It's easy to spot because the energy of a nearby oven is stronger than almost everything else in the band.  However, the duty cycle of the magnetron producing that UHF energy isn't 100%, so there's part of every 60 Hz cycle where it's quiet.  That's when the "microwave oven avoidance" tech in some (most?) wi-fi and Bluetooth gear knows to transmit - of course at a substantial speed penalty.
