Toroid & balun Links →
1:1 current choke balunn
A 1:1 balun It offeres a almost flat swr curve from 1 to 30 MHz
1:4 Balun for 80m through 10m
Made from Amidon FT-114-43 core, 16 gauge speaker wire, and tie wraps
1:4 balun, 50 ohm unbalanced to 200 ohm balanced
Of course you can not take every ferrite core, it must already be suitable for high frequency shortwave
4:1 Voltage balun
The length of enamelled copper wire per winding for the T-200-2 powdered iron toroid core is determined by length per winder = 50mm per turn plus 200mm tails

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
