I have an FT100. Works well on 2m. My current installations is in a Dodge 2500 pickup. I am using a Hamstick on magmount for 20M.  SWR is at 2. and the meter shows up to 100W output power. My audio reports are distorted audio and hard to copy. I do not have the radio chassis itself grounded other than the power cable. I'll try grounding it, but any other thoughts?

There is a little more to it than that. Go to my web site, and look under Antenna Mounting, Grounds, and Antenna Matching.

Likely because your RF is mostly getting back into your transmitter.  

Do what Alan tells you to do.

There could also be other parameters causing the
problem such as mic gain and processor.

Another vote for RF getting into the audio. Classic symptoms.

A smoking section in a restaurant makes as much sense as a peeing section in a swimming pool.

Thanks for the thoughts. Will do. And thanks Alan for a great site. Very informative. The FT100 operates very well indoors, along with my IC751. But this is my first mobile install and I appreciate all the help.
