[arm-allstar] No description in lsnodes

Doug,

   That seems vaguely familiar. Maybe that was why my TX DSP level was not
at the default setting. As I mentioned, I did run the TX level test with a
few different  radios. Some were clearly 'hotter" than others. However, for
all of the radios, I had too speak far above my normal voice to get maximum
deviation. I'll try tweaking it and see if I can adjust the gross
level while bringing the DSP setting back to its default setting.
