The Parkes 64m radio telescope did not have a standard AT local oscillator
and intermediate frequency distribution system compatible with the scheme used at the Australia Telescope Compact Array. It has therefore
lacked a degree of frequency agility and bandwidth compared with other AT antennae.
This incompatibility also limited flexibility on some programmes such as
long baseline interferometry (LBA).
The new four-channel frequency-conversion system which has been built for the Parkes
64m radio telescope increases the versatility and performance of the
instrument for many observations. It also makes Parkes compatible with
new-generation equipment and observing techniques developed under the MNRF
program for use at the ATNF's other facilities. The new conversion system has been tested at Parkes and it is anticipated that it will be in routine astronomical
use in early 1999.
