WEIRD...Running my flaps out to 4-10 degrees makes the my king 155 radio squelch engage. My flaps are set up for 10, 20 and 30 degree auto increments. So when I hit the switch for 10, they may move out, maybe 4 degrees and then the radio noise. After 10 the noise quits. This isn't an electrical noise, this is the same identical sound as if I pulled out the squelch knob. The radio is still able to transceive through this noise. The plane is 8 yrs old and this just started happening. I did nothing to induce this. Anyone?
