[Elecraft] Mobile problems

Dave,
 
In addition to filtering various points mentioned in replies to your  posting 
it is normally essential that you feed the radio DC power direct from  the 
pickup battery via a suitable protection fuse. This minimises noise to and  from 
the pickup electrical system.
 
We changed to Ford vehicles at the works QTH from our previous GMC in the  
fall of 2001. Never had any interference problems from our 100W Hi band FM  
mobiles with any of the vehicles, though SSB may be more of a problem. The  latter 
vehicles we used had the 5.2L V8 gasoline engines with fuel injection.  These 
should have been more susceptible to interference effects from 2 way  radios 
than diesel engines, but never had any problem.
 
The only problem we had with our 4 X 4 Ford pickup was the shock of going  
back to cart springs and solid axles on the front after the relative  comfort of 
the GMC with independent front suspension.
