Presumably I do that simply by selecting each transponder on the Signal Detect screen and pressing the Enter button? If so, the results show 25-30% Strength for all transponders apart from 48200MHz, which jumps between 30% and 36%.The only reason for using the signal test on the service menu is if you suspect only one tuner is working (and clearly they are giving the same performance). So far as I know there is no option in the service menu version to change the UHF channel for the test. Using Menu >> Settings >> System >> Signal Detection doesn't offer a choice of tuner - but does allow you to survey all the tuned muxes. I recommend you do that
Quality shows as 100% for all 6 transponders.
I'm using the exactly the same RF cable for the TV and Humax - unplugging the cable and switching it between the TV and the Humax.
So if the signal strength isn't good enough for the Humax (25-30%) I'm guessing that any aerial improvements could only be marginal if the TV is already reporting 93% strength? Would it be worth getting somebody up on the roof do you think?
