Re: [IRCA] 7.5" Longwave Loopstick XHDATA D-808 Portable

Hi Brandon,

<<< Thanks for another great mod. I ordered the D-808 the week before last, so should be here soon. Collecting all the bits and pieces needed for the Mw mod to be ready when the D-808 arrives. I am sticking with the SDRâs for LF/NDB, my logs here:

I'm very glad to hear that you are taking the plunge!

As far as I know, only Steve R. and I have built the Longwave version of the 7.5" loopstick D-808. It's fun for travel DXing, but it isn't exactly all I would want to take to the ocean coast to chase South Pacific NDB's. A portable, live-DXing Longwave radio is never going to come away with as many overall NDB's as an SDR, but a sizable Longwave FSL can make it competitive on single frequencies. Last month Tom R. came away with 55 South Pacific Longwave NDB's at the Rockwork ocean cliff (a west coast record), while I came away with 1 (260-NF).

Even if a radio has Longwave band coverage, all commercial portables have Medium Wave optimized loopsticks-- typically resulting in clunker Longwave reception.

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 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
