Standalone receivers are becoming more widespread and
there is interest in 'wireless' receiver coils for a
number of potential applications. In some instances
these receivers must run without a direct connection to
the spectrometer, using a separate clock, in which case
there will generally be a random phase variation between
the transmitter and receiver. This abstract examines two
methods for proper phasing of the received signal in
asynchronous receive: recovering the phase from the
residual FID from the 180 pulse, prior to phase
encoding, and injecting an RF pilot signal outside of
the signal bandwidth through an additional probe.
