Hi Paddy,

I know some of the older controllers produced a lot of interference and  
they were subsequently modified.  Suggest you contact Airmaster, you could  
have one of the older ones. 

best regards

Hi Folks, 
I have just replaced my  original Airmaster prop controller (AC100) with 
the upgraded AC200 which uses  the magnetic speed sensor and brush unit.
This appears to be causing  interference to my VHF transmissions. The 
receiving stations report distortion  and breaking up, which is also apparent on

the sidetone.
I am led to  believe it is the prop because the interference goes away if 
the engine is  stopped or the sensor unit is disconnected. I substituted an 
ICOM receiver for  the original Bendix/King one, and it is better but not 
cured.
Has anyone  else had a similar problem, and if you have, have you managed 
to sort  it?
All the Best, Paddy
