Hi all...I have the plan for an antenna tuner for QRP use in some
magazine or other (the same plans are in the handbook) its called a "T"
type tuner and uses a couple of torroids wound with tapped coils....My
question is this...How critical is the torroid type is this kind of
tuner...I have 2 "grey" torroids that according to the handbook are good
for .05 to .5 mhz and the plan calls for "yellow" torroids.....should I
even consider using the grey ones to try out or has anyone found that
this would be a waste of my time.....tnx for your help....
