My stats below show that Interleave is switched off and over a period of just over 10 days my CRC error rate is around 51 per hour which I believe is reasonably low for Fastpath (?).
I have noticed though with this and other "uptimes" that the SNR gradually goes down over the 10 days, eg its starts at 6.1dB and has now gardually gone down to 4.3dB. The fluctuation in the day is only around 0.2 dB.
Is this gradual reduction normal as it does not seem to be related to line noise in my opinion?
