  We present preliminary results from spectral observations of four candidate
radio sources co-identified with known planetary nebulae (PNe) in the Small
Magellanic Cloud (SMC). These were made using the Radcliffe 1.9-meter telescope
in Sutherland, South Africa. These radio PNe were originally found in Australia
Telescope Compact Array (ATCA) surveys of the SMC at 1.42 and 2.37 GHz, and
were further confirmed by new high resolution ATCA images at 6 and 3 cm
(4"/2"). Optical PNe and radio candidates are within 2" and may represent a
subpopulation of selected radio bright objects. Nebular ionized masses of these
objects may be 2.6 MSol or greater, supporting the existence of PNe progenitor
central stars with masses up to 8 MSol.
