HF/6M Antenna Tuner Preselector and Antenna Switcher
Frequency range: 2Mc...52Mc, 180m band depending on the mismatch of the antenna used and/or maximum inductance. Experimenting with the coils can be desirable

Automatic Tuner Project
The automatic antenna tuner described here is the first part of automating my station so I can run it remotely
Automatic Tuner-Transceiver Interface
This Autoamtic Tuner-Transceiver Interface (ATTI), based on my own firmware and a PIC16F876 processor, is used to control a connected transceiver when the Tune

AT-3K only has a switch position for balance line BAL to feed to an external balun
Accordatore d'antenna QRP per i 20m
Se il led si accende, significa che ci sono onde stazionarie, se il led e' spento vuol dire che esse sono molto basse
Accordatore di Antenna Tuner
La configurazione a T offre un range di impedenza piu' elevata, e permette di accordare quasi tutte le antenne

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
