Modified E100 Ultralight TP Loggings to Date
Very shortly a series of articles will appear in the AM-DX club bulletins giving full details on the work of three Washington state experimenters (John Bryant, Guy Atkins and myself) to create a modified Ultralight radio with unprecedented sensitivity and selectivity. This radically transformed E100 has already thrilled us with amazing TP and DU receptions, both with the new Slider loopsticks (40/44 Litz wire wound on movable coils, shifting along a ferrite bar to peak DX signals), and an extremely effective Murata CFJ455K5 narrow IF
filter, providing razor-sharp selectivity. John has also succeeded in adding an inductive coupling loop to the stock ferrite bar, providing a method for transferring external antenna DX signals through a simple plug-in jack.
In my own personal experience, this modified E100 can easily outperform any stock portable on the planet (ICF-2010, E1, etc.). Easily!
To give an indication of what it can accomplish, here is a list of the loggings made on this DX-chasing monster, both in Grayland and Puyallup, WA. All these were using the 7.5" Slider loopstick and CFJ455K5 narrow filter:

Total TP loggings on modified E100: 30 stations, 12 DX Countries... and a lot of FUN!
When the articles appear teaching you exactly how to transform your modest E100 into an outrageously effective DXing sensation, I hope you all will take advantage of this chance for a supremely exciting DX season.
