A very simple receiver
With this very simple receiver, many radio amateur stations can be heard with a wire antenna of 5 meters. The receiver is tested on 80, 40, 30 and 20 meters

Installing and Running Spectrum Lab as a VLF Receiver
A PC 16 bit sound card microphone input detects small voltages at frequencies between a few Hz and 20 kHz. Essentially an antenna plugged into the microphone socket makes the sound card into a Very Low Frequency radio receiver
Low band receive antennas
This experiment was quite a bit of fun on a rainy Sunday. Very educational, especially thinking about the transformer feed and how I might use it in a transmitting version
Noise suppression with X-phase II
This device, similar devices are known as QRM eliminators or noise killers, makes it possible
Shielded Loop antenna
Shielded-Loop antennas have some nice properties that make them desirable as portable receiving antennas
Preselettore di antenna per onde lunghe 100-500 KHZ
Il pregio di questo preselettore seriale e' quello di avere una elevata selettivita', di conseguenza lo rende adatto vista la gamma di frequenza usata)alla ricezione del CW e dei radiofari NDB
