The planetary radio astronomy experiment on board the Voyager spacecraft has detected bursts of nonthermal radio noise from Saturn occurring near 200 kilohertz, with a peak flux density comparable to higher frequency Jovian emissions. The radiation is right-hand polarized and is most likely emitted in the extraordinary magnetoionic mode from Saturn's northern hemisphere. Modulation that is consistent with a planetary rotation period of 10 hours 39.9 minutes is apparent in the data. 
Planetary radio astronomy observations from voyager 1 near saturn.
TLDR
The Voyager 1 planetary radio astronomy experiment detected two distinct kinds of radio emissions from Saturn, one of which is strongly polarized, bursty, tightly correlated with Saturn's rotation, and exhibits complex dynamic spectral features somewhat reminiscent of those in Jupiter's radio emission.
Planetary radio astronomy observations during the Voyager 1 Titan flyby
During the Voyager 1 Titan flyby, unusual radio emissions were observed by the planetary radio astronomy experiment in the 20- to 97-kHz frequency range. In this paper we show that Titan itself is
The relationship between Saturn kilometric radiation and the solar wind
Voyager spacecraft radio, interplanetary plasma, and interplanetary magnetic field data are used to show that large amplitude fluctuations in the power generated by the Saturn kilometric radio
Planetary Radio Astronomy Observations from Voyager 2 Near Saturn
TLDR
While crossing the ring plane at a distance of 2.88 Saturn radii, the spacecraft detected an intense noise event extending to above 1 megahertz and lasting about 150 seconds, interpreted to be a consequence of the impact, vaporization, and ionization of charged, micrometer-size G ring particles distributed over a vertical thickness of about 1500 kilometers.
Evidence of Saturn's magnetic field anomaly from Saturnian kilometric radiation high‐frequency limit

Using Voyager 1 and 2 Planetary Radio Astronomy data and reasonable assumptions about radiation beam geometry, we deduce the source locations of both polarization components of the Saturn
Observations of Non‐Thermal Radiation from Planets
Nonthermal radio emissions from earth, Jupiter, Saturn, and Uranus are reviewed. The dominant source of emission at each planet appears to be AKR-like auroral emission in the X-mode. O-mode emissions
Radio and Plasma Wave Observations at Saturn from Cassini's Approach and First Orbit
TLDR
Radio emissions from Saturn showed that the radio rotation period is now 10 hours 45 minutes 45 ± 36 seconds, about 6 minutes longer than measured by Voyager in 1980 to 1981, and many intense impulsive radio signals were detected from Saturn lightning during the approach and first orbit.
Observations of extreme ultraviolet emissions from the Saturnian plasmasphere
Emission signals from the Saturnian plasmasphere at wavelengths shortward of 800 A have been detected by the Pioneer ultraviolet photometer. The surface brightness of the emissions is about 0.3±0.2
Evidence for solar wind control of saturn radio emission
Using data collected by the Voyager 1 and 2 spacecraft in 1980 and 1981, strong evidence is presented by a direct correlation between variations in the solar wind at Saturn and the level of activity

Saturn's Magnetic Field and Magnetosphere
TLDR
The Pioneer Saturn vector helium magnetometer has detected a bow shock and magnetopause at Saturn and has provided an accurate characterization of the planetary field, indicating that the field is more uniform than those of the Earth or Jupiter and consistent with Saturn having a relatively small core.
