A very-large-diameter (approx.1/2 m) uniform electron beam is injected along a magnetic field (B/sub 0/approx. =75 G) into a dense backgroun plasma (n/sub e/approx. =10/sup 10/ cm/sup -3/). The beam drives oblique whistler waves (..omega..<..omega../sub c/<..omega../sub p/) unstable which are in resonance with the beam (..omega../k/sub parallel/approx. =..nu../sub b/) and propagate nearlyalong the resonance cone angle (costheta=k/sub parallel//kapprox. =..omega../..omega../sub c/). Growth of test waves as well as spontaneous broad-band emission reminiscent of very-low-frequency hiss are observed.
