the temperature rise
is shown to be due to smearing of the energy barrier between adjacent
metastable current states of the loop. A comparison to an RF SQUID with a
tunnel (SIS) junction is done.
