So for the tandem toroid, does it matter which way those are wound? ?Should they be mirror images of each other (clockwise on one, counterclockwise on the other)?

For the air cores, you are correct, either hand will suffice as
the start and end are inline, were they to be staggered as with
the Toroid cores on the atu then it would matter.
Left handed cores have a negative inductance whilst right handed
coils have a positive inductance <v, VBG>

Look at the board and think about it a
while...

?eek¡ had no idea...
In which direction are the toroids on the
ATU-100 to be wound?

If you stop and think about it
for a while it will become apparent that
for every pass through the core, while the
winding is incomplete, there will be one
pass over the core - except on the last
pass when it doesn't pass over the core
because the winding is complete. So, for
20 turns through the core , is that 18,
19, 20, 21 or 22 over the core ?

i am talking about the end of the wind
where it passes thru the hole from the
opposit side of the core and say gets
soldered in the pcb,so for example if i
have a core with 20 turns do i count 22 on
the outside of the core or 18,hope that is
clear?,cheers+73.
