Do the motors or Wi-FI produce interference at 1420 MHz?

DC motors will always produce a little RF noise. Fortunately the brushless DC motors we use are much quieter than brushed motors used by other systems. We tested the noise at 1420 MHz by placing a very sensitive Discovery Dish H-Line feed right next to the motors and yes, about 3 dB of noise spurs were visible on the spectrum when the motors run. However, having the feed right next to the motors is an extreme test and unrealistic.

In a normal setup, when the feed is mounted on the Discovery Dish, farther from the motors, and with the Dish shielding the feed from the Drive, no motor noise was visible in the spectrum.

The Wi-FI produces no noise at 1420 MHz.
