Jeff Kadet in Illinois, North America's most prominent TV DXer, was the first to decode DTV DX signals in 1999. He has logged 300 DTVs since then, including some via tropo from 800 miles away. In May, 2006 Jeff received PSIP data and decoded video from WBRA-DT-3 Roanoke VA via E-skip. This is believed to be the first DTV signal to be logged via Es above channel 2.
Jeff Kruszka in south Louisiana, VHF/UHF Digest "Photo News" editor, set the distance record for DTV reception via tropo in 2003. He received WNCN-DT-55 Goldsboro, NC at a distance of 835 miles, as well as other UHF DTVs from the Carolinas.
Girard Westerberg in Kentucky was the first to receive DTV via E-skip in 2003. He received PSIP data from KOTA-DT-2 Rapid City, SD at a distance of 1062 miles. A year later, Girard decoded perfect video frames from KOTA-DT.
Matt Sittel in Nebraska held the DTV Es distance record after receiving KVBC-DT-2 Las Vegas in 2004. The distance was 1088 miles. Matt was also the first DXer to log a second DTV signal via Es, as he had received
WKYC-DT-2 Cleveland a few weeks earlier.
In addition to Westerberg and Sittel, these DXers were among the first FIVE to receive DTV signals via Es:
Greg Barker in Indiana, Glen Hale in Kentucky, and
Steve Rich in Indiana.
Danny Oglethorpe in Louisiana (the sixth DXer to decode a DTV signal via Es) received video and PSIP data from KVBC-DT-2 Las Vegas via Es at 1238 miles in 2005, which was the longest DTV reception at the time.
Roy Barstow in Massachusetts received the first DTV signal via tropo over a distance of 900 miles in 2007. He had video from WAWS-DT-32 Jacksonville FL at 990 miles.
Inexpensive DTV converter boxes containing sixth generation chips were introduced in 2008. While the reception of DTVs via Es is still difficult for many DXers, it is now more common.
In 2009, Bob Delaney in Illinois received KNVO-DT-49 McAllen TX via tropo at 998 miles and
Pat Dyer in San Antonio received WFTS-DT-29 Tampa via tropo at 995 miles.
Mike Bugaj in Connecticut, VUD editor, received video and data from KHAS-DT-5 Hastings NE via Es at a distance of 1343 miles in June, 2009. That is currently the longest DTV reception.
