Hi,

Just as a follow-up on this, Joseph_B sorted out an engineer visit for me - he fitted a 15db attenuator to the cable at the point that it goes into the powered splitter.

3.0 Downstream power levels are now between -1.7 and 1.5dBmv, with SNR of between 39 and 42 - which looks a lot more reasonable.

3.1 Downstream power level is 2.9dBmV

Upstream power level remains around 43dBmv. He said that was well within the acceptable range (it certainly seems in the range described in Sephiroth's "power levels & SNR" technical posts here).

Everything still seems to be working - so thanks to everyone for the help here!

Cheers,
Dean
