I am an engineer specialized in electronics, first licenced since 1988 in amateur radio with a certain preference in DXing, constructing antennas and other electronic equipment. I have been an owner of TOP HONOR ROLL No1 ARRL DXCC since June 2009 and always a real CW operator. My main interests involve low bands, especially on 160m and my record reaches 281 countries at present. Living in the city centre while working on the low bands is very difficult. As a result, my choice of receiving and transmitting antennas is of the essence and requires solutions adapted to rural data.My aim - the hardest one - is the Pacific.
Here you can see my home made transmitting vertical antenna 30m high for the low bands with many elevated radials. XYL pretends not to notice them... hihi! Isn't it something hard to beat?
Home made remote antenna coupler at the base of the vertical antenna. The control of the coupler is a modification of the Collins C-2698 control so that it can tune fast from 40m to 160m.
A good transmitting antenna requires a good receiving antenna for the low bands...My option was a four square array antenna composed of four vertical elements. Burying feedlines of this array is undoubtedly hard work! No straight lines allowed!Hi hi!
Here are some elements of the array. They're about 7m high, situated in an olive tree garden. Four of these can really make the difference in receiving!
This is the 4 square control in my shack. The whole system is remotely operated via home made electronic devices. -It took a lot of modification of the original array to overcome the intermodulation from the existing AM stations in broadcast band. With all these modifications we get an excellent RDF and FB of the array.
My old receiving loop, now operating under new construction, next to my shack -Operating desk of the loop, fully home made and tuning electronically exactly at the operating frequency without any mechanical variable capacitor. This antenna covers 80 to 160m.
Is really grid dipping of a tank coil the last step while tuning a linear amplifier? Definitely not!
The right arrangement of a shack is always the best assistant in the battle of DXing.
Discussing ideas and techniques to remove noise and improve weak signals on 160m with Aggelos SV3RF, is surely a constructive experience.
You can always find good friends in a Hamfest to talk about problems and possible solutions to the low bands.

At last! Antennas, amplifiers etc... Here is another hobby for a DXer... TUNING THE FLOWERS!!!!
