In a recent paper observations of electric field fluctuations in the range .5 to 25 Hz were reported, observations by the RPWS experiment on Cassini. We have found that the data presented in that paper are affected by broadband interference which appears to be generated in the spacecraft wake. Evidence for a wake instability will be presented. We present a new spectrum for electric fluctuations in the solar wind taken when the antennas are outside the wake. In earlier papers we have tried to understand why the solar wind behaves as a collisional plasma although collisions are very rare. Whether these electric fluctuations might replace the effects of collisions will be discussed.
