We have been plagued by a similar problem and finally isolated the cause as being power noise from the voltage adapter to the wireless bridge. The adapter can have noise of its own, but we believe it is also originating from the compressor motor. We installed a 220 uF capacitor across the power leads between the voltage adapter and the bridge, and also across the power leads to the compressor. This seems to have solved the problem. Make note of whether the problem occurs mostly when the compressor is running. Power up with the air system fully charged so the compressor does not run, then drain the pressure and power up again with the compressor running, and see if there is a difference.
