Recently a trio of fanatical Washington state
experimenters finally succeeded in creating a modified Ultralight
radio with both extreme sensitivity and extreme selectivity--
the "fully modified" Eton E100. Designed by John Bryant, Guy Atkins
and myself, this little DXing dynamo uses an innovative Slider loopstick
for great sensitivity, and a Murata CFJ455K5 IF filter for razor-sharp
selectivity.
The designer of the selectivity modification, Guy
Atkins, has written a very interesting article on this great technical
breakthrough, which gives the tiny E100 selectivity normally only found in
expensive table receivers. Guy's classic article has just been uploaded to
the Ultralight Radio File section of DXer.Ca, the home web site of the fast
growing Ultralight Radio enthusiast group. With many photos and clear
technical instructions, Guy's article can assist any technically experienced
hobbyist in creating his own super-selective E100, to join in the legendary
fun of chasing transoceanic DX with a modified pocket radio.
Enjoy!
