TOROID TRIFILAR
BINOCULAR TRIFILAR
Ternyata bikin kumparan(lilitan) trifilar cukup sulit bagi para pemula,tetapi ini ada tips cara untuk bikin kumparan trifilar :
Cara 1 dengan menggunakan binocular atau lebih populer ferit hidung babi,yaitu siapkan 3-4 ferit hidung babi yang biasanya untuk TV yaitu melepas kumparan asalnya balun TV dan mulai kita lilit.Potong kawat sebanyak 3 helai masing-masing dengan panjang 34 Cm dengan ukurang kawat 0,3m. Pelintir (pilin)ketiganya agak jarang jarak pelintirrannya. Gulung pada 2 lubang pada ferit hidung babi. Hubungkan seperti gambar diatas. Untuk Brown = kumparan sekunder
Green dan red = kumparan primer ,dan gabungan green dan red untuk center tapnya,jangan lupa kawat email dikupas agar bisa disolder.
Cara ke 2 dengan mencari toroid bekas lampu neon elektrik atau lampu hemat energi ,didalamnya terdapat toroid ukuran diameter 1 Cm yang dapat digunakan,lepas kumparan asalnya dan siapkan 3 helai kawat email dengan ukuran 0,4mm dengan panjang 20 Cm ,pilin ketiganya agak jarang lalu gulung melingkar sebanyak 8 lilitan, maka jadilah lilitan trifilar untuk BITX. jangan lupa ada kawat yang disatukan yaitu 2 kawat untuk center tapnya
Untuk kumparan Bifilar sama hanya jumlah kawat sebanyak 2 helai saja.
Selamat berkarya

Amateur radio

Amateur radio, often called ham radio, is both a hobby and a service in which participants, called "hams," use various types of radio communications equipment to communicate with other radio amateurs for public service, recreation and self-training.[1]
Amateur radio operators enjoy personal (and often worldwide) wireless communications with each other and are able to support their communities with emergency and disaster communications if necessary, while increasing their personal knowledge of electronics and radio theory. An estimated six million people throughout the world are regularly involved with amateur radio.[2]
The term "amateur" is not a reflection on the skills of the participants, which are often quite advanced; rather, "amateur" indicates that amateur radio communications are not allowed to be made for commercial or money-making purposes.
