DXing, taken from DX, the telegraphic shorthand for "distance" or "distant", [1] is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens band radio or other two-way radio communications.
Over the last few years, FM DXing using computers became more popular then ever, people have started using different software for DXing based on their devices, as it provides more comfort and receivers can also be tuned remotely. This allows DXers to place their antennas in remote places without the need of being at the mentioned place while DXing.
Flexible steel tape enables the antenna elements to flex and not break when encountering vegetation in the forest. On the eighty meter band, two common receiver design approaches are to use either a small loop antenna or an even smaller loop antenna wound around a ferrite rod. These antennas have a bidirectional receiving pattern, with two peak ...
If the antenna main lobe patterns have a Gaussian characteristic, and the signal powers are described in logarithmic terms (e.g. decibels (dB) relative to the boresight value), then there is a linear relationship between the bearing angle φ and the power level difference, i.e. φ ∝ (P1(dB) - P2(dB)), where P1(dB) and P2(dB) are the outputs ...
Listening to shortwave broadcast stations for news and information programming is common, but for many shortwave listeners (abbreviated as "SWLs"), the goal is to receive as many stations from as many countries as possible, also known as DXing. "DXers" routinely test the limits of their antenna systems, radios and radio propagation knowledge.
An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...
The Sony ICF-SW7600G and the newer GR model are also excellent for budget minded MW dxing. More serious DXers may spend much more for a tabletop shortwave communications receiver with good performance on the lower mediumwave frequencies using an external antenna, such as the AOR 7030+, Drake R8/R8A/R8B, Icom R-75, or Palstar R-30.
Remote electrical tilt is abbreviated as RET and it is part of the Antenna Interface Standards Group's open specification for the control interface of antenna devices. [ 2 ] Occasionally, mechanical and electrical tilt will be used together in order to create greater beam tilt in one direction than the other, mainly to accommodate unusual terrain .
