Description We propose to use the ultra-wide-bandwidth, low frequency receiver installed at the Parkes telescope in order to quantify the broad-band intermittency time scale, polarization, quasi-periodicities, and mode changing of a newly discovered pulsar, PSR J1926-0653. The pulsar is unique in its emission properties. It has multiple pulse components, that change with time (both mode- changing and sub-pulse drifting phenomena are evident). The pulsar exhibits nulls in which a few individual pulses seem to be missing. It also exhibits longer-scale (hour-scale) intermittency behaviour in which the emission switches off for long periods of time. The pulse flux densities often, but not always, seem to exhibit quasi-periodic variations. Clearly this pulsar may hold the key to many different emission phenomena and we request time on Parkes, FAST and ATCA to parameterise the pulsar and its emission properties in detail.
