That's where having the sidetone synchronized to the transmitted
signal in the PJ's is a real plus. One can adjust the weighting of the
sidetone by ear and know that the transmitted signal will sound the
same. No fancy equipment needed. Well, I guess maybe the ear can
be considered fancy equipment! Should have said, no ADDITIONAL
fancy equipment needed. :-)
