Hi Trevor,?
No that is what I queried. On that page it says that L2 is made longer than the other two inductors for a lower inductance value, but, all other filters have L2 at a higher value.?
I was inclined to make it shorter or an extra turn, 4 turns, to give a higher value, Geoff's suggestion to try Elsie bears this out, anyway I wound 3 turns on a 6mm drill and squeezed L2 slightly shorter than happy other two,?
I think I made L1 and 2 7.4mm long and L2 6.6mm long.?
