Balun 1:64 for end fed, PD7MAA
Build a legal limit current balun for 160 - 10 metersWind two FT240-61 ferrite core
Misure di una ferrite sconosciuta, IW2FND
In practice, just wind a coil around the core of the ferrite and measure the inductance
Creating a balun, G0KSC
For 50Ohm direct feed antennas, just a 1:1 balanced to unbalance transformer is needed
Balun di tensione 1:32
Toroid FT140 / 43 0.9 enamelled wire for primary winding

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
