Ernest, All my grounds are screwed into a single distribution block with lots of screw terminals. If you mean joining all the radio grounds into a single "pig tail" , I have not done that.

Here is a problem for you large brained engineers:
My radio is picking up noise from all the electrical motors including the alternator. I took the alternator to the shop and checked "as new". When I disconnect the coax from the radio, the noises stop, which leads me to believe the antenna coax is picking up the interference somehow. Guy at the airport suggested a clamp-on ferrite filter on the coax. I bought one tonight, but did not have time to test it.
The offenders are: fuel pumps, nose gear motor and alternator.
Any Ideas?
The fact that you have multiple antagonist leads me to believe that you might not have a common ground for your radios. 90% of radio noise problems are eliminated by simply bringing all avionics grounds to a single point.
