Brian Wingard's Xtal Set

Brian also used the modified bandpass approach. The detector and antenna coils are tapped, switched by ceramic insulated switches

Notice that each chassis consists of a combination
of plexiglass and poly-coated wood.

The toroids are FT82-61s, with tapped detector and antenna coils.
Note the sliver plated capacitors and ceramic switches.

The tandem verniers make for slow, precise tuning.
