Global HF Propagation Conditions for 0400Z on 05 May, 2021

A very prominent and well known DXer sent this picture. At their request, it’s a good idea to make this particular DX Shoebox a “Guess Who..?”  If you think you know who the young operator wearing glasses is, then drop us an email DXER59[AT]GMAIL.COM and we’ll send you a signed souvenir copy of the picture […]

The post [16] What’s in the DX Shoebox today? first appeared on DX-World.

A Simple High-Performance Vertical Antenna, Digital SWR and Power Meter , The Loop on Ground Antenna, The K4ICY Antenna Launcher, CW Morse Decoder for Arduino, TX5N Raivavae, Austral Islands, VK9NT Norfolk Island 2022

Antennas/Portable
A SOTA Lightweight Portable 2m 70cm Dipole Antenna Lightweight portable QRP 2m and 70cm half wave dipole for SOTA or an emergency antenna for the 2m and 70cm Go-box.

Antennas/6M
Horizontal polarized omni directional 50MHz Antenna. This antenna is intented to use in a contest station as a second system beside the stacked yagi beam system. An omnidirectional systeem can be an advantage when it comes to short openings on wich the operator must react quickly.

Spanning 25 years, looking back from 2021 to 1997 showing DX on this Day. Do you remember working CY0AA or W5RXP/KH3 or maybe N4BQW/KH9 ? You can also check back here and see all previous DX on this Day posts. We will run with this feature generally every 3-6 days.

Антенна выполнена из алюминиевых труб разного диаметра и длины, электрически соединенных между собой режекторными фильтрами из коаксиального кабеля, намотанного на отрезках труб из изоляционного материала, для каждого диапазона, за исключением 40-метрового. Размеры антенны показаны на рис. 1 и в таблице ниже, в которой также даны значения рабочих полос частот, укорочения излучателей относительно полноразмерных антенн и… Подробнее »Грегори Кнобель, HB9FAE предложил конструкцию вертикальной траповой антенны для диапазонов 10, 12, 15, 20, 30 и 40 метров
