Homebrew
Pada masa-masa peralatan buatan pabrik masih mahal, umumnya rekan-rekan Amatir Radio membuat sendiri peralatan transmitter maupun receiver yang mereka gunakan. Pada masa lalu lebih sering digunakan tabung radio untuk keperluan tersebut, pada hari ini semakin banyak peralatan yang dibuat menggunakan transistor atau IC.
Proses pembuatan peralatan amatir radio sendiri sering di sebut "Homebrew". Homebrewing berbeda dengan membuat kit. Homebrewing mempunyai konotasi proses membuat peralatan menggunakan komponen dan disain yang di peroleh dari berbagai sumber dan seringkali harus berimprovisasi. Memang hasil akhirnya akan berbeda dengan peralatan amatir radio komersial buatan pabrik. Para homebrewer akan melihat dari sisi kenikmatan membuat sendiri peralatannya selain kenikmatan menguasai pengetahuan elektronika radio.
