The Algol type eclipsing binary KZ Pav has been observed over one complete orbit (0.95 days) with the Australia Telescope Compact Array. Contemporaneous optical photometric data from the University of Southern Queensland's Observatory at Mt Kent were also collected and have been included in this multi-wavelength study. Preliminary indications are that the low levels of emission observed share similarities to those of some RS CVn binaries. The optical data show phase-linked effects which can be related to the mass transfer process of Algols. The possibility that the radio emission may be related to this process is considered.
