Phil.....the plating on the wire just helps prevent corrosion on the
copper wire at these frequencies. Plain copper wire would work ok. You
could tin the copper wire then wipe while hot with a rag to pseudo-tin
it......hey, a new word!

You can measure the remaining original coil wire with calipers and then
use the Handbook to convert to AWG.

A couple questions:

1.  I think that final coil "may" be wound with silver plated wire
though
I'm not sure.  I realize "normal" copper wire may have a little
additional
loss, but do you think I can get by with it ok?  Also, would it be
better if
I just "tin" the wire with a soldering iron?  I know at RF skin effect
is
important and I think that plain copper wire would have lower loss that
a
solder tined wire?

2.  Anybody know what gauge wire this coil is wound with?  I probably
won't
have a sample when I go to the store.
