The first video shows phasing against local IBOC crud.
The second video shows the phaser in use to knock down the sideband hash from a strong local (KOA) signal, 25 miles away.
For those that like to DX in real time (unlike those using SDR overnight samplings), the phaser has much to offer.
The one being used in the videos is the Quantum Phaser and more information about it may be found here.
More on phasers next time.
