PCB for building a common-mode choke for amateur radio use. The standard choke uses 10 bifilar turns of 16 AWG copper wire wound around a 15mm FT114-43 toroid. This board will also accommodate a FT140 or FT240 toroid as well.

Each end may be terminated with a Molex BNC connector (P/N 0731000105), an RG-316 pigtail, or a combination of the two.

Intended as a compact, build-it-yourself PCB for inline HF common-mode choke.

Current design version: 1.4
