  It has been speculated that technological civilizations evolve along an
energy consumption scale first formulated by Kardashev, ranging from human-like
civilizations that consume energy at a rate of $\sim 10^{19}$ erg s$^{-1}$ to
hypothetical highly advanced civilizations that can consume $\sim 10^{44}$ erg
s$^{-1}$. Since the transmission power of a beacon a civilization can build
depends on the energy it possesses, to make it bright enough to be seen across
the Galaxy would require high technological advancement. In this paper, we
discuss the possibility of a civilization using naturally-occurring radio
transmitters -- specifically, radio pulsars -- to overcome the Kardashev limit
of their developmental stage and transmit super-Kardashev power. This is
achieved by the use of a modulator situated around a pulsar, that modulates the
pulsar signal, encoding information onto its natural emission. We discuss a
simple modulation model using pulse nulling and considerations for detecting
such a signal. We find that a pulsar with a nulling modulator will exhibit an
excess of thermal emission peaking in the ultraviolet during its null phases,
revealing the existence of a modulator.
