Topband: NEED_PICTURE_INFO_ON_K9AY_LOOP_TRANSFORMER??

[George]

Can anyone help me with a picture on how to wind the 9:1 trifilar matching transformer for the K9AY loop I just built?
The K9AY page has everything but how to wind the coil.
The schematic looks like an auto transformer but I need to know how to wind it, which way the turns are wound etc.
What's a trifilar?
I gave up on the inverted L antenna for receiving. It may be the whole 160 season before the electric company gets around to fixing all problems on the lines causing buzzing in my receiver!
Thanks
