Well after buying a Satlink meter It has a db and BER readout. The signal qualitt readout on it is pretty useless as it is always between 60 to 69 on all locked transponders. I never paid attention to db and ber but am learning by using this meter and have to say it is very helpful. After unwarping my 90cm and using this meter and its db and ber readouts I have totally locked in my dish to what I believe is the best quality I can get. I am trying to figure out a conversion of signal quality to db ratio but not sure it would be accurate so I am still learning. For instance on the newsource on 87 west I am hitting at a 89 quality and a 14.5 or so db, however on the NY lotto feed "Adtec2" I am hitting at 30 pct quality and a 10.2 db. Then on 91 News channel mux I am hitting at 81 pct quality and a 13.6 db. So I am curious how the receivers come up with quality and it seems like you just cant max out all tps to high 80s or 90s. Any of you have any light to shed on this info about Db or BER?
