Johnson Matchbox...adding T200 inductors?
 

Hi all..
I have a couple of T200 cores laying around that I want to wind with No 14
enameled wire.
Can anyone give me a ballpark figure how many turns I will need to wind them
to add inductance to the ends of my 275 watt Johnson Matchbox for use on 160
meters?
thanks in advance de Denton WB7TDG
