 Paul,
 
 Is the level of static interference speed related?

 After about one half hour of flight, I frequently get static on VHF comm
channels.  It usually grows with time until radio reception is marginal.
 Strangely, the static isn't a problem in the terminal area at the end of a
flight.  My antenna is a dipole, mounted inside the vertical fin.  I suspect
that a static charge on the skin may be responsible.  The skin surfaces are
not grounded.  Has anyone else had this problem?  If so, how have you solved
it?
