Some new RF45 morphologies: Wandering comb or wandering band of noise
Sometimes the problem with RF45 modulation can manifest in DARM as a wandering comb of harmonics or as a wandering band of excess noise. Here are a few plots of DARM and the RF45 modulation monitor during these times so people can recognize when this is happening in an Omega scan or spectrogram.
