did you ever check in a statistically valid way, if your approach works? as i understand from the long-term discusions, consensus is, that the only way to remedy the buzz are hardware fixes. no fiddling with mixers in what dimension ever is going to solve that basic issue.
since the buzz is, iirc, related to the tx power of the fr, depending on your situation you might reach a compromise between sound quality and buzz suppression, that satisfies your needs -- but that does not help, if your situation worsens, soon the call quality declines to a level inacceptable even for the most hardened. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
