Two videos of VOA Radiogram for the weekend of 19-20 April provide examples of very bad shortwave reception. The decode of the digital text was reasonable given the conditions.

T.W. in Shimane Prefecture, Japan, provided this YouTube video of his reception and decoding of VOA Radiogram on 19 April 2014, 0930-1000 UTC, on 5745 kHz. The decode was not 100% perfect, but he is about 11000 km from the North Carolina transmitter, and there was noise on the channel (T.W. thinks it is over-the-horizon, or OTH, radar.):

Tim in Colorado (the North Carolina transmitter is beamed entirely the other direction) produced this video of his reception and decoding Saturday at 1600-1630 UTC on 17860 kHz. The decode was difficult at first, due to low signal level, but settled down after 3:30 into the video:
