Quoting myself from three years ago, I propose to add an interface to read SNR in units of db/100:
A previous version of the dvb api specified the unit of snr as db/1000000 http://linuxtv.org/downloads/legacy/old/linux_dvb_api-20020304.pdf page 55, FE_READ_SIGNAL_STRENGTH "The signal-to-noise ratio, as a multiple of 10E-6 dB, is stored into *snr. Example: a value of 12,300,000 corresponds to a signal- to-noise ratio of 12.3 dB." It also defined the unit for ber (multiple of 10E-9). However it was dropped from subsequent revisions, I don't know why.
