next he mentions that some of the windings need to be "scramble
wound".
could anyone please explain to me what that means or show me a picture
of what that looks like.

"scramble wound" means just what it sounds like.
uneven placement of the turns across the coil space
as contrasted with careful placement of the wire in
nice neat layers.

also if anyone has some general information or tips on winding rf
coils
and transformers, i'd greatly appreciate it.

There are many resources available online.
