Default Substitute wire in Trap?

Thanks for the replies everyone

Scott,
Could you please explain how I can use a grid dip meter to measure
the
resonant frequency and adjust the number of turns and/or wire spacing
to
get it where it needs to be?
I just picked up a grid dip meter but have never used one.

I'm not completely understanding the math required in figuring
inductance out...
I am able to figure out that with my coil form and number of turns the
coil I have is around 6.5uH but I cant figure out how to work wire
gauge into the equation? I have been trying to find someplace that
explains it but am unable to.
Could somebody here maybe explain how the math works when you throw
wire gauge into the equation?

Tam,
I am replacing the wire in the trap because when I was cleaning the
corrosion off,the last inch or so of the wire broke off and since the
wire is aluminum I figure I would be better off replacing it then
trying to repair.

Thanks for the help everyone
Its most Appreciated
Regards
