[EIDXA] Power supply grounding

[a.groff]

Jason,
   In general I do not, but it is possible that it may be okay...

   One problem that you can run into if you do is that there can be near 
DC/audio ground current introduced from I high current loads ( rig/amp) 
into sensitive (audio/mic ) ground paths.

   I am currently configured with three DC ground systems, High Current 
( DC power HF rigs ), Sensitive loads (audio devices ) and everything 
else. The high current loads are grounded at the radio only. The 
sensitive loads each have their own power source & path to station 
ground, and everything else shares a power supply and may have multiple 
paths to station ground.

   A bit unconventional but that's what I do..
