Back in 2011 a newly minted NDB-DXer had the chance to design what no commercial manufacturer would ever dream of building-- a portable with a Longwave-optimized loopstick. Even if a radio has Longwave band coverage, all commercial portables have Medium Wave optimized loopsticks-- typically resulting in clunker Longwave reception.
In an all-out effort (described at http://www.mediafire.com/file/38gon1pdmomrsgs/7.5inLWLS-1.doc/file
five different Longwave test loopsticks were constructed and tested at various frequencies, until the overall "winner" was chosen. The new Longwave-optimized loopstick was a game changer when installed in Ultralight radios, providing reception of Longwave TA's in Oklahoma, South American NDB's in Canada and Hawaiian NDB's on our west coast.
The new XHDATA D-808 model does have Longwave coverage, but you had better be right next door to an airport if you want to receive any NDB's with the stock model. The 7.5" Longwave loopstick described above transforms the model completely-- making it a serious LW-DXing contender, not a pretender. With SSB capability and great portability, it can provide sensitive reception of NDB's both day and night, as well as a lot of travel DXing fun. DXers well inland will have reasonable chances for Longwave TA's in season, and the model includes excellent FM, SW and AIR band reception as well. The full 16-page article for "Supercharging" the model with this 7.5" Longwave loopstick is posted at http://www.mediafire.com/file/t2989hg61vbkb5h/Supercharging_the_XHDATA_D_-808-FinalMWLW.doc/file
which includes full information for the construction and operation of both the Longwave and Medium Wave loopstick versions. Good luck to all who take the plunge!
