Diy shortwave radio receiver
WebA 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 different signals; this is in contrast to the many classical receivers that are already available via the internet..

WebThe 3 Transistor Shortwave Radio in this article is a regenerative radio designed to tune from 2Mhz through 30Mhz depending on the tuning coil used by the operator. The schematic for the radio with the major building blocks highlighted is illustrated below: Variable capacitor C5 and tuning coil L1 comprise the Tuning section. Web468 divided by 5.90 = 79' 3". The number 468 divided by the frequency above is the formula for calculating a half wave antenna length used all the time by Amateur radio operators in building many different kinds of antennas. You'll need about 435 feet of wire for this antenna plus appropriate length of coaxial cable.
