If I could reproduce here @home (on a non-modified FR during normal call), I
honestly came up with a complete analysis and ECN months ago. If I had a
CMU200, I also very likely would know more about exact parameters of call
setup that produce noise. (@Wolfgang: Werner and Graeme think I should try to
get a CMU200, urgently)
I had to visit Mickey to hear buzz first time on a normal call (without
headset connected), and even the same device with same type of SIM didn't
reproduce buzz here in my home-town (to be exact: in the places I tried here)
Strange enough, in TPE it seems much more easy to reproduce noise. Maybe they
got different setup of GSM-network there. Alas my last visit there was too
short and todo-list too long, to find the bead-fix *and* to thoroughly learn
operate CMU200 and do decent tests on peculiarities of TPE GSM-networks.
