Thanks ff, are you sure it was the flu? Maybe the fflulu? (Just a corny joke.)
So first off I would guess that LULU uses high level modulation because the "mod tranny" is so big and beefy.
*a period of percolation...
I'm getting it, I had to use my brain. So the first section makes the oscillations for the transmitting frequency and transmits it. But it needs some audio. The second section gets the audio, amplifies it and then modulates it. This goes into the first section to get transmitted.
Toroid winding: It looks scary. But recently, after learning that men invented knitting (men can knit too), and seeing knitting projects take months to finish, I think this wouldn't be nearly as difficult. I think we were made to do menial repetitive tasks (grooming, weaving, knitting, ...) Some months ago I used knitting to calm myself down after a hard day's work. Its very therapeutic. So toroid winding probably falls in that category.
I've seen a wound toroid thing here in this speaker system. Its big and has lots of windings. Scroll 2/5ths downs the page to see it.

Edit: I'll look into the ARRL handbook that redhat recommends.
