But dear Pix,
Why are you talking about Rxlevel Sub? These are the measurements taken from TEMS, for which I think that it is CODED in TEMS that when DTX is off, RXlev Full only matters and Rxlev Sub is not calculated. Which is why TEMS is displaying -126 only. Have you seen the snap I uploaded?
P.S. Where are you located in S-E Asia by the way?
