I found on this trip that I had more problems with RF in the computer than I have ever had. Reduced the power to 50watts and that seemed to solve the problem. When we return to MD I am going to experiment with the setup and see if I can find out a better solution. Since running mobile I think with the less than optimum antenna the more power is better.
From my experience I found that sometimes some small changes in cabling can cause problems.
