I've just uploaded a two-page article "
The Slider
e100 as a Varicoupler" to the Ultralight Files area of
DXer.ca The article is a companion to Gary DeBock's EXCELLENT
article analyzing Four Variants of the e100 as a DXing tool. My short
article describes connecting the ferrite bar of the Slider e100 to
outside antennas and using the properties of the Slider to create a very
narrow RF window through which to seek weak signals with the e100. This
article is of special interest to people operating the e100 in an urban
environment.
I was very pleased with my strategy of connecting my exterior antennas
directly to the stock loopstick of the e100 (as detailed in other
articles) as long as I was DXing from my rural location in northern
Oklahoma or at the really isolated Grayland beaches. However, when
I got to our summer cottage just south of Vancouver, BC, the e100
overloaded so badly in the RF cesspool here that it was literally
unusable. However, about three weeks ago, comments by Steve Ratzlaff and
Gary DeBock about using the Slider e100 as a "preselector" to
cut down overloading finally sunk in.... I hooked my Slider e100 to
my big antennas at the cottage and the difference was literally night and
day. Instead of having a totally unusable mish-mash of babble, I had a
DXable band... right in the heart of RF Vancouver. In seven days, I
logged almost 50 Trans-Pacific stations using the Slider as a Varicoupler
to hook the e100 to my Wellbrook Phased Array and my 70' x 100' Conti
Super Loops. My article outlines that use of the Slider
e100.
Gary's great article and my little two pager pretty well detail
everything we have developed up here on the e100.... so far. There may
still be a bit more to come.
Gary's article already has 40 hits in the first 24 hours... If you
haven't downloaded it for your files already, its highly
recommended.
