I run an IC706MkII in my 2001 Nissan Maxima.  At times I get a horrible 
hash sound even with the NB on.  Finally found it.  When it starts, 
...  Well, first; I live in Arizona and run either AC or heater all year 
'round.

That said, This hash was finally traced to the fan motor.  When the noise 
starts, I merely change the fan speed and the noise disappears, for a while!

I'm guessing the rotor on the motor gets crudded up and changing speeds 
'cleans' it up.  Anyway, consider this as a possibility!
