I have a Model 5 Vixen c/w 912UL. Navcom is a Terra 960. My problem is EXCESSIVE engine or electrical induced static and background noise when transmitting. It is so bad the tower cannot read me at all.

Today I temporarily installed a secondary battery (sealed unit from a small golf trundler) and connected this directly to the NavCom. It works great.

Has anyone tried the "Smoothy" from Miracle Antenna @ 129 dollars? I would gladly pay up if this would solve the issue.

Any SUGGESTIONS?? I have checked all the grounds, antenna connections, etc. It works great with the engine off!!

Cheers
