Probably best not to try it in the US unless you want the FCC knocking on your door
I bet some of 'em live in the 2.4 GHz range to use unregulated spectrum.

You probably have something like a 2000 watt 2.4 GHz cavity magnetron transmitter. It's just normally got shielding around it -- your microwave oven.
Dunno if they hit a wide enough spectrum to blot out drones, though.

So, looks like not, if the frequency range is ~83 MHz wide and the magnetron in use only has bandwidth of a few MHz.
They are also frequency-hopping, meaning they constantly switch what part of the band they use, and there are a few rc radio protocols use a dual frequency system for redundancy. FRsky has one that does 2.4Ghz and 900Mhz at the same time.
So to make sure you are jamming all (commercial) drones, you need to deafen everything from ~850Mhz up to 5.9Ghz.
