Z-MATCH
The performance has been almost faultless despite both variable capacitors experience some arcing at 100 watts on two bands. However with the ability to switch in alternate tap positions this problem is over come and operations on all bands is achieved
A Simple and Flexible Tuner for QRP
A series L-C circuit can be used to match a low-impedance load, as presented by a quarter-wave
Accordatore d'antenna filare
Lunghezza del filo La massima possibile, 20 mt o giu' di li' vanno bene per la gamma 7 MHz e maggiori
Accordatore di antenna manuale per H.F 3KW

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
