Narrow band characteristics of Jovian L-bursts.

Review of some radio observations of Jupiter made during three recent apparitions using several receivers, each tuned to a slightly different frequency close to 18 MHz. Sequences of oppositely polarized bursts have been observed and also differences in polarization mode between channels 400 kHz apart. Occasionally, isolated bursts of durations of 1 to 2 sec have been found to show real drifts in frequency, as distinct from the apparent drifts shown by changing intensity across a group of features.
