[IRCA] Vastly Improved Longwave Loopsticks for Tecsun Ultralight Radios

[d1028gary@xxxxxxx]

Hello All,

As most AM-DXers are aware, there have been amazing improvements in
Ultralight radios recently, helping the ULR-enthusiast niche group
become one of the fastest-growing segments of the entire radio hobby
community. Breakthrough accomplishments in DSP filtering, digital
search modes, memories and other innovations have made these tiny
portables astonishingly effective for AM and FM-DXing.

Unfortunately, one of the capabilities included on the recent Tecsun
DSP Ultralight models has not only remained stagnant, but seems to have
become a forgotten priority with the Tecsun design teams. Longwave band
coverage has been included on all of these recent models, but the odds
of receiving any real Longwave DX with the deaf stock loopsticks are
very long indeed. Unless a DXer lives practically on the doorstep of an
NDB station, he or she is probably out of luck.

Fortunately, ULR- DXers have recently taken the matter into their own
hands, developing Longwave-optimized 7.5" replacement loopsticks with
astonishing sensitivity on the LWBC and NDB-DXing frequencies. For
those interested, a detailed 7-page article describing the development
and DXing performance of these new LW-optimized loopsticks is posted at
http://www.mediafire.com/?845snah2h4ek9z9 , the file section of Dxer.Ca
http://www.dxer.ca/file-area/cat_view/87-ultra-light-radio-files-area/97-ulr-antennas 


and will shortly be uploaded to the Ultralightdx and Ndblist file
sections. Included is a report of the testing procedure and design
refinements in the seven LW
loopstick models, as well as a list of the various LW-TA's and LW-TP's
received with these antennas by three different DXers during the past
season. Finally, the article describes the start of the new Ultralight
NDB-DXing craze, and includes detailed procedures for a hobbyist to
build the most effective 7.5" LW Loopstick for himself (or herself).
Thanks again to all of the technical enthusiasts and DXers who have
helped the new Ultralight LWBC and NDB-DXing niche groups get started,
and we look forward to a great winter season later in the year!

73 and Good DX,
