Thank you to Alberto Garlassi for submitting information about his super low parts home made FPGA software defined radio which is capable of medium wave and shortwave AM reception. What makes this design interesting is that is is created with nothing more than 3 resistors, 1 capacitor, and a low cost 30€ Lattice MachXO2 FPGA dev board. The design makes use of the FPGA's LVDS buffer input to

In this video I will show you the “hunting” of long distance commercial radio stations on Long Waves (LW). Every radio amateur knows that the reception of low frequencies (long wavelengths) is a particularly big challenge because there are a number of RF interference, atmospheric interference and industrial interference (man made RF-noise).

Radio-controlled clocks receive their time calibration signals with built-in long-wave receivers. 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. 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 On this page you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente.In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio. Introduction.

The frequency of the acoustic wave emitted by the siren is affected by the This effect is not only true for sounds but also for optical waves: when a laser beam with the is used for the transmission of long wave communications, su In this video I will show you the “hunting” of long distance commercial radio stations on Long Waves (LW). Every radio amateur knows that the reception of low frequencies (long wavelengths) is a particularly big challenge because there are a number of RF interference, atmospheric interference and industrial interference (man made RF-noise). VLF Balloon with 210m long antenna launches Sept 12 (Southgate ARC) A high-altitude balloon experiment, launched by Warsaw University of Technology, is planned to lift off September 12, carrying a VLF 210-m-long fully-airborne antenna system, transmitting on 14.2 kHz. 14.2 kHz is the former frequency of the Babice Radio Station in Poland. 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.

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously.SDR technology makes it possible that all listeners tune independently, and thus listen to differentsignals; this is in contrast to the many classical receivers that are already available via the internet.. More background information is available here.

Listening to very long waves (VLF) is fascinating with lots of interesting signal to hear, like the historical Swedish transmitter SAQ on 17.2 kHz It is a compact three-band magnetic antennaIt operates in three amateur short wavelength ranges of 20-40-80m (3.4-3.8MHz. 6.5-10MHz. 10-18.5MHz.).She SDR was the first technology that allowed 4mm bulk placement in flowable consistency.
