No, sorry if I was not clear. The 455kHz 2nd IF output of the first receiver
feeds the input of the 2nd receiver. With the two DX-394's, that results in
a quadruple conversion receiving system. This radio has pretty wide filters
for AM and SSB. For the latter, almost 7 kHz. By cascading the radios, the
combined bandwidth is inherently reduced to 3.5 kHz due to its conversion
scheme. Bandwidth for both AM and SSB can be made arbitrarily narrow with
tricky tuning.

Of course with two radios, they could alternatively be used for diversity
reception. With appropriate RF switching, they could be used as two
independent radios (with diversity as a special mode) or as cascaded radios.
Cascading itself reduces the effects of fading by providing a greater range
of AGC control.

Do you use two widely separated antennas in order to get diversity

reception
thus eliminating fade?
