Print this reportWhistle glitch on OMC QPDVI found whistle glitches on the OMC QPDV channels. These glitches appear in the hundreds of Hz range and have W and M shapes. Investigation at LIGO has shown that they are caused by radio frequency signals beating in voltage controlled oscillators. We may need to investigate the radio frequency signals in the KAGRA mine.
