I had the same problem, though with a 12v T&B, and used a ferrit in the
power lead to solve it.


The only electrical noise problem I've had was when I installed a 28v T&B
which was powered of the glider's 12v supply with a solid state 12v-28v
DC-DC converter. The solution was to put an electrolytic capacitor across
the 12V supply to the converter. This was a specialized noise cancelling
capacitor and IIRC it is 150 uF with a 1.5A transient current capacity.
