This is a frustration of mine. Some report it in SNR others report it in terms of % (current snr / (max_snr-min_snr)) others its completely random.
Seems many dvb-s report arbitrary % which is stupid and many atsc report snr by 123 would be 12.3db. But there isnt any standardization around. imo everything should be reported in terms of db, why % was ever chosen is beyond logic. Is this something we can get ratified ?
