There is definitely a fault in the metallic pathway but as to the nature of the fault, I am not too sure. Initially I thought there might be a HR or semi-conducting joint. However the plots you have shown do not "fit the pattern".
Hi bc
Line looks a mess again. Regular ses and loss of ds snr. Around 5pm yesterday continual levels of crc's have appeared from practically nothing.. Would this have any significance on the potential cause of the problem?
Many thanks
