Inverted L antenna for Reception
Do to it’s ease of construction, the most popular antenna for short wave reception is the inverted “L” antenna. It’s often just a random length of wire strung up as high as possible. My...

“The velocity factor (VF), also called wave propagation speed or velocity of propagation, of a transmission medium, is the speed at which a wavefront (of an acoustic signal, for example, or an electromagnetic signal,...
This preamplifier for a high impedance microphone was built into a Harris limiter/compressor which needed a line-level input. Its response is essentially flat from 20Hz-30KHz. The 10uF capacitors are 25v Tantalums, the .01uF capacitors...
