  The legacy Ooty Radio Telescope (ORT) is being reconfigured as a 264-element
synthesis telescope, called the Ooty Wide Field Array (OWFA). Its antenna
elements are the contiguous 1.92 m sections of the parabolic cylinder. It will
operate in a 38-MHz frequency band centred at 326.5 MHz and will be equipped
with a digital receiver including a 264-element spectral correlator with a
spectral resolution of 48 kHz. OWFA is designed to retain the benefits of
equatorial mount, continuous 9-hour tracking ability and large collecting area
of the legacy telescope and use modern digital techniques to enhance the
instantaneous field of view by more than an order of magnitude. OWFA has unique
advantages for contemporary investigations related to large scale structure,
transient events and space weather watch. In this paper, we describe the RF
subsystems, digitizers and fibre optic communication of OWFA and highlight some
specific aspects of the system relevant for the observations planned during the
initial operation.
