If you want more difficulty, stack the two toroids
together and wind ten turns of RG-400 on them. :-)

Well, I was wondering about that, you at least did the crossover and
wound half the turns in the opposing clockwise direction, I HOPE! ;-)

Even though this guy:

poses an argument against it!

And, this guy:

implies, "What the heck, wind 30T on a junk-box ferrite rod and do 160m!"

The main advantage I see for the crossover is that the output
is on the opposite side of the toroid from the input. :-)
