2. On  Voice, the  PTT switch works, but as I speak into the microphone (a 
T17  carbon mike) the dummy load bulb's brightness doesn't change; it 
doesn't glow  brighter as one would expect. Do you think the carbon inside has 
become  solidified and  dysfunctional? If so, any good  remedy?



Try tapping the mic smartly on your hand or a padded surface.  If the  
carbon granules have "packed," this may free them up.  The element is  
replaceable with the mic element from a 500 series WE telephone.  As I  recall from 
years ago, it is an exact fit.
 
73 and good luck,
