Sudden TP1 SNR drop the other day.
I had this back from Ops yesterday regarding the sudden reduction in the TP 1 SNR level the other day which I reported to them.
Thank you for the information and feedback you have provided, It was very valuable, as per usual.
Yesterday we were able to identify the issue: it was cross polarization from the antenna uplinking to E10A-C3. This was eliminated around 14:40 UTC yesterday, which matches with your last report below.
