An omnidirectional horizontal polarization antenna for 2 meters band in Italian
Undesrtanding three band conditions indicators to undestand current and future propagation conditions, solar flux, Ap and Kp indices
An Hentenna project for the six meters band. The standard size of standard hentenna is width 1/6 wavelength x height 1/2. The antenna build in this project is a full wavelenght antenna for the 50 MHz providing a 6.8 dbi gain.
SDRangel is an Open Source Qt5 / OpenGL 3.0+ SDR and signal analyzer frontend to various hardware TX & RX Software Defined Radio. SDRangel uses sample source plugins to collect I/Q samples from a hardware device.
SPC, series parallel capacitance, tuner project. Built properly, it will match a very wide range of impedance. It also maintains good harmonic attenuation.
A small active voltage probe antenna to aid reception on the LF bands
