I have three different bifilar wound ferrite rod chokes.

A homebrew choke measuring 127uH
A B&W FC-25A measuring 44uH.
An Ameritron/MFJ #10-15115-1 measuring 19uH.
The measurements were taken on one winding with an Elenco LCR meter.

Which one would best for grounded-grid 813's operating 160m thru 20m?

Thanks, Steve KK7UV
