7.5" LW Plug-in Loopstick NDB-DX on the Tecsun PL-380


Gary DeBock
 

Hello All,
 
While running some detailed comparisons of the newly hot-rodded 7.5" LW loopstick PL-380 with a stock ICF-2010, it was discovered that the modified Tecsun is actually quite a bit more sensitive than the ICF-2010 on all frequencies below about 250 kHz. The model features a 2000 uh center-wound coil (composed of 120 turns of 40/44 Litz wire) on a type 33 ferrite bar, and is pictured at http://www.mediafire.com/i/?ditdm4ym2g25k5m .
