[HBR] Cascading IFs for better skirt selectivity?

[Ian Wilson]

If you are going to use two of the 85kc IFTs then I would think that
you could produce both good skirt selectivity and a flattish pasband
by setting one of the transformers for "overcoupled" and one of them
for "nornal" (the position of the coupling rod sets this).

The simplest way to couple the IFTs is probably just to use a
tube. You can arrange for the gain to be low (or just include it in
an AGC chain if there is one in your design).
