Use is 80 to 10 meters.


In that case I'd seriously recommend using ferrite rather than the
powdered iron core. Type 43 or one of the 70 series would be best.
Around ten turns on a fair sized core would be in the ballpark, but you
could get more detailed information from the web site of the ferrite
manufacturer.
