Signal strength 15% on HD and 85% ON Sky+
Have just got the new EPG. Signal strength on old EPG was 85% and also 85%
on Sky+ other room (4 wire installation). Now on new EPG signal strength
10-15% unchanged if wires swapped. Sky tech said - is picture OK - yes so
far -"well ignore it!"
What is going on?

Nicking from and condensing previous posters' comments - the signal
strength indication is arbitrary and of little practical significance
as long as the quality reading is reasonable and you aren't getting
picture breakup etc. other than when it is bucketing down with rain.
The quality reading indicates how many packets of data are getting
through unmolested so (as you can't have more than 100% of what is
transmitted) in practice gives an absolute indication unlike the
strength reading which is effectively calibrated in "pieces of string"
(i.e. no units are indicated and your experience suggests that a full
scale reading equates to whatever the currently-installed software
sets it to). Note also that a DodgyBox meter only indicates the state
of one frequency of many used by the box.

Thanks - seems no point in having the measurement!

Correct, I wish they would remove the "Signal Strength" Meter, it only
confuses people.

It will tell you when nothing is happening (as in "your LNB is
knackered" etc.) but the way it is implemented on a DodgyBox it is
indeed almost useless.
