My new Quantum 2 Doppler starts up fine with only a light hum of the array spinning. After about 45 minutes of use the array begins to make a loud groaning sound and does not stop until turned off then on again. The radar is backstay mounted on a gimbal the environment was 65 degrees F, 70% relative humidity. Do i need to replace the unit or is this typical?
