Observation 5093256: ZHUHAI-1 OVS-01 (42761)

Regarding Observation 5093256 … observing the same problem. But this time also showing three distinct signals: an intermittent signal at 25Khz below, a glitch at 100 secs. 10KHz below, and larger glitch at 430 secs. 20KHz above centre.
What is the explanation for these please? Many thanks.
