Here is a picture of Dan's set, the "Litz Blitz". This set is in the
XSS Newsletter as an article in the March, 2004 issue.

Notice the FT114-61 cores and large diameter wire.
Brian uses separate cores for Lo Band/Hi band.

Steve uses a BC-221 as the basis for his BCB set.
The BC-221 is a frequency meter, WWII vintage.

I started putting the set together on January 5, 2004...way late! I
used a black plastic clipboard for the front and a clear orange
plastic one for the chassis plate. 1"x3" small boards are used to
hold up the chassis plate. I installed the coil supports during
the contest and the phone jack afterward.

This set is a modified bandpass unit, but uses two separate coil
assemblies. Each assembly consists of toroids wound on FT114-61A
cores for the antenna and detector coils. Each assembly has it own
coupling coil, connecting the antenna and detector circuits.

Here are the specs:

Lo Band
Antenna: FT114A-61, 33T #18
Couping Coil:FT-82-61, 10T ant side, 5T detector side,
   tapped every turn (det side only)
Detector: FT114A-61, 40T #18

High Band
Antenna: FT114A-61, 22T #14
Couping Coil:FT-82-61, 10T ant side, 5T detector side,
   tapped every turn (det side only)
Detector: FT114A-61, 20T #14

The audio transformer is one of the Fair Radio 100k:100 ohm units.
The headphones are Dynalec mic elements. I started with one
of the ITT diodes, then settled on one with a blue stripe
(characteristics unknown).
