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 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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
