So I did the diagnostics and found the following
Inband 1
Uncorrected errors 2
Corrected errors 42427
SNR 27.9 Poor
Inband 2
Uncorrected errors 0
Corrected errors 8022
SNR 28.3 Poor
I tightened all connections, did a reboot of the dvr and did not get any substantial change to the SNR in either bands..
What's my next step?
thanks
