I've built myself a common mode choke last winter (2022) but haven't created
|
|
|
|
|
this page yet. Also I haven't used it much because I haven't been very active
|
|
|
|
|
this year.
|
|
|
|
|
|
|
|
|
|
So this is basically a 140-43 toroid with 9 turns of RG174 connected to
|
|
|
|
|
BNC connectors.
