Z-Match Antenna Tuner
This Z-Match is a link coupled all-band tuner. Two all band tank circuits cover 3-14mhz and 14-30mhz. The tank output links are selected with a very heavy duty SPDT rotary switch
Z-match tuner
Andremo ad agire sul secondo condensatore resonance o c.v. 2 perportare i segnali ascoltati al massimo livello di livello s-meter e ritoccare poic.v. 1 sempre per il miglior risultato in ricezione
Balanced ATU
An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
FT-817 2-Tuner
The capacitor had to be small, I had the choice of two, one of 140pf and one of 100pf, Ichose the latter, as neither the rotor or stator were grounded
The Balanced Universal ATU
It is possible with only two components of a LC circuit to build a symmetrical ATU without taps and coupling links

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
