VOA Radiogram, program 49, during the weekend of 8-9 March 2014, asked listeners to manually set the center audio frequency to 1500 Hz. This was to determine if an MFSK32 receive-only app requires an RxID.
YouTube videos of the program included the amazing reception and mostly successful decoding of T.W. in Japan (remember that the transmitter is in North Carolina), 8 March at 1600 UTC in 17860 kHz:
