Easy BITX: Winding TOKO Band Pass Filter Coils

| February 28, 2026 | Amateur Radio (Ham Radio) | No Comments

TOKO Band Pass Filter Coils seemed a bit tough as I am beginning the hand winding of the coils in Easy BITX after completing the assembly of other components up to the final MOSFET IRF 510. Discussed with VU2EVQ on 40m and got the advice of winding similar number of turns in each groove of the TOKO bobin which has four grooves, with 36 SWG enamelled copper wire, depending on the total number of turns needed for each band as mentioned in the manual. VU2SWX shared a web page by VK3PE which gave useful tips for winding as well.
