Medium wave DX: WFED 1500 kHz Washington D.C. with at times a superb signal

Hi there, WFED historically has been one of the more difficult transatlantic MW signals to hear with decent audio, however in the past 3 months their signal has, at times, been heard very clearly. Here is another example where there's some fading, but ends with superb signal strength and audio clarity. Recorded in Oxford UK on 23/02/17 at 06:58 hrs UTC using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors). Thanks for watching.
