Abstract
In this report we will discuss recent determinations of wavelength and convection of Electron Cyclotron Harmonic (ECH) emissions as observed by the CRRES Plasma Wave Experiment (PWE). One motivation for this study is that these emissions may power the keV electron precipitation generating the diffuse aurora and so it is important to establish typical wave intensities. Problems encountered in doing this include wave attenuation because ECH wavelengths are typically close to the antenna length and the fact that it is difficult to study the effect of these waves on local electrons because of wave convection near the geomagnetic equator. We will also discuss a technique for approximating the emission wavelength with only one two‐element electric dipole antenna.
