Semplice Accordatore HF
Nel mio caso ho optato per due bobine, la prima di 11 spire avvolte su supporto di 2 cm. con del filo argentato di 2 mm, sperimentalmente si devono trovare le posizioni, sulla bobina, con l'ausilio di una pinzetta

Antenna Transmatch tuner Links →
Antenna tuner Experimental QRP hams
The primary winding of the transformer consists of 30 turns 0,9mm enameled wire
Antenna tuner QRP for antenne levy
It covers from 10 to 28 MHz but for emission powers not exceeding 10 W because the CVs used are BCL recovery
Antenna Long Wire con antenna coupler asimmetrico
Il sistema di antenna multibanda 1,6 mhz.-30 mhz
Antenne et coupleur
It consists of two coaxial coils of bare copper wire with plugs P1 and P2
Antenni tunery
The simplest connection to the tuner is the L connection. In addition to its simplicity, this circuit has unprecedented minimum losses

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
RF Inductance Calculator Mean diameter of the air core coil, measured from conductor centre to conductor centre include the wire insulation thickness, if any
