A qualitative discussion is given of the role electron holes play ingenerating fine structure on the electron cyclotron maser radiation. It isargued that electron holes become deformed in phase space when interacting withan incomplete ring or horseshoe distribution which occurs in the presence ofstrong field aligned electric fields in the upward current region and in thepresence of a loss cone. This interaction is based on momentum balanceconsiderations. Deformed narrow electron holes cause steep velocity spacegradients on the ring distribution that lead to intense but narrow bandemission from their high speed sides and absorption at slightly higherfrequency from their low speed sides. The twins of banded emission andabsorption move in frequency space due to the average real space displacementof the deformed electron hole.
