Thanks for the response - that is good to know. What I was referring to was the limited range on the quality meter (roughly 63 - 85). IE - could it be "trued up" to reflect the 0-100 range?
Chuck,
My Coolsat actually reads out accurately from 63% to 99% - never seen a 100% reading.
At or below 63% is an F or failing grade and above 85% is B+ or better grade. Below 63% CNR, the tuner in the Coolsat cannot discern the carrier signal from the noise.
If the meter is changed, it still won't alter how the tuner functions in this regard. All you could do is expand the scale so that no signal (roughly 63% CNR) is displayed as 0-1% and 85% and above are displayed as 99-100%. This would basically make the meter inaccurate according to the tuner's response. It would be like grading the scale on a curve.
It is difficult to imagine and more difficult to explain, but that region between 0 and 63% is actually utilized and it does represent something. It represents the NOISE floor and the condition of your LNBF for one thing. When the carrier signal is strong enough to emerge from that noise floor, it occurs at 63% and then the tuner can identify that it is no longer just background noise, but an actual signal and the bar graph begins to change from red to green.
At or above 85% it doesn't matter anymore. Your signal is so good that it is like being in a race and the guy trailing you is so far behind that it doesn't matter if you look over your shoulder 'cause he is so far behind that you won't see him.
This is difficult to explain. And I do understand your notion, but there is more to it than what you perceive.
Do you ever fish, with live bait, such as minnows? If you do, then you may understand it this way. The meter level increases as you fill your bait bucket with water. It will show an increasing level of RED until you reach the minimum water level necessary to maintain your bait and keep the minnows alive, then the meter indication turns GREEN. Then the bucket is ~63% full of water. You can use the RED level indication on the meter to judge how full the bucket is getting with water just the same as you can judge how close you are getting to a VALID signal level with your satellite dish.
Once you get over 85% water level in the bucket, it doesn't really matter anymore. As you drive your truck down the road to the lake, the water is going to slosh around and spill. By the time you get to the lake, even if you started with a bucket 99% full, you will have only 85% left, and that is plenty water to keep your minnows alive, so why worry about the water level between 85% and 99% in the first place? You have enough when it is at 85% and it won't slosh out much more than this.
This might seem to be a redneck way of describing it, but I am willing to bet that you understand it better. It gives you a visual representation of what the signal meter is looking at. The tuner is your bait bucket and the meter is just informing you what the tuner has to process.
Does this change your perception of the signal meter?
