[arm-allstar] UV-82 No audio/DTMF input

[Doug Crompton]

Dave,

 This is classic level problems. You can't just blindly turn boost off and
on. It greatly effects the RX level. After changing rxboost you have to use
item 2 RX level to make sure the level is correct. It should kick up to
5Khz.  Also PRE and DE emphasis should be disabled.
