<p class="MsoNormal">Board2: Not work audio from receiver to server (to phone). From phone to radio is ok. In offline mode audio from receiver to transmitter is ok. Radio unkey courtesy tone in phone is ok. What is faulty? In offline mode audio comes from receiver
to CPU, and from CPU to transmitter. If offline mode working, audio parts is ok.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Board3: cannot write own parameters to eprom. All changes in console menu erased after repowering. Eprom ic 25080 replaced, not result. Voltages and waveforms on eprom ic pins same as in board2.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Board4: If power up, green status led flash twice, console show text menu, after this starts red tx led for 1s and board restarts.
