Side tone note sounds OK here. The scope indicated there is a slight
overshoot at start of note. The trailing edge is sharp but do not hear
any abnormal sound . Tried frequency from 500 to 1000 hz, tried gain from
very minimum to wide open, with and without earphones. Also treid Rx EQ
over the -20 to +20 dB range. Wonder what the scope tells you .
