This Band Pass Filter (BPF) kit is for receiver input filtering. It uses the popular double-tuned-circuit which is reliable and easy to build, without needing access to any special equipment. Kits are available for 10 HF bands: 160, 80, 60, 40, 30, 20, 17, 15, 12, and 10m. The kit uses a high-quality double-sided PCB with silk-screen, solder-mask and through-hole plating. The capacitors supplied with the kit are high-quality low loss RF ceramics of the C0G type (a.k.a. NP0 - near-zero temperature coefficient).
