Hello All,
For those who are interested, a major update of the May 2008 article (posted at
http://www.mediafire.com/view/404c61oxxbd992n/SuperchargingtheICF2010LargeComplete.doc
, to greatly increase the MW and LW band sensitivity of the classic Sony
ICF-2010 SSB receiver) is in the works. The updated article should be completed
during the Fall season, and will provide specific instructions for
transplanting and securing a much more sensitive loopstick into the Sony
portable's circuitry. The new loopstick will be based upon recent Litz wire
improvements.
The ICF-2010 SSB receiver is an ideal portable for tracking transoceanic DX
station carriers during Ultralight radio ocean coast DXpeditions, although its
relatively deaf stock loopstick has nowhere near the sensitivity of modern FSL
antennas. Performing the loopstick transplant will correct this deficiency, and
enable the ICF-2010 to accurately track weak SSB carriers that are easily
within the reception capability of the new FSL's. After four major DXpeditions
using a stock ICF-2010, I finally got tired of the stock model's failure to
show even a weak carrier on DU stations that managed good audio with the new
FSL's. Of course, even if an ICF-2010 owner has no interest in Ultralight
radios or DXpeditions, the loopstick transplant will still boost the MW and LW
sensitivity of the model, providing a great increase in DXing satisfaction.
For those who are interested in purchasing an ICF-2010 for this purpose, care
should be taken to obtain a fully functional model. None of these radios were
manufactured recently, and many eBay sellers are not DXers or radio
enthusiasts, but simply ordinary people trying to sell something that they
accidentally came across. Carefully check the feedback of any eBay seller
before purchasing, and make sure that they are knowledgeable about the ICF-2010
and its functions before trusting any claim of perfect performance.
