Gradual count increase at FSM19

I'm going offline for a day or so while I design and build a new linear power supply with good in and out filtering.  Well that seems not to have worked!
Still getting high peaks.

 

Things seem to be better, but for some reason counts are not showing up on Radmon!
 

Everything is fine now, thanks. I built a new PSU with loads of smoothing, and added ferrites on my probe, ethernet and mains cables. The failure in uploading was due to a faulty network socket.
 

I really don't believe it, everything runs fine for days, and suddenly again more spikes! All I can think of is mains spikes. We are having pretty awful weather at the moment, and in a rural area the power can be inconsistent. Monitoring the other day I found that the nominal 230V varied between 218 and 245!
