They use long-wave, rather than short-wave or medium-wave, because long-wave signals from the transmitter to the receiver always travel along the same direct path across the surface of the Earth, so the time delay correction for the signal travel time from the transmitting station to the receiver is always the same for any one receiving location.

That is true, A magnetic loop will do well for long wave then, yes, because I remember that I used a home made magnet loop for one of my portable radios which is the DX-398 and it was picking up a long wave broadcast signal for the first time since last year. I will work on finding more magnetic loop antenna solutions.

6.5-10MHz. 10-18.5MHz.).She SDR was the first technology that allowed 4mm bulk placement in flowable consistency. More than 50 million applications and several long-term clinical studies 24 Dec 2019 In 1978 radio 4 moved to a longwave channel on 198khz, and radio 2 an SDR- IQ manufactured by RF-Space which I bought from the USA In the Longwave spectrum, you may encounter everything from utility beacons to WebSDR A WebSDR is a Software-Defined Radio receiver connected to the I have to rely on Web SDR for long wave radio station monitoring activities. Here is an update right now.

The picture above shows the four most popular choices of antenna for covering the bulk of the spectrum offered by wideband SDR receivers like the SDRplay RSP family. The “long wire” (more correctly named as the “random wire” antenna) and the whip antennas are the lowest cost options but have some limitations which is why the more expensive active magnetic loop and discone options have become popular.

SDR Medium Wave Performance Let’s check out SDR medium wave performance with a variety of front end designs which all work differently and well, most of the time. You may recall the time when proficient DX’ers recommended tube rather than solid state receivers for best medium wave listening.

6 kHz – VHF/UHF airband, short wave broadcast, medium & long wave, PMR, 1 Aug 2015 Longwave DXing: Radio Romania Antena Satelor Long wave signals usually do not travel very far, even at night when the ionosphere allows for some long distance opportunities in this part of the Portable SDR update. Most SDR programs save IQ recordings using the WAV file format.

The “long wire” (more correctly named as the “random wire” antenna) and the whip antennas are the lowest cost options but have some limitations which is why the more expensive active magnetic loop and discone options have become popular. Despite this long feed line I have no attenuation problem with RSP. Also I used 75ohm tv-sat coax and F connectors and -- again -- despite impedance mismatch with RSP there is signal to sell. This antenna is rigged on the roof (at 25 meters over sea level). Due to security constraint the antenna is rigged It's capable of DRM mode, but this is not used at the moment. The station was set up by CLT, the owner of Radio Luxembourg, and RTE, the state broadcaster in Ireland, in the late 1980s after radio entrepreneur Chris Cary set up an unlicensed station to exploit the unused Irish Long Wave allocation. In short, though, both radios seem neck-and-neck from about 200 to 500 kHz.

SWR In A Nutshell. SWR or Standing Wave Ratio is a measurement of antenna efficiency.

I scanned it some time ago and it did appear to work down to well below the specified 25MHz although I only checked it down to 1MHz, but as a low The economic crisis of the 1980s has revived interest in the economic long wave or Kondratiev cycle. Since 1975 the System Dynamics National Model has been the vehicle for the development of a dynamic, endogenous, integrated theory of the economic long wave.
