It will probably not be obvious to most people that as of OpenVix 5.2.22, the problem of 100% signal quality reports present on most if not all tuner types should have been fixed. In particular using Signal Finder on the "Tuner config" menu page, and NOT forcing legacy stats on the "Tuner setup" pages :
* The dB figure should not be much below ~20 dB when lock is achieved, nor much above ~50 dB (precise figures will depend on whether satellite, cable, or terrestrial).
*The % figure should only be 100% for dB figures >= 42/62/50 dB for satellite/cable/terrestrial i.e. close to a main transmitter in the case of terrestrial.
* Results from different tuner models should agree within a few dB.
If these criteria are not met there would appear to be a remaining problem, probably specific to that tuner type. I am aware of a problem with one SundTek model, but are there others?
Please note that the ABM DVB-T Frequency Finder and the Terrestrial Scan plug-in use the % figure to identify the best signal when receiving from more than one transmitter - if this is always the same value then the first found rather than necessarily the best will be chosen.
